Fossil fuel for building machinery and auxiliary materials SUBSTANCES, REACH - VERY HIGH CONCERN are included. The product does not contain any REACH SVHC substances in PRODUCT USE AND MAINTENANCE (B1-B7) amounts greater than 0,1 % (1000 ppm). This EPD does not cover use phase. Air, soil and water impacts PRODUCT LIFE-CYCLE during the use phase have not been studied. PRODUCT END OF LIFE (C1-C4, D) MANUFACTURING AND PACKAGING (A1-A3) At the end-of-life, in the demolition phase, 100% of the waste is assumed to be collected as separate construction waste (C1). All of The prefabricated filigree concrete slab manufacturing begins with the end-of-life product is assumed to be sent to the closest facilities the preparation of the mould. This includes assembly of the mould (C2). depending on the element dimensions, cleaning of the mould and 100% of steel and 92% concrete is recycled (C3) and the remaining application of the form oil. The reinforcement and steel details are is sent to a local landfill for disposal (C4). Due to the recycling then put in place according to the technical element drawing. Wet potential of reinforcement steel and concrete, the end-of-life product concrete is then poured into the mould and vibrated into place, and is converted into recycled raw materials (D). surface finished. After casting, the slab is covered and cured. After curing the slab is then demoulded and moved out of the factory. Eventually, it is transported to the construction site. 4 Environmental Product Declaration created with One Click LCA PRECAST CONCRETE FILIGREE SLABS MANUFACTURING PROCESS BIOGENIC CARBON CONTENT Neither the product itself nor the packaging contains biogenic carbon, so the biogenic carbon content at the factory gate is 0 kg.

DECLARED AND FUNCTIONAL UNIT Declared unit 1 tonne Modules not declared = MND. Modules not relevant = MNR. Mass per declared unit 1000 kg 5 Environmental Product Declaration created with One Click LCA PRECAST CONCRETE FILIGREE SLABS The study includes all major raw material and energy consumption. All inputs and outputs of the unit processes which data are available for are included in the calculation. There is no neglected unit process more than 1% of total mass and energy flows. The total neglected input and output flows do also not exceed 5% of energy usage or mass. The life cycle analysis includes all industrial processes from raw material acquisition to production, distribution and end-of-life stages. Packaging does not include any biogenic carbon as product is only packaged using reusable tie down straps. The production of capital equipment, construction activities, and infrastructure, maintenance and operation of capital equipment, personnel-related activities, energy, and water use related to company management and sales activities are excluded. The modules B1-B7 have not been calculated nor included in the LCA calculations as that is not mandatory for this LCA report. ALLOCATION, ESTIMATES AND ASSUMPTIONS The allocation is made in accordance with the provisions of EN 15804. Allocation is based on the annual production rate. Heat, electricity and other energy use in production, are calculated as a CUT-OFF CRITERIA weighted average per produced tonne of all products using yearly production data and rate for 2019. The study does not exclude any modules or processes which are stated mandatory in the EN 15804:2012+A2:2019 and RTS PCR. The Carbonation is not taken into account in the calculations. Carbonation study does not exclude any hazardous materials or substances. is a natural process occurring when carbon dioxide is emitted during cement production is rebound to the concrete during the use and 6 Environmental Product Declaration created with One Click LCA PRECAST CONCRETE FILIGREE SLABS end of life stages of a building. The average distance of transportation from the production plant to building sites in Sweden, Norway, Denmark and UK and the fill rate As the raw material use for each of the products produced in the to be 100%: factory is recorded to a high standard of accuracy and precision, the For transportation to building sites in Sweden it is assumed that raw material data for each of the products produced is processed. 335 km of the total distance are covered by a lorry and it is assumed From the data, the most likely product size, thickness and that 275 km of the total distance are covered by a ferry. reinforcement amount is chosen and thus it is assumed to be the most representative product of the annually produced products of For transportation to building sites in Norway it is assumed that the same kind. Since the production and transportation processes 655 km of the total distance are covered by a lorry and it is assumed are similar for all of the products produced in the factory, the energy that 275 km of the total distance are covered by a ferry. consumption is allocated according to the annual production of the declared unit to the total annual production at the factory.
