Environmental Protection

2017 was declared the Year of Ecology in Russia and Severstal reiterated its commitment to reducing the environmental impact of its assets.

An automated gas-monitoring system was installed to control and reduce air pollution from sulphur dioxide. The construction of the desulphurisation unit is in its pre-project phase. 

Severstal’s environmental department continued to study the mine’s impact on surrounding water bodies to develop initiatives that will reduce its impact.


The installation of a natural biological treatment system at the mine’s waste water storage plant is ongoing. Different species of plants are cultivated to reduce the concentration of harmful substances in the water as well and reduce dust on land. This has already reduced the concentration of polluting substances by 15–25%.


The thermoelectric plant utilises coalmine methane from the Vorkutinskaya mine, helping to minimise waste.


The new blast furnace #2 uses a combined gas cleaning system that reduces emissions to the atmosphere. The gas treatment line is being reconstructed to improve waste water treatment. The construction of a new waste dump is planned to start following a period of public consultation.

Ongoing research into ways to reduce the mine’s environmental impact on nearby water bodies.


The installation of a natural biological treatment system at the waste water storage will be ongoing.


The reconstruction of #4 coke battery will be completed in 2018. The aim of the project is to improve the quality of coke and reduce emissions of coke dust.

A number of energy projects are planned to increase the plant’s self-sufficiency and reduce power consumption.
