Landfill Technology

Landfill Technology covers the selection, design, operation, and final reinstatement of landfill sites. This book is composed of seven chapters that also discuss the theory and practice of landfill technology. After briefly dealing with the composition of municipal and industrial wastes, this book goes on examining the hydrological aspect and site selection planning of a landfill site, including the economic and environmental impact assessments. These topics are followed by a chapter focusing on the several components of site preparation works, such as plant and machinery, methods of landfill operation, and waste disposal. Another chapter describes the involved microbiological processes, biodegradation, gas migration, and leachate production in landfill. Other chapters are devoted to the control and treatment of leachate pollution. These treatment options include aerobic and anaerobic, biological nitrification, ammonia desorption, and leachate recycling. The concluding chapter considers a wide range of afteruse and engineering problems occurring in landfill rehabilitation.
