CarbonBuilt To Make Commercial Concrete With No Embodied Carbon

CarbonBuilt To Make Commercial Concrete With No Embodied Carbon - Carbon Herald

US-based company CarbonBuilt announced a new critical milestone – the production of 100% Ordinary Portland cement (OPC)-free binder that will enable the manufacturing of concrete with close to no embodied carbon. 

As one of the most emissions-intensive sectors, decarbonizing the cement and concrete industry is vital to achieving meaningful emissions reductions in time to mitigate the devastating consequences of global warming. 

CarbonBuilt offers a viable solution for the decarbonization of concrete production through its core technology, which traps captured CO2 emissions in cement blocks. 

The new product that CarbonBuilt has developed is essentially a low-carbon alternative to cement, which reacts chemically with the captured carbon dioxide and results in the creation of concrete blocks. 

The blocks are no different than their traditional counterparts in both price and quality, but do contain close to zero embodied carbon, making them a much more sustainable and environmentally friendly alternative. 

CarbonBuilt’s cement-free binder will be used to produce blocks in Childersburg, Alabama, where the company’s first commercial partner Blair Block is located.

Both companies plan to have the first batch of blocks produced as commercial scale early next year. 

Rahul Shendure, CEO of CarbonBuilt commented on the occasion by saying: “Our technology enables the concrete industry to decarbonize profitably. While carbon-negative concrete is not a prerequisite for this to happen, it has been our goal to demonstrate no-compromise carbon-negative concrete, and eliminating OPC from the mix demonstrates that it is possible.”

Shendure also noted that the combination of cement-free mix design with the inexpensive utilization of carbon dioxide emissions paves the way for scaling carbon-negative concrete production.
