| Use advice for data set | Scope: This document refers to 1 m of Heradesign Fine Alpha+ 35 mm (Euroclass B) with a surface weight of 17.5 kg/m manufactured at the production facility in Ferndorf (Austria). The product is a magnesite bonded wood wool panel. System boundary: The life cycle assessment of Heradesign acoustic panels includes a cradle-to-gate analysis of the environmental impacts with modules C1–C4 and module D (A1–A3, + C + D). Subsequent life cycle phases are part of the analysis: Module A1–A3 | Production stage The production stage includes upstream burdens of raw materials (wood, binding agents, recalcination, auxiliaries, etc.) and the corresponding transports to the production site in Ferndorf (Austria). Material and energy flows needed for the mixing of the components, scattering and shaping, interim storage and picking as well as dyeing and packaging were specifically recorded. In addition, the recalcination process for the provision of Knauf Sekundrkauster is considered. The representation of all specific input and output flows is thus based on company-specific foreground data. 100 % green electricity is used in the production. Thermal energy results from energy recovery from the recalcination process supplemented by natural gas. The production of the acoustic fleece laminated to the back of the Heradesign panels is declared in a separate appendix to the EPD. Module C1 | Deconstruction and demolition Disassembly of the product is done either manually or using smaller tools. Referring energy demand is considered to be negligible. Module C2 | Transport to disposal The transport to the disposal of the material is estimated declaring a 50 km radius to the landfill. In reality, this scenario may vary depending on the actual location of deconstruction and referring waste treatment. Module C3 | Waste processing The declared scenario assumes landfilling of the product. Referring environmental impacts are accounted for in module C4. Therefore, no environmental impacts from waste processing of the product are expected in C3. Module C4 | Disposal Modul C4 declares the environmental impacts from landfilling after use of the product. The biogenic carbon in the wood share of the product is treated as emissions of biogenic CO2 from the technosphere to the natural environment. Module D | Benefits and loads beyond the system boundary The declared scenario assumes landfilling of the product. Referring environmental impacts are accounted for in module C4. No benefits or loads outside the system boundary in Module D are to be expected. | ||

| Technology description including background system | 2.6.1 Raw material Spruce wood is stored as trunks 2 metres in length. Depending on climate conditions, storage lasts around 6-12 months. The trunks are transported by conveyor belts to a multi-rip saw, cut into pieces and processed as wood wool using a planing machine. The binding agent components are stored in steel silos. 2.6.2 Mixer Wood wool, as well as a binding agent and a magnesium sulphate solution, are required for generating a mixture for wood wool pellets. These components are transported to a mixer where they are processed to form the requisite formula. 2.6.3 Scattering and shaping The mixture is scattered onto a steel band and passed through a binding channel, whereby it is separated from the room by a second horizontal steel strip as well as two side strips. An endless product is produced on leaving the twin belt. The raw goods are then cut to the desired length. 2.6.4 Interim storage and picking The products are put into interim storage for 3-5 days (drying and maturing process). The requisite edge design is then produced on so-called double-end profiling machines. Edge processing: 18 standard edges are possible. 2.6.5 Dyeing, packaging and shipping The requisite colour is applied in a dyeing plant, followed by packaging and storage. Dyeing: Possible in many RAL colours (left) Products ready for storage (right) Technical data: Product-specific values can be found at http://www.knaufceilingsolutions.com Declared unit: This EPD refers to a declared unit of 1 m of Heradesign Fine Alpha+ 35 mm (Euroclass B). The declared unit refers to a surface weight of 17.5 kg/m. | ||
