It is time to bid farewell to the iconic Sudbury superstack. Vale Base Metals is ready to complete the final phase of the $1 billion atmospheric emissions reduction (AER) project by dismantling the copperstack and superstack.
The Clean AER project has enabled Vale’s Sudbury Operations to eliminate 100,000 metric tonnes of sulfur dioxide emissions each year (equivalent to 1,000 railway tanker cars of sulphuric acid), bringing emissions down to 30% below the provincial standard. The superstack has been inactive since 2020, symbolizing significant progress toward cleaner air and a healthier environment.
Both chimneys will be carefully deconstructed over several years and will be done according to strict safety protocols. The copperstack will come down first and it is expected that this work will be completed by 2025. Planning and preparation are already underway to get the superstack ready for dismantling. This project is estimated to begin in late spring 2025 and last until 2028-29.
