The problems caused by the non-biodegradable wastes that we generate are:
(i) The non-biodegradable wastes cannot be decomposed by microorganisms like bacteria. So, the volume of these wastes will not decrease creating the problem of their disposal.
(ii) They have to be dumped on land. Hence, the land becomes unfit for other purposes.

(iii) Heavy metals present in industrial waste like copper, lead, nickel, mercury remain in the soil indefinitely. Slowly, they pass into vegetation and crops and thus harm both humans and animals.
(iv) Pesticides and other toxins pollute underground water, surface water and soil. The chemicals enter food chain thereby harming animals and humans, and the soil may become acidic or alkaline.
(v) In the process of removing recyclable materials from solid wastes, the rag-pickers are exposed to many diseases and toxins
