Biological treatment, composting, in particular, is a relatively simple, durable and inexpensive alternative for stabilizing and reducing biodegradable waste. Co-composting of different waste sources allows to enhance the compost nutrient value. In particular, integration of ‘biosolids’ from the sanitation sector as potential input material for co-composting would provide a solution for the much needed treatment of fecal sludge from on-site sanitation systems, and make use of its high nutrient content. This research paper elaborates in detail the main parameters that govern the co-composting process as well as factors that control the production of a safe and valuable quality compost. It further explains technological options to tailor the final product to crop and farmer needs.

This report is part of a joint global research, development and demonstration effort of the United Nations Development Programme and the World Bank. It reviews current literature and practices on the co-composting of human waste together with the organic fraction of domestic solid waste. The report describes the composting process, reviews various co-composting systems, and discusses health aspects such as pathogen destruction. The uses of compost as a soil conditioner, mulch, fertilizer or for land reclamation are also described. The report also develops several cost/benefit models for economic analysis of co-composting operations and outlines the economics of the process as a whole. The focus of the analytical methodology is on developing countries. Key issues for consideration in planning for composting are also discussed. Decision makers and planners will find this report a valuable reference on co-composting when addressing waste management and resource recovery issues in the developing countries.

The European Union initially demonstrated its interest in waste in the late 70s with the progamme on Waste Recycling Research and Development. At that time composting was only present as a coordination activity and it was only later that specific research programmes in the area were within Europe which was largely instrumental in setting up a series of European conferences, seminars and work shops. Some of these have resulted in publications which have made significant contributions to developments in the understanding of composting and the use of composts. In particular the outputs from meetings in Oxford ( 1984), Udine (1986), Neresheim ( 1988) and Angers ( 1991) are worthy of note. Composting has seen significant changes since the 70s when the major thrust in Europe was using mixed municipal solid waste as a feed material. Many com posting plants which were built to use this material were closed due to the poor quality of the compost which made it very difficult to market. As a result the main areas of interest, as far as the municipa1ities are concemed, are now with biowaste and source-separated organics. This interest is apparent from the many new plants which are being constructed across Europe, and the ready market which exists for the products. In parallel with the renewed interest of the municipalities other areas, such as agriculture and the wastewater treatment industries, are also developing their own schemes.

FROM THE PREFACE The main objective of composting is to transform organic materials into a stable usable product. Often organic materials which may have limited beneficial use in their raw state or have regulatory disposal constraints can be transformed by composting into marketable products. The limits on beneficial reuse may be regulations or they may be due to the potential for materials to be putrescible or pathogenic. Composting can be a solution for each of these. The implementation of composting on a large scale (in contrast to home or backyard composting) involves materials handling. Technological implementation of composting must be consistent with the biological demand of the system. If the biological system is violated, conditions will not be optimized for composting, and problems such as odor generation, insufficient aeration or moisture, or a combination of these conditions may result. Past problems and closure of facilities have been largely due to violations of the biological systems. Product quality with respect to particle size, inclusions, moisture content and other physical aspects are a function of engineering design. A well designed system must have the biological and engineering principles in harmony at all times.

Organic waste composting is another excellent example to demonstrate the power and the benefits of nexus thinking. Even though organic waste composting itself is not a new topic, those who want to start a new project or align an ongoing project with nexus thinking, find it difficult to gather the necessary information. With nine case studies from four continents, this book aims to fill above gap in literature. While current literature on composting is often found to be limited to either soil/agriculture sector or waste management sector, this book presents a combined point of view. This open access book starts with an introductory chapter that describes the need to bring the waste management aspects and soil nutrient management aspects of compost production into one integrated theme. The relevance of nexus thinking and the Sustainable Development Goals (SDGs) are also presented in this introduction. The first three chapters after the introduction covers composting from the solid waste management and its policy aspects, taking examples from three developing countries. The next three examples are mostly about the benefits composting can provide to the soil and agriculture. These examples are also from three developing countries, but with a mixture of urban as well as rural settings. Last three chapters present more insight into the latest developments taking examples from Europe, as well as new methods adapted from the traditional styles from Africa.

Management of micropollutants and disinfection of byproducts in municipal wastewater and extraction of energy from the sludge produced in wastewater treatment plants is under constant focus. This book presents a detailed know-how regarding sustainable management of waste produced in municipal and industrial activities through novel state-of-the-art techniques used for the treatment of toxic industrial wastes and municipal wastewater. It deals with the management of municipal sludge and solid waste including leachates produced from landfill sites. It also provides detailed information for achieving the stringent standards set by regulatory bodies for municipal and industrial effluents. Features: Covers development of new novel reactor configurations for wastewater treatment. Describes handling and removal of emerging contaminants like pharmaceutical compounds, endocrine disruptors, and disinfection byproducts. Deliberates combination of wastewater and micropollution. Contains an in-depth discussion on treatment and disposal of fecal sludge. Highlights new economically feasible techniques to enhance biogas recovery from treatment plant sludges.
