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 16908:2017.
Technical purpose of product or process GÓRAZDZE CEMENT S.A. offers Portland lime cement of strength class 52.5 with high early strength (R) is produced in the Górazdze Cement Plant and in the Ekocem Plant. The main component of CEM II/A-LL 52.5R cement is Portland clinker (80÷94%), ground limestone (6÷20%) and setting time regulator (calcium sulphate). Portland lime cement PN-EN 197-1 - CEM II/A-LL 52.5R meets the requirements of the PN-EN 197-1 standard "Cement - Part 1: Composition, requirements and conformity criteria for common cements". Portland cement CEM II/A-LL 52,5R is offered by GÓRAZDZE CEMENT S.A. in bulk. The following figure 1 is a schematic representation of the cement manufacturing process stages from quarry to cement mill (production stage). The natural raw materials for cement production are mainly calcareous materials such as limestone, sand and alumina-containing materials such as clay or shale, which are widespread. Alternative raw materials, such as different type of ash, slag or other waste materials are used in the process as substitutes for natural ones. Raw resource is preheated using input gases and then fired in a rotary kiln at a temperature of approximately 1450ºC. Currently one of the main fuels used in the process is alternative fuel that is derived from waste and its share is growing. Górazdze, through the use of alternative fuels, tries to reduce environmental damage, which is one of the basic strategic assumptions of the company. The LCA assessment encompassed the production phase and the following processes/modules: A1 – raw material production: fuel mining, raw material mining, electricity generation, alternative fuel production; A2 – transport: raw material transport; A3 – production of the product: raw meal production, consumption of fuel for firing, electricity consumption for grinding. -
General comment on data set The values determined to calculate A3 originate from verified manufacturer inventory data. A1 values (raw materials) were prepared considering national specific data, Ecoinvent data and economic allocation (for a steel and energy coproducts - gypsum, slag and ash). The allocation rules used for this EPD are based on general ITB PCR A. Production of cement is a line process (see figure 1). CEM II/A-LL 52,5R is not the only CEM product and the allocation in the manufacturing plant (CEM I, CEM II, CEM III) was made on the mass basis allocation for mixing impacts and clinker mass allocation in the CEM product. In the case of blast furnace slag use in cement production (other then CEM I), a co-product from steel production used as a cement constituent, economic allocation was applied. In the case of fly ash, eco-product from electricity production used as a cement constituent, economic allocation was applied. For a synthetic gypsum, allocated impacts are also economic based. Subsequent processes (e.g. granulation and grinding of blast furnace slag) were entirely allocated to the co-products. Minimum 99.5% of impacts from the production lines were allocated to product covered by this declaration. Energy supply was inventoried and allocated to the product assessed on the mass basis. Emissions allocated in clinker production are assessed using international methods for emission system declaration. 99.0% materials and 100% energy consumption were inventoried in a factory and were included in calculation. In the assessment, all significant parameters from gathered production data are considered, i.e. all raw material used per formulation, utilized energy, and electric power consumption, direct production waste, and available emission measurements. The following processes were excluded from the LCA study: use of chromate reducing agents and use of grinding balls. The total of neglected input flows per module A1-A3 does not exceed the permitted maximum of 1 % of energy usage and product mass. Tires consumption for transport was not taken into account. The components like: dyes, foils, papers, labels, tapes with a percentage share of less than 0.1% were not included in the calculations. It is assumed that the total sum of omitted processes does not exceed 1% of all impact categories. In accordance with EN 15804 machines and facilities (capital goods) required for and during production are excluded, as is transportation 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.
