380-meter chimney has loomed over city since 1970
Mining giant Vale says that the Superstack will be standing on Sudbury’s skyline until 2020, at which point the iconic structure will be slowly taken apart.
Angie Robson, Vale’s manager of corporate affairs, told CBC News that with recent pushes by the company to reduce emissions, the stack has simply outlived its usefulness. “It’s simply too big for our needs, given the reduction in emission we’ve been able to achieve,” Robson said. “So it’s going to stay in service until 2020.”
The 380-metre high stack was built in 1970 to disperse sulphur gases and other byproducts of the smelting process away from the city. “It’s simply too big for our needs, given the reduction in emission we’ve been able to achieve,” Robson said. “So it’s going to stay in service until 2020.”
The 380-metre high stack was built in 1970 to disperse sulphur gases and other byproducts of the smelting process away from the city. With the project’s completion, the company said it can now turn its attention to the last days of the Superstack.
“There’s a huge steel liner inside the stack that needs to come out right away because of corrosion issues,” Robson said. “In 2020 that will come out. In the years after that the concrete shell will slowly come down.”
