Introduction to Plastics Recycling, 2nd Edition (Soft-backed)
Smithers Rapra, 2007
By Vannessa Goodship
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.
