NLMK Group Begins Testing Unique Environmental Facility in Lipetsk
10/27/2014 - NLMK Group has started hot testing of a unique environmental complex: a biochemical waste water treatment facility at the coke and chemical operations of its Lipetsk production site.
Total investment in the project which was implemented as part of NLMK’s Environmental Programme 2020 exceed RUB 2 billion.
From 2009, all industrial storm and waste water at the Lipetsk production site is contained in a closed-loop water cycle with multistage treatment to enable it to be reused in technological production processes. The new 160 m³/hour facility was designed using the best available technologies, and will provide a twenty-fold improvement in the quality of treatment of coke and chemical operations waste water for reuse in the closed-loop water cycle.
Sergey Filatov, NLMK managing director, said: “NLMK Group’s Lipetsk production site has achieved unprecedented results in the course of implementing the previous stages of its Environmental Programme: specific air emissions have been halved since 2000, while steel production has increased by 51%; and waste water discharge has been completely halted. But we are not going to stop at that and are continuing our ongoing efforts to reduce the company’s environmental footprint as part of NLMK’s Environmental Programme 2020. Our goal is to become the industry leaders in environmental efficiency. This project is yet another step towards achieving this goal.”
The facility employs a custom technology developed by Russian scientists for deep biochemical water purification from phenols, rhodanides, ammoniacal nitrogen and its oxides (nitrites and nitrates) in one stage, whilst the previous technology required several stages. Elimination of these obsolete stages allows for up to 95% waste water purification from nitrites and nitrates.
All infrastructure and utilities were installed above ground on an isolated concrete area equipped with a rain, melt and drain water collector, preventing any chance of groundwater pollution in the event of a containment failure.
About Environmental Programme 2020
In May 2014, NLMK Group announced the launch of the third stage of its environmental programme, covering the period up to 2020 (Environmental Programme 2020). This programme is part of the Group’s development strategy and investment programme. It is aimed at further minimizing our environmental footprint and achieving the best possible environmental standards in global steel production.
Investment in environmental initiatives and projects at NLMK Group companies will total RUB 10.6 billion. Most of the funds will be invested at NLMK’s Lipetsk production site.
Environmental Programme 2020 will ensure:
· compliance with all environmental standards by all enterprises of the Group;
· reduction in specific emissions at NLMK’s Russian sites from 22.6 to 19.4 kg per metric ton of steel to comply with the level of the best available technologies in the global steel industry;
· zero waste water discharge at all Group sites;
· increase in waste recycling from 5% to 25%;
· complete elimination of waste accumulated over previous years (in particular, the slag heap formed at the Lipetsk site over the last 80 years, and the sludge dump at NSMMZ (Revda) that has been there for over 40 years).
Results of NLMK’s Environmental Programme 2007–2012 (Stage 2)
During Stage 2 of its Environmental Programme (from 2007 to 2012), the Group invested over RUB 21 billion in environmental projects. As a result, specific air emissions decreased by 40% (from 37.5 to 22.6 kg per tonne of steel), and waste water discharge was reduced by 54 times (from 1.08 to 0.02 kg/t). Waste water discharge at the Lipetsk site was completely eliminated in mid-2009.
