A compostable product is capable of breaking down into natural elements of compost. The biological process of degradation during composting should yield CO2, water, inorganic compounds, and biomass at a rate consistent with other compostable materials and leave no toxic residue.
Compostable and biodegradable can often be confused. The difference is that compostable materials go one step beyond biodegradable. While biodegradable materials are neutral to the environment, compostable materials are an added benefit to the environment. Compostable materials release a health body of nutrients into the soil, supporting the development of the environment.
