Biomethanization of the Organic Fraction of Municipal Solid Wastes is a comprehensive introduction to both the fundamentals and the more practical aspects of the anaerobic digestion of organic solid wastes, particularly those derived from households, that is, the organic fraction of municipal solid wastes (OFMSW). It can be used as a textbook for specialized courses and also as a guide for practitioners. In the first part, the book covers the relevant aspects of anaerobic digestion (AD) of organic wastes. The fundamentals and kinetic aspects of AD are reviewed with particular emphasis on the aspects related to solid wastes. This introduction is necessary to have a comprehensive view of the AD process and to understand the practical principles as well as the origin of possible problems arising from the management of the process. Chapter 2 emphasizes the role of kinetics in designing the reactor, paying special attention to existing models, particularly the dynamic ones. Through this introduction, it is intended to facilitate the technology transfer from laboratory or pilot plant experiences to full-scale process, in order to implement improvements in current digesters. Laboratory methods are described for the analysis and optimization of reactor performance, such as methanogenic activity tests or experimental evaluation of the biodegradation kinetics of solid organic waste. The different reaction patterns applied to industrial reactors are outlined. Industrial reactors are classified in accordance with the system they use, pointing out advantages and limitations. Co-digestion, enabling the co-treatment of organic wastes of different origin in a more economically feasible way, is described in detail. Examples of co-digestion are given, with OFMSW as a base-substrate. Finally, full-scale co-digestion plants are discussed. Various types (mechanical, biological, physico-chemical) of pre-treatment to increase the biodegradability, and thus the yields of the process, are reviewed in detail. The use of the fermentation products of anaerobic digesters for biological nutrient removal processes in wastewater treatment plants is described. This constitutes an example of integrated waste management, a field in which both economic and technical advances can be achieved. Balances are given to justify the approach, and a full-scale case study is presented. The important topic of economics and the ecological advantages of the process are emphasized. The use of compost, the integration with composting technology, and advantages over other technologies are detailed in the framework of an environmental impact assessment of biowaste treatment. Finally, the anaerobic digestion of MSW in landfills is reviewed in detail, with emphasis on landfill process enhancement and strategies for its application.

Environmental scientists and engineers are faced with the challenge of how to manage increasing amounts of solid waste. Furthermore, waste management officials are constantly faced with the question "Which option is the most appropriate one in this situation, and how does it compare to other options?" For these individuals, and for the general public, Municipal Solid Wastes: Problems and Solutions helps to answer this and other questions by presenting the issues of waste handling and disposal-from general management concepts to specific techniques. Each topic is carefully reviewed: problems are presented, and possible solutions are discussed. Legislation that affects recycling and disposal is covered.

Motivation The other day I was waiting at the station for my train. Next to me a young lady was nonchalantly leaning against the wall. Suddenly, she took a cigarette pack out of her handbag, pulled out the last cigarette, put it between her lips, crushed the empty pack, threw it on the ground and hedonistically lit the cigarette. I thought to myself, "What a behavior?!". The nearest trashcan was just five meters away. So I bent down, took the crushed pack and gave it back to her, saying that she had lost it. She looked at me in a rather deranged way, but she said nothing and of waste to the trashcan. brought the piece Often people are not aware of the waste they produce. They get rid of it and that's it. As soon as the charming lady dropped the cigarette pack, the problem was solved for her. The pack was on the ground and it suddenly no longer belonged to her. It is taken for granted that somebody else will do the cleaning up. There is a saying that nature does not produce waste. For long as humans obtained the goods they needed from the ground where they lived, the waste that was produced could be handled by nature. This has drastically changed due to urbanization and waste produced by human activities has become a severe burden.

Solid waste has grown into a relatively difficult problem to solve for those responsible for its management; these responsibilities include the collection, transport, treatment, and disposal of solid wastes, particularly wastes generated in medium and large urban centres. This problem is even more intense in economically developing countries, where the financial, human, and other critical resources are scarce in general. In the last decade, there has been a great interest and awareness regarding the environmentally safe management of waste worldwide, centralised in legislative, administrative, standardisation, and research activities in this field. Therefore, it is essential to develop short- and long-term waste management strategies (often named the 3Rs) and their consequent implementation in compliance with the formulated priorities for waste: (1) Reduce, (2) Recycle, (3) Reuse and (4) environmentally safe disposal. Several contradictions and lack of agreement still exist, even regarding the major basic definitions, e.g., which material should be treated as "waste" and which as a "beneficial raw material", which wastes are "hazardous" and which are "non-hazardous", etc. Quite often, different approaches and as a consequence, waste management/disposals are adopted for the same situation/materials. Environmental risk assessment procedures and mode of actions are varied greatly not only within national levels, but also at regional levels within the same country by different groups of scientists and/or policy makers. The general idea of the book has arisen from the mutual experience of many specialists in numerous disciplines from different countries involved in the problem of environmental assessment, economic and monitoring approaches, and control approaches for chemicals generated from solid waste disposal. Solid waste worldwide issues nowadays reflect the complexity and unbalanced development of our world at the beginning of the 21st century. This book covers a broad group of wastes, from biowaste to hazardous waste. The contributors to the book are recognised experts in the diverse fields associated with the issues of waste management and the reuse-recycle of materials, and are from different parts of the world. Authors present their experience and approaches considering both international and national/local specifics. The book is addressed to the wide range of end-users, decision-makers and professionals involved in environmental and agricultural issues: administration, designers, manufacturers, policy makers, farmers, researchers, academics and university students, and is focused on waste properties, environmental behaviour and management in an environmentally safe way. It was not the intention of the editor/authors to exhaust the subject, which is intensely broad, but to give a general idea with updating trends in the field of solid waste management concerning disposal, monitoring, assessment and remedial options, which are demonstrated also in case studies. The authors hope that this book to some extent will contribute to the trials and efforts for the proper, environmentally safe practices of solid waste disposal, and will provide state-of-the-art information and discussion, monitoring strategies, advanced approaches and methods, techniques and equipment for environmentally safe disposal and remediation of solid wastes.

Incineration has been used widely for waste disposal, including household, hazardous, and medical wasteâ€"but there is increasing public concern over the benefits of combusting the waste versus the health risk from pollutants emitted during combustion. Waste Incineration and Public Health informs the emerging debate with the most up-to-date information available on incineration, pollution, and human healthâ€"along with expert conclusions and recommendations for further research and improvement of such areas as risk communication. The committee provides details on: Processes involved in incineration and how contaminants are released. Environmental dynamics of contaminants and routes of human exposure. Tools and approaches for assessing possible human health effects. Scientific concerns pertinent to future regulatory actions. The book also examines some of the social, psychological, and economic factors that affect the communities where incineration takes place and addresses the problem of uncertainty and variation in predicting the health effects of incineration processes.
