1. Cement plant distance from sewage plant [km]
2. Price of CO2 emission permit [EUR]
3. PLN/EUR exchange course
4 .Portland clinker kiln efficiency [%]
5. Cost of obtaining energy [PLN/1GJ]
6. Cost of extraction of 1 tonne of limestone [PLN/1 tonne]
7. Price of 1 tonne of carbide lime at the sewage works [PLN/1 tonne]
8. Transportation costs [PLN/1 tonne/km]

The above presented figure shows an empirical estimation of profits after an introduction of carbide lime as a raw meal component for Portland clinker production/sinterisation. Using the sliders below the figure allows to predict the profitability of CARLIMENT implementation within a specific distance from the waste deposit by giving the specific market conditions predictions. The formula behind the graph takes into account savings from substituting calcium carbonate with calcium hydroxide, savings from limiting CO2 emissions and savings from energy efficiency improvement of the process. CaCO3 and Ca(OH)2 stechiometry and thermodynamical calculations are taken into account as well. The equation includes extraction and logistics cost. The balance is given for 1 tonne of dry carbide lime utilized as a Portland clinker raw meal component.
