Thomas Concrete launches rapid rollout of CarbonCure technology

Solidifying its position as an industry leader in sustainability, Thomas Concrete of Atlanta, Georgia has announced the expansion of the CarbonCure technology across four additional concrete plants surrounding the Atlanta metropolitan region.

Thomas Concrete first installed CarbonCure’s carbon dioxide (CO2) recycling technology in its Doraville, Georgia plant in February 2016. Following the success at its pilot plant, the company decided to implement the technology across further locations. Plants based in Buckhead, Suwanee, Gainesville and Cumming will now be equipped with the CO2 recycling machinery, which will enable Thomas Concrete to supply greener concrete to construction projects throughout the greater Atlanta region by the fall.

The CarbonCure technology injects CO2 gas sourced from local industrial polluters into wet concrete, where the gas becomes chemically converted into a solid mineral. Not only is the greenhouse gas permanently captured, the process also enables concrete producers to reach strength requirements using less cement. As cement production accounts for 5% of the world’s greenhouse gas emissions, the reduction of cement prevents further CO2 from being emitted into the atmosphere.

By recycling CO2 in five of its Atlanta metropolitan plants, Thomas Concrete is expecting to reduce CO2 emissions by approximately 5 million pounds every year. This is equivalent to taking almost 500 passenger vehicles off the road each year. This is also equivalent to the amount of CO2 that 2150 acres of forestland would sequester annually. In other words, Thomas Concrete can now save almost as much CO2 as downtown Atlanta would save if it were entirely covered by trees, every year.
