# Collecting plastic in Arugam Bay, Sri Lanka
![Collecting plastic in Arugam Bay, Sri Lanka](wlab-02.jpg)
This outlines the creation of an intervention in a popular tourist destination. With tourism-related waste impacting local waste collection, establishing improved waste management systems is essential.
User Location: Pottuvil, Sri Lanka
## Steps
### Step 1: Arugam Bay
Located in Arugam Bay, a small town of approximately 150 residents on the east coast of Sri Lanka, the local economy primarily relies on tourism and seasonal fishing. However, the area faces challenges with waste management. During the tourist season, the waste management resources are heavily utilized by tourism-related businesses, leading more locals to dispose of their plastic waste through burning. Additionally, businesses often incinerate large quantities of plastic bottles, as tourists consume these in significant amounts.

![Beach clean 2.jpg](./Beach_clean_2.jpg)
![Before - no collection means cleaning efforts result in burning.jpg](./Before_-_no_collection_means_cleaning_efforts_result_in_burning.jpg)
### Step 2: What is Wasteless Arugam Bay (WLAB)
We initiated WLAB in 2018 after obtaining partial financing through a USAID grant. We provide resource management, plastic collection, and educational programs in schools, and we convert plastic waste into products. In total, we consist of three full-time employees.
![PET delivery to Eco Spindles.jpg](./PET_delivery_to_Eco_Spindles.jpg)

![WhatsApp Image 2020-02-27 at 09.07.49.jpeg](./WhatsApp_Image_2020-02-27_at_09.07.49.jpeg)
### Step 3: Our strategy
Our approach involves primarily gathering clean PET bottles from local residents and businesses. These collected PET bottles are then sold back to industry, while we retain the PE caps for our own production processes. Occasionally, we also participate in and assist with beach cleanups.
![PET at site.jpg](./PET_at_site.jpg)
![Beach clean.jpg](./Beach_clean.jpg)
![shredded waste plastic.jpg](./shredded_waste_plastic.jpg)
### Step 4: Our space
Our workspace is centrally located in Arugam Bay and comprises two shipping containers, each 20 feet (6.1 meters) in length. It enjoys convenient access to the main road, frequented by tourists engaging in leisure activities such as dining and surfing. This location provides excellent visibility for educational opportunities on various topics.

![Project site by night.jpg](./Project_site_by_night.jpg)
![Children watching info videos on site.jpg](./Children_watching_info_videos_on_site.jpg)
### Step 5: Focus on tourists
The emphasis is on collecting plastic from the tourism industry, which generates a significant quantity of PET bottles. These bottles are in demand to be transformed into recycled polyester yarn. Furthermore, handling these bottles is manageable since they are typically clean. This initiative addresses the issue of PET bottles overwhelming waste management systems.
![recycled Polyester yarn for testing in handloom 2.jpg](./recycled_Polyester_yarn_for_testing_in_handloom_2.jpg)
![shredded bottle caps.JPG](./shredded_bottle_caps.JPG)
![Storage shed filling up.jpg](./Storage_shed_filling_up.jpg)
### Step 6: Provide alternatives
Our water refill system is public, and anyone may refill for free. Ultimately, we aim to reduce the accumulation of all these bottles. A tourist destination devoid of plastic bottles would be preferable to one with extensive collections of PET bottles.
![IMG-20200114-WA0009.jpg](./IMG-20200114-WA0009.jpg)
![IMG_4944.JPG](./IMG_4944.JPG)
### Step 7: Bins
We have distributed more than 60 bins throughout the town to hotels, restaurants, resorts, mosques, and shops. Initially provided free of charge, we have since considered requiring a deposit. A well-executed paint job enhances the message. Our bins feature a prominent sticker specifying the types of plastic collected and encourages individuals to seek alternatives.
![Collection barrel wit sticker.png](./Collection_barrel_wit_sticker.png)
### Step 8: Benefits for partners
As awareness of plastic waste grows among tourists and hotels, it becomes essential for businesses to appear proactive. Consequently, convincing business owners to adopt our bins is relatively straightforward. However, it is important to have credible staff members approach these businesses, fostering trust in our intention to achieve positive outcomes.
![Collection at remote beach.jpg](./Collection_at_remote_beach.jpg)
### Step 9: Transport
To collect and transport resources, we sought an engaging and visually appealing mode of transport. We enhanced a traditional tuk tuk with striking illustrations by a local artist.
![Collection vehicle.JPG](./Collection_vehicle.JPG)
![WLAB Three Wheeler 4.jpg](./WLAB_Three_Wheeler_4.jpg)
![WLAB Three Wheeler 1.jpg](./WLAB_Three_Wheeler_1.jpg)
### Step 10: Daily collection
Every week, we take our tuk tuk to gather plastic from various locations. During peak season, we drive and collect daily as the volume increases significantly with the arrival of tourists.
![Unloading PET collection.jpg](./Unloading_PET_collection.jpg)
![Bottle flying onto tuk.jpg](./Bottle_flying_onto_tuk.jpg)
### Step 11: Volumes
We collect approximately 1.1 tons (1 metric ton) monthly, which is only a part of what remains available for collection. Gathering materials from the local community proves particularly challenging. It is feasible to amass over 4.4 tons (4 metric tons) of PET alone each month. However, the cost of collection is high while the market price for PET is low.
![Storage shed filling up.jpg](./Storage_shed_filling_up.jpg)
![PET at site.jpg](./PET_at_site.jpg)
### Step 12: Sorting
Upon arrival at our workspace, we allocate significant time to separate the bottle caps from the PET bottles, organizing them into the correct bags and containers. This task is performed by our staff, occasionally with assistance from visitors.
![Green bottle lids.JPG](./Green_bottle_lids.JPG)
![Orange bottle lids.JPG](./Orange_bottle_lids.JPG)
![Blue bottle lids.JPG](./Blue_bottle_lids.JPG)
### Step 13: Baling
To optimize transport efficiency, we compact our PET bottles into bales. Each bale comprises 700 to 800 bottles and weighs approximately 50.7 pounds (23 kg).
![baled PET.JPG](./baled_PET.JPG)
### Step 14: Products
With the polyethylene (PE) bottle caps collected, we produce various items such as key rings, surf wax combs, buttons, and buckles. These products are utilized internally, sold to individuals, or supplied to wholesalers.
![recycled plastic buckles.jpg](./recycled_plastic_buckles.jpg)
![recycled plastic souvenier 2.jpg](./recycled_plastic_souvenier_2.jpg)
![Recycled plastic button.JPG](./Recycled_plastic_button.JPG)
### Step 15: The money bit
We collect bottles free of charge from hotels and resorts. The collected PET is sold back to the industry for 55 Sri Lankan Rupees per kilogram (about 0.26 €). Products made from bottle caps are high-margin items. Greater value addition improves margins, as bulk selling raw materials is a low-margin operation requiring significant scale.
![IMG-20181115-WA0011.jpg](./IMG-20181115-WA0011.jpg)
![IMG-20181115-WA0014.jpg](./IMG-20181115-WA0014.jpg)
### Step 16: Connecting with the industry
Sri Lanka boasts advanced companies capable of converting PET into polyester yarn. However, the lack of competition results in monopolistic pricing. A similar issue affects the glass industry, where a single buyer dictates pricing.
![IMG-20181115-WA0005.jpg](./IMG-20181115-WA0005.jpg)
### Step 17: The 3 most important things to start
We have been operating for two years. Although beginning can seem daunting, establishing a full operation from the start is not necessary. Essential elements to start are:
- a dedicated team,
- adequate space,
- and most importantly, a suitable target area.
The objective of a collection operation should be to maximize collection while minimizing driving. Tourist areas are ideal due to the significant volume of waste generated by large gatherings in confined spaces.
We hope this provides assistance in getting started. Concluding with an invitation to view the video demonstrating our operations.

### Step 2: What is Wasteless Arugam Bay (WLAB)
We initiated WLAB in 2018 after obtaining partial financing through a USAID grant. We provide resource management, plastic collection, and educational programs in schools, and we convert plastic waste into products. In total, we consist of three full-time employees.

### Step 3: Our strategy
Our approach involves primarily gathering clean PET bottles from local residents and businesses. These collected PET bottles are then sold back to industry, while we retain the PE caps for our own production processes. Occasionally, we also participate in and assist with beach cleanups.

<Image src={import('./Beach_clean.jpg')} alt="Beach clean.jpg" />
<Image src={import('./shredded_waste_plastic.jpg')} alt="shredded waste plastic.jpg" />
### Step 4: Our space
Our workspace is centrally located in Arugam Bay and comprises two shipping containers, each 20 feet (6.1 meters) in length. It enjoys convenient access to the main road, frequented by tourists engaging in leisure activities such as dining and surfing. This location provides excellent visibility for educational opportunities on various topics.

<Image src={import('./Children_watching_info_videos_on_site.jpg')} alt="Children watching info videos on site.jpg" />
### Step 5: Focus on tourists
The emphasis is on collecting plastic from the tourism industry, which generates a significant quantity of PET bottles. These bottles are in demand to be transformed into recycled polyester yarn. Furthermore, handling these bottles is manageable since they are typically clean. This initiative addresses the issue of PET bottles overwhelming waste management systems.

<Image src={import('./shredded_bottle_caps.JPG')} alt="shredded bottle caps.JPG" />
<Image src={import('./Storage_shed_filling_up.jpg')} alt="Storage shed filling up.jpg" />
### Step 6: Provide alternatives
Our water refill system is public, and anyone may refill for free. Ultimately, we aim to reduce the accumulation of all these bottles. A tourist destination devoid of plastic bottles would be preferable to one with extensive collections of PET bottles.
<Image src={import('./IMG-20200114-WA0009.jpg')} alt="IMG-20200114-WA0009.jpg" />
<Image src={import('./IMG_4944.JPG')} alt="IMG_4944.JPG" />
### Step 7: Bins
We have distributed more than 60 bins throughout the town to hotels, restaurants, resorts, mosques, and shops. Initially provided free of charge, we have since considered requiring a deposit. A well-executed paint job enhances the message. Our bins feature a prominent sticker specifying the types of plastic collected and encourages individuals to seek alternatives.
<Image src={import('./Collection_barrel_wit_sticker.png')} alt="Collection barrel wit sticker.png" />
### Step 8: Benefits for partners
As awareness of plastic waste grows among tourists and hotels, it becomes essential for businesses to appear proactive. Consequently, convincing business owners to adopt our bins is relatively straightforward. However, it is important to have credible staff members approach these businesses, fostering trust in our intention to achieve positive outcomes.
<Image src={import('./Collection_at_remote_beach.jpg')} alt="Collection at remote beach.jpg" />
### Step 9: Transport
To collect and transport resources, we sought an engaging and visually appealing mode of transport. We enhanced a traditional tuk tuk with striking illustrations by a local artist.
<Image src={import('./Collection_vehicle.JPG')} alt="Collection vehicle.JPG" />
<Image src={import('./WLAB_Three_Wheeler_4.jpg')} alt="WLAB Three Wheeler 4.jpg" />
<Image src={import('./WLAB_Three_Wheeler_1.jpg')} alt="WLAB Three Wheeler 1.jpg" />
### Step 10: Daily collection
Every week, we take our tuk tuk to gather plastic from various locations. During peak season, we drive and collect daily as the volume increases significantly with the arrival of tourists.
<Image src={import('./Unloading_PET_collection.jpg')} alt="Unloading PET collection.jpg" />
<Image src={import('./Bottle_flying_onto_tuk.jpg')} alt="Bottle flying onto tuk.jpg" />
### Step 11: Volumes
We collect approximately 1.1 tons (1 metric ton) monthly, which is only a part of what remains available for collection. Gathering materials from the local community proves particularly challenging. It is feasible to amass over 4.4 tons (4 metric tons) of PET alone each month. However, the cost of collection is high while the market price for PET is low.
<Image src={import('./Storage_shed_filling_up.jpg')} alt="Storage shed filling up.jpg" />
<Image src={import('./PET_at_site.jpg')} alt="PET at site.jpg" />
### Step 12: Sorting
Upon arrival at our workspace, we allocate significant time to separate the bottle caps from the PET bottles, organizing them into the correct bags and containers. This task is performed by our staff, occasionally with assistance from visitors.
<Image src={import('./Green_bottle_lids.JPG')} alt="Green bottle lids.JPG" />
<Image src={import('./Orange_bottle_lids.JPG')} alt="Orange bottle lids.JPG" />
<Image src={import('./Blue_bottle_lids.JPG')} alt="Blue bottle lids.JPG" />
### Step 13: Baling
To optimize transport efficiency, we compact our PET bottles into bales. Each bale comprises 700 to 800 bottles and weighs approximately 50.7 pounds (23 kg).
<Image src={import('./baled_PET.JPG')} alt="baled PET.JPG" />
### Step 14: Products
With the polyethylene (PE) bottle caps collected, we produce various items such as key rings, surf wax combs, buttons, and buckles. These products are utilized internally, sold to individuals, or supplied to wholesalers.
<Image src={import('./recycled_plastic_buckles.jpg')} alt="recycled plastic buckles.jpg" />
<Image src={import('./recycled_plastic_souvenier_2.jpg')} alt="recycled plastic souvenier 2.jpg" />
<Image src={import('./Recycled_plastic_button.JPG')} alt="Recycled plastic button.JPG" />
### Step 15: The money bit
We collect bottles free of charge from hotels and resorts. The collected PET is sold back to the industry for 55 Sri Lankan Rupees per kilogram (about 0.26 €). Products made from bottle caps are high-margin items. Greater value addition improves margins, as bulk selling raw materials is a low-margin operation requiring significant scale.
<Image src={import('./IMG-20181115-WA0011.jpg')} alt="IMG-20181115-WA0011.jpg" />
<Image src={import('./IMG-20181115-WA0014.jpg')} alt="IMG-20181115-WA0014.jpg" />
### Step 16: Connecting with the industry
Sri Lanka boasts advanced companies capable of converting PET into polyester yarn. However, the lack of competition results in monopolistic pricing. A similar issue affects the glass industry, where a single buyer dictates pricing.
<Image src={import('./IMG-20181115-WA0005.jpg')} alt="IMG-20181115-WA0005.jpg" />
### Step 17: The 3 most important things to start
We have been operating for two years. Although beginning can seem daunting, establishing a full operation from the start is not necessary. Essential elements to start are:
- a dedicated team,
- adequate space,
- and most importantly, a suitable target area.
The objective of a collection operation should be to maximize collection while minimizing driving. Tourist areas are ideal due to the significant volume of waste generated by large gatherings in confined spaces.
We hope this provides assistance in getting started. Concluding with an invitation to view the video demonstrating our operations.

# Dry materials for higher quality products
![Dry materials for higher quality products](Precious_Plastic_Thumbnail.jpg)
When producing items with advanced materials such as industrial waste, drying granulate is essential. This guide explains how to dry granulate efficiently and cost-effectively, which is crucial for creating high-quality products like 3D printing filament.
Check the How-To video here: [Watch Video](https://youtu.be/dkm_gXxX2pk)
User Location: Darmstadt, Germany
## Steps
### Step 1: When and why to dry
There are two main types of polymers: polar and nonpolar. Nonpolar materials typically do not require drying. Exposing nonpolar materials, such as HDPE or PP, to water is comparable to mixing oil with water. Most other commercial polymers possess some degree of polarity and can absorb moisture from the air. Many materials are dried primarily to enhance surface appearance, as excess moisture can cause cosmetic defects like splay or silver streaking. Some polymers are compromised if processed with excessive moisture, undergoing hydrolysis, which decreases material strength. Please refer to the material overview below.
![Erste Tabelle_Zeichenfläche 1.png](./Erste_Tabelle_Zeichenflache_1.png)
### Step 2: Different drying methods
There are several DIY methods to dry polymers: using an oven, a dehydrator, or a vacuum dryer. This guide focuses on constructing a self-built dry box with silica gel. This method is preferred due to its effectiveness, affordability, simplicity, and energy efficiency. A common issue with using an oven is the risk of overheating the plastic, which can cause significant problems. Replacing the silica gel with a household dehydrator was tested, but these devices are not suitable for achieving the low humidity levels necessary for effectively drying plastic. A temperature table for different polymers is also included.
![Zweite Tabelle_Zeichenfläche 1.png](./Zweite_Tabelle_Zeichenflache_1.png)
### Step 3: Make and airtight plastic box
To construct a drybox, employ a plastic container and enhance its airtightness by applying window seals to the rim of the box.
![Step 3 (2).jpg](./Step_3_2.jpg)
![Step 3.jpg](./Step_3.jpg)
### Step 4: Get Silica Gel
You may be familiar with silica gel, commonly found in small sachets within shoeboxes to maintain dryness by absorbing moisture. Silica gel is also effective with polymers. It is advisable to place approximately 2 kilograms (4.4 pounds) in the plastic container. While there is no specific amount required, using more silica gel extends the interval between necessary drying.
![Step 4 .jpg](./Step_4_.jpg)
![Step 4 (1).jpg](./Step_4_1.jpg)
### Step 5: Get a hygrometer
A hygrometer is useful for monitoring the humidity inside the drybox. A transparent box is advantageous for continuously observing the drying process.
![Step 5.jpg](./Step_5.jpg)
![Step 5 (2).jpg](./Step_5_2.jpg)
### Step 6: Place granulate inside the box
Using a microplastic bag to hold material inside a drybox saves time and space. It keeps contents organized while allowing humidity to escape.
![Step 6.jpg](./Step_6.jpg)
![Step 6 (2).jpg](./Step_6_2.jpg)
### Step 7: Check the results
The simplest method to determine the amount of absorbed moisture is by weighing the granulate before and after drying. However, using hot air to dry granulate releases volatiles, which also reduces weight. Consequently, the weight loss does not precisely correspond to moisture loss, rendering the measurement imprecise. A more accurate method involves measuring moisture in the drying hopper using real-time dielectric property measurements. However, such sensors can be costly.
![Step 7.jpg](./Step_7.jpg)
### Step 8: Renew the silica gel
After some time, the silica gel will become saturated. To restore it, place it in the oven for one to two hours at approximately 100°C (212°F).
![Def7hdBUwAA2YTq.jpg](./Def7hdBUwAA2YTq.jpg)
### Step 9: Bonus tip
Rapid temperature changes lead to surface moisture. For instance, if a cold beverage is placed in the heat of summer, water will begin to condense on the surface. This phenomenon also occurs with polymers. Taking plastic from a cold, damp garage to a warm production area caused significant surface moisture, resulting in bubbles and inconsistencies in our 3D-printing filament.

Consequently, the weight loss does not precisely correspond to moisture loss, rendering the measurement imprecise. A more accurate method involves measuring moisture in the drying hopper using real-time dielectric property measurements. However, such sensors can be costly.

### Step 8: Renew the silica gel
After some time, the silica gel will become saturated. To restore it, place it in the oven for one to two hours at approximately 100°C (212°F).

### Step 9: Bonus tip
Rapid temperature changes lead to surface moisture. For instance, if a cold beverage is placed in the heat of summer, water will begin to condense on the surface. This phenomenon also occurs with polymers. Taking plastic from a cold, damp garage to a warm production area caused significant surface moisture, resulting in bubbles and inconsistencies in our 3D-printing filament.

# Interconnecting Zephyr Block Mould
![Interconnecting Zephyr Block Mould](HowToCOVER_ZephyrBlock_copy-18a4097a66f.jpg)
Here we will demonstrate how to create the Zephyr Block, designed in Melbourne, Australia. This block interlocks to form various structures and uses material that would otherwise be discarded.
In the folder you will find:
1. Steel sheet parts (.DXF)
2. Mould core (.STP)
3. Part identification guide
User Location: Melbourne, Australia
## Steps
### Step 1: Mould production
What you will need:
- Approx. 800x500mm (31.5x19.7 inches) sheet of 10mm (0.39 inches) steel
- 2 machined steel or alloy core elements
- Welder
- Deburring tool
- Bolts for fabrication:
- M8 x 20mm (0.31 x 0.79 inches) (8)
- M10 x 20mm (0.39 x 0.79 inches) (2)
- M12 x 25mm (0.47 x 0.98 inches) (4)
- Nuts, bolts, and washers for manufacturing:
- M10 x 110mm (0.39 x 4.33 inches) (10)
- M10 Washers (20)
- M10 Nuts or Wingnuts (10)
- ½ inch BSP Nut (stainless steel)
![Screen Shot 2023-08-29 at 2.10.27 pm-18a3f7f7a2d.png](./Screen_Shot_2023-08-29_at_2.10.27_pm-18a3f7f7a2d.png)
### Step 2: Making the parts
Using the DXF file above, cut each of the 14 pieces from 0.39 inch (10 mm) steel. Use the sheet for engraving to mark the insides of each plate and the edges of each tab to guide assembling the mold.
![IMG_7988-18a3d811d88.JPG](./IMG_7988-18a3d811d88.JPG)
### Step 3: Connecting mould components
The circle and square pieces, along with the two core components, must be permanently affixed to the specified panels:
- Connect the steel circles to the panels according to the part identification guide using M10 x 20 bolts. The circles are movable but crucial for ensuring each brick fits correctly; verify before filling the mold.
- Affix the alloy cores to each top panel, as indicated in the identification guide using M12 x 1″ bolts.
- Attach the smaller square plate to the part labeled 5/E (outer) and the larger square plate to the circle end of the 2/B/3/C core panel (outer) using M8 x ¾″ bolts.
- Finally, weld the ½″ BSP nut (stainless steel) to the 1/A panel to facilitate connection to your extruder.
![IMG_7995-18a3d81eef6.JPG](./IMG_7995-18a3d81eef6.JPG)
### Step 4: Prepare material
The mold requires approximately 3.3 pounds (1.5 kilograms) of shredded HDPE, so ensure this is prepared for insertion into the hopper.
![Screen Shot 2023-08-29 at 2.10.51 pm-18a3f806b4b.png](./Screen_Shot_2023-08-29_at_2.10.51_pm-18a3f806b4b.png)
### Step 5: Prepare machine
Attach the fitting to your extruder and activate the machine to melt the plastic.
Once prepared, feed the material into the hopper.
![Screen Shot 2023-08-29 at 7.06.27 pm-18a40902bea.png](./Screen_Shot_2023-08-29_at_7.06.27_pm-18a40902bea.png)
### Step 6: Prepare the mould + other required items
While waiting for the plastic to melt, assemble the mold by placing one of the base plates down, and inserting each tabbed end into its corresponding hole. One side connects numbers (1-10) or letters (A-J). Secure each corner with M10 bolts, washers, and nuts or wingnuts.
![IMG_7992-18a3d839fed.JPG](./IMG_7992-18a3d839fed.JPG)
### Step 7: Attach the mould
Ensure that your mold is attached to the extruder securely. The mold should be positioned upright rather than lying flat.
![IMG_7980-18a3d841a82.JPG](./IMG_7980-18a3d841a82.JPG)
### Step 8: Fill the mould
Operating a machine at 356°F (180°C) and a speed of 35 Hz, the mold will be filled in approximately 6 minutes. Observe the vent at the back of the mold for the initial sign of plastic bubbling, then turn off the machine and remove the mold.
![IMG_8005-18a3d8493e9.JPG](./IMG_8005-18a3d8493e9.JPG)
### Step 9: Opening the mould
Wearing heat-resistant gloves, position the mold horizontally on one of its plates and carefully undo each bolt and nut.
![IMG_8009-18a3d851601.JPG](./IMG_8009-18a3d851601.JPG)
### Step 10: Cool the product
Once removed from the mold, immerse in a water bath to expedite the cooling process.
![IMG_8020-18a3d85b992.JPG](./IMG_8020-18a3d85b992.JPG)
### Step 11: How we made it: Bricks for a community garden
A video overview of how we transformed 91,500 discarded plastic bottle caps into blocks for a community garden. Watch it now.
### Step 12: Explore the possibilities
Construct various structures such as office partitions, furniture, and garden beds, while reducing the accumulation of plastic waste in landfills.

Let's make plastic rope! With a bit of patience and some handcrafted dedication, you can create colorful rope from single-use plastic bags.
User Location: Praya Barat, Indonesia
## Steps
### Step 1: Recycled plastic rope in 5 easy steps!
# How to Make Plastic Rope in Five Steps
1. **Collect**
2. **Clean**
3. **Cut**
4. **Combine**
5. **Create**
Consult the PDF or view the video for a detailed, step-by-step process on crafting your own plastic rope. Feel free to explore your own creative ideas!
**Pro Tip:** After making your rope, roll it into balls between 32-328 feet (10-100 meters). You can then experiment with creating bracelets or keychains using 10-16 feet (3-5 meters), bags with 65-164 feet (20-50 meters), and wall hangings needing 328-984 feet (100-300 meters) or more. Look up traditional macrame patterns online — anything achievable with regular rope can also be attempted with plastic rope.
Enjoy the process!
## Resources
To create plastic rope from plastic bags, you'll need basic tools and materials commonly available in households. Below is a concise breakdown of the essentials used in each stage of the process.
### Tools
- Scissors (for cutting plastic bags into strips)
- Soap and water (to clean collected bags)
- Measuring tape/ruler (to ensure uniform strip widths)
### Hardware
- Flat workspace (for cutting and braiding strips)
- Drying rack or line (to air-dry washed bags)
The process relies on manual techniques rather than specialized equipment, emphasizing simplicity and sustainability. Plastic bags serve as the primary raw material.

# Low cost stool using cake mould
![Low cost stool using cake mould](how-to-stool-with-cake-mould-1831c0db512.png)
This tutorial outlines the process for preparing a stool using an inexpensive mold. A simple cake tin effectively serves as the mold.
User Location: Berlin, Germany
## Steps
### Step 1: Sourcing the material
Before commencing, it is essential to choose the type of plastic and determine how to obtain it. Commonly used are PP (Polypropylene) or HDPE (High-Density Polyethylene), which can often be sourced locally. If plastic flakes are unavailable to you, seek alternative sources.
![DSC_4127-18244ffd308.jpg](./DSC_4127-18244ffd308.jpg)
![IMG_2407-182450c4071.JPG](./IMG_2407-182450c4071.JPG)
![Merijaan_Soap Box_blue_2-1825de24a2a.jpg](./Merijaan_Soap_Box_blue_2-1825de24a2a.jpg)
### Step 2: Mould making
Customized engineered molds are often costly, particularly given the current economic situation. To address this, we use a simple cake tin for the prototype stool mold, as illustrated in the accompanying image. We obtained it from a local supermarket, and it functions adequately.
Attention:
Ensure that the bottom of the cake tin is level, as it will eventually determine the shape of the top of your stool.
![IMG_2551-1825de3767f.jpg](./IMG_2551-1825de3767f.jpg)
![IMG_2550_2-1825de38eec.jpg](./IMG_2550_2-1825de38eec.jpg)
### Step 3: Machine - oven
We utilize a compact oven adapted into a compression machine. Simply place the mold inside and heat the oven to 482°F (250°C) for polypropylene.
![IMG_2555-1825de6ecf0.jpg](./IMG_2555-1825de6ecf0.jpg)
![IMG_2556-1825de71911.jpg](./IMG_2556-1825de71911.jpg)
![IMG_2554-1825de736d8.jpg](./IMG_2554-1825de736d8.jpg)
### Step 4: Melt the seat
Fill the cake tin with your granulated material to the top and place it in the oven. Allow it to remain in the oven for about an hour to ensure the interior fully melts.
After removing it from the oven, let it cool for another hour. Once cooled, open the cake tin and remove your item.
As the top surface may not be even with this technique, use an electric planer to smooth it. Collect the excess material for future use.
![IMG_2546_2-1825de972fc.jpg](./IMG_2546_2-1825de972fc.jpg)
![IMG_2547_2-1825de99300.jpg](./IMG_2547_2-1825de99300.jpg)
![IMG_2548_2-1825de9c8e6.jpg](./IMG_2548_2-1825de9c8e6.jpg)
### Step 5: Fix legs
Initially, we experimented with wooden legs; however, securing them to the seat proved challenging. Ultimately, we opted for metal legs that can be easily screwed beneath the seat, maintaining an aesthetically pleasing appearance.
To proceed, acquire the legs from a local hardware store or online. The legs include screws. Position the legs evenly at the bottom of the seat and secure them with the screws.
Turn it over and take a seat—your elegant new stool is ready!

# Make a bowl with kitchen molds
![Make a bowl with kitchen molds](WhatsApp_Image_2023-09-24_at_20.51.11-18ac965a649.jpeg)
Create a bowl by compressing melted plastic into kitchen molds to produce items such as a vase, fruit bowl, or organizer.
User Location: Sao Paulo, Brazil
## Steps
### Step 1: Preparation
Gather the following items to begin:
- Two stainless steel bowls (of the same size or one smaller than the other)
- A pair of gloves
- A scale
- An oven set to 374°F (190°C)
- PP5 plastic
- A bucket of water
1. Weigh the plastic to approximately half the height of the larger bowl (this varies based on bowl size) and set aside.
2. Place 3.5 ounces (100 grams) into the larger bowl and put it in the oven at 374°F (190°C).
3. Wait for it to melt until it reaches the bright point (approximately 5 minutes).

![cumbuca9-18ab4a977a4.jpg](./cumbuca9-18ab4a977a4.jpg)
![cumbuca11-18ab4ab4180.jpg](./cumbuca11-18ab4ab4180.jpg)
### Step 2: Layering
The key to avoiding burning the plastic is to add layers incrementally. Determine the required amount for your mold by adding approximately 3.5 ounces (100 grams) at a time.
Once you have used the allocated amount of plastic, place the second bowl on top and return it to the oven for the final 5 to 10 minutes.
![cumbuca7-18ab4b2faea.jpg](./cumbuca7-18ab4b2faea.jpg)
![cumbuca5-18ab4b33601.jpg](./cumbuca5-18ab4b33601.jpg)
![cumbuca3-18ab4b35bbe.jpg](./cumbuca3-18ab4b35bbe.jpg)
### Step 3: Press and cool
After adding all the layers and removing from the oven, you should have nicely melted plastic ready to compress.
Take the kit bowls and press them together to ensure the plastic fills the space between them.
Balance the bowls to make them even, then place the assembly directly into a bucket of water.
Wait 5 minutes before demolding the plastic bowl. Make any necessary finishing touches, and it is ready to use.

![cumbuca13-18ab4bf24c4.jpg](./cumbuca13-18ab4bf24c4.jpg)
### Step 4: Use it
Enjoy your recycled piece as you like.
Some ideas include using it as a fruit bowl, plant pot, or organizer.

# Make a bowl with kitchen molds
<Image src={import('./WhatsApp_Image_2023-09-24_at_20.51.11-18ac965a649.jpeg')} alt="Make a bowl with kitchen molds" />
Create a bowl by compressing melted plastic into kitchen molds to produce items such as a vase, fruit bowl, or organizer.
User Location: Sao Paulo, Brazil
## Steps
### Step 1: Preparation
Gather the following items to begin:
- Two stainless steel bowls (of the same size or one smaller than the other)
- A pair of gloves
- A scale
- An oven set to 374°F (190°C)
- PP5 plastic
- A bucket of water
1. Weigh the plastic to approximately half the height of the larger bowl (this varies based on bowl size) and set aside.
2. Place 3.5 ounces (100 grams) into the larger bowl and put it in the oven at 374°F (190°C).
3. Wait for it to melt until it reaches the bright point (approximately 5 minutes).

<Image src={import('./cumbuca9-18ab4a977a4.jpg')} alt="cumbuca9-18ab4a977a4.jpg" />
<Image src={import('./cumbuca11-18ab4ab4180.jpg')} alt="cumbuca11-18ab4ab4180.jpg" />
### Step 2: Layering
The key to avoiding burning the plastic is to add layers incrementally. Determine the required amount for your mold by adding approximately 3.5 ounces (100 grams) at a time.
Once you have used the allocated amount of plastic, place the second bowl on top and return it to the oven for the final 5 to 10 minutes.

<Image src={import('./cumbuca5-18ab4b33601.jpg')} alt="cumbuca5-18ab4b33601.jpg" />
<Image src={import('./cumbuca3-18ab4b35bbe.jpg')} alt="cumbuca3-18ab4b35bbe.jpg" />
### Step 3: Press and cool
After adding all the layers and removing from the oven, you should have nicely melted plastic ready to compress.
Take the kit bowls and press them together to ensure the plastic fills the space between them.
Balance the bowls to make them even, then place the assembly directly into a bucket of water.
Wait 5 minutes before demolding the plastic bowl. Make any necessary finishing touches, and it is ready to use.

<Image src={import('./cumbuca13-18ab4bf24c4.jpg')} alt="cumbuca13-18ab4bf24c4.jpg" />
### Step 4: Use it
Enjoy your recycled piece as you like.
Some ideas include using it as a fruit bowl, plant pot, or organizer.

# Make a dog feeder
![Make a dog feeder](C57D20D4-B6B5-4E54-9A9A-1E648848CF20-18a5c41a4aa.jpeg)
A dog feeder is essentially a container designed to let your pet eat at a comfortable height. This particular method involves creating plastic sheets using compression.
User Location: Partido de General Pueyrredon, Argentina
## Steps
### Step 1: Make a plastic sheets
We need three sheets:
- Top: 10.6 x 10.6 inches (27 x 27 cm)
- Front base: 10.6 x 6.7 inches (27 x 17 cm)
- Lateral base: 9.8 x 6.7 inches (25 x 17 cm)
Thickness of the sheet: 0.4 inches (1 cm)
Material: Polystyrene

### Step 2: Plastic sheet cuts
We need to cut three circles: one for the plate base and two for the legs base.
9 inches (23 cm) Circles
For this task, we use a milling machine.

A dog feeder is essentially a container designed to let your pet eat at a comfortable height. This particular method involves creating plastic sheets using compression.
User Location: Partido de General Pueyrredon, Argentina
## Steps
### Step 1: Make a plastic sheets
We need three sheets:
- Top: 10.6 x 10.6 inches (27 x 27 cm)
- Front base: 10.6 x 6.7 inches (27 x 17 cm)
- Lateral base: 9.8 x 6.7 inches (25 x 17 cm)
Thickness of the sheet: 0.4 inches (1 cm)
Material: Polystyrene
<Image src={import('./f138fa4f-62da-43c6-b4a1-772821fd9385-18a5c433aed.JPG')} alt="f138fa4f-62da-43c6-b4a1-772821fd9385-18a5c433aed.JPG" />
<Image src={import('./PHOTO-2022-07-15-10-35-48_18-18a5c434c2a.jpg')} alt="PHOTO-2022-07-15-10-35-48 18-18a5c434c2a.jpg" />
<Image src={import('./6418d5c4-21e5-459f-89bc-80cb24d7a26b-18a5c4356fd.JPG')} alt="6418d5c4-21e5-459f-89bc-80cb24d7a26b-18a5c4356fd.JPG" />
### Step 2: Plastic sheet cuts
We need to cut three circles: one for the plate base and two for the legs base.
9 inches (23 cm) Circles
For this task, we use a milling machine.
<Image src={import('./75341237-17F1-406A-B913-860185CE4BD5-18a5c4488cd.jpeg')} alt="75341237-17F1-406A-B913-860185CE4BD5-18a5c4488cd.jpeg" />
<Image src={import('./1244E0D3-5E29-42DD-969B-76FFA97D634C-18a5c4499cc.jpeg')} alt="1244E0D3-5E29-42DD-969B-76FFA97D634C-18a5c4499cc.jpeg" />
### Step 3: Cut the sheets in half
We must cut the sheets using a bench saw. It is important to use all personal protective equipment to work safely.
<Image src={import('./DE6FA665-0D9F-4578-83BC-34E1C80FB533-18a5c46d1d2.jpeg')} alt="DE6FA665-0D9F-4578-83BC-34E1C80FB533-18a5c46d1d2.jpeg" />

# Make a simple & efficient 500mm x 300 mm sheet
![Make a simple & efficient 500mm x 300 mm sheet](196262809_344431647079441_3023982204595924153_n.jpg)
This is Zero Plastics Australia's large craft sheet design, an essential addition to any workspace.
### Materials Needed:
- Sheet press
- 800 grams (1.76 pounds) granulated plastic
- 1 aluminum frame
- 2 aluminum base plates
- Stanley knife and paint scraper (useful for gently prying apart the aluminum plates)
### Time Estimates:
- Cooking: 2030 minutes
- Cooling: 2030 minutes
- Tidy up: 510 minutes
User Location: Ballarat, Australia
## Steps
### Step 1: Preparing the mould
You need two base plates and one aluminum frame (a thick border is advisable, as it will reduce bending). Place one base plate and the aluminum frame down, fill evenly with the plastic granules, then place the second base plate on top, creating a sandwich before closing.
![224199397_367670821405034_3085572952599806449_n.jpg](./224199397_367670821405034_3085572952599806449_n.jpg)
### Step 2: Preparing the machine
Activate your machine. The temperature setting depends on the type of plastic utilized; however, this guide pertains to HDPE.
Once the temperature reaches 200°C (392°F), securely close the machine until a clicking sound is heard. Adjustments to the knob at the top may be necessary.
![2.jpg](./2.jpg)
![3.jpg](./3.jpg)
![4.jpg](./4.jpg)
### Step 3: Melting the plastic
Melting requires 20-30 minutes. Once completed, remove the aluminum plates and place them on concrete. Lay another concrete slab on top for compression. Adding weight is beneficial. Allow it to cool for 30 minutes. Exercising patience is important, as rushing this step can create problems.
![208312738_561611505248788_6036887890691209982_n.jpg](./208312738_561611505248788_6036887890691209982_n.jpg)
### Step 4: Tidy up
Use the paint scraper to gently separate the plates by inserting it into the gap. Test various mold release methods. If a better method is discovered, kindly inform us. If the sheet becomes stuck, use a Stanley knife to carefully carve it out. Take your time to trim the edges for a cleaner finish.

# Make a stool with upcycled PETG 3D print waste
![Make a stool with upcycled PETG 3D print waste](20230315_152528-18a5f104891.jpg)
In this How-To, we will instruct you on converting 3D print waste into design objects using a shredder, a sheet press, and a CNC machine.
User Location: Calenzano, Italy
## Steps
### Step 1: Collect plastic
Firstly, gather all the plastic remnants from your 3D printing activities, such as supports or defective prints. Sort the plastic by type, such as PLA, PETG, and ABS.
![Screenshot_20230830_124924_Gallery-18a5119b7de.jpg](./Screenshot_20230830_124924_Gallery-18a5119b7de.jpg)
### Step 2: Begin to shredd
At this stage, shred the material and gather it. Determine how many times to run it through the shredder based on the desired size.
![20230831_114152-18a511c7317.jpg](./20230831_114152-18a511c7317.jpg)
![20230831_114209-18a511c83b3.jpg](./20230831_114209-18a511c83b3.jpg)
![20230831_114253-18a511c8ea3.jpg](./20230831_114253-18a511c8ea3.jpg)
### Step 3: Now it's time for the sheetpress
Place all the chopped plastic into the 1x1 meter (39.37x39.37 inches) mold. Insert the mold into the sheet press to create the plastic sheet.
![20230711_120925-18a512093f5.jpg](./20230711_120925-18a512093f5.jpg)
### Step 4: Time for the CNC
Insert the 1x1 meter (3.28x3.28 feet) sheet, cut into 35x35 centimeter (13.78x13.78 inch) pieces, under the CNC machine to create rounded pieces with a 30 centimeter (11.81 inch) diameter.
![Screenshot_20230901_160800_Gallery-18a51219968.jpg](./Screenshot_20230901_160800_Gallery-18a51219968.jpg)
![20230623_113418-18a5121aac5.jpg](./20230623_113418-18a5121aac5.jpg)
### Step 5: Work is done
Now, all that remains is to drill the plastic discs to be fixed to a metal base, and here is our stool.

As a coastal workshop, it is unsurprising that some of our prototyping focuses on plastics collected during Norfolk beach cleans. Ocean rope is a common discovery for beach cleaners along the 100 miles (160.93 km) of the Norfolk coastline and was one of our earliest experiments in manufacturing from beach findings.

## Steps
### Step 1: Source some ocean rope
An essential step, though perhaps obvious, is worth mentioning nonetheless. Beach clean groups in Norfolk sought a destination for their collected plastics to prevent them from ending up in landfills. We have collaborated with these groups for over a year, during which they gather significant quantities of rope from the Norfolk coastline each month.
If you reside in a coastal area, consider reaching out to organized groups you can locate. They often appreciate the chance to have their plastic collected, as they typically possess a strong affinity and sense of responsibility for marine preservation and ensuring waste is properly managed.
If you are not located near the coast, it may be valuable to connect with beach clean groups elsewhere as a potential source, although sourcing local plastics is generally advisable.

![Beach clean group-18881d0e544.jpg](./Beach_clean_group-18881d0e544.jpg)
### Step 2: Sort and inspect your rope
Sorting and inspecting rope is a crucial step before cleaning. During this process, it is important to identify polypropylene (PP) rope and remove any items such as duct tape or zip ties that may be attached to the rope and won't be eliminated through cleaning.
Identifying polypropylene (PP) ocean rope is relatively straightforward, though not a guaranteed method for accurate material identification. Polypropylene (PP) ropes are distinctly plastic, with characteristic features that typically indicate the correct type. These ropes are not stretchy, often brittle and crunchy to the touch, and commonly a light aqua blue. Ocean rope can also appear black, yellow, or white, though the light blue is generally the easiest to recognize.
Use scissors to remove items like duct tape or zip ties attached to the rope. General dirt will be addressed in the subsequent cleaning step.

![image1-18881d44565.jpeg](./image1-18881d44565.jpeg)
### Step 3: Clean and dry the rope
Cleaning and drying the rope is a straightforward process. A laundry bag, a washing machine, and an airing cupboard are necessary. Use a regular 40-degree centigrade (104 degrees Fahrenheit) wash with an unfragranced detergent.
For drying, utilize common household or workshop areas. Keep the rope in the laundry bag and place it in either an airing cupboard overnight or on a windowsill on a sunny day. Typically, after an afternoon or night in one of these locations, the rope should feel dry. If it remains damp, rearrange the rope so different sections are on top, and leave it for another afternoon or evening.

![image2-18881df7004.jpeg](./image2-18881df7004.jpeg)
### Step 4: Shred your rope
We've discovered that shredding ocean rope is a distinct process compared to shredding hard plastics like DVD cases or soft drink bottle lids. Some ocean ropes obtained from beach cleanups have been found to be as thick as 1.4 inches (36 mm), prompting the use of our larger commercial shredder instead of a smaller one. We recommend checking the thickness of the rope you intend to shred and evaluating the capability of your shredder.
Additionally, it was observed that only a small proportion of the shredded rope fell into the collection bin beneath the blades. Shredding for a longer duration may alter this outcome. In our case, shredding was conducted for a brief period, after which we collected the shredded rope from the bin and carefully removed any remnants from the shredder with gloves after disconnecting the power.

![image2 (1)-18881e8ede2.jpeg](./image2_1-18881e8ede2.jpeg)
### Step 5: Select your mould and machine and apply heat
Once your materials are prepared for fabrication, select your mold and machinery. We utilize a large button mold with ocean rope, heating the mold in a small oven prior to use. Upon using our mold, we observed minor corrosion on the inner surface, which was removed with fine sandpaper.
Equip yourself with personal protective equipment, including a double charcoal-activated face mask and heat-resistant gloves. Ensure your workspace is well-ventilated. Occasionally, a fume extractor is employed; however, for this tutorial, we maximized airflow by opening the workshop's double doors. Preheat your small oven to the required temperature. We set both the oven and the mold to 200 degrees Celsius (390 degrees Fahrenheit).
![image0 (3)-18881f29a14.jpeg](./image0_3-18881f29a14.jpeg)
![image1 (3)-18881f2ac07.jpeg](./image1_3-18881f2ac07.jpeg)
![image2 (2)-18881f2baed.jpeg](./image2_2-18881f2baed.jpeg)
### Step 6: Prepare the Arbour Press for use
Set up your Arbour Press or injection molding machine in a clear, ventilated space on a firm surface and switch it on. We operate our Arbour Press at 265 degrees Celsius (500 degrees Fahrenheit).
Loading your injection molder with shredded rope differs from loading it with shredded hard plastics like DVD cases or soft drink bottle lids. Instead of pouring granules into the hopper, the shredded rope requires more careful handling. While wearing heat-resistant gloves, drop shredded rope into the hopper and use a metal rod to guide it into the chamber. The final step involves using the shaft of the Arbour Press to move it into the body of the press, ready for injection.
When preparing the press for the first injection of the day, allow the Arbour Press to stand for approximately 20 minutes once the material is inside and the temperature stabilizes. Shredded rope may contain more trapped air compared to shredded hard plastics.
![image0 (4)-18881fd0731.jpeg](./image0_4-18881fd0731.jpeg)
![image1 (4)-18881fd2225.jpeg](./image1_4-18881fd2225.jpeg)
![image0 (5)-18881fd3846.jpeg](./image0_5-18881fd3846.jpeg)
### Step 7: Mould your ocean rope buttons
Once the mold reaches the desired temperature and the Arbour Press has been prepared with the ocean rope for insertion, remove the mold from the mini oven. Ensure there is adequate space on the workbench to place the mold once it is filled and sufficient room to maneuver safely around the Arbour Press. Lower the jack, regulate the flow of molten plastic, and position the mold under the nozzle. When ready, connect the mold to the nozzle of the Arbour Press and apply pressure to inject the plastic.
It is crucial to closely monitor both the mold and the pressure from the lever delivering the molten plastic. During this procedure, a small amount of condensation may be observed leaving the mold mid-injection, along with noticeable resistance once the mold is filled.
Relieve some pressure from the lever delivering the molten plastic, lower the mold with the jack, and place the filled mold onto the workbench, ensuring that the Arbour Press can be safely left unattended.
![image0 (6)-18882060f44.jpeg](./image0_6-18882060f44.jpeg)
![image1 (5)-18882062447.jpeg](./image1_5-18882062447.jpeg)
![image2 (3)-18882063776.jpeg](./image2_3-18882063776.jpeg)
### Step 8: Opening the mould and finishing your buttons
During this final stage, we manage our anticipation and remain focused on the process. We assess the condition of the plastic within the mold by observing the visible plastic where the nozzle injected it. Generally, this requires leaving the mold for a few minutes before proceeding to open it.
Wearing gloves to guard against heat and potential injury if the spanner slips, we cautiously remove the bolts securing the mold. Placing the mold on the workbench, we use a tool to carefully pry it open.
Sometimes, the buttons are easily removed. Occasionally, buttons adhere more firmly to the mold as the plastic has cooled and contracted around the mold components. If you need to lever the buttons out of the mold, proceed with great care since scratches on the buttons are difficult to eliminate. We attempt to remove stubborn buttons using any remaining sprue and a small flathead screwdriver. Finish the buttons by trimming off any mold marks.

slug: make-buttons-from-ocean-rope
description: As a coastal workshop, it is unsurprising that some of our prototyping focuses on plastics collected during Norfolk beach cleans. Ocean rope is a common discovery for beach cleaners along the 100 miles (160.93 km) of the Norfolk coastline and was one of our earliest experiments in manufacturing from beach findings.
We select ropes from local finds that exhibit the characteristics of polypropylene ropes, which are not stretchy and are often brittle and crunchy to the touch, commonly in a light aqua blue. We share this video on World Ocean Day because, as a coastal workshop, we feel a particular responsibility for removing plastic from the ocean and transforming it into items that should not return to the sea. Plastic is not the solution for future production, and to address upcoming plastic challenges, significant reductions in production are necessary. Our work focuses on educating about existing plastic while campaigning for stronger policies to reduce production at its source.

## Steps
### Step 1: Source some ocean rope
An essential step, though perhaps obvious, is worth mentioning nonetheless. Beach clean groups in Norfolk sought a destination for their collected plastics to prevent them from ending up in landfills. We have collaborated with these groups for over a year, during which they gather significant quantities of rope from the Norfolk coastline each month.
If you reside in a coastal area, consider reaching out to organized groups you can locate. They often appreciate the chance to have their plastic collected, as they typically possess a strong affinity and sense of responsibility for marine preservation and ensuring waste is properly managed.
If you are not located near the coast, it may be valuable to connect with beach clean groups elsewhere as a potential source, although sourcing local plastics is generally advisable.

### Step 2: Sort and inspect your rope
Sorting and inspecting rope is a crucial step before cleaning. During this process, it is important to identify polypropylene (PP) rope and remove any items such as duct tape or zip ties that may be attached to the rope and won't be eliminated through cleaning.
Identifying polypropylene (PP) ocean rope is relatively straightforward, though not a guaranteed method for accurate material identification. Polypropylene (PP) ropes are distinctly plastic, with characteristic features that typically indicate the correct type. These ropes are not stretchy, often brittle and crunchy to the touch, and commonly a light aqua blue. Ocean rope can also appear black, yellow, or white, though the light blue is generally the easiest to recognize.
Use scissors to remove items like duct tape or zip ties attached to the rope. General dirt will be addressed in the subsequent cleaning step.

<Image src={import('./image1-18881d44565.jpeg')} alt="image1-18881d44565.jpeg" />
### Step 3: Clean and dry the rope
Cleaning and drying the rope is a straightforward process. A laundry bag, a washing machine, and an airing cupboard are necessary. Use a regular 40-degree centigrade (104 degrees Fahrenheit) wash with an unfragranced detergent.
For drying, utilize common household or workshop areas. Keep the rope in the laundry bag and place it in either an airing cupboard overnight or on a windowsill on a sunny day. Typically, after an afternoon or night in one of these locations, the rope should feel dry. If it remains damp, rearrange the rope so different sections are on top, and leave it for another afternoon or evening.

<Image src={import('./image2-18881df7004.jpeg')} alt="image2-18881df7004.jpeg" />
### Step 4: Shred your rope
We've discovered that shredding ocean rope is a distinct process compared to shredding hard plastics like DVD cases or soft drink bottle lids. Some ocean ropes obtained from beach cleanups have been found to be as thick as 1.4 inches (36 mm), prompting the use of our larger commercial shredder instead of a smaller one. We recommend checking the thickness of the rope you intend to shred and evaluating the capability of your shredder.
Additionally, it was observed that only a small proportion of the shredded rope fell into the collection bin beneath the blades. Shredding for a longer duration may alter this outcome. In our case, shredding was conducted for a brief period, after which we collected the shredded rope from the bin and carefully removed any remnants from the shredder with gloves after disconnecting the power.

<Image src={import('./image2_1-18881e8ede2.jpeg')} alt="image2 (1)-18881e8ede2.jpeg" />
### Step 5: Select your mould and machine and apply heat
Once your materials are prepared for fabrication, select your mold and machinery. We utilize a large button mold with ocean rope, heating the mold in a small oven prior to use. Upon using our mold, we observed minor corrosion on the inner surface, which was removed with fine sandpaper.
Equip yourself with personal protective equipment, including a double charcoal-activated face mask and heat-resistant gloves. Ensure your workspace is well-ventilated. Occasionally, a fume extractor is employed; however, for this tutorial, we maximized airflow by opening the workshop's double doors. Preheat your small oven to the required temperature. We set both the oven and the mold to 200 degrees Celsius (390 degrees Fahrenheit).
<Image src={import('./image0_3-18881f29a14.jpeg')} alt="image0 (3)-18881f29a14.jpeg" />
<Image src={import('./image1_3-18881f2ac07.jpeg')} alt="image1 (3)-18881f2ac07.jpeg" />
<Image src={import('./image2_2-18881f2baed.jpeg')} alt="image2 (2)-18881f2baed.jpeg" />
### Step 6: Prepare the Arbour Press for use
Set up your Arbour Press or injection molding machine in a clear, ventilated space on a firm surface and switch it on. We operate our Arbour Press at 265 degrees Celsius (500 degrees Fahrenheit).
Loading your injection molder with shredded rope differs from loading it with shredded hard plastics like DVD cases or soft drink bottle lids. Instead of pouring granules into the hopper, the shredded rope requires more careful handling. While wearing heat-resistant gloves, drop shredded rope into the hopper and use a metal rod to guide it into the chamber. The final step involves using the shaft of the Arbour Press to move it into the body of the press, ready for injection.
When preparing the press for the first injection of the day, allow the Arbour Press to stand for approximately 20 minutes once the material is inside and the temperature stabilizes. Shredded rope may contain more trapped air compared to shredded hard plastics.

<Image src={import('./image1_4-18881fd2225.jpeg')} alt="image1 (4)-18881fd2225.jpeg" />
<Image src={import('./image0_5-18881fd3846.jpeg')} alt="image0 (5)-18881fd3846.jpeg" />
### Step 7: Mould your ocean rope buttons
Once the mold reaches the desired temperature and the Arbour Press has been prepared with the ocean rope for insertion, remove the mold from the mini oven. Ensure there is adequate space on the workbench to place the mold once it is filled and sufficient room to maneuver safely around the Arbour Press. Lower the jack, regulate the flow of molten plastic, and position the mold under the nozzle. When ready, connect the mold to the nozzle of the Arbour Press and apply pressure to inject the plastic.
It is crucial to closely monitor both the mold and the pressure from the lever delivering the molten plastic. During this procedure, a small amount of condensation may be observed leaving the mold mid-injection, along with noticeable resistance once the mold is filled.
Relieve some pressure from the lever delivering the molten plastic, lower the mold with the jack, and place the filled mold onto the workbench, ensuring that the Arbour Press can be safely left unattended.

<Image src={import('./image1_5-18882062447.jpeg')} alt="image1 (5)-18882062447.jpeg" />
<Image src={import('./image2_3-18882063776.jpeg')} alt="image2 (3)-18882063776.jpeg" />
### Step 8: Opening the mould and finishing your buttons
During this final stage, we manage our anticipation and remain focused on the process. We assess the condition of the plastic within the mold by observing the visible plastic where the nozzle injected it. Generally, this requires leaving the mold for a few minutes before proceeding to open it.
Wearing gloves to guard against heat and potential injury if the spanner slips, we cautiously remove the bolts securing the mold. Placing the mold on the workbench, we use a tool to carefully pry it open.
Sometimes, the buttons are easily removed. Occasionally, buttons adhere more firmly to the mold as the plastic has cooled and contracted around the mold components. If you need to lever the buttons out of the mold, proceed with great care since scratches on the buttons are difficult to eliminate. We attempt to remove stubborn buttons using any remaining sprue and a small flathead screwdriver. Finish the buttons by trimming off any mold marks.

### Step 1: Ready set go
Download the attached .dxf file and select a sheet with a thickness of 5 mm (0.2 inches). Proceed to cut using a CNC Router. For first-time users, it is advisable to utilize a 1-edged mill with a 4 mm (0.16 inches) diameter for cutting. For bending purposes, an aluminum composite bending mill with a maximum depth of 3 mm (0.12 inches) is ideal.

![Mesa de trabajo 5-100.jpg](./Mesa_de_trabajo_5-100.jpg)
### Step 2: Folded
Release all pieces of the sheet and fold them using a heat gun. Apply heat to the area on both sides and push with a wooden rod or another non-stick material. Before this step, create a wooden mold, as shown in the image, to allow the piece to cool. Make two cuts to accommodate the width of the key hanger.

![Mesa de trabajo 10-100.jpg](./Mesa_de_trabajo_10-100.jpg)
### Step 3: Placement
Make two holes in the wall and use the necessary anchors based on the wall material. First, attach the part with the perforations to the wall. Then, embed the second part.
To place the horizontal piece, thread it from one side, through one of the inserts.
The horizontal piece that holds the keys has a small feature that prevents it from moving. Enjoy the key hanger.

![Mesa de trabajo 11-100.jpg](./Mesa_de_trabajo_11-100.jpg)
### Step 4: Hang what you like
The key hanger is installed. Now, creativity can guide us to hang various items. Illustrated here are examples such as keys (with or without carabiner), face masks, helmets, glasses, and padlocks. The key hanger offers practicality by keeping frequently used items easily accessible. Share your own uses with us.

# Polygonal mould for sheet press
![Polygonal mould for sheet press](Screenshot_3-18551b60d58-187bbbca774.png)
Plastic sheets made with a sheet press do not need to be square.
This tutorial demonstrates how to create an octagonal mold for crafting octagonal plastic sheets. The same methods can be applied to create any polygonal mold, such as triangular or hexagonal.
For any questions or suggestions regarding the mold, please feel free to contact us.
User Location: Sukawati, Indonesia
## Steps
### Step 1: Gather tools and material
**Tools:**
- Sheet press set
- Angle grinder
- Welding tools and materials
- Jigsaw
- Sander (for product finishing)
- Safety gear: welding helmet, safety glasses, mask
- Marker
- Ruler
Computer with drafting/drawing software
**Materials:**
- Steel for mold: 0.8x0.8 inches (2x2 cm) galvanized steel (standard size = 19.7 feet/6 m)
- Clean, sorted plastic of chosen type
![Screenshot_20221228_035519-18557c81e43 (1)-187bbb8d51c.png](./Screenshot_20221228_035519-18557c81e43_1-187bbb8d51c.png)

### Step 2: Draw
Draw the polygon using any drafting software. This provides precise information on the dimensions of each side. Refer to our drawing in the provided link for guidance.
Measure your sheet press workspace.
Offset inward by 5 cm (approximately 2 inches) for the space needed around the mold.
Draw the polygon according to the capacity of your sheet press machine.
Offset inward by 2 cm (approximately 0.8 inches) for the thickness of the galvanized steel.
Obtain the mold dimensions from your drawing. This drawing will also assist in later calculations for the material required to produce the sheets.
![octagonal sheets-185529f10cc-187bbb95bc1.png](./octagonal_sheets-185529f10cc-187bbb95bc1.png)
### Step 3: Cut
After determining the measurements, cut the 0.8-inch (20mm) hollow galvanized steel to size using an angle grinder.
Draw measurements with an erasable marker for precision.
Cut using an angle grinder.
With a whiteboard marker, draw a full-scale template of your sheets to ensure the angles and dimensions align, adjusting as necessary.

### Step 4: Weld
Create a 1:1 template of your sheets using a whiteboard marker to ensure that the angles and dimensions align correctly, and make adjustments as necessary.
Weld all the sides to join the ends and form your polygonal sheets.

![Screenshot (97)-1854d36eb66-187bbba884b.png](./Screenshot_97-1854d36eb66-187bbba884b.png)
### Step 5: Finishing
Grind the excess welding materials with an angle grinder.
This step ensures that the mold is perfectly flat against the sheets. Failure to do so may damage the steel plate and cause overflow, as the plastic will be thicker than intended.

![IMG_5700-18557c53ec1-187bbbb390e.jpg](./IMG_5700-18557c53ec1-187bbbb390e.jpg)
### Step 6: Make your polygonal sheet
It's time to create your polygonal sheet.
Use the area of your polygon from the drawing to determine the amount of plastic needed for the sheet.

<Image src={import('./Screenshot_3-18551b60d58-187bbbca774.png')} alt="Polygonal mould for sheet press" />
Plastic sheets made with a sheet press do not need to be square.
This tutorial demonstrates how to create an octagonal mold for crafting octagonal plastic sheets. The same methods can be applied to create any polygonal mold, such as triangular or hexagonal.
For any questions or suggestions regarding the mold, please feel free to contact us.
User Location: Sukawati, Indonesia
## Steps
### Step 1: Gather tools and material
**Tools:**
- Sheet press set
- Angle grinder
- Welding tools and materials
- Jigsaw
- Sander (for product finishing)
- Safety gear: welding helmet, safety glasses, mask
- Marker
- Ruler
Computer with drafting/drawing software
**Materials:**
- Steel for mold: 0.8x0.8 inches (2x2 cm) galvanized steel (standard size = 19.7 feet/6 m)
- Clean, sorted plastic of chosen type
<Image src={import('./Screenshot_20221228_035519-18557c81e43_1-187bbb8d51c.png')} alt="Screenshot_20221228_035519-18557c81e43 (1)-187bbb8d51c.png" />
<Image src={import('./IMG_5704-18557ab30d8_1-187bbb8fc4b.jpg')} alt="IMG_5704-18557ab30d8 (1)-187bbb8fc4b.jpg" />
### Step 2: Draw
Draw the polygon using any drafting software. This provides precise information on the dimensions of each side. Refer to our drawing in the provided link for guidance.
Measure your sheet press workspace.
Offset inward by 5 cm (approximately 2 inches) for the space needed around the mold.
Draw the polygon according to the capacity of your sheet press machine.
Offset inward by 2 cm (approximately 0.8 inches) for the thickness of the galvanized steel.
Obtain the mold dimensions from your drawing. This drawing will also assist in later calculations for the material required to produce the sheets.
<Image src={import('./octagonal_sheets-185529f10cc-187bbb95bc1.png')} alt="octagonal sheets-185529f10cc-187bbb95bc1.png" />
### Step 3: Cut
After determining the measurements, cut the 0.8-inch (20mm) hollow galvanized steel to size using an angle grinder.
Draw measurements with an erasable marker for precision.
Cut using an angle grinder.
With a whiteboard marker, draw a full-scale template of your sheets to ensure the angles and dimensions align, adjusting as necessary.

# Surf Fins Mould
![Surf Fins Mould](IMG_20201204_121653-18b4233f5d2.jpg)
Precios Plastic Valencia will guide you through a straightforward method for creating a mold to produce surf fins.
The process includes preparing the 2D/3D model for laser cutting, injecting the plastic materials, and finishing the product.
Contents of this folder include:
- 3D CAD files (.step and .f3d)
- Laser cut files (.dxf)
- Blueprints (.pdf)
User Location: Valencia, Spain
## Steps
### Step 1: Design mould
As a preliminary step, you must design the appropriate dimensions for your fin to meet surfboard specifications.
The crucial dimensions are where the fin connects with the surfboard, which may vary. Ensure you check its width, height, and thickness (derived from the stainless steel sheet's size, specifically 1/4 inch (6 mm)). For the top and bottom pieces, we recommend a thickness of 3/8 inch (10 mm).
You can download the .DXF and .F3D files and adjust these measurements as necessary.
Once you have verified the sizes, export each drawing (three in total) in .DXF format. These files should be laser cut in stainless steel by an industrial laser cutting service, which typically offers reasonable rates.
Instruct the company to create an M8 thread in the center of the top piece. If this service is unavailable, you may alternatively weld an M8 nut in place. This component is essential for attaching the injection nozzle to the mold; consult your machine for compatibility.

![Design mould2-18b4246db0b.png](./Design_mould2-18b4246db0b.png)
![Design mould3-18b424ae07e.png](./Design_mould3-18b424ae07e.png)
### Step 2: Injection!
Once you have your laser-cut mold, it is time to fill it with plastic waste.
You will need seven M8x40 screws (or longer) to secure the three mold layers. Utilize an M8 nut to connect the mold to the injection machine and experiment with different injection point positions. If your injection machine lacks threading, you can use the hole/injection point without a thread.
We suggest using PP, as PE tends to break easily.

![IMG_20201204_121653-18b4272db92.jpg](./IMG_20201204_121653-18b4272db92.jpg)
### Step 3: Post-processing
As the mold used is laser-cut, its edges are straight and may present challenges for surfing. To address this, the edges must be sanded, introducing an opportunity for craftsmanship.
To maintain the center line and avoid distorting the vertical alignment, draw a line along the edge and create an offset perimeter on both faces, ensuring minimal material removal. A rotary tool should be employed, with appropriate safety gear such as safety glasses and a mask.
If this step were to be omitted, a CNC mold would be required. Though more costly, it would result in an injection-ready object with a hydrodynamic shape, eliminating the need for sanding.

### Step 4: Finishing
You may utilize an electric sanding machine to significantly reduce the time spent on sanding. Begin with a coarse grit sandpaper (grain 120) to remove substantial material. Proceed with a medium grit (grain 320), and complete the process with a fine grit (grain 800). The grit numbers are provided as guidance; experimentation with various grits is encouraged. Polishing can be achieved with an extremely fine grit (grain 3000 or higher).
To enhance the surface finish, apply a brief amount of heat at the conclusion of the sanding process.

Precios Plastic Valencia will guide you through a straightforward method for creating a mold to produce surf fins.
The process includes preparing the 2D/3D model for laser cutting, injecting the plastic materials, and finishing the product.
Contents of this folder include:
- 3D CAD files (.step and .f3d)
- Laser cut files (.dxf)
- Blueprints (.pdf)
User Location: Valencia, Spain
## Steps
### Step 1: Design mould
As a preliminary step, you must design the appropriate dimensions for your fin to meet surfboard specifications.
The crucial dimensions are where the fin connects with the surfboard, which may vary. Ensure you check its width, height, and thickness (derived from the stainless steel sheet's size, specifically 1/4 inch (6 mm)). For the top and bottom pieces, we recommend a thickness of 3/8 inch (10 mm).
You can download the .DXF and .F3D files and adjust these measurements as necessary.
Once you have verified the sizes, export each drawing (three in total) in .DXF format. These files should be laser cut in stainless steel by an industrial laser cutting service, which typically offers reasonable rates.
Instruct the company to create an M8 thread in the center of the top piece. If this service is unavailable, you may alternatively weld an M8 nut in place. This component is essential for attaching the injection nozzle to the mold; consult your machine for compatibility.

<Image src={import('./Design_mould3-18b424ae07e.png')} alt="Design mould3-18b424ae07e.png" />
### Step 2: Injection!
Once you have your laser-cut mold, it is time to fill it with plastic waste.
You will need seven M8x40 screws (or longer) to secure the three mold layers. Utilize an M8 nut to connect the mold to the injection machine and experiment with different injection point positions. If your injection machine lacks threading, you can use the hole/injection point without a thread.
We suggest using PP, as PE tends to break easily.

### Step 3: Post-processing
As the mold used is laser-cut, its edges are straight and may present challenges for surfing. To address this, the edges must be sanded, introducing an opportunity for craftsmanship.
To maintain the center line and avoid distorting the vertical alignment, draw a line along the edge and create an offset perimeter on both faces, ensuring minimal material removal. A rotary tool should be employed, with appropriate safety gear such as safety glasses and a mask.
If this step were to be omitted, a CNC mold would be required. Though more costly, it would result in an injection-ready object with a hydrodynamic shape, eliminating the need for sanding.
