Biogas from Waste and Renewable Resources (eBook)

Dieter Deublein is a professor at the Munich University of Applied Sciences, leading applied research and development in the field of biology and biogas production in close collaboration witht the industry. Prior to this, he gained his broad and profound knowledge, especially in process engineering, during 12 years of experience in industry, leading worldwide construction projects for industrial plants processing natural substances. Professor Deublein has many practice-oriented publications sharing his practical experiences and 10 patent applications to his name. Angelika Steinhauser studied biotechnology at the Munich University of Technology - Weihenstephan - and has been leading projects in research and development in a large multinational company for the past five years. Driven by her strong interest in the potential for biogas production, especially in Asia, she has been gathering information in her current hometown of Singapore on existing plants and current practices in emerging and developed markets so as to understand future opportunities. She has included her knowledge and investigations in this book.
