Solution
Biodegradable waste and non-biodegradable waste are the two types of waste. With the help of microbes, biodegradable waste is easily converted into simpler forms and used as manure. Non-biodegradable trash, on the other hand, cannot be transformed into simpler forms but can be recycled. Hence, they must be kept separate.
