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.
The concept of structure biodegradability relationships (SBR) has been applied to explain variability in persistence among organic chemicals in the environment. Early attempts generally consisted of examining the degradation of a homologous series of structurally related compounds under identical conditions with a complex "universal" inoculum ...
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.
Bio-based materials are often biodegradable, but this is not always the case.. By definition, biodegradable materials are formed or organic compounds which can thus be broken down by living organisms, such as bacteria, fungi, or water molds, and reabsorbed by the natural environment.
These experiments must be done for various plastics, as the differences in the properties of the plastics will affect the binding ability of the microbial strain. To determine whether the strain of microorganism is degrading the plastic, measurements of the amount of carbon dioxide present is typically used since carbon dioxide is a product of ...
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.
