-
Do not degrade
-
Degrades efficiently
-
Degrades very slowly

- Non-Biodegradable wastes are those that cannot break down or degrade for many years. These are waste that cannot change into manure and they pile up causing pollution. Burning these fuels causes more pollution in the environment. The non-biodegradable wastes become useful when they can be recycled.

Waste that cannot be broken down by other living organisms is called as non-biodegradable. Non-biodegradable substances affect the environment. They may enter the food chain and harm the organisms in the higher trophic levels (by biomagnification), e.g., pesticides, like DDT, non-biodegradable substances like radioactive wastes, lead, mercury etc., affect the health of all living organisms.
