What are Compostable Plastics?
Many people confuse biodegradable with compostable. Biodegradable broadly means that an object is biologically broken down, while compostable typically specifies that such a process will result in compost or humus which can sustain plant growth.
Compostable plastics degrade due to a biological process in which they are converted into carbon dioxide, water and mineral salts, disintegrating within 180 days without producing any toxic material.
