A major science and technology project was launched in Hohhot on August 11, focusing on the research and development of key technologies for converting agricultural and forestry residues into electronic-grade biomethane and super carbon materials.
The project is led by Inner Mongolia Huameng Kechuang Environmental Technology Co., Ltd., in collaboration with the Chengdu Biogas Research Institute of the Ministry of Agriculture and Rural Affairs, the Institute of Chemical Industry of Forest Products of the Chinese Academy of Forestry, Inner Mongolia Agricultural University, and Inner Mongolia Mengniu Biomass Energy Co., Ltd.. Chinese Academy of Engineering academician Jiang Jianchun serves as the project lead.
The initiative will focus on overcoming key challenges such as the directional construction of high-solid anaerobic fermentation methane-producing bacteria communities, standardized pretreatment of diverse biomass, and regulation of continuous high-solid fermentation. It also aims to develop low-energy continuous purification technology for producing electronic-grade methane.
A key milestone is the construction and stable operation of a thousand-ton biomethane demonstration line. This will establish a complete technological chain covering "raw material collection, storage, and transportation—pretreatment—high-solid anaerobic fermentation—purification and lifting—electronic-grade methane/super carbon material co-production—byproduct resource utilization."
The project is considered highly significant for enhancing the high-value utilization of agricultural and forestry residues, including straw, shrub branches, and livestock manure in rural and pastoral areas. Inner Mongolia has 173 million mu of arable land, with an annual collectable crop straw volume of about 48 million tons and a similarly large volume of livestock manure.
In 2026, the Inner Mongolia Autonomous Region's Department of Science and Technology launched this major project to address the currently low utilization of agricultural and forestry residues, insufficient efficiency and stability of high-solid anaerobic fermentation, and the low added value of biomethane.
The project is aligned with the national "dual carbon" strategy and the regional demand for resource and high-value utilization of agricultural and forestry residues. It aims to improve the ecological environment in rural and pastoral areas, upgrade the traditional biogas industry, and promote green agricultural development.
