| Use advice for data set | Scope: This EPD applies for Fibrolith® lightweight panels (lightweight panels as plaster base boards and stable ventilation panels) manufactured in the Fibrolith® Dmmstoffe GmbH plant in Kempenich (Germany). System boundary: Type of EPD: from the cradle to the factory gate with options, i.e. modules C1-C4 and module D (A1-A3, C, D and additional modules. The additional modules may be A4 and/or A5 and/or B1-B7). Transport to the construction site (module A4) is not modelled and must be taken into account on a case-by-case basis in a building assessment. Manual installation is assumed for installation in module A5; the electricity consumption for installation (cordless screwdriver) and fasteners (dowels/screws) is not taken into consideration. Disposal of the packaging is modelled in module A5, whereby cardboard is recycled and the polyethylene or wood packaging is thermally recycled in a waste incineration plant. During use (module B1), the binder in the wood wool panels carbonates, which absorbs CO2 from the atmosphere. In general, all panels can be reassembled and reused after dismantling. If the panels are damaged or can no longer be used, single-layer panels can be thermally utilised. For dismantling, manual dismantling is assumed in the same way as for installation; the electricity consumption for dismantling (cordless screwdriver) is not taken into consideration; the values in module C1 are therefore zero. The panels are transported to a waste incineration plant in module C2. The mono-panels are recycled thermally in a waste incineration plant in module C3. The benefits and loads outside the product system (module D) include the exported energy from the energy recovery of the packaging in module A5 and from the energy recovery of the mono-panels (module C3). The exported electricity replaces the German consumption mix and the exported heat replaces the heat from a gas firing system. | ||

| Technology description including background system | Bereits entrindete Fichtenholzstämme mit 2m Länge werden nach ihrer Anlieferung 6 bis 12 Monate gelagert, bis ihre Restfeuchte auf 27 % gefallen ist. Anschließend werden sie mechanisch zu Holzwolle verarbeitet. Die Holzwolle wird angefeuchtet und in einem Zweiwellenmischer mit dem Portlandzement vermischt. Das entstandene Mischgut wird in Formen gestreut, mehrmals gepresst und gestapelt. Die Stapel werden mit einem Gewicht belastet und zum ersten Aushärten gelagert. Nach etwa 24 Stunden hat der Zement durch den Abbindeprozess eine ausreichende Festigkeit erreicht, damit die Platten ausgeschalt werden können. Anschließend werden die Platten nochmals mehrere Tage stehen gelassen, damit der Zement fester werden kann, um dann in einem gasbetriebenen Trockenofen die Restfeuchte zu entfernen. Abschließend werden die getrockneten Platten konfektioniert und bei Bedarf noch lackiert oder direkt zum Versand verpackt. Die deklarierten fibrolith® zementgebundene Holzwolleplatten (Monoplatten) bestehen aus: Fichtenholz: 40% - 50% Portlandzement: 24% - 52% Wasser: 8% Abbindebeschleuniger <0,1% Das Fichtenholz wird aus nachhaltiger und PEFC- bzw. FSC-zertifizierter Forstwirtschaft bezogen. Der Weißzement dient als Bindemittel, damit die Platten die notwendige Stabilität erreichen. Wasser wird größtenteils als Kristallwasser im Zement gebunden, verbleibt aber auch zu einem geringen Teil als Restfeuchte in der Platte. Der Abbindebeschleuniger reduziert die notwendige Abbindezeit des Zements. Declared unit: The declared unit is one tonne Fibrolith® lightweight panels (lightweight panels as plaster board bases and stable ventilation panels). | ||
