Photobiodegradable Plastics via PPDvSOP improvement

BACKGROUND At first plastics were welcome as blessings. Specifically, their durability, high strength per weight and low cost have made them the ideal packaging materials. However, the last seven decades have proved, those same attributes combined with improper waste management, led to a plastic pollution problem. An estimated 6300 million metric tons...
