Air emission reduction projects

  • EVRAZ ZSMK

    EVRAZ ZSMK launched two dust removal units that use bag filters, replacing the outdated wet flue dust cleaning units. Two additional filtration units will be launched by the end of 2018. The new equipment will reduce dust emissions from the sinter plant by 22%. The four planned units will have a combined capacity to filter 900,000 cubic metres of air per hour and will eliminate more than 99% of impurities.

  • EVRAZ NTMK

    EVRAZ NTMK retrofitted its coke dry quenching plant using its own patented technology to purify secondary coke gases in fabric filters for later re-use in production. Previously, these secondary gases were flared into the atmosphere but now they are used as fuel. The project has helped to decrease the plant’s overall atmospheric emissions by 20%. The reduction in greenhouse gas emissions is equivalent to 40,000 tonnes of carbon dioxide.

  • EVRAZ ZSMK

    Since 2011, EVRAZ ZSMK has been implementing a programme to protect water resources that aims to gradually close the water cycle and minimise discharge volumes. In 2017, the programme helped to reduce the freshwater intake by 4.4 million cubic metres and the discharge into rivers by 3.4 million cubic metres of water per year.

  • Raspadskaya

    Since 2011, Raspadskaya has been implementing a programme to protect water resources by upgrading the equipment used to filter the water that it pumps out of mines and quarries. In 2017, the Raspadskaya-Koksovaya mine launched a water filtration unit that uses pressure-flotation technology with post-treatment of wastewater in a high-speed filtration and disinfection system. The Group has previously used this technology at the Uskovskaya and Erunakovskaya-8 mines. Some of the filtered water is re-used in the production cycle and the rest is discharged into rivers in compliance with all environmental standards.
