Pyrolysis is a recycling technique converting plastic waste into fuels, monomers, or other valuable materials by thermal and catalytic cracking processes. It allows the treatment of mixed, unwashed plastic wastes. For many years research has been carried out on thermally converting waste plastics into useful hydrocarbons liquids such as crude oil and diesel fuel. Recently the technology has matured to the point where commercial plants are now available. Pyrolysis recycling of mixed waste plastics into generator and transportation fuels is seen as the answer for recovering value from unwashed, mixed plastics and achieving their desired diversion from landfill. This book provides an overview of the science and technology of pyrolysis of waste plastics. It describes the types of plastics that are suitable for pyrolysis recycling, the mechanism of pyrolytic degradation of various plastics, characterization of the pyrolysis products and details of commercially mature pyrolysis technologies. This book also covers co-pyrolysis technology, including: waste plastic/waste oil, waste plastics/coal, and waste plastics/rubber.

Geomembranes are flexible polymeric sheets which are used as relatively impermeable liners to contain liquid and vapour. With uses ranging from canal liners to hazard waste landfills, they are used extensively in a range of industries such as water conservation, mining, construction and waste management. A Guide to Polymeric Geomembranes: A Practical Approach offers an informed overview of the developments in this field and includes: Detailed discussion of the major geomembrane typesManufacturing methodsKey performance propertiesIndustrial applicationsTesting and chemical resistance of geomembranesFailure analysis methodologyWritten by a polymer research specialist with more than fifteen years experience in industry, this practical handbook covers the manufacture, use, installation, durability, lifespan and performance of geomembranes. It covers all the information required to enable the reader to select the most suitable geomembrane material for the job.This book is a useful reference for engineers and professionals in industry, environmental consultants, polymer and materials scientists, and government agencies and policy makers. It is of particular interest to those designing, commissioning and operating waste management sites, landfills, mine leachate ponds and water containment facilities.

Provides an overview of a comprehensive range of commercial fluoropolymers with an emphasis on structure/property behaviour and their diverse fields of application.Topics covered include: crystalline and amorphous fluoropolymers, fluoroelastomers, coatings, sealants, linings, electrical properties, surface properties, effects of radiation, chemical resistance and failure modes of fluoropolymers.With chapters written by experts from industry and academia from North America, Australia, Europe, Russia and Japan, this book is truly international in scope and will be welcomed by researchers, processors and users of all types of fluoropolymer.

In the last three years, research into the nature and strength of metallocene-based materials has exploded. This is the first and only book to provide comprehensive coverage of the developments and advances in the field by such major polyolefin companies as Dow, Exxon, and Montell. The authors begin with overviews of metallocene catalysis and metallocene-based polyolefins, then discuss all areas of the technology, from applications to end-products.

The manufacture of polyolefins by metallocene catalysts represents a revolution in the polymer industry. The first, patent for a metallocene catalyst was filed in 1980 but it has been the last five years that have seen a dramatic increase in the volume of research into metallocenes and the maturing of metallocene technology. With contributions from leading experts from the US, Canada, Italy, Scandinavia, Germany and Japan, Metallocene-based Polyolefins gives comprehensive coverage of all areas of metallocene technology: catalyst structure, comonomer incorporation, polymerization mechanisms and conditions, reactor configurations, special properties, rheological and processing behaviour, comparison with conventional polyolefins and fields of application. An essential book for plastics engineers, polymer chemists, physicists, materials scientists and all those working in the plastics manufacturing and processing industries.
