Coaster from coffee waste
This exponential coffee craze has led us to a staggering amount of coffee ground that is just wasted. Here is how you can turn that waste into something more valuable with all the simple ingredients and also appliances used.
User Location: Cikarang, Indonesia
Steps
Step 1: Prepare all the ingredients
Prep all the ingredients now as the cooking process occurs quickly. For this particular brick and mold, I use a mixture of 7 tbsp of tapioca starch, 10 tbsp of coffee ground waste, 1 tbsp of vinegar, and 180 ml of water. However, different blends can create different brick characteristics, so try various ratios for different results. The tapioca starch acts as a binding agent while the coffee ground is the “filler” and the dye. Mix all the ingredients well until there are no lumps in the mixture.
Step 2: Cooking process
This process is fast so get into high gear! Cook the mixture on low heat while constantly stirring it until it thickens. Once the mixture has thickened, turn off the heat, and the cooking process is done.
Step 3: Mold your mixture
Transfer the thickened mixture to your mold. You can use wax or line the mold using wax paper to help release the mold when it has dried out.
Step 4: Waiting Game
Let the mixture dry into a solid piece at room temperature. This process can take from 2 up to 4 days depending on the size of the mold and the thickness of the brick. After it already forms into a solid brick, pull the brick out of the mold and dry it further until the brick is as hard as desired. You can also speed up this process by using an oven to quickly dry the brick.
