Paperback. Zustand: new. Paperback. Predominantly organic wastes can be effectively treated by biological means to yield useful end products like methane gas as fuel and digested slurry as soil conditioner. Inert materials like plastics are effectively blended with other building materials, thereby improving the quality of the finished product and at least partially solving the problem of disposal of plastics. Inorganic wastes are excellent candidates for recovery of reusable building materials like sand and fine aggregate. Recycling of useful components from e-wastes goes a long way in reducing environmental pollution by toxic and hazardous wastes. This book places before the reader different ways and means used by scientists and engineers to minimize pollution of our natural resources and their overexploitation. Industrial solid wastes, unlike effluents and gaseous emissions, receive relatively less attention in terms of treatment, reuse, recycle, and recovery of useful by-products. These solid wastes have great potential for recovery and reuse. Shipping may be from our UK warehouse or from our Australian or US warehouses, depending on stock availability.

Hardcover. Zustand: new. Hardcover. The book provides insight into the possible technological innovations and options that can be adopted, along with the current trends and opportunities that are available worldwide for converting waste into value-added resources. In the individual chapters, authors have discussed and reviewed the possible options for conversion of various waste streams generated from municipalities and other urban establishments and biomass-based waste generated from argo-based industries and different industrial activities into an energy resource. The book also looks into the regulatory framework available in the country, which is required at every stage of the life cycle of waste, and the needs for improvement of this framework. This edition will serve as an important reference for a wide range of stakeholders - from policy-makers to environmentalists, development practitioners, academicians, waste management experts, researchers, and corporate decision-makers. This edition of Wealth from Waste takes a closer look at the different avenues that consider waste a resource for recycling and valorization rather than contemplating its disposal.
