Carbon-Capturing Concrete CarbonCrete Used in First Commercial Building: Each Structure Permanently Sequesters 200 Tons of CO2

Construction is a major source of global carbon emissions, accounting for approximately 8% of worldwide CO2 output. Traditional cement production emits about 0.6 tons of CO2 per ton of clinker, with global cement consumption reaching approximately 4 billion tons annually. If concrete could absorb rather than emit carbon, the construction industry's carbon footprint would be fundamentally rewritten.

On July 1, 2028, Singapore building materials company CarbonCraft announced that its carbon-capturing concrete CarbonCrete was deployed in its first commercial building project—a 12-story office building in Jurong, Singapore. During production, CarbonCrete uses a special mineralization process to inject industrially captured CO2 into the concrete matrix, where it reacts with calcium ions to form stable carbonate minerals permanently fixed within the concrete.

CarbonCraft co-founder Dr. Tan Wei Lin explained: "Each cubic meter of CarbonCrete can sequester approximately 50 kg of CO2. A 12-story office building uses about 4,000 cubic meters of concrete, meaning this building permanently sequestered roughly 200 tons of carbon dioxide during construction—equivalent to the annual emissions of about 40 cars."

CarbonCrete's mechanical properties match traditional concrete, with compressive strength reaching 40 megapascals, meeting most structural requirements. Cost-wise, CarbonCrete is about 15% more expensive than traditional concrete, but when carbon credit values are factored in, the actual cost difference can be offset or even reversed.

Singapore's Building and Construction Authority has listed CarbonCrete as a bonus item for green building certification. China State Construction Engineering Corporation announced it is evaluating CarbonCrete technology and plans pilot applications in the Chinese market.

CarbonCraft has completed a $120 million Series B round and plans to build three CarbonCrete production facilities in Southeast Asia and China by 2029.
