Plastics are synthetic polymers and derive their raw materials from the byproducts of petroleum. When the raw material monomers are combined together [polymerization], they form substances which are non-biodegradable.
1. Biodegradable are the one which gets decomposed within very short period. While non biodegradable take longer time.
2. Biodegradable wastes are non pollutants while non biodegradable are pollutants.
3. Biodegradable ones are degraded by living organisms while non biodegradable have no part with living organisms.
4. Biodegradable wastes can be disposed easily but non ones cannot.
5. Biodegradable are organic ones whereas the non ones are artificial mostly polymers
6. Biodegradable can act as soil manures while non ones cannot.
biodegradable example - fruits, vegetables, plants, animals, etc..
non biodegradable example - plastics, glasses, etc
