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.
