18 Jul 2023 --- Research from the Chinese University of Hong Kong has created an edible, biodegradable and transparent material using soy protein isolate to replace plastic in food packaging. The scientists point to the “pervasive presence” of plastic packaging leading to significant environmental contamination due to excessive reliance on petrochemicals and the inherent non-biodegradability of the material. “The widespread use of petroleum-based plastics as food packaging has created significant pollution to our ecosystem,” write the researchers.
