SDIC Bioenergy (Tieling) Co., Ltd. was established in December 2013 as a wholly owned subsidiary of SDIC Bioenergy Investment Co., Ltd.—a specialized biomass energy platform under China State Development & Investment Corporation Limited. Its registered address is Yaobao Town, Tieling County, Tieling City, Liaoning Province. Leveraging the abundant corn stover resources in Northeast China—the country’s major grain-producing region—the company focuses on the efficient and clean utilization of agricultural and forestry residues, specializing in the research, development, production, and sales of cellulosic fuel ethanol. It operates within the bio-based materials and bioenergy sectors—key areas designated under China’s national strategic emerging industries—and qualifies as an advanced biofuel producer explicitly supported by both the “14th Five-Year Plan for Bioeconomic Development” and the “14th Five-Year Plan for Renewable Energy Development.”  

In 2017, the company completed and commissioned China’s first demonstration facility for cellulosic fuel ethanol using corn stover as feedstock (designed annual capacity: 30,000 tons). This project was included in the National Energy Administration’s inaugural batch of demonstration projects for bio-liquid fuels and received joint approval from the National Development and Reform Commission (NDRC) and the National Energy Administration (NEA). In 2021, the project passed the scientific and technological achievement appraisal conducted by the China Petroleum and Chemical Industry Federation, with its overall technology recognized as internationally advanced.  

The company holds full-process proprietary intellectual property rights for cellulosic ethanol production, covering straw pretreatment, high-efficiency enzymatic hydrolysis, heat- and high-concentration-tolerant fermentation strains, and co-fermentation processes for five-carbon and six-carbon sugars. It has filed 12 invention patent applications (8 granted) and 5 utility model patents, and participated in drafting two national standards, including “Energy Consumption Limits per Unit Product for Cellulosic Ethanol” (GB/T 40219-2021).  

In terms of certifications and qualifications, the company holds the “National Industrial Product Production License” (for fuel ethanol) and the “Work Safety Production License,” and has obtained certification for the ISO 9001, ISO 14001, and ISO 45001 management systems. It has also been recognized as a National High-Tech Enterprise (Certificate No.: GR202221000286). Its fuel ethanol products comply with the national standard GB/T 22517.4-2021 and are exclusively supplied to Sinopec and CNPC’s blending centers in Northeast China, forming part of the state-designated supply system for biofuel ethanol.  

Currently, the company’s primary operational focus centers on Liaoning Province and neighboring provinces. Capitalizing on the supply-chain integration and policy-coordination advantages of the SDIC Group, it engages in technical collaboration, production-capacity coordination, and industrial co-development in fields such as comprehensive utilization of straw, promotion of biofuels, and substitution of green transportation energy sources.
