1 PUBLISHABLE SUMMARY

CO2 generation is an inherent part of cement production due to the calcination of limestone CaCO3 converted to CaO and CO2 There are currently no feasible methods to produce clinker and thus cement without releasing CO2 from CaCO3 Furthermore cement plants typically have a lifetime as long as 30 50 years Altogether the most viable option to reduce significantly greenhouse gas
