Environmental programme 2020

In May 2014 NLMK Group announced the start of the third stage of its Environmental Programme scheduled to run until 2020 (Environmental Programme 2020).

Part of the Group’s development strategy and investment programme, Environmental Programme 2020 is aimed at minimising environmental impact and achieving the industry’s best-in-class environmental performance.

The aim of the Environmental Programme 2020 is to:

  • Achieve compliance with all environmental regulations for all NLMK Group companies.
  • Reduce specific emissions by NLMK Group’s Russian operations from 22.6 to the steelmaking industry’s best available technology levels.
  • Achieve zero waste water at all production sites.
  • Increase the recycling rate from 5 to 25%.
  • Completely recycle accumulated waste including the slag heap in Lipetsk resulting from more than 80 years of operation and the 40-year-old sludge reservoir at NSMMZ in Revda.

Key projects within Environmental Programme 2020

NLMK Group’s total investment in environmental improvements and projects at its sites within Environmental Programme 2020 will exceed 10 billion rubles. The majority of the funds will be invested at the Lipetsk site.

AIR PROTECTION

2014. Novolipetsk

  • Build a new biological wastewater treatment system for the coke plant based on a unique process flow sheet developed by Russian researchers.

2015. Novolipetsk

  • Build a new blast furnace slag recycling facility to switch to water free slag cooling and reduce related hydrogen sulphide emissions by more than a factor of eight.
  • Revamp the dust suppression system in the open-air section of the bulk material storage facility used by the refractory shop to reduce limestone dust by 5% in the shop and 50% in the open-air section of the storage facility. (See also)
  • Revamp four dust collectors for refractory shop furnaces to triple the efficiency of dust collection during off-gas treatment. The project has been undertaken in stages during 2015 and 2016.

2016. Stoilensky

  • Reconstruct and upgrade dust collection systems.
  • Install a sprinkling and dust suppression system on the tailings pond beach.

2016. Altai-Koks

  • Revamp wagon tipplers’ dust collection system in coal blending units No. 1 and 2

2016. Lipetsk production site

  • Reconstruction of lime conveyor and wagon tipper aspiration units Nos. 1-2; with the construction of an aspiration system from lime receiving bunkers in sintering operations
  • Construction of a central off-gas cleaning system for shaft furnaces Nos.1-3 at the refractory shop
  • Reconstruction of aspiration unit No.20 at the refractory shop
  • Reconstruction of bulk material conveyor aspiration units (Nos. 1,2,3,7,8) of section No.3 with the replacement for sleeve filters at the refractory shop
  • Construction of a modular aspiration system for BF-4 at blast furnace shop No. 1
  • Reconstruction of the off-gas cleaning unit of rotary furnace No. 3 at the refractory shop; with electric filter replacement

2017. Altai-Koks

  • Build system for neutralising excessive cycled gases in the coke dry quenching plant of coke unit No. 2

2017. Lipetsk production site

  • Coke and chemical operations. Reconstruction of coke and chemical product recovery shop; unification of coke gas flows from coking plants Nos. 1,2,5,6. Reduction of specific air emissions

2018. NSMMZ

  • Revda: revamp the gas cleaning plant of EAF shops 1 and 2 (stage)

2019. Novolipetsk

  • Complete renovation of blast furnaces No. 4, 5 and 6. Expected impact: lower carbon oxide and dust emissions.
  • Revamp exhaust ducts of BOFs 2 and 3 in BOF shop No. 2. Expected impact: lower carbon oxide and dust emissions. (See also)

WATER PROTECTION

2016. NLMK La Louvière

  • Build an oily wastewater treatment system for rolling shops.

2016. NSMMZ (Nizhniye Sergi)

  • Build a water treatment facility for the surface water sewers.
  • Build new and renovate old water treatment facilities at the site.

WASTE MANAGEMENT

2014. Stoilensky

  • Use tailings in the construction of barriers between tailings pond sections.

2015. VIZ-Steel

  • Reclamation of the industrial waste landfill.

2018. Stoilensky

  • Upgrade the water reuse system: build a slurry dewatering unit and new water reuse and tailings transfer pipeline systems (in three phases) to adopt more efficient methods of processing, transporting and storing gangue for reduced environmental impact and energy consumption, and increased pipeline capacity.

2020. Novolipetsk

  • Reclamation of the slag heap.
  • Build a briquetting plant with an annual capacity of 700,000 tonnes; recycle 5.4 million tonnes of industrial waste; and recycle 395,000 tonnes of accumulated slag a year.

2024. NSMMZ (Revda)

  • Eradicate the plant’s tailings pond.


The second stage of the technical upgrade programme: impact

NLMK Group allocated more than 21 billion rubles for environmental projects during the second stage of the technical upgrade programme in 2007–2012, bringing total investment in upgrades and new construction to 258 billion rubles. This includes 7.5 billion rubles invested in environmental technology for NLMK Kaluga, a new generation mill opened in July 2013.

RUR - investment in upgrades and new construction from 2007 to 2012

The Group’s Russian operations boosted steel production by 52% over the period to reach 14.2 million tonnes, while air emissions decreased by 40% (from 37.5 to 22.6 kg per tonne of steel) and discharges into the water were reduced to one fifty-fourth of earlier levels (from 1.08 to 0.02 kg per tonne). The Lipetsk site, which accounts for 80% of the Group’s output, achieved zero waste water in mid-2009.

NLMK's environmental strategic objectives for 2013 – 2017

The 5-year strategic cycle ended in 2017 and all environmental goals were successfully achieved. An all-time low level of specific air emissions rate of 20.5 kg per tonne of steel was reached. At the same time, the Company managed to preserve a high level of waste disposal 86,9% (excluding mining waste) and recycled water turnover - 97,1%.

RUR - investment in upgrades and new construction from 2007 to 2017

Investment in environmental projects and initiatives over the period of Strategy 2017 totalled approximately RUB 29 billion. NLMK Group spent over RUB 5.7 billion on environmental projects and initiatives in 2017. The majority of investments in 2017 went towards projects and initiatives to improve air quality. For instance, NLMK Lipetsk upgraded gas-cleaning systems at six sections at the refractory, sintering and blast furnace shops. NLMK Group's other facilities executed projects aimed at reclamation of former landfill sites, construction of sewage treatment plants and noise pollution reduction initiatives, among others.
