Agricultural waste is waste gas generated by agricultural production and agricultural product processing, such as straw, stumps, weeds, fallen leaves, fruit shells, vines, branches and other wastes. Agricultural waste can be fermented to produce biogas and become agricultural organic fertilizer. After a short period of fermentation, it can kill a large number of pathogenic bacteria and parasite eggs in human and animal feces, plant pests hidden in various straws, and various weed seeds, etc., and then put into the biogas pool for fermentation to produce biogas. This treatment method can not only provide biogas fuel, but also obtain high-quality organic fertilizer.
