RUSAL has won the Vernadsky National Environmental Award for its dry gas cleaning system (DGCS) in the category "Innovative eco-efficient technologies in industry and energy". The new technology captures over 99.5 % of hydrogen fluoride and solid fluoride gases and provides savings in capital costs.

The scientific divisions which include the SibVAMI (Irkutsk), RUSAL ITC (Krasnoyarsk), Bratsk (BrAZ), Novokuznetsk (NkAZ) and Irkutsk (IrkAZ) aluminium smelters presented the DGCS.
"The overwhelming evidence of both DGCS’ energy efficiency and environmental friendliness along with its positive effect on CAPEX allowed RUSAL to switch swiftly to the use of its own technology and equipment, replacing foreign analogues. Support for and recognition from the expert community of corporate efforts to introduce new technological innovations is always important. It provides an additional incentive to continue long-term research aimed at improving environmental performance and encouraging the competitiveness of the Russian aluminum industry, and consequently, the entire national industry as a whole," said Viktor Mann, RUSAL’s Technical director.
RUSAL said eight DGCS’ are already in operation at the Bratsk (BrAZ), Novokuznetsk (NkAZ) and Irkutsk (IrkAZ) aluminium smelters. The company will install over 20 modern gas cleaning systems by 2025.
The capital expenditure, allocated to the environmental retrofitting programme at the BrAZ, NkAZ and IrkAZ, including DGCS’ installation and the transition to Eco-Soderberg technology, totals more than 18 billion rubles from 2017 to 2024.
