The basic principle of organic fertilizer equipment technology is: the use of urban discharge of domestic combustible waste, crop waste straw, rice husks, forest products processing corner residues as raw materials, through the biomass gas generator unit device, the production of low calorific value combustible gas, for industrial production energy, heating energy and urban and rural residents living energy. The whole gas production process is closed, pollution-free and zero-emission. It is a new renewable clean energy project that is environmental protection and emission reduction and sustainable development, which is widely used in industrial production and civil life energy, and will effectively implement low-carbon economic operation. At present, the domestic and foreign waste treatment methods widely used are mainly sanitary landfill, composting and incineration through organic fertilizer production lines, etc. The proportion of these three main waste treatment methods is due to the geographical environment; The composition of garbage, the level of economic development and other factors vary. Due to the complex composition of municipal waste, and affected by the level of economic development, structure, natural conditions and traditional habits and other factors, the treatment of municipal waste in foreign countries is generally different with the national conditions, often a country in various regions also adopt different treatment methods, it is difficult to have a unified model, but ultimately are harmless, resource, reduction as the treatment goal.
