#1 - How we can lower the carbon footprint of concrete today
December 2022 - by Johannes Tiefenthaler
With over 1 billion tons per year, concrete from construction and demolition is the world's single largest waste stream. ETH spin-off Neustark developed a method to help turn this waste stream into a carbon sink, thus permanently removing CO2 from the atmosphere and generating negative emissions. To achieve that, a solution was conceived that mineralizes CO2 and stores it in recycled concrete aggregate. In 2017, the company started developing this process, and in 2022, they were able to deploy it at industrial scale within the framework of DemoUpCARMA.
