Web9.1 Introduction. Biodegradable polymers are viable alternatives to nondegradable plastics for the abatement of environmental pollution. IUPAC defines biodegradable polymers as “polymer susceptible to degradation by biological activity, with the degradation accompanied by a lowering of its molar mass” [1]. Biodegradation is the breakdown of organic matter by microorganisms, such as bacteria and fungi. It is generally assumed to be a natural process, which differentiates it from composting. Composting is a human-driven process in which biodegradation occurs under a specific set of circumstances. The process of biodegradation is threefold: first an object undergoes biodeteri…
