Abstract: China is a leading state in the research and application of Anaerobic Digestion Technologies (ADT) on the world specially in rural areas. For the current application, there are four main fields including the Treatment of Agricultural Waste (AWT), Industrial Organic Waste Waster (IOWT), Urban Waste Water and the Mud from Waster (UWMT), and Urban Solid Organic Disposals (USODT). Higher gas production, optimal design and combination of components for the AD system, and better integration in a District Ecological Circle for sustainable development have been achieved. The problems remain for ADT in China and the potentialities are analyzed. Suggestions for efficient application of ADT in China and the developing countries are proposed.
