چکیده
In the recent years, bio-based and biodegradable products have raised great interest since sustainable development policies tend to expand with the decreasing reserve of fossil fuel and the growing concern for the environment. These polymers bring a significant contribution to the sustainable development in view of the wider range of disposal options with minor environmental impact. As a result, the market of these environmentally friendly materials is in rapid expansion, 10–20 % per year. Consequently, biodegradable polymers are the topics of much research. Biodegradable polymers can be mainly classified as agropolymers (starch, chitin, protein...) and biodegradable polyesters [polyhydroxyalkanoates, poly(lactic acid)...]. These latter, also called biopolyesters, can be synthesized from fossil resources but main productions are obtained from renewable resources. This chapter intends to present these polymers regarding the synthesis, the structure, properties and their applications.

Biodegradable Polymers
Biodegradable materials are used in packaging, agriculture, medicine and other areas. In recent years there has been an increase in interest in biodegradable polymers. Two classes of biodegradable polymers can be distinguished: synthetic or natural polymers. There are polymers produced from feedstocks derived either from petroleum resources (non renewable resources) or from biological resources...
متن کاملBiodegradable polymers for microencapsulation of drugs.
Drug delivery has become increasingly important mainly due to the awareness of the difficulties associated with a variety of old and new drugs. Of the many polymeric drug delivery systems, biodegradable polymers have been used widely as drug delivery systems because of their biocompatibility and biodegradability. The majority of biodegradable polymers have been used in the form of microparticle...
متن کاملBiodegradable polymers for ocular drug delivery.
A variety of ocular drug delivery systems, including a controlled release of the drug, drug targeting, and penetration enhancement of the drug, have been investigated. Biodegradable polymers have been widely used as the drug carrier for controlled-release systems. Biodegradable polymers release the drug as they themselves degrade and are finally absorbed within the body. Several ocular drug del...
متن کاملThe second green revolution? Production of plant-based biodegradable plastics.
Biodegradable plastics are those that can be completely degraded in landfills, composters or sewage treatment plants by the action of naturally occurring micro-organisms. Truly biodegradable plastics leave no toxic, visible or distinguishable residues following degradation. Their biodegradability contrasts sharply with most petroleum-based plastics, which are essentially indestructible in a bio...
متن کاملDossier – Bioplastics as food contact materials
1 Definition of bioplastics The two main groups of bioplastics are biobased polymers and biodegradable plastics. Biobased polymers are derived from biomass sources, which are not necessarily biodegradable. Biodegradable plastics, on the other hand, can be either made of natural or fossil sources. In 2012, the IUPAC recommended a terminology for biorelated polymers [1, 2]. Two further, special c...
متن کاملFunctionalized synthetic biodegradable polymer scaffolds for tissue engineering.
Scaffolds (artificial ECMs) play a pivotal role in the process of regenerating tissues in 3D. Biodegradable synthetic polymers are the most widely used scaffolding materials. However, synthetic polymers usually lack the biological cues found in the natural extracellular matrix. Significant efforts have been made to synthesize biodegradable polymers with functional groups that are used to couple...
