In Belgium, ArcelorMittal, the world’s leading steel and mining company, LanzaTech, Inc., the carbon recycling company, and Primetals Technologies Austria GmbH, a leading technology and service provider to the iron and steel industry have entered into a Letter of Intent (LoI) to construct Europe’s first-ever commercial-scale production facility to create ethanol from waste gases produced during the steelmaking process.

The 47 000 tonnes of ethanol per annum project, 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 percent of the carbon used in the chemistry of steelmaking leaves the process as carbon monoxide (CO). Currently, 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 carbon dioxide (CO2) is emitted. LanzaTech’s proprietary technology, however, recycles the waste gases and ferments them with a proprietary microbe to produce ethanol.
Two-phase flagship project
Construction of the EUR 87 million flagship pilot project, which will be located at ArcelorMittal’s steel plant in Ghent, Belgium, is anticipated to commence later this year, with ethanol production expected to start mid-2017. A total of EUR 10.2 million has been secured for the “Steelanol” project under the EU’s 2020 Horizon (H2020) programme for research and development.
Construction will be in two phases, with phase one providing an initial capacity of 16 000 tonnes of ethanol per annum by mid-2017 and phase two, which will be completed in 2018, bringing the total capacity to 47 000 tonnes per annum.
According to ArcelorMittal, the recycled carbon derived ethanol can cut greenhouse gas (GHG) emissions by over 80 per cent compared with conventional fossil fuels. It will predominantly be used in gasoline blending, but it can also be further processed into other products such as drop-in biojet fuel.
ArcelorMittal, which has been working on this project since 2011, has signed a long-term partnership agreement with LanzaTech. Hence, once construction of the Ghent flagship plant is complete and the commercial viability of the project is proven, the intention is to construct further plants across ArcelorMittal’s operations.
This partnership is an example of how we are looking at all potential opportunities to reduce CO2 emissions and support a transition to a lower carbon economy. Steel is produced through a chemical process that results in high levels of waste gases being emitted; this new technology will enable us to convert some of these waste gases into fuels that deliver significant environmental benefits when compared to conventional fossil fuels. It is an example of why our carbon footprint should be viewed on a life cycle analysis basis, given steel is 100 percent recyclable and the material impact we make on reducing the carbon footprint of our customers through product innovation, said Carl De Maré Vice President, Innovation, ArcelorMittal.
If scaled up to its full potential in Europe, the technology could enable the production of around 500 000 tonnes of ethanol a year.
ArcelorMittal and Primetals Technologies have consistently stayed on the cutting edge of innovation in the steel industry and have demonstrated their commitment to reducing their carbon emissions. We are tremendously excited to announce this partnership and our first production facility in Europe at a time when it is abundantly clear that we need all solutions and the commitment of large corporations, cities and countries around the world, to help us stay within our 2 degree carbon budget and keep fossil reserves in the ground, said Jennifer Holmgren, CEO of LanzaTech.
As the production of bioethanol is a new activity, ArcelorMittal intends to set up a dedicated company for the rollout of this technology with strategic financial partners. Financing will be sought from a number of different sources. Talks are currently taking place with potential equity and debt partners.
Primetals Technologies will be responsible for part of the engineering, automation, key equipment and commissioning.
We are excited to be a partner in this leap-frog project with LanzaTech and ArcelorMittal. Once in operation, it will become a game changer within the industry and a benchmark for low-carbon footprint steelmaking, said Karl Purkarthofer, Senior Vice President of Primetals Technologies.
