Fringe Friday: GreenIron Furnaces To Recycle Oxidized Metals

Sometimes our editors find items that are not exactly "heat treat" but do deal with interesting developments in one of our key markets: aerospace, automotive, medical, energy, or general manufacturing. To celebrate getting to the “fringe” of the weekend, Heat Treat Today presents today’s Heat Treat Fringe Friday press release: an agreement between GreenIron and SECO/WARWICK for a reduction furnace line will allow for the recycling of oxidized metals without emissions.

Swedish company GreenIron H2 AB has signed an agreement with the SECO/WARWICK Group, a global manufacturer of metal treatment equipment, for the delivery of a series of furnaces for fossil-free metal production including ore, residuals, and waste recycling.

"We feel that our partnership is a great foundation for rapid growth and a positive impact on emissions and climate change," commented Edward Murray, CEO of GreenIron. "GreenIron has high ambitions in regard to CO₂ reduction, starting with the first furnace, delivered by SECO/WARWICK, and the subsequent first shipment of commercial fossil-free iron in 2023."

The furnaces ordered by GreenIron will be used to recycle oxidized metals without emissions. They will therefore directly contribute to CO₂ emission reduction as each furnace has the capacity to reduce emissions by 56.000 metric tons/yr. The technology will help many enterprises implement "green" solutions and function in harmony with the natural environment.

The metals are extracted from ore or recycled without the release of fossil gases. Iron oxide (magnetite, hematite, wustite) is converted to pure iron by the hydrogen reduction process. In traditional technology, this process takes place in coke furnaces, which results in CO₂ emissions. In the GreenIron furnaces, CO₂ emissions are zero.

“It is also an opportunity for SECO/WARWICK, because together with GreenIron we are creating a production line of completely new furnaces. For the first time, we are working closely with an external partner with technology that comes from outside of our organization,” adds Sławomir Woźniak, CEO of SECO/WARWICK Group.

Reduction furnaces will be available to companies throughout the entire lifespan of iron and other metals – including mining, steelmaking, milling stations, foundries, metal workshops and heavy ashes from incinerators.
