The Rise of Carbon Neutral Concrete

Climate change is impacting millions of people around the world. And with gas prices getting higher in the US everyday, there is a lot of concern about the state of our environment. Here in the US, cement manufacturers have committed to reach carbon neutrality by 2050. One of the ways to achieve that goal is with carbon neutral concrete. Let’s jump in and find out more about this exciting development!

Concrete Background Information

Did you know that 8% of global emissions come from making concrete? Heating up the limestone to almost 2,500 degrees Fahrenheit releases large amounts of carbon into the air. However, the limestone is then mixed with other ingredients to create cement. This mixture keeps the concrete together. For that reason, companies have created concrete this way for years and years.

How Can Concrete Become Carbon Neutral?

Currently, there are a few companies creating carbon neutral concrete, including Cemex and CarbonCure. There are a few different ways to achieve this. For example, Cemex uses an engineered compound to bind the concrete instead of the heated up limestone. CarbonCure actually injects recycled carbon dioxide into the mix and creates a stronger product. Both of these are reducing carbon impact by 70% by keeping production waste out of the air, but this technology is still early in its launch. Therefore, 100% carbon neutrality is reached by purchasing carbon offsets. But as an added benefit, there is no carbon released when destroying a building.  Low carbon concrete is growing in production and relevance. In addition, Amazon even invested in this process back in 2020.

Ready to go Green with Your Construction?

Since we are waiting for carbon neutral concrete to hit our shelves, we are already devoted to reducing our carbon footprint. For instance, we only use LEED certified blocks. These LEED blocks are made out of 43% recycled content and is just one of the ways Elston Materials is going green.
