Japan was ahead of the rest of the world when it introduced intermediate processing of municipal waste by such means as incineration in the 1960s. Owing to the small land area of the country and the difficulty in securing landfill sites, the incineration ratio of municipal combustible waste had reached 100% by the 1990s. Along with the landfill of incineration residues, proprietary technologies such as high salt leachate treatment, desalination treatment, by-product recycling, a focus on the resource of incineration residues, sea surface landfill sites, and covered type landfill sites have spread and developed since then. This book describes the introduction of incineration facilities starting in the 1960s, landfill technology, and issues arising after 1990 following the introduction of the facilities. The necessity of a total system from incineration to landfill is explained as well. The volume is a valuable resource for countries that plan to introduce intermediate processing such as incineration and for countries that are developing a waste management policy.

Solid waste management issues, technologies and challenges are dynamic. More so, in developing and transitory nations in Asia. This book, written by Asian experts in solid waste management, explores the current situation in Asian countries including Pacific Islands. There are not many technical books of this kind, especially dedicated to this region of the world. The chapters form a comprehensive, coherent investigation in municipal solid waste (MSW) management, including, definitions used, generation, sustainable waste management system, legal framework and impacts on global warming. Several case studies from Asian nations are included to exemplify the real situation experienced. Discussions on MSW policy in these countries and their impacts on waste management and minimization (if any) are indeed an eye-opener. Undoubtedly, this book would be a pioneer in revealing the latest situation in the Asian region, which includes two of the world’s most dynamic nations in the economic growth. It is greatly envisaged to form an excellent source of reference in MSW management in Asia and Pacific Islands. This book will bridge the wide gap in available information between the developed and transitory/developing nations.

This volume provides developing and transition-economy countries with information sources and selected technologies relating to the environmentally-sound management of municipal solid waste. It aims to provide an inventory of available information sources and an analysis of sound practices.

MUNICIPAL SOLID WASTE TO ENERGY CONVERSION PROCESSES A TECHNICAL AND ECONOMIC REVIEW OF EMERGING WASTE DISPOSAL TECHNOLOGIES Intended for a wide audience ranging from engineers and academics to decision-makers in both the public and private sectors, Municipal Solid Waste to Energy Conversion Processes: Economic, Technical, and Renewable Comparisons reviews the current state of the solid waste disposal industry. It details how the proven plasma gasification technology can be used to manage Municipal Solid Waste (MSW) and to generate energy and revenues for local communities in an environmentally safe manner with essentially no wastes. Beginning with an introduction to pyrolysis/gasification and combustion technologies, the book provides many case studies on various waste-to-energy (WTE) technologies and creates an economic and technical baseline from which all current and emerging WTE technologies could be compared and evaluated. Topics include: Pyrolysis/gasification technology, the most suitable and economically viable approach for the management of wastes Combustion technology Other renewable energy resources including wind and hydroelectric energy Plasma economics Cash flows as a revenue source for waste solids-to-energy management Plant operations, with an independent case study of Eco-Valley plant in Utashinai, Japan Extensive case studies of garbage to liquid fuels, wastes to electricity, and wastes to power ethanol plants illustrate how currently generated MSW and past wastes in landfills can be processed with proven plasma gasification technology to eliminate air and water pollution from landfills.

Waste Management is one of the key problems of modern society due to the ever-expanding volume and complexity of discarded domestic and industrial waste. Society is increasingly aware of the need to establish better practices and safer solutions for waste disposal. This requires further investigation into disposal methods and recycling as well as new technologies to monitor landfills, industrial mining wastes and chemical and nuclear repositories. This creates a need for more research on current disposal methods such as landfills, incineration, chemical and effluent treatment, as well as recycling, clean technologies, waste monitoring, public and corporate awareness and general education. Unfortunately, many of the policies adopted in the past were aimed at short term solutions without due regard to the long term implications on health and the environment, leading in many cases to the need to take difficult and expensive remedial action. The desired direction of Waste Management is towards sustainable strategies. The approach which has emerged as the most promising has been called 4Rs, where reduction, reuse, recycling and recovery are seen as the best actions. This largely decreases the volume of waste that needs final disposal. Recovery refers to the establishment of two new classifications, those of Secondary Raw Materials (SRM) and of Refuse Derived Fuel (RDF). They both relate to useful products obtained from waste and make a shift from the mere recycle or reuse – mostly seen as a way to reduce dumping – to the valuable employment of such matter within the production cycle. Another aspect of this revolution is happening subtly and gradually by people buying waste; particularly eWaste and some types of plastic, the so-called technical waste. This is happening due to the strong demand and high price of certain new materials and the possibility of sorting out waste in developing regions of the world. As a result, a market in Secondary Raw Materials (SRM) has developed. Covering various areas under the topic of Waste management, this volume contains a selection of papers presented at the 10th International Conference on Waste Management and the Environment.

Municipal Solid waste (MSW) have caused administrative and environmental problems in many municipalities, and resource saving and environmental protection have become important principles in managing the increasing and diversified MSW. MSW contain a large amount of quasi-wastes that are of some resource or even exchange value. Resource recovery from MSM offers savings of resource and energy, reduction of the refuse quantity to be disposed of, a prolonged and efficient use of landfilling space, reduction of environmental impacts caused by waste disposal and establishment of a resource-saving and environment-conserving society. Presently, in Japan, more than half the number of municipalities recovery use goods, raw materials, energy and other materials from their MSW, at the before-discharge from individual home stage, collection stage, treatment stage and landfill stage.
