Aufgrund wachsender Besorgnis über Plastikwerkstoffe und deren Beitrag zur Umweltverschmutzung wurde das Recycling von Polymeren zu einem Kernthema in Politik und Wirtschaft. Diese längst überfällige Publikation fasst in einem Band Material zusammen, das bislang nur in Form von Tagungsberichten verfügbar war. Der Schwerpunkt liegt auf Polymeren, deren Recycling bisher problematisch war, wie z. B. Autoreifen, Polyurethanschäume und Konstruktionsmaterialien. Detailliert werden die Fortschritte des Polymerrecycling besprochen - vom Sortierstadium bis hin zu einzelnen Recyclingprozessen und Anwendungsmöglichkeiten des Endprodukts: Ein Abriß aktuellster Recyclingtechniken.
The last six years have seen a great shift in plastics recycling from the mechanical recycling of the early nineties towards a more integrated approach in which feedstock recycling and the recovery of incineration energy is encouraged. Based on extensive research of the international recycling industry, this book describes technological advances in polymer recycling from the sorting stage through to recycling processes and end-use applications; provides an overview of state-of-the-art recycling techniques with current and potential applications and draws together and consolidates literature in this rapidly growing field. Due to widespread growing concern over the contribution of plastics to environmental pollution, a book which does all of the above is long overdue. In the US and Europe the recycling of polymers is a major political issue and has become an expanding commercial activity. Dr. Scheirs places significant emphasis on the recycling of automobile tyres, polyurethane foams, carpets, engineering plastics and fibre-reinforced composites, all of which had been previously thought to be hard to recycle.
