Could a humble, charcoal-like substance hold the key to Algoma Steel's sustainable future? It might sound too good to be true, but biochar—a form of charcoal made from plant matter—is being touted as a game-changer for the steel industry. And this is the part most people miss: it’s not just about reducing emissions; it’s about transforming waste into opportunity.
Sault Ste. Marie is exploring a partnership with local forestry companies to produce biochar, which could play a pivotal role in Algoma Steel's transition to electric arc furnaces. But here's where it gets controversial: while biochar promises to decarbonize steel production, its large-scale implementation raises questions about resource allocation and economic feasibility. Is this the green solution we’ve been waiting for, or just another experimental detour?
Biochar is created by heating plant material in a low-oxygen environment, a process known as pyrolysis. This isn’t your average charcoal—it’s a high-tech solution with multiple benefits. In electric arc steelmaking, biochar can act as a foaming agent to protect the arc, replace traditional carbon sources like coke or anthracite, improve slag dynamics, increase steel yield, and—most crucially—reduce CO₂ emissions. It’s like killing multiple birds with one stone, but with a greener twist.
At a recent city council meeting, Ward 5 Coun. Corey Gardi emphasized the potential of biochar, stating, 'The math is pretty much already done.' He highlighted Ontario's 2025 Interim Report on the Forest Biomass Action Plan, which identifies biochar as a primary strategy for carbon reduction in steel production. Gardi also noted that the province is eager to fund large-scale biochar projects in cities with both steel mills and forestry residue—a perfect fit for Sault Ste. Marie.
But here’s the catch: While Algoma Steel hasn’t built its own biochar plants, it’s positioned as a key customer for regional producers like CHAR Technologies, which has expanded its facilities in Ontario. This raises a thought-provoking question: Can a city still reeling from the early closure of blast furnaces and layoffs of 1,000 workers truly lead the charge in green innovation? Or is this just wishful thinking?
Gardi pointed out that 'tens of millions of dollars' are available for such projects, including funding from the federal Indigenous Forestry Initiative. 'The more we can do to get the economy going, the better,' he said. As Sault Ste. Marie enters 2026, the city is at a crossroads. The closure of blast furnaces and subsequent layoffs have left a mark, but Gardi believes this could be the beginning of a new chapter for a city with a rich industrial heritage.
City council voted in favor of a resolution to explore biochar as part of a broader 'green economy' initiative, which includes a district energy network to capture industrial waste heat and prioritizing 'green logistics' at the proposed port expansion. These initiatives aim to facilitate the movement of bio-products and critical minerals essential for the electric vehicle (EV) supply chain.
So, what do you think? Is biochar the sustainable solution Algoma Steel needs, or is it too early to tell? Could this be the spark that reignites Sault Ste. Marie's economy, or are we placing too much hope in unproven technology? Let’s keep the conversation going—share your thoughts in the comments below!
