Thetford Mines in Quebec is redeveloping its abandoned asbestos mining sites through the DuGrisAuVert Strategic Plan, which aims to utilize 450 million tons of mining tailings left from over a century of mining. The local government and businesses have identified economic opportunities in these tailings, which are rich in minerals like magnesium and iron.

Four priority projects have been outlined, including the establishment of the DuGrisAuVert cooperative to support reclamation efforts. Additionally, the American startup Vema Hydrogen plans to produce 'orange hydrogen' using the unique geological formations present in the area. This approach aims to turn the mining legacy into assets for future economic growth.
