Promote green steel transformation of enterprises

Earlier, LanzaTech, a leader in carbon capture technology, and Pruitt Metallurgical Technologies announced the signing of a new 10-year cooperation agreement to accelerate the deployment of integrated environmental solutions in the global steel industry.

LanzaTech, based in Skokie, Illinois, converts waste carbon into valuable materials such as sustainable fuels, textiles, packaging and other products. By utilizing a variety of waste materials,LanzaTech's technology platform enables future consumers to no longer rely on mineral materials in their daily lives. LanzaTech's goal is to challenge and change the way the world uses carbon, to achieve a new carbon circular economy where carbon is reused rather than wasted, the skies and oceans are kept clean, and pollution is a thing of the past.

Combination of strong and powerful forces

LanzaTech's commercial carbon cycle platform converts emissions from heavy industry, including the steel industry, into fuels and chemicals. With more than 60 years of experience in metallurgical production innovation, Pruitt Metallurgical Technology brings together many advanced technologies from its predecessor companies Mitsubishi Hitachi Steel Machinery Co., LTD., and Siemens Voestland Metallurgical Technology (founded in 1938). Today, Pruitt Metallurgical Technologies is one of the oldest international suppliers of new technologies exclusively for the steel industry.

Green steel solution

The new collaboration will further strengthen the joint strategy to drive a green transformation in the metallurgical industry: The focus of Pruitt Metallurgical Technologies is to combine innovative LanzaTech Carbon capture and utilization (CCU) technologies that can turn waste into value to provide a variety of green steel solutions. Under the previous agreement, the two companies cooperated on the integration and optimization of the process for converting steel mill emissions into commercial chemicals. Under the new 10-year agreement, Pruitt Metallurgical Technologies and LanzaTech will implement more projects using LanzaTech's carbon cycle technology in the global steel industry.

Emission conversion

The two companies have already worked together with ArcelorMittal, one of the world's leading steel companies, to apply LanzaTech's technology at ArcelorMittal's flagship plant in Ghent, Belgium. The ArcelorMittal Steelanol project will convert carbon emissions from blast furnaces into advanced ethanol that can be used to make sustainable fuels and other downstream products - a first for the European steel industry.

The commercial facility was completed in December 2022 and will be operational by the end of May 2023. Earlier this month, during METEC, the largest metallurgical exhibition in Dusseldorf,LanzaTech and Pruet Metallurgical Technologies jointly presented the first samples produced at the facility. When fully operational, the Steelanol facility will be able to reduce carbon emissions by 125,000 tons per year and produce 8,000 liters of advanced ethanol.

Net zero emissions target

"The steel industry's goal is to achieve net zero emissions by 2050 with breakthroughs in technology development at CCU," said Dr. Alexander Fleischanderl, Senior vice president of Metallurgical Technologies and Head of Green Steel at Pruitt. "Even if steel plants switch to new production methods,LanzaTech's solution can use a variety of different gases without any major changes in equipment or technology. If a steel mill decides to switch from its current carbon-intensive production route to a new process,LanzaTech's technology will still be suitable for the newly generated gases. This flexibility makes you very optimistic about the future of the industry."
