The current common practice of waste land-filling is unacceptable due to legislation pressures, rising prices and the poor biodegradability of commonly used substances. Hence, recycling appears to be the best solution. The objective of this book is to discuss recycling techniques and procedures of various substances, as well as to propose possible uses of the recycled products. The book will be beneficial for professionals, recycling corporations, researchers, academicians and graduates in the areas of waste management and polymer recycling. Other major topics included are polymer recycling using chemical, thermochemical (pyrolysis) or mechanical procedures, recycling of waste tires, pharmaceutical packaging and hardwood kraft pulp, and possible usage of recycled wastes.
