What makes some items biodegradeable?

    Biodegradable matter is generally organic material such as plant and animal matter and other substances originating from living organisms, or artificial materials that are similar enough to plant and animal matter to be put to use by microorganisms.

    Hydro-biodegradable plastics (HBP) and oxo-biodegradable plastics (OBP)are two main types of biodegradable plastics in the market. Both oxo- and hydro-biodegradable plastics will first undergo chemical degradation by oxidation and hydrolysis respectively. This leads to a drastic reduction in their molecular weights and their physical disintegration. These fragmens which are smaller and has lower molecular weight are then open for biodegradation.
