Summary
Summary
Global energy use is approximately 140 000 TWh per year. Interestingly, biomass production amounts to approximately 270 000 TWh per year, or roughly twice as much, whereas the official figure of biomass use for energy applications is 10-13% of the global energy use. This shows that biomass is not a marginal energy resource but more than capable of meeting all our energy and food needs, provided it is used efficiently. The use of food in generating energy has been extensively debated, but there is actually no need for it given the comprehensive resources available from agriculture and forestry waste.
This book discusses the biomass resources available and aspects like efficient energy use. One way of using energy efficiently is to use waste biomass or cellulosic materials in biorefineries, where production of fibers and products from fibers is combined with production of most chemicals we need in our daily life. Such products include clothes, soap, perfume, medicines etc. Conventional pulp and paper applications, bio-fuel for vehicles and even fuel for aviation as well as heat and power production are covered. The problem with biomass is not availability, but the difficulty to use the resources efficiently without harming the long-term productivity. This book covers all types of resources on a global scale, making it unique. Many researchers from all over the world have contributed to give a good coverage of all the different international perspectives.
This book will provide facts and inspiration to professionals, engineers, researchers, and students as well as to those working for various authorities and organizations.
Author Notes
Erik Dahlquist is Professor in Energy Technology at Malardalen University (MDU) in Västerås, Sweden focussing on biomass utilization and process efficiency improvements. He started working at ASEA Research in 1975 as engineer in analytical chemistry related to nuclear power, troubleshooting of electrical equipment and manufacturing processes. In 1982 he started with energy technology within the pulp and paper industry and participated in the development of year-around fuel production from peat. In 1984 ASEA started a company ASEA Oil and Gas with a focus on off-shore production systems. One area was waste water treatment and separation of oil and water. He then became technical project manager for development of a Cross Flow Membrane filter. This led to the formation of ABB Membrane Filtration. The filter is now a commercial product at Finnish Metso Oy under the name Optifilter. As part of this development work he started as an industrial PhD student at KTH and received his doctorate in 1991. In 1989 he became project leader for ABB's Black Liquor Gasification project, which resulted in a number of patents. From 1992 to 1995 he was department manager for Combustion and Process Industry Technology at ABB Corporate Research. He was also at that time member of the board of directors for ABB Corporate Research in Sweden. From January 1996 to 2002 he was General Manager for the Product Responsible Unit "PulpApplications"worldwide within ABB Automation Systems. The product area was Advanced Control, Diagnostics, Optimization, Process Simulation and Special Sensors within the pulp and paper industry. During 1997-2000 he was part time adjunct professor at KTH and from 2000 to 2002 part time professor at MDU. He has been responsible for research in Environmental, Energy and Resource Optimization at MDU since 2000. During 2001-2007 he was first deputy dean and later dean of the faculty of Natural Science and Technology. He has been a member of the board of the Swedish Thermal Engineering Research Institute division for Process Control systems since 1999. He received the ABB Corporate Research Award 1989. He has been a member of the board of SIMS (Scandinavian Simulation and Modeling Society) since 2003 and deputy member of the board of Eurosim since 2009. He has been a member of the editorial board of the Journal of Applied Energy, Elsevier since 2007. He is also a member of the Swedish Royal Academy of Engineering (IVA) since 2011. He has 21 (different) patents and approximately 170 scientific publications in refereed journals or conference proceedings with referee procedure to his name. He has published seven books, either as editor or author.

Choice Review
This two-part volume discusses the worldwide distribution of biomass and details bioprocessing technologies via case studies. Part 1 is appropriate for general readers or students without a technical background; part 2 requires a significant organic chemistry/engineering background. The authors show that both the capacity and technology exist to regain the primacy of biomass for energy, fuels, and chemicals in a post-fossil-fuel economy. The authors suggest a future in which biomass is optimally managed to meet those needs, while alluding to the challenges. The chapter on aviation fuels is particularly comprehensive in its coverage of engineering/chemistry basics and algae/bio-oil production and processing. The chapter on the use of crops to produce ethanol is extremely detailed in processing data and life cycle analysis. Other chapters discuss wood and pulp/paper processing, and using microorganisms to transform organic wastes into useful chemicals. A common theme is that integrated facilities incorporating energy/fuels generation with the production of chemicals, paper, wood products, and foods while minimizing effluents is the only realistic economic model. As with many edited works, complexity varies between chapters; some sections contain grammatical/typographic errors that affected fluidity of reading and occasionally understanding. Summing Up: Recommended. Upper-division undergraduates and graduate students in environmental/social sciences, engineering, agriculture, or forest products programs; researchers/faculty; professionals/practitioners. B.
