Clinker is the intermediate product used in the manufacturing of cement. There are two primary processes used to manufacture clinker: the dry process and the wet process. Our plants use the dry process, which is more energy efficient. In the wet process, the raw materials are mixed with water to form slurry, which is fed into a kiln.

Here's how the grinding process fits into the cement production cycle and its implications: • Raw Material Preparation: The grinding process occurs after the raw materials, such as limestone, clay, iron ore, and others, are extracted and prepared. These raw materials are crushed, dried, and ground to a fine powder in the grinding mills.

CDIAC's method for estimating process emissions from cement production by country is taken from a report by Griffin (1987) and requires that cement production data in tonnes are multiplied by a fixed factor 0.136 to obtain tonnes of carbon emitted as CO 2, i.e. 1 t of cement produced results in 0.136 × 3.667 = 0.50 t CO 2 (Boden et al., 1995).
