The development of construction industry has certainly increased the demand of cement production and usage. On the other hand, cement manufacturing is considered as an energy intensive process in which the fuel demand is very high. Furthermore, the fuel crisis and fuel prices hike at national and international level is an alarming situation for the sustainable future of these industries. Therefore, researchers and industrialists are trying to find alternative fuel for cement industry which should be economically viable and cleaner solution. The main objective of this research work is to utilize Pet Coke and Carbon Black as an alternate fuel in kiln of a cement industry and determine their effects on the product cost. In this study, up to 20% Pet coke and carbon powder are burnt in the cement kiln along with the imported coal. The results showed that both alternative fuels increased carbon monoxide (CO) formation due to low volatile matters. Moreover, the particulate matters (PM) increased while using pet coke in comparison to the imported coal. It was found that the fuel cost reduced by using pet coke and carbon powder, however, the environmental pollution was increased
