On March 25, the groundbreaking and pile foundation commencement ceremony was grandly held for China's first closed-loop giant reed (Arundo donax) biomass green methanol integrated project with a total investment of 1.2 billion yuan—the Biomass Energy Integrated Polygeneration 100,000-ton/year Green Methanol Project of Tianjin Saihong Environmental Engineering Co., Ltd.—at the Dagang Petrochemical Industrial Park in Tianjin Binhai New Area. This project is another major benchmark in the green zero-carbon circular economy field laid out by Ruihengmao Group following the landing of the Tianjin Sludge Harmless Treatment and Resource Utilization Demonstration Base in 2020. With its "three-zero" green advantages—zero fossil energy consumption, zero fresh water consumption, and zero solid waste, liquid waste, and hazardous gas emissions—it has become a distinctive demonstration project in the Beijing-Tianjin-Hebei region, injecting strong momentum into the transformation and upgrading of the regional energy structure.

At the ceremony site, Tianjin Ruihengmao New Energy Co., Ltd. showcased the progress of the giant reed spring planting in real time via a live connection. On that day, the improved planting of 30,000 mu of giant reed was fully launched, and the footage showed mechanized operations proceeding in an orderly manner at the planting base. The relevant person in charge introduced that this year, with the Tianjin-Hebei-Shandong region as the core, efforts will be made to build a complete giant reed raw material supply system, simultaneously advance the improvement of 80,000 mu of saline-alkali land, implement 30,000 mu of giant reed planting, and build a seedling base with an annual capacity of 200 million plants, thereby ensuring the stability and compliance of raw material supply from the source and providing support for the long-term operation of the project.

Han Xiaoli, Deputy General Manager of the Certification and Evaluation Center of China Testing & Certification International Group Co., Ltd., released the project's greenhouse gas emission assessment results on site, providing authoritative endorsement for the project's carbon reduction benefits. She pointed out that, on the premise of fully capturing and utilizing all green carbon dioxide by-products to offset carbon emissions, the project has successfully achieved negative carbon emissions. This achievement not only demonstrates the project's benchmark and leading value within the industry, but also provides replicable practical experience for China's biomass energy projects to achieve low-carbon development. According to estimates, after the project is put into operation, it can reduce carbon dioxide emissions by 300,000 tons per year, with significant ecological benefits.

At the on-site signing session, Tianjin Saihong Environmental Engineering Co., Ltd. signed cooperation agreements with financial institutions including Tianjin Binhai OTC Market Co., Ltd. and the Tianjin Nankai Sub-branch of Agricultural Bank of China, further consolidating the project's funding guarantee, broadening financing channels, and laying a solid financial foundation for the project's comprehensive construction and steady progress. Co-organizers including the International Green Economy Association, the Tianjin Environmental Governance Industry Chamber of Commerce, and Tianjin Ruihengmao Technology Development Group Co., Ltd., as well as numerous strategic partners such as the Shipping New Energy and Environment Special Committee of the China Shipowners' Association and the Tianjin Green Methanol Alliance and Service Platform, jointly witnessed the signing. All parties will work together to safeguard the project's implementation and construction.

Wang Hongkun, General Manager of Tianjin Saihong Environmental Engineering Co., Ltd., the project developer, introduced that the project uses the polyploid giant reed "Lüzhou No. 1" carefully cultivated by Ruihengmao Group as its core raw material, successfully breaking through the bottlenecks of existing gasification technology and the economic challenges of biomass raw materials, and building a full-chain closed-loop system. Moreover, the production process uses not a single ton of fossil energy and consumes not a single ton of fresh surface water, with zero solid waste, zero liquid waste, and zero hazardous gas emissions, truly achieving two-way empowerment of ecological and economic benefits. Wang Hongkun disclosed that the project's preliminary preparations have been fully completed, with key links such as the feasibility study, final compilation of the process package, and HAZOP analysis all finished, long-cycle equipment procurement contracts smoothly signed, and the GHG report compilation successfully concluded. The simultaneously advanced spring planting of 30,000 mu of giant reed is proceeding in an orderly manner, laying a solid foundation for the project's smooth commissioning in May 2027. It is reported that "Lüzhou No. 1" giant reed can grow vigorously in saline-alkali land with a salt content of up to 6‰, can be harvested continuously for 20 years after a single planting, has a calorific value of 3,900-4,400 kcal/kg, and contains more than 86% cellulose, hemicellulose, and lignin, making it an ideal green energy raw material.

Lin Hongxin, President of the Tianjin Environmental Governance Industry Chamber of Commerce and Chairman of Ruihengmao Group, stated that the biomass green methanol project commencing construction this time carries the important mission of promoting zero-carbon park construction and serving the national "dual carbon" goals, and is a key step in Ruihengmao Group's industrial upgrading. He introduced that Ruihengmao Group has established a clear industrial development path: in the Industry 1.0 stage, it formed a path to obtain biomass raw materials at the lowest cost through the resource utilization of "water, sludge, and fertilizer," which has been incorporated into the National Science and Technology Major Project for Comprehensive Environmental Governance in the Beijing-Tianjin-Hebei region and will be comprehensively advanced in some regions this year; in the Industry 2.0 stage, it completed the transition from biomass pellet fuel to green methanol fuel, successfully entering the future energy field prioritized for development during the "15th Five-Year Plan" period; in the Industry 3.0 stage, it will focus on creating an integrated bamboo fiber-methanol model to further enhance product added value and the company's value-creation capability. Speaking of the corporate mission, he pointed out that Ruihengmao has always adhered to the core mission of "resource utilization of organic solid waste, improving saline-alkali land to plant the polyploid giant reed 'Lüzhou No. 1,' producing biomass energy and new materials, replacing fossil energy, and helping to realize a 'zero-waste city,' 'lucid waters and lush mountains,' and the 'dual carbon goals.'" Through the implementation path of "product industrialization, industrial ecologicalization, ecological closed-looping, and closed-loop intelligentization," it will steadily implement its ten-year plan. By 2035, the Group will complete the improvement of 20 million mu of saline-alkali land, achieve an annual disposal of 50 million tons of organic solid waste, produce 20 million tons of organic fertilizer, and produce 80 million to 100 million tons of giant reed raw materials per year, supporting the production of 30 million tons of pulp and green methanol, and achieving the goal of reducing carbon emissions by 300 million tons annually.

Deng Jihai, Executive President of the International Green Economy Association, pointed out that the project is not only a vivid practice of Tianjin's green and low-carbon development, but also a major breakthrough in the field of efficient utilization of biomass energy in China, providing a replicable and promotable demonstration model for the development of the biomass energy industry nationwide and even globally. Deng Jihai emphasized that green methanol, as a green fuel prioritized for development during the "15th Five-Year Plan" period, has become an important direction for the development of new quality productive forces in the energy field. It can effectively replace coal, safeguard energy security, help reduce carbon emissions, and promote green development. Relevant national departments have also issued multiple policies to promote the large-scale development of the green methanol industry, providing solid policy support and broad market space for the project's subsequent promotion and replication.

In the future, Saihong Environment will take this groundbreaking as a new starting point, adhere to the construction philosophy of high standards, high efficiency, and high quality, steadily advance project implementation, and strive to complete construction as soon as possible. After the project is implemented, it will further improve China's circular economy industrial chain and achieve deep synergy across the three major fields of ecological restoration, green energy, and resource recycling. The entire industrial chain is expected to reduce carbon emissions by 900,000 tons, directly provide 170 jobs, and indirectly drive more than 1,000 surrounding jobs. At the same time, it will co-produce 64 million kWh of green electricity, 200,000 tons of green steam, 500,000 tons of green industrial gas, and 200,000 tons of organic fertilizer, injecting strong vitality into the green economy of the Beijing-Tianjin-Hebei region and contributing referable Chinese wisdom and Chinese solutions to the global net-zero goal.
