Detailed explanation-1: -“Biodegradable” refers to the ability of things to get disintegrated (decomposed) by the action of micro-organisms such as bacteria or fungi biological (with or without oxygen) while getting assimilated into the natural environment. There’s no ecological harm during the process.
Detailed explanation-2: -Just because something can biodegrade naturally, doesn’t mean it’s better for the environment. When biodegradable products are sent to landfill, including biodegradable plastics and items like grass cuttings or newspapers, they break down into two greenhouse gases: methane and carbon dioxide.
Detailed explanation-3: -Compostable means that a product is capable of breaking down into natural elements in a compost environment. Because it’s broken down into its natural elements it causes no harm to the environment. The breakdown process usually takes about 90 days.
Detailed explanation-4: -Biodegradable wastes are such waste materials which are and can be degraded by natural factors like microbes (e.g. bacteria, fungi and few more), abiotic elements like temperature, UV, oxygen, etc. Some examples of such wastes are food materials, kitchen wastes, and other natural wastes.
Detailed explanation-5: -: capable of being broken down especially into innocuous products by the action of living things (such as microorganisms)
