About the 2nd Edition
Although recycling has a long history, it is only relatively recently that environmental protection and waste management issues have come to the forefront of both public and political awareness. Outside the fields of expertise, generally little is known about either plastics or their recyclability. As in the successful first edition, this book provides straightforward information on plastic materials and technology, including the options for recycling plastics, with special focus on mechanical recycling. It touches on all the major problems associated with recovering and recycling plastics at a level intended to be accessible to any reader with an interest in this field, whatever their background. It also looks at some of the broader issues surrounding successful waste management of plastics. This new edition reflects the great strides that have been made to increase recycling rates worldwide in recent years. It considers the expansion of infrastructure in the UK to support plastic recycling and major achievements that have been made in gaining widespread public support and participation for recycling schemes; specifically the need to manage waste on an individual household level. Current issues surrounding council recycling of plastic bottles, and the practice of providing free plastic carrier bags by supermarkets, are also considered. Biopolymers are expected to have a major impact on plastic markets in the future and therefore some of the issues of biodegradability versus recycling are expanded in this second edition, as is the wider context of life cycle analysis and legislation.

Book Review From the 1st Edition
Whilst public awareness of the need for recycling plastics has developed over the last few years, the practicalities of dealing with reusable polymers has remained a sort of 'black box' for those not actively involved. The media have championed the recent developments, and recycling is becoming prevalent, but for many, mystery wraps its workings.
This compact and well thought-out book neatly unwraps this problem by explaining, in clear and easily grasped sections, the rigors of recyling plastics. It could be of use to anyone who wishes to know more about the processes involved and demands little prior knowledge. The first chapter deals with recycling in political and economic terms. The second gives a basic introduction to common polymers along with their uses before and after recycling. The third introduces the rheological problems encountered and explains how to test plastics with respect to their end use. After a brief look at the methods used for sorting disposed plastics in chapters 4 and 5, chapter 6, by far the largest, distinguishes the various processes applicable to each type of waste, with detailed explainations of extrusion and compounding techniques, injection, blow, compression and intrusion molding, and compares these and other industrial methods with respect to their efficiency and applicability in recycling. Following this, chapter 7 details additives and their effects on recyclates and plastics in general. Alternative methods such as chemical recycling and energy recovery, for example by incineration, are presented in chapter 8. Chapter 9 gives a brief but thorough review of the social, educational and economic aspects, and also discusses the relevance of designing consumables for recycling. To quote, "Recycling ... begin(s) with the conception of a new product." The final chapter considers a case study of European incentives towards recycling and diversion from land fill. The book ends with a useful list of abbreviations and a glossary of terms.
This book has been well written and great care is taken to make the information accessible. The lucid style and numerous internet based references should help any reader explore a promising area, and should, by design, lead to many returns.
