20 years ago, Han Bao agricultural and animal husbandry chairman Xiuxiong Chen began to try to produce biogas by animal excrements. He use anaerobic to transform methane to gas; use gas to generate electric power to help the piglets keeping warm in the winter through biogas. In animal husbandry, it’s unavoidable to produce waste in the feeding process; it often discharged into the river and caused large pollution to environment. It is expected to promote pig farmers to convert pig manure into a wide range of energy reuse and improve river water quality. Hanbo farm has wind power, solar panels and green biogas of green energy. This presentation provides information of curricular economy of Hanbo farm and detail of transformation, including machines, technics and experience.
