Outokumpu to Invest in Mercury Cleaning Technology at Tornio Plant
12/08/2014 - Outokumpu’s Tornio, Finland, plant has made continuous and long-time study to find an appropriate mercury cleaning technology to further reduce mercury emissions. A suitable technique has now been found and Outokumpu will invest in mercury cleaning technology at the Tornio plant.
Mercury is a foreign matter in stainless steel production: Outokumpu does not use mercury at all in its stainless steel production. Yet small amounts end up in the process in recycled steel which sometimes contains mercury.
Says Hannu Hautala, senior vice president, Outokumpu Tornio Business Line, commented: "We have found a method that is suitable for use in the Tornio melt shop process, and cleaning equipment have been piloted since last summer. The method proved to be effective and safe, and Outokumpu has made an investment decision of € 400,000 to acquire own installations."
On the basis of test results mercury cleaners further reduce Tornio plant mercury emissions significantly. In the stainless steel industry, Outokumpu is among the few producers who monitor mercury concentration and emissions with continuous measurements, and has acquired also a second continuous measuring device.
The long-term measurements of mercury concentration in vegetation indicate that the levels of mercury concentrations in Tornio and Haaparanta are same as elsewhere in the Nordic urban areas, and significantly lower than in Central Europe.
Outokumpu produces stainless steel with the lowest emissions in the world. "Over a period of 10 years we have implemented more than € 400 million in direct environment investments Group-wide, and have reduced our carbon footprint by 25%. The carbon footprint of the Outokumpu Kemi-Tornio supply chain is the smallest in the world compared to other stainless steel producers. In addition, Outokumpu makes use of more than 80% recycled material," said Hannu Hautala.
Vaasa Administrative Court recently announced its decision related to the 2012 submitted complaint against Northern Finland Regional State Administrative Agency’s decision to grant an environmental permit for Outokumpu’s Tornio plants. The decision was as expected, and the complaint was dismissed. Outokumpu Tornio site has a valid environmental permit which was renewed in the context of expansion of Outokumpu ferrochrome production in August 2012, after which the Swedish Sea and Water Authority submitted the now dismissed appeal.
