High sulphur dioxide emissions from the smelting of sulphide concentrate with high sulphur content are a key environmental issue for the Company. Nornickel’s strategic plan is to transform the Company into an environmentally clean and safe business by implementing the Sulphur Programme at the Polar Division and Kola MMC. In 2020, the Company plans to introduce light unmanned aircraft systems for monitoring environmental conditions on the Kola Peninsula and in the Norilsk Industrial District.
The Sulphur Programme is a major environmental project aimed at the gradual reduction of sulphur dioxide emissions in the Norilsk Industrial District and the Kola Peninsula.
The Sulphur Programme in the Polar Division is expected to reduce sulphur dioxide emissions in the Norilsk Industrial District by 45% in 2023 and by 90% in 2025.
As part of this program, Nadezhda Metallurgical Plant is implementing a project to capture the off-gases from flash smelting furnaces and neutralize the resulting sulphuric acid with limestone to produce gypsum. In 2019, the project documentation successfully passed a state environmental review; negotiations commenced for equipment supply contracts, and construction site preparations were completed.
At Copper Plant, a major production process upgrade is scheduled, including capturing sulphur dioxide from sulphur-rich off-gases and shutdown of low-grade gas converter operations, which have a significant effect on air quality in Norilsk during unfavorable weather conditions.
The Sulphur Programme at Kola MMC provides for the shutdown of obsolete production shops in Nickel near the Norwegian border and a modernization copper shop in Monchegorsk. These measures will completely eliminate sulphur dioxide emissions in the Russia-Norway border area and significantly reduce the adverse impact on the environment in Monchegorsk. The Programme is expected to reduce sulphur dioxide emissions from Kola MMC by 50% in 2020 and by 85% in 2021 (from a 2015 baseline).
