Environmental Management of Energy from Biofuels and Biofeedstocks (eBook, PDF)

• Format: PDF

Produktbeschreibung

The most comprehensive and thorough volume on the environmental aspects of energy from biofuels and biofeedstocks Biomass is a renewable resource whose utilization has received great attention due to environmental considerations and the increasing demands of energy worldwide. Since the energy crises of the 1970s, many countries have become interested in biomass as a fuel source to expand the development of domestic and renewable energy sources, reduce the environmental impacts of energy production, provide rural prosperity for its poor farmers, and bolster a flat agricultural sector. This first volume in the Energy and the Environment series discusses the environmental impacts and social concerns of energy production in its various forms, offering comprehensive coverage of the many available biofuels. Starting with a historical overview, Environmental Management of Energy from Biomass and Biofeedstocks: * Presents a full technological treatment of the processes, engineering, and applications of biofuels and biofeedstocks * Describes the relevant technologies and their environmental impacts * Covers the social aspects, economic aspects, and the future of biofuels * Discusses a variety of biofuels and their possible use and applicability in different countries
