Plastics have long been condemned by environmentalists because they are not bio-degradable, but the discovery of 'biopolymers' has changed all that. Biopolymers replace the low-cost, petroleum-based plastics with materials made from crops such as corn and potatoes or from solid waste generated by the food processing industry.
