Why is segregation of waste is important in waste management

Segregation of waste before disposal is important as it makes the recycling easy. Because we know that each type of waste have different mechanism to recycle. Waste segregation involves separating waste in Biodegradable and Non-biodegradable.
Biodegradable waste includes organic waste, e.g. kitchen waste, vegetables, fruits, flowers, leaves from the garden, and paper. Non-biodegradable waste includes some recyclable and non-recyclable waste. Recyclable waste are– plastics, paper, glass, metal, etc.which are non-biodegradable and they follow various mechanism for recycling.
So the segregation is important.
