Biodegradable Plastics

The properties of plastics are determined by the polymers that constitute the unit. Based on this, plastics can be modified into biodegradable products by varying the constituents synthetically. Their chemical structures vary due to the substituting polyesters in the polymer chain. Let’s study about the chemical differences and structure of green plastics; PHA and PLA. Amylose and Amylopectin are the major polymer components of starch. In the link structure, all identical chain points are connected to –CH2OH group. The oxygen in the ring structure chain facilitates degradation when reacted with water. Any hybrid variety can be produced with two components: renewable natural polymer (starch) and petroleum based synthetic polymer (PCL). • Polylactide (PLA) is a bioplastic basically made from starch,…
