Biodegradable film from fermented soymeal

Researchers at the University of Alberta in Canada utilized an inexpensive soymeal for biobased and biodegradable film development. The carbohydrates were destructurized by natural fermentation, yeast fermentation or simultaneous enzyme saccharification and fermentation. The treated soymeals were then plasticized with glycerol, and blended with poly(butylene adipate-co-terephthalate) (PBAT).
They found that fermentation of soymeal is an effective and inexpensive method of destructurizing unnecessary carbohydrates for plastic production without the use of any toxic chemicals or extraction techniques. An article about the research is published in ACS Sustainable Chemistry & Engineering.
