Why should biodegradable and non biodegradable wastes be discarded in two separate dustbins?

Biodegradable waste is a type of waste, typically originating from plant or animal sources, which may be degraded by other living organisms. Wastes that cannot be broken down by other living organisms are called non-biodegradable.

The basic difference between biodegradable and non-biodegradable is that biodegradable items decompose or break down naturally. Large volumes of non-biodegradable waste take up excess waste and are potentially damaging to the environment.

Biodegradable and non-biodegradable wastes should be discarded in two different dustbins so that they can be collected separately. Waste can be segregated at the source itself which in turn allows effective treatment and disposal. The biodegradable waste can be decomposed in a natural manner by the process of composting. Non-biodegradable wastes can be sent for recycling. If the two wastes are collected in a single bin, they would mix and may form toxic compounds which can cause pollution.
