BIO-DEGRADATION
Biodegradation is the failure of organic matter by microorganisms, such as bacteria and fungi. The process of biodegradation can be divided into three stages: bio deterioration, bio fragmentation, and assimilation. Bio deterioration is sometimes described as a surface-level degradation that modifies the mechanical, physical and chemical properties of the material. This stage occurs whenever the material is revealed to abiotic factors in the outdoor environment and allows for further degradation by making the material's structure weak. Some abiotic element that influence these initial changes are compression i.e. ,mechanical, light, temperature and chemicals in the environment.
