Biodegradable Polymers: Challenges and Strategies

Abstract

Synthetic polymers have displaced metals, glasses, ceramics, and wood in many products, especially in the area of packaging. Poly(ethylene), poly(styrene), poly(viny1 chloride), and poly(propylene), in a variety of forms such as films, flexible pouches, and rigid containers, have revolutionized the packaging industry. However, these materials, once discarded, persist in the environment without being degraded, thus giving rise to a multitude of ecological and environmental concerns.
