METHOD AND PLANT FOR MANUFACTURING A CEMENTITOUS MATERIAL

A process and a plant for manufacturing a cementitious material and a CO2 rich exhaust gas stream. The plant comprising a carbonizing device, a calcining device, a furnace device, and a cooling device. The carbonizing device, furnace device, and cooling device are fluidly connected. The calcining device is substantially fluidly isolated from the carbonizing device and furnace device. The process comprising the steps of contacting a cementitious raw material suitable for binding carbon with a CO₂-containing gas in a carbonizing device to provide a carbonized material. The carbonized material is calcined in the calcining device to provide a CO₂ gas and a decarbonized material. A portion of the decarbonized material is provided to the carbonizing device and another portion is provided to the further device. The material is further sintered and cooled to provide a cementitious material.
