Ethiopia’s cement industry has enjoyed substantial growth in the past decade. However, challenges linked to the government’s investment policy could erode these gains, as Shem Oirere reports With nearly 16.5 million tonnes of cement capacity and 10% average growth in annual consumption, Ethiopia is among the top cement producers in sub-Saharan Africa.

clinker production demands major energy input and raw materials which is the major source of gas emission and toxic pollutants due to their physical and chemical reactions in the cement kiln system (EEA, 2009). In line with this, cement production contributes about 10% to the total global mercury emissions (Marquita, 2010).

There are more than twenty types of cement used to make various specialty concrete, however the most common is Portland cement. Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln.
