Biodegradability: the conversion of >90% of the original material into CO 2, water and minerals by biological processes within 6 months. Disintegrability : at least 90% of the original mass should be decomposed into particles that are able to pass through a 2x2 mm sieve.
Biodegradable waste includes any organic matter in waste which can be broken down into carbon dioxide, water, methane, compost, humus, and simple organic molecules by micro-organisms and other living things by composting, aerobic digestion, anaerobic digestion or similar processes.
In typical parlance, the word biodegradable is distinct in meaning from compostable.While biodegradable simply means an object is capable of being decomposed by bacteria or other living organisms, "compostable" in the plastic industry is defined as able to decompose in aerobic environments that are maintained under specific controlled temperature and humidity conditions.
In this regard, biodegradability does not support circularity unless biodegradable materials are recovered and processed by a system that can either recapture or upgrade their value. Ensuring a proper infrastructure for these materials to remain in the material management system, for instance through industrial composting or anaerobic digestion ...
One of the challenges for the design and use of biodegradable plastics is that biodegradability is a "system property". That is, whether a particular plastic item will biodegrade depends not only on the intrinsic properties of the item, but also on the conditions in the environment in which it ends up.
Biodegradable polymers are a special class of polymer that breaks down after its intended purpose by bacterial decomposition process to result in natural byproducts such as gases (CO 2, N 2), water, biomass, and inorganic salts.

It does not invoke a toxic response. It is metabolized in the body after fulfilling its purpose. It is easily processable in the final product form with an acceptable shelf life and easily sterilized .
