Vale celebrates completion of $1B Clean AER project
SUDBURY, Ont. – On Sept. 14 Vale held a special celebration in this mining town to mark the end of its Clean AER (atmospheric emission reduction) project. The $1-billion undertaking was the largest single environmental investment in the town’s history.
Vale’s base metals division is headquartered in Sudbury, Ont.
Clean AER achieved an 85% reduction in previous sulphur dioxide emissions and a 40% reduction in metal particulate emissions.
Work began in 2012 and proceeded safely without the need to shut down the Copper Cliff smelter. Two new converters, a wet gas cleaning plant, a new secondary baghouse-fan building were constructed. The smelter converter flues were also rebuilt.
Part of the work involved removing the steel liner of the iconic, energy-gobbling Superstack and taking it out of service. The concrete shell will be removed over the next several years. Two new 137-metre stacks are being built at the smelter. The new stacks will cut greenhouse gas emissions and be less energy intensive as well.
Not only has Clean AER have a positive environmental impact, it has also generated welcome economic impact with local suppliers and the community. Approximately 550 construction jobs were generated while the project was underway.
