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.
The International Water Association's 2nd World Water Congress held in Berlin in October 2001 was, like its predecessor, a resounding and well attended success. At the centre of its programme were over three hundred oral presentations addressing the drinking water, sanitation, stormwater and environmental needs of communities worldwide. From the large number of oral presentations, after full peer review, 49 papers dealing with aspects of integrated water resources management have been selected for this issue. Topics include: modelling and decision support systems; water efficiency; leadership and public participation; assessment methodologies; urban drainage; diffuse pollution; rehabilitation of sewer systems; water reuse; sustainable sanitation; and appropriate technologies for developing countries. With some of the world's leading experts as authors, highlighting research results and their practical applications, these proceedings are an essential compilation of the latest advances relating to integrated water resources management, from the scientific basis of sustainable sanitation through to developments in policy support and utility management.

Waste-to-Resource System Design for Low-Carbon Circular Economy equips the user with the necessary knowledge to carry out the preliminary design and optimization of economically viable and environmentally friendly waste-to-resource systems. This book covers the state-of-the-art development of technologies and processes in terms of six types of bioresources (i.e. energy, biohydrogen, biomethane, bioethanol, biodiesel, and biochar) that are recoverable from waste. The focused technologies and processes, such as anaerobic digestion, fermentation, pyrolysis, gasification, and transesterification are being widely applied—or have the potential to be used—towards sustainable waste management. It also covers the methods needed for the design and optimization of waste-to-resource systems, i.e., multiobjective optimization, cost-benefit analysis, and life cycle assessment, as well as systematic and representative databases on the parameters of the processes, costs, and the advantages and disadvantages of technologies. Finally, the book adopts a problem-based method to facilitate audiences to quickly gain the knowledge and skill of designing and optimizing waste-to-resource systems. - Includes an up-to-date understanding of the fundamentals and mechanisms of promising waste-to-resource technologies and processes - Describes the methods that are needed for the design and optimization of waste-to-resource systems, i.e., multiobjective optimization, cost-benefit analysis, and life cycle assessment - Provides systematic and representative databases on the parameters of the processes, costs, and advantages and disadvantages of different waste-to-resource systems - Covers different types of waste-to-resource technologies, categorized into waste-to-energy, waste-to-biohydrogen, waste-to-biomethane, waste-to-bioethanol, waste-to-biodiesel, and waste-to-biochar
The strategic planning of urban water systems is a complex task. The Urban Water programme covered projects from various disciplines at 9 Swedish Universities, from 1999 to 2006. The projects developed a "toolbox" for strategic planning of drinking-, waste- and stormwater management, covering aspects such as the environment, health and hygiene, financing, organisation, households, and technical function. Strategic Planning of Sustainable Urban Water Management synthesises the results and presents a comprehensive approach, which includes not only the technical, economic and environmental aspects, but also the challenges of institutional capacity and public participation in the planning process. Furthermore, the experience from a number of case studies are summarised and can offer readers inspiration for their own planning situations.
Sustainability is a key driving force for industries in the chemical, food, packaging, agricultural and pharmaceutical sectors, and quantitative sustainability indicators are being incorporated into company reports. This is driving the uptake of renewable resources and the adoption of renewables. Renewables' can either be the substituted raw materials that are used in a given industry, (e.g. the use of biomass for fuel); the use and/or modification of a crop for use in a new industry (e.g. plant cellulose), or the reuse of a waste product (e.g. organic waste for energy production). This is the first book in the Wiley Renewable Resources series that brings together the range of sustainability assessment methods and their uses. Ensuing books in the series will look at individual renewable materials and applications.
Water Recycling and Resource Recovery in Industry: Analysis, Technologies and Implementation provides a definitive and in-depth discussion of the current state-of-the-art tools and technologies enabling the industrial recycling and reuse of water and other resources. The book also presents in detail how these technologies can be implemented in order to maximize resource recycling in industrial practice, and to integrate water and resource recycling in ongoing industrial production processes. Special attention is given to non-process engineering aspects such as systems analysis, software tools, health, regulations, life-cycle analysis, economic impact and public participation. Case studies illustrate the huge potential of environmental technology to optimise resource utilisation in industry. The large number of figures, tables and case studies, together with the book's multidisciplinary approach, makes Water Recycling and Resource Recovery in Industry: Analysis, Technologies and Implementation the perfect reference work for academics, professionals and consultants dealing with industrial water resources recovery. Contents Part I: Industrial reuse for environmental protection Part II: System analysis to assist in closing industrial resource cycles Part III: Characterisation of process water quality Part IV: Technological aspects of closing industrial cycles Part V: Examples of closed water cycles in industrial processes Part VI: Resource protection policies in industry
Life is often considered to be a journey. The lifecycle of waste can similarly be considered to be a journey from the cradle (when an item becomes valueless and, usually, is placed in the dustbin) to the grave (when value is restored by creating usable material or energy; or the waste is transformed into emissions to water or air, or into inert material placed in a landfill). This preface provides a route map for the journey the reader of this book will undertake. Who? Who are the intended readers of this book? Waste managers (whether in public service or private companies) will find a holistic approach for improving the environmental quality and the economic cost of managing waste. The book contains general principles based on cutting edge experience being developed across Europe. Detailed data and a computer model will enable operations managers to develop data-based improvements to their systems. Producers oj waste will be better able to understand how their actions can influence the operation of environmentally improved waste management systems. Designers oj products and packages will be better able to understand how their design criteria can improve the compatibility of their product or package with developing, environmentally improved waste management systems. Waste data specialists (whether in laboratories, consultancies or environ mental managers of waste facilities) will see how the scope, quantity and quality of their data can be improved to help their colleagues design more effective waste management systems.
