Biodegradable waste is defined as a material that degrades naturally, such as by the action of microorganisms.
Vegetable and fruit peels, as well as wood, are examples.
Non-biodegradable wastes are those that are not easily degraded by natural processes such as bacterial action.
Plastics and glass are two examples.
Final answer:
The wastes which get decomposed naturally are biodegradable wastes, while the wastes which do not follow a natural process of decomposition are non biodegradable wastes.
