Cambridge claims that using recycled cement as flux in steel furnaces (which can use recycled steel and renewable electricity), the resulting slag becomes Portland cement again, usable in concrete. This can reduce global co2 emissions by 7.5%. #climatechange #recycling https://www.cam.ac.uk/stories/cement-recycling
Cement recycling method could help solve one of the world’s biggest climate challenges

Researchers from the University of Cambridge have developed a method to produce very low emission concrete at scale – an innovation that could be transformative in the transition to net zero.

@obviousdwest it doesn’t say that it can reduce CO2 emissions by 7.5%. Cement production makes up 7.5% of global CO2 emissions, and concrete it one component of cement. What it does is that it can reduce CO2 emissions of concrete. The article doesn’t specify by how much though. But for sure << 7.5%.
