Options for cement production in Papua New Guinea: A study in choice of technology

This paper examines the technical options for local production of cement to satisfy Papua New Guinea’s needs. Both rotary and vertical kiln methods and different plant sizes are compared on economic grounds and also assessed against national objectives. Because of Papua New Guinea’s small and scattered demand for cement and high internal transport costs, the smaller vertical kiln units are more economic while small-scale manufacture is also more in line with national objectives.
