    Per tonne of cement produced, 60-130kg of fuel and 110KWh are required (unep, 2013). This whole process will emit approximately one tonne of CO_2 into the atmosphere, per tonne of cement produced. It is fairly obvious that the current production process is careless in terms of the amount of CO_2 produced, the amount of electricity it requires and the exuberant level of resource consumption needed.
