How does composting work?
Certified compostable bioplastics completely degrade within 180 days. They do not create any toxic byproducts as they compost. Industrial composting facilities carefully regulate temperature and humidity levels to encourage quick degradation. In an ideal environment, PLA loses molecular weight and becomes a food source for naturally present microorganisms.
If you put compostable material in the trash can or recycling bin it will not compost. In an anaerobic environment such as a landfill, compostables do not have the oxygen they need to biodegrade. Compostable containers cannot currently be recycled.
