Lowering carbon emissions from cement and concrete ...

Feb 22, 2021  By offsetting the carbon footprint of the cement in concrete, Blue Planet says its aggregate compensates for the cement component’s carbon footprint, making the concrete a net-carbon storage sink. The process also creates upcycled concrete aggregate as a by-product, reducing the need for further extraction processes.
