How Compostable Plastics are made?

Except BIOTEC BAGS® all other compostable Plastics presently in the world are made from the biopolymers. They can be called as biobased / biosourced / agrobased pCymers. Starch is the reserve carbohydrate of plants. By modification of its properties chemically, they make biopolymer. Different kinds of Compostable Plastics are made from different raw-materials such as Polyhdroxy Fatty Acids (PHA – Polyhydroxyalknoaates & The two members of the PHA families are Polyhydroxyhexanoates (PHBHs) and Polyhydroxyvalerate (PHV)), Polyactic acid (PLA), Polycaprolactone (PLC), Polybutylene succinate (PBS) and Enzyme based/enzyme treated plastics.
