ABSTRACT

Over the last few years, the fabrication of plastics from renewable resources has become a new economic challenge. Biopolymers, the best known of which is cellulose, are polymers derived from living organisms or synthetized from renewable resources. These polymers have expanded significantly due to their biological origin and mostly to their biodegradable nature. Their uses as substitutes or even mixed to other polymers synthetized from hydrocarbons thus offer interesting applications.

 INTRODUCTION

In recent years, the manufacture of plastics from renewable resources has emerged as a new economic challenge. This is linked to the growing awareness of the impact of plastic materials, whose polluting nature due to poor recycling poses a risk to our planet. Polymer chemistry was born of the knowledge of a common biopolymer: cellulose, better known as wood. In fact, cellulose belongs to the polysaccharide family, which is one of the biopolymer families. Biopolymers are polymers derived exclusively from living organisms, or from polymers synthesized from renewable resources. Over the past few years, these polymers have experienced a real boom, thanks to their biological origins and, above all, their biodegradable nature. Their use as substitutes for, or even blends with, other polymers synthesized from hydrocarbons offers interesting applications. Indeed, in a world where recyclable or biodegradable materials are becoming increasingly important, biopolymers are being put to ever greater use.
