Which of the following are Biodegradable wastes?
Rotten Tomatoes
If a waste is biodegradable, microbes act on it and degrade the material. This makes it easier to get rid of or re-use it for other purposes, example: manure.
Plastic does not undergo this process quickly. Plastic will take more than thousands of years to degrade by weathering.
So, plastic is a non-biodegradable waste.
