Polymers constitute a separate area on the environmental issues. Due to the generation of excessive amounts of polymers wastes by industries and householders, the world has confronted a serious crisis. Furthermore, due to the rising environmental awareness, economical and petroleum concerns an increasing attempt is being made to cope with the polymers wastes during the last few years. The traditional methods used to dispose polymer wastes such as combustion of polymers wastes or burying underground show a negative influence on the environment.From the existing studies, it seems that the recycling process is one of the best techniques to treat the waste polymer products. Recycling of polymers through advanced techniques is an important topic that is driven by both the 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 recycling of waste polymers include mechanical recycling, chemical or feedstock recycling and energy recovery. Keeping in mind the advantages of the recycled polymers, this book gives an overview of on 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 the 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:- Present state-of-the-art recycled polymers from different resources - Includes contributions from world renowned experts on recycled polymers - Discusses the properties and durability of recycled polymers based materials - Highlights new frontiers in the properties and applications of recycled polymers - Focus on recyclability and up-to date progress on recycled polymers - Effect of different parameters on properties of recycled polymers are presented - Solutions for widespread application are recommended - Current problems, recent developments and applications are discussed
