These biodegradable wastes are animal or plant matter that breaks down naturally with exposure to microorganisms, heat, and oxygen. There are other ways also for their decomposition:

a) Collect all the material and burn it in a pit.

b) React it with some strong acid. But both these ways are not good for nature.

c) Recycling them into a usable material which is called composting. It is done is a sealed container (no presence of air). It will get converted into humus-like material which is a good fertilizer for plants. This step is eco-friendly.
