French oil major Total has invested in a US process to make sustainable cement and concrete, Reuters reports.
Total Energy Ventures has invested in Solidia Technologies, which has developed a process that uses carbon dioxide to cure concrete.
It said this allows for a 70 percent reduction in the carbon footprint of the cement and concrete manufacturing process and allows 60 to 100 percent of the water used to be recycled.
Total said the process, developed at New Jersey’s Rutgers University in the United States, has been tested with customers in recent months. It gave no financial details of the deal.
