On November 8, 2024, the groundbreaking ceremony for the project aimed at using CO2-containing industrial waste gas to synthesize anhydrous ethanol, developed independently by Beijing Shougang Langze Technology Co., Ltd. (hereinafter referred to as “Shougang Langze”), was held on the premises of its production facility in Hebei Province – Hebei Shoulang New Energy Technology Co., Ltd. in Caofeidian District, Tangshan City, Hebei Province (hereinafter referred to as “Hebei Shoulang”). This project was included in the **National Development and Reform Commission’s List of Demonstration Projects for Green and Low-Carbon Advanced Technologies (First Batch). It is the world’s first demonstration project on a scale of 10,000 tons that uses carbon dioxide-containing industrial exhaust gases from steel mills to produce anhydrous ethanol through biological fermentation technology. 　　It is reported that this project utilizes the gas-based continuous biorementation technology independently developed by Shougang Langze. Using carbon dioxide-containing coke oven and converter gas from Shougang Jingtan as raw materials, it produces anhydrous ethanol and new types of feed proteins through processes such as gas pretreatment, fermentation, and distillation for dehydration. Once completed and put into operation, the project will be able to produce 15,000 tons of anhydrous ethanol, 750 tons of protein feed, and 2 million cubic meters of biogas per year, with annual sales revenue estimated at 120 million yuan. 　　In recent years, with the care and support of Shougang Group, Shougang Jingtang, and various other parties involved, Shougang Langze has adhered to the strategy of \"one leadership and two integrations\" – that is, taking technological innovation as the driving force to achieve integration between technological innovation and management innovation, as well as between such innovations and business model innovations. Focusing on green development, high quality, and sustainable growth, and relying on an innovation framework that includes \"strain research – pilot-scale testing – industrial application – industrial promotion\", the company has overcome numerous technical barriers, successfully streamlined the entire production process, and achieved significant technological breakthroughs in the resource utilization and large-scale application of CO2. This technology is at the international forefront, further solidifying Shougang Langze’s leading position in the fields of biomanufacturing and CCUS (carbon capture, utilization, and storage technologies). 　　Turning industrial exhaust gases into valuable resources yields significant carbon reduction benefits and offers broad market prospects. This technology can directly consume approximately 0.5 tons of carbon dioxide per ton of ethanol produced, which is in line with the development goals of the **\"dual carbon\" strategy. It can be widely applied in industries such as steel manufacturing, coking, and petroleum refining, and will serve as a good example for the development of a green, low-carbon circular economy in these industrial sectors.
