Plastics that decompose in the nature by the action of microorganisms are generally referred as biodegradable plastics. These plastics are divided into different categories such as bio-based and petro-based biodegradable plastics. The most common process employed in the manufacturing of biodegradable plastics includes fermentation of sugar or canola oil to produce polylactic acid (PLA) or polyhydroxyalkanoates (PHA), which in turn is converted into biodegradable plastics.
