| Use advice for data set | All processes from raw material extraction to product transport to the construction site and assembly are included in the analysis as well as end of life stage and phases beyond the system boundary (A1 - A5, C1-C4, D). The basic production process comprises mixing of raw materials together. Raw materials are cement, aggregate, filler and additives delivered as bulk, big bags or smaller bags from EU. Ready mixed product then packed to small bags, big bags or in silos for bulk deliveries. Majority of floor screed is delivered as bulk, where only water is added to pump truck silo being ready for the installation. Floor screed doesn't require any maintenance during the use stage, so stage B is not considered. When building is demolished at the end-of-life floor structure with floor screed integrated into concrete slab are crushed. 90 % of crushed concrete is recycled and used to replace natural gravel in soil construction, remaining 10% being disposed into landfill. System boundaries (cradle-to-gate with options) are illustrated in the picture below. |
| Technical purpose of product or process | webervetonit 130 core Self Level Comfort is pumpable, low-alkaline, casein-free, cementitious floor screed for new construction and renovation. The product is suitable for special floor structures in homes, for example in Comfort heated floor solution or impact sound insulation solutions. An excellent substrate for e.g. PVC, linoleum and resin floors. The surface of the screed must be smoothed before gluing the floor covering. It is also suitable as a conventional levelling screed for concrete floors. Beyond bulk delivery available also in 20 kg bags and 1000 kg big bags.

| General comment on data set | Data quality: Specific data for the product composition are provided by the manufacturer. They represent the production of the declared product and were collected for EPD development in the year of study. Background data is based on registered EPDs according to EN 15804, Ostfold Research databases, ecoinvent and other LCA databases. The data quality of the raw materials in A1 is presented in the table below. Plant manufacturing data is collected for 2019. Raw materials, transport and production volumes are also for 2019. Allocation: The allocation is made in accordance with the provisions of EN 15804. Incoming energy and water and waste production in-house is allocated equally among all products through mass allocation. Effects of primary production of recycled materials is allocated to the main product in which the material was used. The recycling process and transportation of the material is allocated to this analysis. Cut-off criteria: All major raw materials and all the essential energy is included. The production processes for raw materials and energy flows with very small amounts (less than 1%) are not included. These cut-off criteria do not apply for hazardous materials and substances. Machines and facilities (capital goods) required for and during the production are excluded, as is transportation of employees. |
