Key environmental indicators
Sustainable management of water resources
High recycling rate
Energy efficient production
NLMK Group has invested about $1.3 billion in environmental projects since 2000. Despite almost doubling production and becoming the largest steelmaker in Russia, NLMK was able to significantly reduce its environmental impact by introducing state-of-the-art technology and working hard to upgrade equipment.
NLMK Group environmental investment, 2001-2020.
NLMK Group has achieved an ongoing reduction in its air emissions. In 2020 the Group’s emission rate was 19.8 kg per tonne of steel.
This was possible thanks to a mix of management initiatives and capex projects: upgrades of production units, installation of dust and gas-cleaning units, installation and upgrade of filter equipment, introduction of immobilization and waste recovery technologies.
Decrease in NLMK Group emissions (kg/t of steel), 2005-2020.
NLMK Group is among the industry leaders when it comes to efficient water consumption and minimal discharges in its home regions, thanks to the advanced environmental technologies the Company employs.
Specific water consumption (per tonne of steel) has been consistently reduced and in 2020 reached 5.1 m3/t, which is below the BAT level of 7.0 m3 /t.
The share of recycled water supply in NLMK Group is at a consistently high level of 97%. In 2020, a five-year low of natural water consumption was reached, thanks to operational measures to control water consumption.
In 2020, NLMK Lipetsk implemented an investment project to upgrade local wastewater treatment facilities with investment amounting to RUB 118 million. Over the last five years, the volume of water disposal at the Lipetsk site was reduced by 4.2 million m3 (-34%). Over the last 40 years, annual withdrawal of fresh water from the Voronezh River by the Group’s core site in Lipetsk has been reduced nine-fold.
Decrease in NLMK Group water consumption (m³/t of steel), 2005-2020.
The use of modern technologies for recycling secondary resources, as well as the implementation of various recycling initiatives, enable efficient use of secondary resources. In 2020, 99% of iron-containing raw materials was recycled at NLMK Group companies, excluding mining waste.
In 2020, NLMK Lipetsk built a BF slag processing complex in place of a slag dump that had been accumulating since the 1970s. Close to 6 million tonnes of various materials were processed and more than 300,000 tonnes of iron were fed back into steel production in the course of the project.
Thanks to this project, 25 hectares of land were reclaimed thus avoiding the emission of 85,000 tonnes of greenhouse gases.
Recycling of secondary iron-containing raw materials, 2016-2020.
