Berlin-based AI startup Alcemy, in partnership with German cement producer Spenner, has produced a commercially viable low-carbon cement alternative named ‘CEM X’. This product reportedly reduces carbon emissions by 65% and has less than 30% clinker content, according to the company. The composition incorporates a blend of 33% granulated blast furnace slag and 37% limestone.
Alcemy CEO Leopold Spenner said “With ‘CEM X,’ we have reached a significant milestone on our journey to decarbonising the cement industry.”
