TLDR
Data is summarized on their use, biodegradability, commercial reliability and production from renewable resources from a variety of sources including microbial fermentations and chemically modified natural products.Abstract:
Plastic waste disposal is a huge ecotechnological problem and one of the approaches to solving this problem is the development of biodegradable plastics This review summarizes data on their use, biodegradability, commercial reliability and production from renewable resources Some commercially successful biodegradable plastics are based on chemical synthesis (ie polyglycolic acid, polylactic acid, polycaprolactone, and polyvinyl alcohol) Others are products of microbial fermentations (ie polyesters and neutral polysaccharides) or are prepared from chemically modified natural products (eg, starch, cellulose, chitin or soy protein)read more
