- They can also be diposed of through waste treatment plants or converted into an agricultural resource of manure and compost.
- They are the wastes which cannot be broken down by decomposers because they do not have enzymes for the same.
- Most of the nonbiodegrable wastes are human made, e.g., plastic, crockery, metallic cans, glass articles, polythene bgas, synthene fibres, silver foil, many pesticides (e.g., BHC, DDT).
