Scientists turn plastic bottles and corn waste into protein-rich cookies

Researchers at Southern Illinois University Carbondale are developing protein-rich cookies made using plastic waste and agricultural waste. Called µBites, the cookies use PET plastic from bottles and discarded corn stalks and leaves. Programmed yeasts convert processed waste into proteins, fats, acids and flavouring molecules. The NASA-linked project is aimed at developing food for resource-limited environments, including future deep-space missions.
