Germany: 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.”

Germany: Spenner has ordered a grinding plant from Christian Pfeiffer to be built at its main site in Erwitte. The unit will include a Ø 4.4 m x 14.0 m ball mill and a QDK 187-Z cross-flow rotating cage separator. In addition to the grinding plant, the engineering, procurement and construction (EPC) project also includes the planning of steel and concrete constructions as well as electrical switchgears.

Christian Pfeiffer is also responsible for the manufacture, delivery and optimum coordination of all associated components such as filter systems, bucket elevator, fans, chutes, samplers, reject transport and additional silos for additives. Staff training and performance test procedures carried out by the Christian Pfeiffer employees on site are also part of the commissioning of the plant.
