This JI project at YugCement plant in Ukraine aims to significantly decrease the CO₂ emissions from two sources: fossil fuel combustion and calcinations.  YugCement is the largest plant of the building materials industry in the south of Ukraine with design production capacity more than 1.25 million tonnes of cement per year.

Global Carbon is developing all documentation for this project including an approach to set the baseline and monitoring plan.

The project foresees the adoption of blast furnace slag (BFS) as decarbonised raw material in the raw meal fed to the kilns. The project target is to increase proportion of slag to some 15 per cent. Addition of slag reduces both, the emission due to the calcinations of raw materials in the kiln and fuel consumption.

Effect of slag addition occurs due to the following:

- less CO₂ is emitted during calcinations process in the kiln as slag contains significantly less CaCO₃ which decomposes to CaO and CO₂ at high temperature in the cement kiln;

- less heat and subsequently less kiln fuel is required for decomposition of limestone in the kiln. Therefore, less CO₂ emissions from fuel combustion occurs;

- slag reduces the overall moisture content of the slurry therefore less kiln fuel is consumed to evaporate moisture from it. Less CO₂ is emitted from fuel combustion.

Emission Reductions

The total expected emissions reductions are around 791,180 tonnes of CO₂e.
