Bio-based Plastic

Our first course of the autumn semester was on sustainability. One of the many things we were taught was the insight into how bad plastic derived from crude oil is and in how many ways it pollutes our planet. This is when we were taught how to make bio-based plastics.

Carrageenan algae powder, glycerine and recipe.

Because of the pandemic, my school sent the ingredients home to me. It felt so special to get the package in the mail.

Carrageenan and water set over night.
My collection of additional ingredients. Fur tree needles, red onion peel, a black tea bag, used coffee grounds, and a banana peel.
And toilet paper cut up in small pieces. Because I wanted to attempt to make my own super absorbent.

Cutting up banana peels and weighing it to know what I am doing, sort of.

Cooked, mixed, strained and drying banana peel and fur tree needles.
Carrageenan and water gel added to the sauce pan. As it heats up it begin to melt.

Banana peel mix to the left, toilet paper mix to the right. The trays (that I have made as well) have a pattern to them, which shines through the mixture.
