modern day cement production. This involves the heating of mineral carbonates to high temperature in kilns. If this heat is generated by burning fossil fuels, CCS equipment must be installed to ensure the overall process has the maximum neg- ative emission impact. Work input is also required for rock crushing and post kiln.
