ImpactAlpha, July 12 – The race is on to decarbonize heavy industrial materials like concrete, cement and steel. CarbonCure injects CO2 into concrete, sequestering carbon and strengthening the final product. The process also reduces concrete’s overall carbon footprint by using less cement in the manufacturing process.
The Canada-based green concrete maker says its method of reducing concrete’s carbon footprint has curbed about 320,000 tons of CO2 and cuts lifecycle carbon emissions from concrete by about 5%.
The company has customers in more than 30 countries.
Blue Earth Capital led CarbonCure’s $80 million equity round. The company is also backed by Breakthrough Energy Ventures, Amazon, Microsoft and others.
Green cement
Cement, the key ingredient in concrete, is responsible for more than 7% of global emissions. Material Evolution raised $19 million for its low-temperature cement production. Sublime Systems snagged $40 million for “electrified” cement, which it claims is a zero-carbon product. Last year, Brimstone Energy took in $55 million for “carbon negative” cement that uses calcium silicate as an alternative to limestone.
