Elements for the Design of Experimental Plant for LC3 ...

Abstract. Associated with cement manufacturing processes, large amounts of carbon dioxide (CO 2) are released into the atmosphere, and it is estimated that between 0.65 and 0.90 tons of CO 2 are emitted per ton of cement manufactured. By 2050, the demand for this binder is expected to exceed 5000 million tons, which would contribute to an increase of more than 3% of emissions.
