By the end of 2007, China has 24 million digesters with annual production of 8.5 billion m3 biogas. The government invested 5 billion Euro to develop the markets and technologies. 4000 biogas engineering projects planed for larg-scale plants too.
China will be the biggest market worldwide for biogas plants and small digesters.
15 to 20 percent of the population will be served with biogas.
These are some results of a new updated study by helmut kaiser consultancy

A importend reason for anaerobic digestion beside of generating energy , is that methane is a major greenhouse gas, second to carbon dioxide in amount generated, but with a global warming potential 22 times that of carbon dioxide. Using biogas not only removes polluting wastes, but also mitigates global warming.
Biogas methane shall also be used as fuel for vehicles, and is the cleanest biofuel available. There are development projects in communities financed by the goverment. The major problem is still the lack of technical know how for running and maintaining the biogas digester on small scale but more on large scale plants.
A comprehensive ecological tax reform law is planed to encourage widespread adoption of biogas technologies in china.
To maximise the benefits of biogas as energy, China also needs advanced technologies to purify and compress methane and to build new engines that use methane effectively and efficiently, to run cars as well as farm machinery and others.
