Degradable plastics can also be divided into bio-based degradable plastics and petroleum-based degradable plastics.
The former is plastics produced from biomass, mainly including PLA (polylactic acid), PHA (polyhydroxyalkanoate), PGA (polyglutamic acid), etc. The latter is made of fossil energy as raw materials, mainly including PBSA (polybutylene adipate), PBAT (polybutylene adipate/terephthalate), PCL (polycaprolactone Ester) etc.
