On May 16th, as the industrial exhaust gas of Shougang Jingtang United Iron & Steel Co., Ltd. experiences a magical journey, the clear, 99.5% of qualified and reliable ethanol products were produced from the distillation tower. The first set of project of producing ethanol fuel with 45,000 tons of industrial exhaust gas per year through biological fermentation method in the world of Shougang Lanza Co., Ltd. was successfully debugged in Shougang Jingtang United Iron & Steel Co., Ltd. on the first try.

 The successful commissioning marked the revolutionary breakthrough made by Shougang Langze Co., Ltd in the field of bio-clean energy. This independent innovation technology is currently the world's only child and has created many world records. At present, it has applied for more than 20 patents. The project will be the leader in the development of new energy.

Turning the industrial exhaust gas into clean energy through biotechnology is a worldwide problem that involves many difficulties in many fields. Before that, there was no precedent for industrial application in the world. In 2011, Shougang Group, Tang Ming Group in New Zealand and LanzaTech in the United States worked together to found Shougang Lanza Co., Ltd. In 2012, the only full-process pilot plant with 300 tons of industrial exhaust gas per year in the world was built in Shougang Jingtang United Iron & Steel Co., Ltd. Through many pilot tests, the scientific and technical R&D personnel of Shougang Lanza Co., Ltd. continuously promote scientific and technological innovation, optimize technological process, successfully complete the full-process technology integration system and lay a solid foundation for the construction of the first commercial project. As the star project of Caofeidian industrial park, with the support of two strategic investors: Shougang Fund and Shanghai Dehui Group, Shougang Lanza Co., Ltd. invested RMB 350 million and successfully built the first set of commercial device of producing clean energy with 45,000 tons of industrial exhaust gas per year through biological fermentation method in the world in December 2017, and the equipment localization rate is over 97%.

Industrial exhaust gas is fermented by microorganisms in large fermentation tanks, and it is converted from gaseous to clean energy in a liquid state. This makes the use of high-valued fuel ethanol, natural gas, and high-protein feeds to increase the use of resources that pollute the environment. After persistence and full preparation, Shougang Lanza Co., Ltd. finally turns the seemingly unrealizable technology into reality. With the arduous efforts of the management team, technical R&D team and engineering team, the company overcomes many technical difficulties, masters the leading scientific and technological innovation technologies in the world, officially produces qualified ethanol liquid fuel with 99.5% of concentration that meets the national standards and realizes green low carbon, circular economy and sustainable development.

The successful debugging of the first project of producing ethanol fuel with 45,000 tons of industrial exhaust gas per year through biological fermentation method in the world of Shougang Lanza Co., Ltd. is of landmark significance to the exhaust gas treatment of industrial companies and the traditional ethanol fuel production industries. Each year, about 45,000 tons of ethanol fuel, 7,650 tons of protein feed and 3.3 million cubic meters of compressed natural gas will be produced. This project reduces the pollutant emission caused by the combustion of industrial exhaust gas and produces ethanol fuel, providing a new way for the high-valued utilization of industrial exhaust gas, is conducive to improving the comprehensive utilization efficiency and development of circular economy of industrial companies and finds a new technical way for the diversification of raw materials for Chinese ethanol fuel production.
