LanzaTech is partnering with two companies in the metals businesses to build a nearly $97 million ethanol plant. This company news release says LanzaTech, ArcelorMittal a steel and mining company, and Primetals Technologies, in the iron and steel industry, will construct Europe’s first-ever commercial scale production facility to create bioethanol from waste gases produced during the steelmaking process. The resulting bioethanol can cut greenhouse gas emissions by over 80 per cent compared with conventional fossil fuels.
The 47,000 ton ethanol/annum project, sufficient to fuel half a million cars with ethanol blended gasoline, will demonstrate the added value of recycling waste streams, not only by reducing emissions at source, hence reducing ArcelorMittal’s direct carbon footprint, but by keeping fossil fuels in the ground through the production of commodity chemicals and fuels that would otherwise be made from oil.
Approximately 50 per cent of the carbon used in the chemistry of steelmaking leaves the process as carbon monoxide. Today, this waste gas stream is either flared or used to heat and power the steel mill. In either case, the carbon monoxide is combusted and the resulting CO2 is emitted. LanzaTech’s technology, however, recycles the waste gases and ferments them with a proprietary microbe to produce bioethanol. Every ton of bioethanol produced, displaces 5.2 barrels of gasoline as well as reducing ArcelorMittal’s CO2 emissions by 2.3 tons.
The project will be located at ArcelorMittal’s steel plant in Ghent, Belgium, is anticipated to commence later this year, with bioethanol production expected to start mid-2017.
