Cement kiln dust is a by-product of cement clinker production, and has about 35 wt% of CaO and 2 wt% of MgO. Therefore, cement kiln dust has a high CO 2 storage capacity between 191 and 256 kg CO 2 /tonne of cement kiln dust. 11 Another source of Ca-based industrial waste is the paper industry.

In OPC, clinker factor is ~90 per cent thus, it has a carbon footprint of around 800 – 850 kg/MT of cement. When clinker is replaced with SCMs, the CO2 emissions are reduced as SCMs don't have embodied carbon emissions. That is why blended cement have much lower carbon footprint than OPC.

Clinker is produced by heating crushed limestone and a mix of other materials (clay and sand) to 1450 °C in a rotary kiln. Clinker is later ground down to a fine powder and mixed with gypsum and other ingredients to make cement. The rotary kiln is the heart of the manufacturing process where raw materials are heated up and decarbonisation of ...

Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.
