Can residue be used as biogas raw material?

1. After half a year's trial and error, qingbaijiang district Agricultural Development Bureau has mastered a brand-new technology. After technical treatment, the waste residue of Dior factory turned waste into treasure and was used as the raw material of biogas digester. The raw material has good and lasting gas production effect, and has the characteristics of economy, environmental protection and energy saving, which has been well received by users in the experimental area. At present, technology is basically mature. Once the project is started, it will solve 5000 tons of waste residue for enterprises every year. According to the annual consumption of 5 tons of 6m3 household biogas digesters, it can supply 1 0,000 biogas digesters, and each biogas digester can produce biogas 1.2 m3 per day, which can basically meet the daily energy consumption of every household. 2. In recent years, Xixia County, while accelerating the construction of rural biogas, has developed biogas by using wastes such as straw, edible fungus waste and dregs, and has embarked on a road of recycling.

Production of biogas from edible fungus waste. Xixia is a big county for producing edible fungi, which develops more than 30 million bags of edible fungi and Pleurotus nebrodensis every year, and a large amount of edible fungi waste is accumulated in rural areas. In order to solve this problem, Xixia County has invested more than 6,543,800 yuan to build large-scale centralized gas supply projects in Xiaozhai Village of Shijiehe Township, Wanying Village of Danshui Town, Sungou Village of Tianguan Township and Xuangou Village of Dinghe Town. Through fermentation and gasification.

Using waste residue to produce biogas. Wanxi Pharmaceutical Co., Ltd. is a well-known Chinese medicine pharmaceutical enterprise in Xixia County, and the dregs produced every year become the best raw materials for the development of biogas. Xixia County signed a long-term purchase contract with Wanxi Pharmaceutical Co., Ltd., taking Wanxi Pharmaceutical Co., Ltd. as the raw material base for centralized supply of biogas, and developing biogas with dregs, which digests 5000 tons of waste dregs every year, providing a stable gas source for farmers in Xixia County.
