Biodegradable plastics can be divided into two types: fully biodegradable plastics and destructive biodegradable plastics. Destructive biodegradable plastics currently mainly include starch modified (or filled) polyethylene PE, polypropylene PP, polyvinyl chloride PVC, polystyrene PS and the like.

Completely biodegradable plastics are mainly made from natural polymers (such as starch, cellulose, chitin) or agricultural by-products by microbial fermentation or synthesis of biodegradable polymers, such as thermoplastic starch plastics, aliphatic polyesters, polylactic acid. Starch/polyvinyl alcohol, etc. are all such plastics.

Biodegradable plastics based on natural substances such as starch currently include the following products: polylactic acid (PLA), polyhydroxyalkanoate (PHA), starch plastics, bioengineering plastics, bio-generic plastics (polyolefins and polychlorinated chlorine). 

Next, I recommend two cutlery made of biodegradable plastic for Dajia. I hope you like it.
