China’s first 100,000-ton/year closed-loop green methanol project using moso bamboo biomass was launched on March 25. Located in the Dagang Petrochemical Industrial Park in Tianjin Binhai New Area, this project, which represents China’s first integrated closed-loop green methanol production facility based on moso bamboo biomass, has a total investment of 1.2 billion yuan. It is part of the biomass energy integration and multi-product generation project carried out by Tianjin Saihong Environmental Engineering Co., Ltd., with a production capacity of 100,000 tons of green methanol per year. Wang Hongkun, general manager of Saihong Environment, said that the project uses \"Luzhou No. 1\", a polyploid phragmites cultivated with care by Tianjin Ruihengmao Group, as its core raw material. It successfully overcomes the existing bottlenecks in gasification technology as well as the economic challenges associated with biomass raw materials, thereby creating a closed-loop system for the entire production process. During this process, no 1 ton of fossil energy is used, nor is 1 ton of fresh surface water consumed; there is zero waste in solid form, zero liquid waste, and zero emissions of harmful gases. At present, the preliminary preparation work for the project has been fully completed. Key tasks such as feasibility studies, the final formulation of the process package, and HAZOP analyses have all been finished. Contracts for the procurement of long-term-use equipment were successfully signed, and the preparation of the GHG report was brought to a successful conclusion. The spring sowing of 30,000 mu of Phragmites australis is also progressing in an orderly manner. The project is scheduled to begin operations in May 2027. According to Wang Hongkun, the \"Oasis No.1\" phragmites can thrive in saline-alkali soil with a salt content of up to 6‰. It can be harvested continuously for 20 years after a single planting, and its calorific value ranges from 3,900 to 4,400 kcal/kg. The contents of cellulose, hemicellulose, and lignin in it exceed 86%, making it an ideal raw material for green energy.
