It’s difficult to imagine the Sudbury skyline without the iconic Superstack. A fixture of the city since the early 70s and the second tallest chimney in the world at 1,205 feet, the Superstack chimney has been a part of the Greater Sudbury skyline for almost 50 years.
However, due to the significant reduction of atmospheric emissions at Vale’s operations in Sudbury, Ontario, we will be taking the Superstack out of service in the first quarter of 2020. It will be replaced by two smaller, more efficient 450-foot stacks. Learn more [links to FAQs]
Construction of the new smaller stacks will begin early in 2017 and will take approximately two years to complete. We will continue to maintain the Superstack while we study how best to safely and carefully demolish its concrete shell. There is no immediate need for the shell to be demolished and it is expected to remain a part of the Sudbury skyline for several years to come.
