Carbon Limit, developer of the CaptureCrete admixture proven to sequester carbon dioxide in finished slabs or structures, has announced CoolCrete, a concrete additive line infused with heat-reducing capabilities. To bring this first-of-its-kind product to commercial and residential projects worldwide, Carbon Limit has tapped two licensing partners, NCP Industries and Bison Innovative Products, that will soon launch a series of innovative products incorporating CoolCrete technology.

CoolCrete is a functional supplementary cementitious material that replaces up to 40 percent of conventional binder and reduces the carbon footprint of concrete production by a corresponding level. It achieves temperature reduction through improved solar reflectance and enhanced thermal emittance. By boosting concrete’s ability to reflect sunlight, CoolCrete helps reduce overall heat absorption in a concrete slab or structure, while simultaneously releasing the absorbed heat more efficiently. 

Incorporating CoolCrete into concrete projects offers an opportunity for user entities to generate high quality, validated and verified carbon credits, Carbon Limit notes. The agent is designed to directly combat the heat island effect frequently cited in urban areas and driving higher energy consumption due to increased air conditioning loads. Early data shows CoolCrete can reduce the temperature of concrete by up to 6°C.

“We’ve created an enhanced sustainable solution to directly address the heat crisis we’re experiencing across the globe, especially in highly populated urban areas,” says Carbon Limit Founder and CEO Tim Sperry. “Concrete is the second-most used material in the world after water, and global construction will only continue to expand. Through CoolCrete, we can put our homes, offices and even roads to work.”

NCP Industries and Bison Innovative Products currently offer a range of products that incorporate the licensed CaptureCrete formula. Both have begun work on new editions of premier products that incorporate CoolCrete technology. With products expected to come to market in late 2024, NCP Industries and Bison Innovative Products will play a key role in making CoolCrete-bearing products readily available to consumers and design professionals. 

“Combining Carbon Limit’s technology with our products has been a seamless effort. It doesn’t require new machinery, grants flexibility since we license the formula, is cost-efficient and helps the environment,” notes NCP Industries President Ryan Collison. “Carbon Limit allows us to expand our support of sustainable construction, and we couldn’t be more excited to continue this effort by getting CoolCrete-infused products on the shelves soon.”
