AI Cuts Factory Emissions by 30,000 Tonnes Per Plant

Heavy industry just got a powerful new tool in the fight against climate change, and it's saving companies millions while cleaning up the planet.

Gigaton, a company that builds AI software for factories, just raised $26 million to expand technology that's already cutting emissions at some of the world's largest cement and steel plants. The system doesn't just sit on top of existing controls. It replaces outdated technology that often dates back decades.

Here's how it works: The AI learns from each factory in real time, constantly adjusting things like fuel mix, kiln speed, and oxygen levels. Before making any change, it simulates what will happen, ensuring every decision improves both efficiency and emissions.

The results speak for themselves. Plants using Gigaton's technology are saving up to $3 million per year while cutting 30,000 tonnes of CO₂ annually. That's equivalent to taking 11,000 UK homes off the grid for an entire year.

Major companies including Adani Cement, Heidelberg Materials, and Holcim are already seeing the benefits. Kevin Lunney from Mannok Holdings explained that switching to alternative fuels is tricky because they're harder to control than traditional coal, but Gigaton's AI makes the transition smooth for operators in the control room.

The timing couldn't be better. Cement, glass, and steel production consumes about a quarter of the world's energy, and many factories still rely on manual controls that waste energy and pump out excess carbon. Meanwhile, facilities in China are already building fully autonomous plants that run without any on-site staff.

The Ripple Effect

Beyond individual plant savings, the potential for global impact is enormous. For large companies with multiple facilities, the cost savings could reach $100 million or more. More importantly, if this technology spreads across the entire sector, it could eliminate gigatons of carbon emissions.

The company plans to use its new funding to grow its team fivefold and expand into steel, glass, and chemicals manufacturing. They're already working with a small group of partners on the next generation of their control platform.

What makes this particularly hopeful is that factories don't have to choose between profits and the planet. The same technology that cuts emissions also reduces energy costs and creates more stable operations. Operators can even see why the AI makes each decision, building trust and understanding rather than replacing human oversight.

Heavy industry has long been one of the toughest sectors to decarbonize, but smart technology is proving that progress is possible right now.
