During the period of "the Tenth Five Year Plan", "the Eleventh Five Year Plan" and "the Twelfth Five Year Plan", more than 30 billion yuan has been invested in the central budget to support the development of rural household biogas.
With the rapid development of urbanization and the changes of agricultural production mode, rural residential mode and farmers' energy use mode, the problems of normal use and sustainable development of rural household biogas are increasingly prominent, such as the lack of follow-up investment, the accelerated loss of biogas technicians, the loss of supporting services, many rural household biogas problems such as construction without use, idle waste and so on, which cannot continue to play their benefits , causing a waste of financial funds.
From decentralized household biogas to intensive treatment of livestock and poultry manure, the demand for large-scale biogas projects is growing day by day, especially the industrial bio natural gas with biogas purification as the direction is the focus of future development. There is almost no difference in fuel properties between the purified biogas and fossil natural gas, which has the characteristics of high value, high efficiency and easy access. It is the optimization and upgrading of rural household biogas and traditional biogas projects. In addition, biogas byproducts such as biogas slurry and biogas residue can be used to produce organic fertilizer, which can improve soil and fertility, increase crop yield and quality of agricultural products, accelerate the application of organic fertilizer, and replace chemical fertilizer, which is an important measure to promote the green development of agriculture. Accelerating the industrialization of biological natural gas will play a positive role in realizing circular agriculture, promoting the utilization of livestock and poultry manure resources, harnessing the rural living environment, increasing the consumption of renewable energy, reducing the dependence of natural gas on foreign countries, and solving the problem of clean heating in winter in northern China.
