"One smart book...delving deep into the history and implications of a daily act that dare not speak its name."--"Newsweek
"
Bodily waste is common to all and as natural as breathing. We prefer not to talk about it, but we should--even those of us who take care of our business in pristine, sanitary conditions. Disease spread by bodily waste kills more people worldwide every year than any other single cause of death. Even in the United States, nearly two million people have no access to an indoor toilet, while the sewers of major cities worldwide are an infrastructure disaster waiting to happen. With razor-sharp wit and crusading urgency, mixing levity with gravity, "The Big Necessity" breaks the silence, turning the taboo subject into a cause with the most serious of consequences.

This book focuses on sustainable solid waste management in an urban context and gives an example of how a modern city can work with waste management for increased sustainability in close cooperation with the academy. The book describes challenges which the city is facing and presents a case on how these can be tackled based on several research and development projects performed in the City of Malmoe over the last decade. In these projects, the city has worked as a test bed for new solutions, developed with and evaluated by the university. The projects and evaluations of the same have been developed with a multi-dimensional approach; including technical aspects, resource efficiency, economic parameters, information strategies towards households and user friendliness. Methods used for evaluation are presented in a comprehensive way together with a discussion on how results from performed evaluations have affected the solid waste management policy making in the city. The book describes a bridging over a commonly noticed gap between research on the one hand and policy making and technical management on the other. Several examples are given on how academy and real life and full-scale developments in the city can have a fruit-full collaboration, where feed-back from evaluation of made changes are used for continuous improvements - at the same time as the actual needs from the city forces the academy to develop new methods for evaluations and develop new solutions to previously un-known or un-addressed problems.

A sustainable feedstock supply is one of the primordial issues for the transition towards the bio-based economy. Therefore, the resource base needs to be identified from the perspective of supply and demand. The exploitable biomass is of a highly heterogeneous origin, either derived from specially grown crops or from crop residues of food and feed production, forestry residues and marine flora. Municipal waste, manure and animal products and industrial wastes also need to be considered as potential resources for bio-based products and services. In this regard, enzymes are known to play a pivotal role not only at the stage of production of these value-added products, but also as an important component of value-added products from different alternative biomasses. Therefore, enzymes become an important factor as value-added products and for value-added products. The use of enzymes holds great potential value for industries in many sectors, including energy, organic chemicals, polymers, fabrics and healthcare products. In general, an enzyme based bio-economy offers many benefits and opportunities. For completed book description, please visit our link below.

Millions of tons of municipal solid wastes (MSW) comprising a great proportion of 'food & green garden wastes' generated from homes and institutions are ending up in the landfills everyday, creating extraordinary economic problems for the local government and environmental problems for the society due to increasingly high cost of landfill construction, waste disposal and monitoring for emission of powerful 'greenhouse gases', 'toxic gases' and discharge of 'leachate' with serious risk of polluting groundwater. Studies indicate that vermi-composting of food and garden wastes by waste-eater earthworms is more efficient over the conventional aerobic systems. This book explores the possibilities of management in this area.

Currently, the management of solid waste represents a major economic and environmental issue throughout the world. Trends in waste generation show an increase in the volumes of waste produced in most countries and it is clear that the trend will continue. The treatment and disposal of solid waste involves a range of processes including landfill, incineration and composting, all of which may result in emissions to the environment. Municipal investments are said to be highly capital-intensive. As a result, every investment needs to be preceded by the economic analysis which allows for the estimation of the effectiveness of the investment. Investments are made to make profits and to increase savings. This book presents current research in the study of municipal solid waste, with a particular focus on recycling and cost effectiveness.

Despite significant improvements in pollution abatement and environmental remediation over the past several decades, billions of people around the world continue to live in unsafe and unhealthy physical environments with great risks to their health. Environmental issues concerning wastewater treatment in particular are quite considerable. The authors of this book take a deeper look at the contaminated soils and waters which pose major environmental, agricultural and human health problems world-wide. Alternatives for the sewage sludge final disposal from the wastewater treatment are also assessed from a life cycle assessment (LCA) point of view in order to identify the best environmental alternative. In addition, the generation of solid wastes constitutes a serious environmental problem, particularly in Cuba, where there is no waste selection system, so wastes from different origins are buried in landfills. This book explores recent research done on municipal solid waste (MSW), specifically based in Havana Cuba. Furthermore, as explained in this book, one of the possible alternatives for reducing the contaminant load from solid waste is that of reuse/recycle. A brief report on the development of electrodes (Carbon resin) from solid wastes is included in an attempt to encourage recycle and reduce environmental pollution through discarded batteries. Other chapters in this book report on an investigation conducted on iron doped carbon resin electrodes, municipal solid waste (MSW) management in Cameroon, effective and efficient litter management in nations with beaches, a report on medical wastes management in selected hospitals and environmentally safe methods to remediate mercury contaminated soils.

Human activity is strictly linked with the production of waste, i.e., materials and substances that are undesired and cannot be used further. On the one hand these substances are natural to the environment, eliminated from further technological process by their uselessness (e.g. mining waste), or represent new products such as anthropogenic waste, being the by-product of industrial and agricultural activities. A separate group comprises municipal waste that is not linked with production but results from human dwelling. Utilisation actions aiming at neutralising and/or removal of waste are focused on substances that due to their existing or potential chemical activity may negatively influence the biosphere. Non-active substances represent alien elements in the natural environment, but due to their passive character, their utilisation is concentrated on non-conflicting storage. Active pollutants influencing the natural environment penetrate it as gaseous emanations, fluids (sewage and effluents) and solids. This book addresses this very important issue and covers the topic of restriction of emission and removal of hazardous gaseous emanations that should be conducted in places where they are formed. Imperfection of the applied technology or its lack results in atmospheric pollution. This problem can be of local (around industrial plants, e.g. chemical works, food processing plants, around farmsteads and stock farms), country or global range (emission of CO2, nitrogen compounds, gases hazardous to the ozone layer).
