Why should biodegradable and non-biodegradable wastes be discarded in two separate dust bins?

Biodegradable and non-biodegradable wastes should be discarded in two separate bins as this helps in effective treatment and disposal of these wastes. Biodegradable wastes can be easily disposed of by the natural way of composting while non-biodegradable wastes can be sent for safe disposal or recycling. This helps in protecting the environment from pollution.
