Brimstone Co-Founder and CEO Cody Finke

If cement were a country, it would be the third-largest emitter of carbon dioxide in the world, behind only China and the United States. That’s because cement production alone accounts for about five and a half percent of total global greenhouse gas emissions. And while that might seem really high, it actually makes sense. Just look around you: from roads to bridges, sidewalks to buildings, cement is everywhere. It’s a critical building block of modern infrastructure.What’s striking about cement production is that most of the emissions actually come from the chemical reaction itself—not just from burning fuel to heat the kiln. Cement producers use limestone, a well-known carbon-storing rock we’ve highlighted in other episodes for its direct air capture potential. But when limestone is heated to make cement, the opposite happens: it releases carbon dioxide, accounting for about 60% of the sector’s total emissions. So even if you used 100% clean electricity to power the kilns, most of the emissions would still result from this chemical process.Limestone was originally selected as a main ingredient for cement largely because it was the cheapest option. But what if it wasn’t? What if there were other rocks we could use that didn’t emit greenhouse gases at all? Better yet, what if they could produce the ingredients for cement cleanly—and generate other products critical to industry?That’s exactly what Cody Finke, CEO and Co-Founder of Brimstone, is aiming to deliver: a way to make cement without the emissions—and create other essential industrial materials along the way.SponsorsWatt It Takes is brought to you by HSBC Innovation Banking who is proud to bank some of the most exciting companies pioneering the technologies of tomorrow.With specialist financing support, deep understanding of the challenges, and a global network across more than 50 markets, they help clients scale breakthrough innovations and take them to the world.
