The cement industry emits significant amount of CO2 during the production of cement (clinker). The two sources are fuel combustion and the decarbonisation of limestone. The potential to reduce the specific emissions of CO2 in
-
Switching from a dry production process at a (semi-)dry process;
-
Utilization of slag or fly ash as alternative raw material;
-
Utilization of biomass as fuel;
-
Reducing the clinker content of the cement.
Our flag ship JI project in the cement sector decreases the emissions of fossil fuel combustion by changing the technology of cement production from a wet production process to a dry production process will be implemented at Podilsky Cement in
Global Carbon B.V. developed all documentation for this project including an approach to set the baseline and estimate the emissions reductions. The expected energy consumption of the dry cement production system at Podilsky Cement will be approximately 3,180 MJ per tonne of clinker produced (760 kcal/kg). This constitutes a reduction of 53% in energy consumption!
A total of 3,023,403 tonnes CO2 will be reduced until the year 2012. Click here for detailed information on this project.
Global Carbon is developing several other JI projects in the cement industry, for example at Volyn-Cement and Yug Cement factories, which are both owned by Dyckerhoff. Also at Kryvyi Rih Cement and DonCement owned by Heidelbergcement. The main goal of these projects is to reduce the CO2 emissions from two sources: fossil fuel combustion and calcinations.
