Canada's second-tallest freestanding structure is now being demolished, but how does one go about tearing down a monolithic chimney that rises as tall as New York City's Empire State Building? The Superstack — designed to better disperse smelting gas from Vale's Copper Cliff Complex — has stood as the tallest chimney in the Western Hemisphere throughout its existence. In its early years, the behemoth held the record for the world's tallest chimney until 1987, when it was overtaken by the Ekibastuz GRES-2 Power Station in Kazakhstan. Demolishing one of the tallest structures on the continent is a task you can't just attack head-on like your standard demolition project. There will be no wrecking balls or implosions here, but, instead, a meticulous disassembly of the enormous chimney.
