Whereas the materials that are inorganic and hence cannot be decomposed by any means are termed as non-biodegradable wastes. They persist in the environment for a long time thereby polluting the environment. They cannot even be burnt as their burning releases a lot of hazardous gases in the environment causing air pollution. This kind of materials includes plastic, metals, glass etc.
