The compostability of bioplastics refers to the breakdown of bioplastics into compost (biomass) that enriches soil.
This means that anything that is compostable is also biodegradable. But if something is biodegradable, it is not necessarily compostable, too.
Compostability is regulated by ASTM International. They set the standard for compostability to mean that in an industrial composting facility, under aerobic conditions, compostable plastics will disintegrate through the aid of microorganisms within 12 weeks and biodegrade within 180 days into carbon dioxide, water, minerals, and biomass (compost). The temperature is maintained at approximately 120-170℉. The moisture level is at 50-60%.
