Polymers constitute a separate area of environmental issues. Due to the generation of excessive amounts of polymer wastes by industries and householders, the world has been confronted by a serious crisis. Furthermore, due to rising environmental awareness, and economical and petroleum concerns, an increasing attempt has been made to cope with polymer waste over the last few years. The traditional methods used to dispose of polymer waste, such as the combustion of polymer wastes or burying underground, exert a negative influence on the environment. From existing studies, it seems that the recycling process is one of the best techniques to treat waste polymer products. The recycling of polymers through advanced techniques is an important topic which is driven by both commercial and environmental influences. Several new techniques have been developed along with the means of reusing recycled polymers. Some of the commercially important technological processes for the recycling of waste polymers include mechanical recycling, chemical or feedstock recycling and energy recovery. Keeping in mind the advantages of recycled polymers, this book gives an overview of the properties and processing of different kinds of recycled polymers along with their composites for a range of applications. This book is unique in the sense that it deals exclusively with the properties and processing of different recycled polymers, which are otherwise considered as waste. The book is the outcome of untiring efforts of researchers from different parts of the world with extensive research experience in the field of recycled polymers across different disciplines. Some of the main features are: โข Presents state-of-the-art recycled polymers from different resources โข Includes contributions from world-renowned experts on recycled polymers โข Discusses the properties and durability of recycled polymer-based materials โข Highlights new frontiers in the properties and applications of recycled polymers โข Focuses on recyclability and up-to-date progress on recycled polymers โข Presents the effect of different parameters on the properties of recycled polymers โข Solutions for widespread application are recommended โข Current problems, recent developments and applications are discussed
