With corn stalks as basic materials,  livestock and poultry waste and other organic waste can be flexibly mixed togerther at a certain ratio.  This project can consume about 33,000 tons corn stalks annually, or the same  amount of other organic waste, and consume livestock and poultry manure 0.4  million tons. By the consumption, 14.6 million m3 of biogas, 35,000 tons of  organic fertilizer and 0.92 million tons of industrial liquid carbon dioxide  can be output annually, and 7.3 million m3 biogas can be purified.    The main body of the project includes 8 units of 5,000 m3 of anaerobic  fermentation tank and ancillary works, car filling stations, gas stations and  gas transmission and distribution network as corresponding supporting  projects. The project consists of four parts of systems which are raw  material supporting system, biogas transformation and purification system,  biogas slurry & fertilizer conversion system and energy station  distributed in villages or towns and gas pipeline network system.
