Mix all the ingredients together in a cooking pot: Gelatin 13 grams, vegetable glycerol 6 grams, water 250 militres and used yerba mate te leaves).
On the stove or using a burner, heat the mixture until it boils.
When you take the mixture away, let it cool down until it is only warm in temperature and then pour on a plastic or metal surface. Ensure that the surface has edges and that it is also flat/level.
Let your biomaterial dry. You can use a fan to dry the material and speed up the process if you want to produce the material faster.
If you want to prepare a more flexible plastic, you have to use a food processor to grind the used yerba mate.
