Use advice for data set The EPD covers the product stage („Cradle-to-Gate”). The selected system boundaries comprise the production of cement including raw materials’ extraction up to the finished product at the factory gate. The selected system boundaries are in accordance with the system boundaries given in EN 16908 (Figure 2).
Technical purpose of product or process Cement is a hydraulic binder, which means, a finelyground inorganic material which, when mixed with water,forms a mass, which sets and hardens as a resultof the reactions and hydration processes, maintainingstrength and durability even under water after hardening.The cement according to the EN 197-1 standard is calledCEM cement, properly measured and mixed with theaggregate and water, it should form concrete or mortarthat retains workability for a sufficiently long time,and after a specified time should obtain a certain levelof strength, and should maintain long-term stability ofthe volume.The CEM cements are made of different materials, butare statistically homogeneous in composition by qualityassurance in the production and material handlingprocesses.One of the main components of the cement is the Portlandclinker. For its production, calcareous materials(for example, limestone, chalk) and other natural orwaste materials are used, correcting the proportion ofthe silicates and aluminates, such as: clay, sand, fly ash,iron-bearing additives or slag from the steel industry.All of these materials are crushed, homogenised and introducedinto a rotary kiln where they are sintered at1450°C.In Cemex Poland the clinker is produced in two plants(Chelm, Rudniki). The main fuels used in the clinker firingprocess are alternative waste-derived fuels. Yearby year, the share of the alternative fuels is graduallyincreasing, while the use of fossil fuels is decreasing.Among alternative fuels, there is the biomass for whichthe carbon footprint is zero.The amount of the CO2 calculated in accordance withthe European regulations for monitoring the productionof the CO2 for the plant in Rudniki in connectionwith the production of the clinker is 722 kg of the CO2/Mg of clinker, and in Chelm 725 kg of the CO2/Mg ofclinker.Cement is produced by the joint grinding of the mainconstituents of the cement (for example, clinker, fly ash,blast furnace slag) with minor additional constituents,setting time adjuster and other additives.Cemex Poland produces cement in three plants (Chelm,Gdynia, Rudniki).The product phase (A1-A3, see Table 3) and the followingprocesses/modules were taken into account in theLCA analysis: A1 – the production of raw materials: fuel extraction,raw material extraction, electricity production, alternativefuel production, A2 – the transport: transport of raw materials, A3 – the production of a product: production of rawmeal, fuel consumption for firing, consumption of theelectricity for grinding.The figure below (Figure 1) shows the cement manufacturingprocess from the quarry to the shipment (productionphase) in a schematic way. -
General comment on data set The values determined to calculate A3 originate from verified Cemex Poland LCI inventory data. A1 values (raw materials) were prepared considering specific national EPDs, Ecoinvent data and economic allocation. The allocation rules used for this EPD are based on generalITB PCR A. Production of CEM II/B-V 42,5 R – HSR/NA is a line process in an manufacturing plant locatedat Chelm.CEM II/B-V 42,5 R – HSR/NA is not the only CEM productand the allocation in the manufacturing plant wasmade on the mass basis allocation. In the case of fly ash,a co-product from electricity production used as a cementconstituent, economic allocation was applied. Fora synthetic gypsum, allocated impacts are economicbased but plain gypsum wase (a value = 0) are neglectedin the cement LCA due to its very low impact.Minimum 99.5% of impacts from the production lineswere allocated to product covered by this declaration.Energy supply was inventoried and allocated to theproduct assessed on the mass basis. 99.5% of the consumed materials and 100% energy consumptionwas inventoried in factory and were includedin calculation. In the assessment, all significant parametersfrom gathered production data are considered,i.e. all raw material used per formulation, utilized energy,and electric power consumption, direct productionwaste, and available emission measurements. The followingprocesses were excluded from the LCA study: useof chromate reducing agents (total mass < 0.2% of cements),use of grinding balls. The total of neglected inputflows per module A1-A3 does not exceed the permittedmaximum of 1% of energy usage and mass.Tires consumption for transport was not taken intoaccount. Pre components, dyes, foils, papers, labels,tapes with a percentage share of less than 0.1%were not included in the calculations. It is assumedthat the total sum of omitted processes does not exceed1% of all impact categories. In accordance withEN 15804 machines and facilities (capital goods) requiredfor and during production are excluded, as istransportation of employees.

1This impact category deals mainly with the eventual impact of low dose ionizing radiation on human health of the nuclear fuel cycle. It does not consider effects due to possible nuclear accidents, occupational exposure nor due to radioactive waste disposal in underground facilities. Potential ionizing radiation from the soil, from radon and from some construction materials is also not measured by this indicator.
2The results of this environmental impact indicator shall be used with care as the uncertainties on these results are high or as there is limited experiences with the indicator.
