High Rate Composting Of Municipal Solid Waste

Due to high operating, transport costs and the poorly developed market for compost, the expected profits could not be realized as planned. Since 1990s, there is a trend towards smaller, manually operated composting plants at community level, initiated primarily by citizen initiatives or non-governmental organizations. Hence it recommended that instead of setting up single large compost plants, it would be beneficial and more effective to set up several small composting plants. Decentralized composting can be operated by an appropriate technology and implemented at reduced investment and operating costs. An efficient and promising technique in decentralized composting is the rotary drum composter. It is an excellent concept for smaller communities or in the case of projects that require a rapid and an enclosed pathogen killing process. This book, therefore, provides information on operational aspects and compost dynamics for the mixed municipal organic wastes in a rotary drum composter. The investigations should be useful for professionals in waste management fields, urban local bodies and institutional bodies.

Compiling knowledge gained through more than 50 years of experience in environmental engineering technology, this book illustrates the application of fundamental concepts in microbiology to provide a sound basis for the design and operation of various biological systems used in solving environmental challenges in the air, water, and soil. Environmental Pollution Control Microbiology emphasizes the quantitative relationships of microbial growth and metabolism, beginning an examination of the overall metabolism and resulting growth of bacteria, fungi, algae, protozoa, rotifers, and other microorganisms and explains how bacteria bring about the stabilization of biodegradable organic pollutants.

Composting and Recycling Municipal Solid Waste is a comprehensive guide that identifies, describes, explains, and evaluates the options available when composting and recycling municipal solid waste (MSW). The book begins with an introductory chapter on the nature of MSW and the importance of solid waste management programs and resource recovery. Chapter 2 discusses MSW storage and collection, with emphasis on recyclables. Chapter 3 examines issues involved in determining the quantity, composition, and key physical characteristics of the MSW to be managed and processed. The book's other chapters cover topics such as the steps required for processing MSW for material recovery, the use of uncomposted organic matter as a soil amendment, composting and use of compost product, the marketing of recyclables, biogasification, and integrated waste management. Composting and Recycling Municipal Solid Waste provides essential information needed by solid waste professionals, consultants, regulators, and planners to arrive at rational decisions regarding available economic and technological resources for MSW composting and recycling.

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.

Currently, it is a serious concern to manage waste in the environment. Therefore, detailed knowledge of heavy metals, their eco-toxicological and health effects and ecofriendly approaches for their immobilization and detoxification is urgently required to control and minimize the environmental pollution. Composting is one of the popular methods in waste management and there are a lot of issues pertaining to composting. One of it is the leaching of heavy metals. This book discusses thoroughly, the availability, leachability and the speciation of heavy metals in the entire process of composting.

The proceedings of the Seventh International Conference on Waste Management and the Environment follow on from the success of previous meetings beginning in 2002. Topics covered include: Environmental impact; Reduce, reuse, recycle & recovery (4Rs); Energy from waste; eWaste; Landfill optimization and mining; Environmental remediation; Legislation.

This book is the first volume in a three-volume set on Solid Waste Engineering and Management. It provides an introduction to the topic, and focuses on legislation, transportation, transfer station, characterization, mechanical volume reduction, measurement, combustion, incineration, composting, landfilling, and systems planning as it pertains to solid waste management. The three volumes comprehensively discuss various contemporary issues associated with solid waste pollution management, impacts on the environment and vulnerable human populations, and solutions to these problems.

Interest in solid waste disposal has been growing since the early 1960s, when researchers emphasized the potential for solid waste to harbor pathogenic microorganisms. Since then, society has become more interested in the environmental impacts of solid waste treatment and disposal, and how biological processes are used to minimize these impacts. This new text provides a basic understanding of the unique microbial ecosystems associated with the decomposition of municipal solid waste (MSW). It addresses the challenges of sampling and assaying microbial activities in MSW and describes preferred methods. The decomposition of MSW under anaerobic conditions in landfills and digestors is described, as well as under aerobioconditions during composting. The Microbiology of Solid Wastes discusses the need to consider MSW as an integrated system of collection, recycling, treatment, and disposal. A better understanding of solid waste microbiology will contribute to safe and economical solid waste management. Microbiologists, environmental engineers, and solid waste managers will all find this a useful reference.

With the increased interest in and demands for compost from commercial horticultural industries, composting is on the verge of becoming an economically feasible option for waste management. While horticultural producers can create some of the compost to meet their own needs, demand has grown beyond what they can supply for themselves and others. Compost Utilization in Horticultural Cropping Systems gives you the tools to meet the needs of this growing industry. Consider these statistics: Americans generate about 200 million megagrams of municipal solid waste per year The agricultural market for compost could reach over 680 million m3 per year Two horticultural areas together account for over 50% of compost use: landscaping (31%) and food crop production (25%) Now consider this: Proven benefits of compost use, including plant disease suppression, better moisture retention, supplying plant nutrients, and building soil organic matter Increased pressure on peat supplies and wider availability of compost products Creation of composting enterprises by the horticultural industry in response to its own needs, rising disposal fees for organic waste, and consumer demand for compost at retail centers The first book to establish a composite of the existing scientific knowledge on the use of compost in commercial horticultural enterprises, Compost Utilization in Horticultural Cropping Systems gives you a comprehensive review of the production, use, and economics of compost. It covers production methods, compost quality and the parameters associated with its measurement, and the biological, chemical, and physical processes that occur during composting. Rather than searching for information in various places, now you can find all the information you need in one convenient source.
