Household biogas digesters can improve sanitary conditions by preventing the breeding of flies and mosquitoes in untreated manure in hot weather. The Improved living conditions for local people are beneficial for people’s physical quality. Biogas lamps, biogas rice cookers, and biogas stoves would directly improve the living and educational conditions for rural population, especially for women and children by saving time to collect firewood for cooking. Besides, safer organic fertilizer, slurry and sludge are provided from household digesters, thus will result in agricultural production increase and chemical fertilizer consumption decline. This is also beneficial for the financial situation of the families in a CO2 neutral way and at the same time it will protect the environment.
At present, Detong have two kinds of the household biogas digesters: The soft biogas digester (Membrane bag and Half Membrane cover) and FRP household biogas digester. Please refer to the following pictures:
Domestic biogas plants convert livestock manure and feces into Biogas and Biogas slurry & Residue. The annual biogas production capacity of a running household digester in China averages 300‐438 m3 and the biogas production of a same running digester in Africa or South Asia would reach or even exceed the figure above mentioned due to its warmer climate. Even the popularizing rate of household biogas digester in China is still not very high due to the huge population, millions of household biogas digesters have been and being installed. The application of household digesters in China has improved Chinese people’s life significantly in a sustainable and environmentally friendly way.
