On December 8, the Zhangye City Ecology and Environment Bureau published a public notice regarding the proposed approval decision for the environmental impact assessment document of the construction project. Project Name: Haijin’s Annual Production of 100,000 Tons of Green Bio-methanol Project – Approval Pending. Publication Date: December 8, 2025. Location of Construction: Circular Economy Demonstration Park, Zhangye Economic and Technological Development Zone. Constructor: Haijin (Zhangye) Biofuels Co., Ltd. Environmental Impact Assessment Agency: Western (Gansu) Ecological Environment Engineering Co., Ltd. Project Overview: This is a new construction project located in the Circular Economy Demonstration Park of Zhangye Economic and Technological Development Zone, covering an area of approximately 250 mu. The construction includes the establishment of key facilities such as a new biomass carbonization unit, a biomass gasification unit, a purification unit, a methanol synthesis unit, and a methanol distillation unit. Additionally, 12 sets of insulated combustion chambers (10 in use and 2 as backups), 12 sets of steam generators (10 in use and 2 as backups), as well as other auxiliary production facilities and equipment for water supply, power supply, environmental protection, etc., will be installed. Upon completion of the project, it will produce 100,000 tons of green methanol and 1,186.24 tons of fusel oils per year. The total investment for the project is 815,872,600 yuan, of which 14,898,000 yuan is allocated to environmental protection measures, accounting for 1.83% of the total investment. Using cow manure, natural gas, activated carbon, and other materials as raw materials, Longyuan (Zhangye) New Energy Development Co., Ltd. supplies green oxygen and green hydrogen to the plant site through pipelines to produce green methanol. This represents an innovative breakthrough in the utilization of biomass energy and environmentally friendly practices; it extends the industrial chain for the recycling of biomass resources and increases the added value of these products. The economic, social, and ecological benefits resulting from this approach far exceed those obtained by using cow manure as fuel directly. China National Chemical Fourth Modernization Construction Company signed a PC general contract for a 100,000-ton/year green bio-methanol project with Haijin (Zhangye) Biofuel Co., Ltd. Under the agreement, the company will provide turnkey contracting services for the entire project lifecycle, from design and procurement to construction. It will make use of its patented technologies in the field of green chemistry as well as digital management methods to ensure timely project completion and cost control, with the goal of creating a benchmark project for clean energy in the Northwest region.
