What Is a Compostable Bag?
Compostable bags are eco-friendly bags that can be decomposed by microorganisms under certain conditions (industrial composting or home composting) and converted into water, carbon dioxide and biomass within 90-180 days. They are generally made of plant-based materials (corn starch, polylactic acid or other biodegradable resins) and are environmentally friendly and pollution-free.
