Environmental Aspects of UC RUSAL’s Aluminum Smelters Sustainable Development
2019
RUSAL is currently implementing an environmental strategy that includes increasing the number of pre-baked (PB) pot lines and implementing global environmental standards at the existing smelters. The following has been achieved:
implementation of new Eco-Soderberg cells with environmental indicators that are comparable to PB cells;
Construction of a testing area for inert anode cells that are intended to replace Vertical Stud Soderberg (VSS) cells;
Implementation of cutting-edge online and video systems for both emissions control and cell condition monitoring;
Testing of new types of binder with either a reduced or a close-to-zero content of benzo(a)pyrene;
Construction of high-performance GTCs;
Development and implementation of technologies for sulfur recovery;
SPL recycling, solid waste treatment and recycling.
This paper provides an overview of the results of more than 10 years of efforts to reduce the environmental footprint of RUSAL’s smelters.
