Bioenergy production from wastes and wastewaters in China


Keywords: , , , ,

China is investing billions of US dollars annually on renewable energy production. China is leading the world not only in wind and solar energy production, but also in harnessing bioenergy from wastes and wastewater. The recovered bioenergy, mostly in the form of purified methane, is either converted to electricity, or for uses as industrial raw material, or as a supplement of natural gas for vehicle fuel. In this poster, a number of case studies in China on this subject will be presented. These are merely a few selected examples of thousands of similar installations all over China, many of which treating daily 5,000-10,000 tons of wastewater with ~10,000 mg-COD/l (in particular from starch, brewery and distillery industries). Case studies of treating rural household wastes and livestock wastes will also be presented. In one particular case, the treatment facility processes manure collected from several farms (within a 10-km radius) with a total capacity of 13 million chickens; this zero-discharge treatment facility was the first in China earning carbon credit (>US$1.2M annually) with certification from the World Bank. More details will be discussed.
