With 8 billion tons of plastic waste entering our oceans, a move towards recycling and reuse has been implemented. Alongside these efforts, a movement to create biodegradable plastics is also underway. Commercially, if a plastic contains 20% renewable material it is considered to be “bio-based.” This 20% is usually made of shrimp shells, wood, coconut, wheat, corn or other renewable materials. This also means the remaining 80% can be made from traditional fossil fuel-based plastic polymers. These fuel-based plastics leach and create a concentrated source of estrogen disruptors (Link) that negatively impact biodiversity and human health. Join us as we explore more sustainable and less toxic polymers in an effort to protect ecosystem health and reduce landfill waste. In this lab, we use a very simple proof of concept approach to creating biopolymers from household items such as starch, milk, and sugar and examine variables such as temperature, concentration, and time in their synthesis.
