This book is presented in two parts. Part I covers the problems associated with scrap tires and identifies existing and potential source reduction and utilization methods that may be effective in solving the scrap tire problem. Barriers to increased utilization and options for removing the barriers are indentified and evaluated. Part II provides information on the use of whole, scrap tires and tire-derived fuel (TDF) as combustion fuel, and on the pyrolysis of scrap tires. The use of whole tires and TDF as a primary fuel is discussed for dedicated tire-to-energy facilities. The use of whole tires and TDF as a supplemental fuel is discussed for cement manufacturing plants, pulp and paper mills, and other industrial processes. The focus of Part II is the impact of burning whole tires and TDF on air emissions.
