Single Use Plastic – Spider Silk Polymer Film made from Plant Proteins Described

A May 17, 2021 UK University of Cambridge announcement https://www.ch.cam.ac.uk/news/research-breakthrough-provides-alternative-single-use-plastics reports the creation of a “… polymer film from plant proteins … [that] is as strong as the most common plastics in use today … It is home compostable and will degrade naturally in a marine environment and in fresh water … The researchers have shown that they can successfully replicate the structures found on spider silk … The researchers chose soy protein isolate (SPI) as their test plant protein … The material has a performance equivalent to high performance engineering plastics such as low-density polyethylene. Its strength lies in the regular arrangement of the polypeptide chains …” – The research was published June 10, 2021 in Nature Communications https://www.nature.com/articles/s41467-021-23813-6 #PlasticWaste #SingleUsePlastic @Cambridge_Uni
