Energy cost contributes to about 40-50% of cement production cost in Nigeria depending on the production process and type of cement with 1 tonne of cement requiring 60-130 kg of fuel or its equivalent and about 105 kWh of electricity [ 3 ]. Fossil fuels like coal, pet coke, fuel oil, and gas are the primary fuels used in the cement kilns.

Brussels 15 May 2017 - Increasing the rate of co-processing waste in the EU28 cement industry to 60% will avoid 26 million tonnes of CO 2 - emissions and can reduce the costs for about €12 billion of investments in dedicated waste-to-energy incineration plants. The implementation should be supported at national level mostly, as the barriers to realize this potential differ per member state.
