Our New EAF Facility Will Meet the Most Stringent Air Quality Standards

Our Commitment to Reducing Air Emissions

As part of our transition to EAF steelmaking, we are constructing two new state-of-the-art fume treatment plants that will effectively control air emissions and meet the newest, most stringent air quality standards.

This effort builds upon our previous campaigns that reduced airborne particulates from roadways. Additionally, we are planting trees, grass, and flower gardens around the site to reduce the amount of airborne dust stirred up by prevailing winds and material movement.

Algoma’s Transition to EAF Steelmaking

A Transformational Investment in Green Steel—and a Greener Future

Our multi-year, multi-million-dollar investment in Electric Arc Furnace (EAF) steelmaking is the largest decarbonization project in Canada. It is expected to reduce our carbon emissions by up to 70%, significantly shrinking our environmental footprint.

Environmental
Policy

We are committed to building a greener future by reducing our environmental impacts, including air emissions, in alignment with our Health, Safety & Environment Policy. We routinely review and audit operating practices to ensure compliance with environmental policies and legal requirements.

Transition to EAF Steelmaking

The new EAF facility will operate with state-of-the-art fume treatment plants, designed to meet stringent air quality standards. It is expected to significantly reduce carbon emissions by up to 3 million tonnes annually, which is roughly equivalent to taking nearly 1 million cars off the road.

Current Emission Control Measures

We reduce particulate emissions through road dust control programs, paving schedules, dust suppressants, investments in baghouse technology, and emission control systems. We also implement targeted initiatives, including coal dust management and enhanced particulate capture systems.

Performance & Compliance

Regulatory Framework

Algoma operates in compliance with Ontario’s Environmental Protection Act, including the applicable regulations it falls under. The transition to EAF steelmaking will allow us to meet general Ontario air quality standards and eventually eliminate the need for site-specific standards.

Continuous Improvement

In addition to our aggressive campaigns and targeted initiatives to curb particulate emissions and improve overall air quality performance, we will continue to conduct ongoing maintenance and improvements to meet regulatory requirements and further reduce air emissions.

Projected Carbon Emissions Reductions considerations

The projected carbon emissions reductions presented on this website are based on calculations derived from legacy data. These projections utilize international standards and benchmarks for electric arc steelmaking (EAF) and related processes. While every effort has been made to ensure accuracy, these calculations may not fully reflect the latest technological advancements, operational changes, or real-time emissions data. Actual reductions in carbon emissions may vary based on site-specific factors, new innovations, and evolving industry practices. This information should not be interpreted as a definitive guarantee of future environmental performance or sustainability outcomes.
