Compostable means that a product can break down into carbon dioxide, water, inorganic compounds and biomass in small pieces in about 90 days. This rate is similar to items you might see in a backyard compost, such as leaves and paper.
Compost works because millions of tiny microbes consume the waste and transform the organic material into compost. Compost has many beneficial uses including fertilizing and improving soil health—plus, it doesn’t leave toxic residue behind because it’s already organic.
