This edition of Wealth from Waste: trends and technologies takes a closer look at the different avenues that consider waste a resource for recycling and valorization rather than contemplating its disposal. The book provides insights 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.
