The first scientific developments in the field of biogas technologies were made in Russia more than 70 years ago. Since the 50th years one of the main directions was the anaerobic processing of activated sludge and sediments of urban wastewater. This method attracted attention in connection with the idea of obtaining biogas mainly from the manure of farm animals. Thanks to this in the middle of 50th years a number of pilot plants for biogas production were built in Zaporozhia, Belorussian, Georgian, Moldavian branches of All-Russian Institute of Agriculture Electrification, and also in Ekaterinburg. However, the operating experience of these installations was insignificant - one - two seasons. The problem of obtaining and using biogas is given great attention abroad. In a short time, in many countries around the world a whole industry for the production of biogas has emerged. The leader in the development of biogas industry is China. Since the middle of 1970, the National Program for the production of biogas from livestock wastes has been operating in this country. Currently, there are 10 million farm bioreactors. In addition, 40 000 biogas stations, 24 000 biogas treatment plants operate in China, which provides operation of 190 power plants.
