| Use advice for data set | This environmental product declaration shows the life cycle assessment of the production of of Portland cement clinkers at the Oggaz plant of Lafarge Ciment Oggaz (LCO). Type of EPD: cradle-to-factory gate The system boundaries include the manufacture of LCO White Clinker including the extraction of raw materials through to the finished product at the factory gate. The product stage includes: Module A1: Extraction and processing of raw materials. Module A2: Transport of raw materials to the factory gate and internal transport. Module A3: Manufacture of cement or cementitious components. The construction stage, the usage stage and the disposal stage are not taken into account in the life cycle assessment for cement. |
| Technical purpose of product or process | LCO White Clinker is mainly used as a binder in the manufacture of cement. |

| General comment on data set | LCO White Clinker is a Portland cement clinker that is manufactured and monitored in accordance with EN 197-1. Portland cement clinker is a hydraulic material that is primarily used to make cement. It consists of non-metallic inorganic materials. Finely ground, it forms a suspension when water is added, which solidifies and hardens both in air and under water due to the onset of a hydration reaction and remains permanently solid. The composition of the product corresponds to the specifications of EN 197-1. |

| Technology description including background system | LCO White Clinker is manufactured at the Oggaz plant. Production of Portland cement clinker Limestone, marl, clay or their natural mixture, are required for the production of Portland cement clinker. These starting materials are mined in quarries, pre-crushed and transported to the nearby cement works. There they are homogenized into an intermediate product, with additional natural or secondary corrective substances being added to fine-tune the chemical composition. In the subsequent heating process, the Portland cement clinker is produced from the intermediate product. The firing process takes place in a rotary kiln, where the material is thermally converted at around 1450 °C and then rapidly cooled. The finished clinker is stored in silos. The Oggaz plant is ISO 9001 certified. |
