| Use advice for data set | Scope: This Environmental Product Declaration (EPD) covers the product life cycle stages A1-A3. It is valid for Portland Cement CEM II/A-M (T-L) 42,5 R, manufactured by Kunda Nordic Tsement AS in the plant Kunda, Estonia in 2021. This analysis relies on transparent, plausible and documented basis data. All the model assumptions, which influence the results, are declared. The life cycle assessment is representative for the products introduced in the declaration for the given system boundaries. System boundary: Type of EPD: cradle-to-gate (A1-A3) For the modelling of cement, both specific production data from HeidelbergCement and background data (especially for upstream processes) have been used. For life cycle modelling of the considered product, the verified Global Cement and Concrete Association GCCA Core model report and GCCA Project Database for EPDs of concrete and cement is used. The tool was developed by Quantis and is owned by the Global Cement and Concrete Association. The life cycle assessment in the tool has been implemented in compliance with EN 15804, the General Programme Instructions (GPI 3.01) for the International EPD® System, the product category rules c-PCR-003 Concrete and c-PCR-001 Cement. For the present study, version 3.1 of the GCCA Concrete EPD tool was used, largely being based on the database ecoinvent v3.5 A significant factor regarding primary data collection is the emission measurement directly at the plant. In line with the official regulations, regular data collections are established at HeidelbergCement group. The emission data of the clinker burning process are included in this LCA study. Preferably directly measured kiln emission values in the specific plant are considered. Noise, landscape impact, vibration etc. are not within the scope of this study. In case specific kiln emission data are not available, default values are automatically used by the GCCA tool. The selected system boundaries comprise the production of cement including raw material extraction up to the finished product at the factory gate. The product stage contains: Module A1: Extraction and processing of raw materials. Module A2: Transport of raw materials to the factory gate and internal transport. Module A3: Cement production. The construction stage, the use stage and the disposal stage are not included in the life cycle assessment of cement. | ||
| Technical purpose of product or process | The application of cement has a large variety. It is mainly used as a binder for concrete and mortar. The application in concrete is regulated in EN 206. According to this standard, general suitability is established for cement conforming to EN 197-1. | ||

| General comment on data set | Cement is a hydraulic binder. It consists of finelyground, non-metallic inorganic compounds. Cement is produced by grinding cement clinker and other main or minor constituents. When water is added to cement, a cement paste is formed, which sets and hardensthrough the hydration reactions. After hardening, it retains its strength and stability even under water. The declared product is a cement conforming with the composition of Portland Composite Cement CEM II/A-M (T-L) 42.5 R manufactured by Kunda Nordic Tsement AS in the plant Kunda in 2021. The calculation is based on plant-specific data. | ||

The calculation is based on plant-specific data. Technical data: The declared cement corresponds to the 42.5 standard compressive strength class with high early strength development (R) in accordance with EN 197-1. Declared unit: The declared unit is 1 t of CEM II/A-M (T-L) 42,5 R. | ||
