Due to the rapid increase in the production and consumption processes, societies generate as well as reject solid materials regularly from various sectors. The primary goals of this book are to encourage reduction of waste at the source and to foster implementation of cost-effective integrated solid waste management systems.
The environmental impact of traditional waste management practice has become a central concern in industrialized countries. The past decades have seen a dramatic development in the technology for reducing air pollution caused by incineration as stipulated by clean air policies in industrialized countries. Toxic and/or valuable and rare elements are still dispersed into the environment under current practice for the disposal of treated or untreated waste materials. This book results from the discussion among scientists, engineers and authorities; and hopes to contribute towards the implementation of future sustainable waste management practices.
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.
Rapid population growth, high standards of living, and technological development are constantly increasing the diversity and quantity of solid waste. The production of solid municipal waste associated with the high proportion of organic waste and its improper disposal lead to considerable environmental pollution due to the emission of greenhouse gases such as methane, carbon dioxide, etc. In such a challenging environment, municipal authorities need to develop more effective solutions to manage the growing urban solid waste. Most of the municipal solid waste mainly constitutes degradable materials, which represent a significant role in greenhouse gas emissions in urban localities. Integrated solid waste management approaches must be developed and improved to manage the increasing organic fractions of municipal solid waste, which helps to reduce greenhouse emissions with potential economic benefits. A sustainable management of municipal solid waste systems constitutes a promising and attractive trend to study current consumption behaviors responsible for waste generation, and to protect the global ecosystem. This book presents the management of municipal of solid waste, including recycling and landfill technologies. Moreover, composition and types of waste will be investigated. As a result, the most appropriate and feasible scenarios for the management of municipal solid waste are presented to provide the respected readership with the scientific background for sustainable development in these processes, which are increasingly supported by innovative methodologies for holistic assessment of process sustainability.
This book contains detailed and structured approaches to tackling practical decision-making troubles using economic consideration and analytical methods in Municipal solid waste (MSW) management. Among all other types of environmental burdens, MSW management is still a mammoth task, and the worst part is that a suitable technique to curb the situation in developing countries has still not emerged. Municipal Solid Waste Management in Developing Countries will help fill this information gap based on information provided by field professionals. This information will be helpful to improve and manage solid waste systems through the application of modern management techniques. It covers all the fundamental concepts of MSWM; the various component systems, such as collection, transportation, processing, and disposal; and their integration. This book also discusses various component technologies available for the treatment, processing, and disposal of MSW. Written in view of actual scenarios in developing countries, it provides knowledge to develop solutions for prolonged problems in these nations. It is mainly for undergraduate and postgraduate students, research scholars, professionals, and policy makers.

Hardbound. The many aspects of the municipal solid waste (MSW) problem are analysed in this fifth volume in the series. Two fundamental choices were made when putting together this book. Firstly, the approach is multi-disciplinary in that it combines technological, environmental and economic analysis, and highlights the many specific inter-relationships between them in the MSW problem. Secondly, the main focus of the analysis is policy, or more precisely, usable knowledge and analysis for policy making at various levels, this being also the case with most technical contributions.
Transformation and rapid population growth in Africa indicates that urbanisation is one of the key determinants of the future of social dynamics and development of the continent. Linked to these changes are increased production levels of Municipal Solid Waste. This book provides recommendations and solutions that derive from current situations, experiences and observations in Africa. The study is an essential tool for urban planners, environmental engineering students and lecturers, environmental consultants and policy-makers; it is also a resource for municipal authorities, as it outlines future directions of Municipal Solid Waste management. These need to be considered by the municipal authorities of most African countries.
Solid waste was already a problem long before water and air pollution issues attracted public attention. Historically the problem associated with solid waste can be dated back to prehistoric days. Due to the invention of new products, technologies and services the quantity and quality of the waste have changed over the years. Waste characteristics not only depend on income, culture and geography but also on a society's economy and, situations like disasters that affect that economy. There was tremendous industrial activity in Europe during the industrial revolution. The twentieth century is recognized as the American Century and the twenty-first century is recognized as the Asian Century in which everyone wants to earn ‘as much as possible’. After Asia the currently developing Africa could next take the center stage. With transitions in their economies many countries have also witnessed an explosion of waste quantities. Solid waste problems and approaches to tackling them vary from country to country. For example, while efforts are made to collect and dispose hospital waste through separate mechanisms in India it is burnt together with municipal solid waste in Sweden. While trans-boundary movement of waste has been addressed in numerous international agreements, it still reaches developing countries in many forms. While thousands of people depend on waste for their livelihood throughout the world, many others face problems due to poor waste management. In this context solid waste has not remained an issue to be tackled by the local urban bodies alone. It has become a subject of importance for engineers as well as doctors, psychologist, economists, and climate scientists and any others. There are huge changes in waste management in different parts of the world at different times in history. To address these issues, an effort has been made by the authors to combine their experience and bring together a new text book on the theory and practice of the subject covering the important relevant literature at the same time.
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.

Abstract: Abstract of Dissertation titled Municipal Solid Waste Management and Recycling: A Comparison of Hong Kong and Beijing submitted by Cheng Choi Yu for the Degree of Master of Arts at The University of Hong Kong in June 2003 Proper management of municipal solid waste (MSW) is an integral part of any upgrading of environmental quality. In this research, the MSW management and recycling systems of Hong Kong and Beijing are discussed and compared. Although these two cities have different political, economic, social and cultural background, they share both differences and similarities in MSW management systems, including waste generation, collection, treatment, disposal and recycling. Generally speaking, the MSW management in Hong Kong is better, more advanced and comprehensive than that of Beijing. Landfilling is the only method for waste disposal in Hong Kong. However, it is not a sustainable way as there is the problem of scarcity of land for transferring into landfill sites. Thus, Hong Kong is facing the urgent need in finding a sustainable waste management method for solving this problem. This study shows that the Hong Kong SAR government is trying to adopt the waste hierarchy in which waste recovery and reduction have been paid much more attention and effort than ever before. In the case of Beijing, the hygiene and pollution are still the main problems in its MSW management. Also, waste recovery and recycling are not actively promoted by the government. Therefore, its recycling rate is low. As the waste generation is increasing rapidly which corresponds with economic growth, and its trend is quite similar to those of Hong Kong, the Beijing government can therefore draw on the experience of Hong Kong so that it can regulate its MSW management in a more sustainable manner.

Master's Thesis from the year 2005 in the subject Environmental Sciences, grade: Pass with Distinction, University of Newcastle upon Tyne, 73 entries in the bibliography, language: English, abstract: Since the pre-industrial era the concentration of carbon dioxide in the atmosphere has increased by nearly 30%, methane concentrations have more than doubled. The resulting climate change will lead to major environmental changes such as rising sea levels, shrinking mountain glaciers, the spread of infectious diseases and increased heat related mortality, impacts to ecosystems and loss in biodiversity, and agricultural shifts such as impacts on crop yields. As this increase is at least partly caused by human activity, the effort to confront anthropogenic greenhouse gas emissions has increased over the last years. Probably the most important measure implemented is the Framework Convention on Climate Change. In the EU about one third of manmade methane emissions, with a global warming potential 21 times greater than that of carbon dioxide, can be attributed to solid waste disposal. With some 60% of municipal solid waste still being disposed of to landfill without any form of pre-treatment and extensive reliance on incineration for treatment of most of the remainder, it is clear that there is considerable scope for improvement. In this report the capability of either European or national legislation to improve the actual situation on greenhouse gas emissions related to the management of municipal solid waste was investigated by using England, Germany and Bulgaria as representatives. From the results obtained by applying a LCA it becomes obvious that European legislation will improve the actual situation on the management of municipal solid waste. The greenhouse gas emissions generated in England will be reduced by more than 75% and thus result in a negative greenhouse gas flux. In Bulgaria the emissions will decline by more than 82%. With regard to the waste management hierarchy the greatest improvements will be reached by reducing the amount of biodegradable municipal solid waste from landfilling and meanwhile focusing on material recycling. To deal with the putrescible fraction biological treatment options should be preferred to thermal treatment methods. All improvements achieved by the different scenarios are based on effective source segregated collection schemes. This measure could be justified by the fact that most treatment options rely significantly on the quality of the input materials and that in comparison with the whole municipal solid waste management emissions based on collection and transportation could be neglected.

One of the big challenges that today's growing cities are coping with is the delivery of effective and sustainable waste management, together with a good sanitation. This volume provides a comprehensive presentation and overall picture of municipal solid waste management, including waste generation and characterization, waste reduction and recycling, waste collection and transfer and waste disposal. It analyses how these aspects are practiced in developing and developed countries. The traditional method of disposal – composting at different scales – is discussed, including the benefits of compost. 'Energy-from-waste-technologies' are amply discussed, with comparisons between developed and developing countries, and with parameters and conditions for successful operation of these technologies. Moreover, the construction and operational aspects of landfills – to maintain environmental safety and the health of the residents nearby – are described in depth. In addition to a chapter with case studies of several countries and cities in every continent, a special chapter is dedicated to municipal solid waste management in India, including legal provisions, financial resources, private participation and citizens' rights and obligations, and the status in three major cities. By presenting different elements that constitute a sustainable procedure, including the recovery of clean energy, this volume will serve as a guide to students in science and engineering and to key players in waste management services and policies.
Waste can be almost anything, including food, leaves, newspapers, bottles, construction debris, and chemicals from a factory, candy wrappers, disposable diapers, old cars, or radioactive materials. People have always produced waste, but as industry and technology have evolved and the human population has grown, waste management has become increasingly complex. Waste recycling involves the collection of waste materials and the separation and clean-up of those materials. Recycling waste means that fewer new products and consumables need to be produced, saving raw materials and reducing energy consumption. Waste reduction and recycling are very important elements of the local waste management framework. They help both to conserve natural resources and to reduce demand for valuable landfill space. The waste recycling services has become the one of the fastest growing industry. The growth of the waste recycling services is driven by the technology development for waste recycling. The waste management market is expected to be worth US$ 13.62 billion by 2025. Indian municipal solid waste (MSW) management market is expected to grow at a CAGR of 7.14% by 2025. India has planned to achieve a capacity of 2.9 million hospital beds by 2025 which will help bio medical waste management market to grow at a CAGR of 8.41%. The concern for bio medical waste management has been felt globally with the rise in infectious diseases and indiscriminate disposal of waste. It is to be understood that management of bio medical waste is an integral part of health care. There is a clear need for the current approach of waste disposal in India that is focussed on municipalities and uses high energy/high technology, to move more towards waste processing and waste recycling (that involves public private partnerships, aiming for eventual waste minimization driven at the community level, and using low energy/low technology resources. This book basically deals with characterization of Medical Waste, Medical Waste Data Collection Activities, Medical Waste Treatment Effectiveness, Gas Sterilization, Municipal Solid Waste, Bio-Medical Waste, Hospital Waste Incineration, Production, Use, and Disposal of Plastics and Plastic Products, Medical Waste Reuse, Recycling and Reduction, Disposal on Land, municipal and plastic waste management, Plastic Waste, incineration and number of recycling methods. The book is highly recommended to new entrepreneurs, existing units who wants to get more information of Waste Disposal & Recycling.
