Technical Document On Municipal Solid Waste Organics Processing

"Solid waste management is unquestionably an essential service that local governments provide their citizens. They have an important responsibility to make decisions regarding collection services, disposal infrastructure, waste diversion and recycling programs that are cost-effective and respond to their communities' needs. Even in communities with long-established programs and infrastructure, the management of waste continues to evolve and require informed decisions that take into consideration a complex set of environmental, social, technological, and financial factors. Communities are considering options for processing organic waste and need more detailed, objective technical guidance and reliable information on the available processing technologies. ... This Technical Document on Municipal Solid Waste Organics Processing was developed to meet this need by providing science-based, objective and user-friendly information on the various aspects of organic waste management planning and operation for organics processing of different capacities and in different locations. The most applicable and relevant proven composting and anaerobic digestion treatment approaches for implementation in Canada and the considerations applicable to their implementation are also discussed. Treatment technologies still at the research level, that are not yet commercially available, or that have not fully demonstrated technical feasibility in the Canadian context are not covered in this Technical Document"--Preface.

Offering a comprehensive approach, this title covers fundamentals, technologies, and management of biological processing of solid waste. It discusses kinetic modeling and synergistic impact evolution during bioprocessing of solid waste, environmental impacts such as greenhouse gas emission from biological processing of solid waste, energy recovery from solid waste, and biodrying of solid waste. It also presents cases and challenges from different countries, successful business models, and economic analyses of various processing options. Aimed at researchers and industry professionals in solid and hazardous waste management, this title offers a wealth of knowledge to help readers understand this increasingly important area.

This fourth edition of Organic Waste Recycling is fully updated with new material to create a comprehensive and accessible textbook: - New chapter on constructed wetlands for wastewater and faecal sludge stabilization. - New sections on: waste recycling vs. climate change and water; faecal sludge and its characteristics; hydrothermal carbonization technology; up-to-date environmental criteria and legislation and environmental risk assessment. - New case studies with emphasis on practices in both developed and developing countries have been included, along with more exercises at the end of chapters to help the readers understand the technical principles and their application. - Novel concepts and strategies of waste management are presented. - Up-to-date research findings and innovative technologies of waste recycling program are provided. This textbook is intended for undergraduate and graduate students majoring in environmental sciences and engineering as well as researchers, professionals and policy makers who conduct research and practices in the related fields. It is essential reading for experts in environmental science and engineering and sustainable waste reuse and recycling in both developed and developing countries.

Energy conversion technology has always been a main focus for researchers in order to meet the increasing demand as well as securing a clean, consistent and reliable energy supply. The constantly rising fuel price is another good reason to develop alternative systems such as wind turbines, hydropower, photovoltaic systems and other renewable energy solutions. This book contains a collection of selected research works in the areas of electric energy generation, renewable energy sources, hybrid system, electromechanical energy conversion, electric machines, power electronic converters and inverters, energy storage, smart grid and traditional energy conversion systems. The book intends to provide academic and industry professionals working in the field of energy conversion and related applications with an update in energy conversion technology, particularly from the applied perspective.

The past few years have seen the emergence of a growing, widespread desire in this country, and indeed everywhere, that positive actions be taken to restore the quality of our environment, and to protect it from the degrading effects of all forms of pollution-air, noise, solid waste, and water. Since pollution is a direct or" indirect consequence of waste, if there is no waste, there can be no pollution, and the seemingly idealistic demand for" zero discharge" can be construed as a demand for zero waste. However, as long as there is waste, we can only attempt to abate the consequent pollution by converting it to a less noxious form. In those instances in which a particular type of pollution has been recognized, three major questions usually arise: 1, How serious is the pollution? 2, Is the technology to abate it available? and 3, Do the costs of abatement justify the degree of abatement achieved? The principal intention of this series of books is to help the reader to formulate answers to the last two of the above three questions. The traditional approach of applying tried-and-true solutions to specific pollution problems has been a major factor contributing to the success of environmental engineering, and in large measure has accounted for the establishing ofa "methodology of pollution control.

The Global Waste Management Outlook is the first comprehensive, impartial and in-depth assessment of global waste management. It reflects the collective body of recent scientific knowledge, drawing on the work of leading experts and the vast body of research undertaken within and beyond the United Nations system. The six chapters inform the reader about trends, provide an analysis on governance and financial mechanisms, and offer policy advice on the way forward. The main document targeting professionals is accompanied by two summary documents, one for decision makers and the other for the public more broadly. This Global Waste Management Outlook offers a profound analysis of the enormous potential better waste management provides to assist in meeting the sustainability challenges ahead.

Uncontrolled spreading of waste materials leads to health problems and environmental damage. To prevent these problems a waste management infrastructure has been set to collect and dispose of the waste, based on a hierarchy of three principles: waste prevention, recycling/reuse, and final disposal. Final disposal is the least desirable as it causes massive emissions, to the atmosphere, water bodies and the subsoil. The emission of methane to the atmosphere is an important source of greenhouse gasses. Organic waste therefore gets a lot of attention in waste management, which for Europe can be illustrated by the issue of the Landfill Directive (99/31/EC) and the Sewage Sludge Directive (86/278/EEC). Proper treatment of organic waste may however turn this burden into an asset. In particular, biological treatment may help in developing more effective resource management and sustainable development. The following advantages may be listed: The greenhouse effect is tackled as methane emissions from landfilling are prevented Soil quality can be restored or enhanced by the use of compost in agriculture Compost may replace peat in horticulture and home gardening, reducing greenhouse emissions and wetland exploitation Anaerobic digestion has the additional benefit of producing biogas that may be used as a fuel Pesticide use can be reduced by proper use of the disease suppressive properties of compost Resource Recovery and Reuse in Organic Solid Waste Management disseminates at advanced scientific level the potential of environmental biotechnology for the recovery and reuse of products from solid waste. Several options to recover energy out of organic solid waste from domestic, agricultural and industrial origin are presented and discussed and existing economically feasible treatment systems that produce energy out of solid waste and recover useful by-products in the form of fertiliser or soil conditioner are demonstrated. The potential of environmental biotechnology is highlighted from different perspectives: societal, technological and practical.
