This book, based on extensive field work and research, examines the status quo of China's biomass energy developments in the renewable energy sector by conducting three representative case studies of biogas projects in China with different feed-in stocks and scales. By integrating material flow management (MFM) concepts into the projects' development and implementation, the author has applied SWOT analysis to each of the enlisted case study, to determine what are the strengths, weakness, opportunities and threats for the biogas project development and relevant policy in China.
