| Use advice for data set | Scope: The EPD covers 100% of the production of laminated safety glass by Glas Trsch Holding AG at the plants in Osterweddingen (D), Haldensleben (D) and Ujazd (PL). System boundary: Type of EPD: "from the cradle to the factory gate with modules C1-C4 and module D (A1-A3, C and D)". In the manufacture of 2-pane laminated safety glass (modules A1-A3), 2 panes of flat glass, each 3 mm thick, are bonded with a PVB film. LSG is usually loaded onto metal racks that are often reused; accordingly, only small quantities of packaging material are produced - if any at all - that have to be disposed of. In connection with the modeling of the production of flat glass, the following system limits were assumed in terms of the "end ofwaste" status: Cullet is considered a "product" according to REGULATION (EU) No. 1179/2012 of December 10, 2012. Broken glass has reached "end of waste" status when it is available as sorted cullet. External cullet enters the product system as sorted cullet and is therefore a "secondary material" according to EN 15804. No secondary fuel is used as input for the modeling. Due to the negligible quantity, the content of biogenic carbon in the packaging is not explicitly taken into account when quantifying the "GWP" indicator (according to the cut-off criteria). Modules A1-A3 of the production stage comprise the manufacture of the products, including raw material extraction and processing, energy generation, the manufacture of by-products and packaging materials, and all waste treatment processes. Module A4 is not declared, as declared glass is first transported to processors and then on to the construction site; accordingly, the transports must be declared in EPDs for the products in which laminated safety glass is used. No inputs and outputs are attributed to the actual installation in order to avoid double counting by the user of laminated safety glass. Laminated safety glass is generally loaded onto metal racks that are often reused; accordingly, only small quantities of packaging material - if any - are produced that need to be disposed of; module A5 is therefore not declared. The maintenance (module B2) of the laminated safety glass, namely its cleaning, is not declared, as it depends heavily on the area of application of the laminated safety glass. These inputs and outputs must be taken into account in the declaration of the product in which the laminated safety glass is installed. Two scenarios are declared in the end-of-life: Scenario 1, recycling: the utilization of the deconstructed glass as a gravel substitute; Scenario 2, disposal: landfilling in an inert material landfill.As dismantling takes place at the end of life of the final product, module C1 is not declared. Module C2_1 comprises the transportation of the laminated safety glass (installed in a product) over 50 km to a sorting plant for building materials. Module C2_2 comprises the transportation of the laminated safety glass (installed in a product) over 50 km to an inert material landfill. Module C3_1 describes the processing of the laminated safety glass into gravel substitute for scenario 1. Module C4_2 describes the landfilling of the laminated safety glass for scenario 2. Module D_1 describes the avoidance of the extraction of primary gravel for scenario 1, whereby a net flow calculation is carried out in relation to the input and output of cullet. No credits result from the landfilling of the laminated safety glass. The declaration of benefits from the recycling of minimal quantities of waste from production or minimal quantities of packaging from transport packaging is neglected in both D-modules. The corresponding residual mixes from the ecoinvent v3.9.1 database are used, whereby the Osterweddingen plant purchases certified electricity from renewable sources. | ||
| Technical purpose of product or process | Laminated safety glass is the starting material for the manufacture of a wide range of products, not only in the construction industry. These include their use as windows or faade elements in the building envelope or in the expansion of buildings and structures. | ||

| General comment on data set | Laminated safety glass (LSG) consists of at least two superimposed panes of float glass and one or more layers of a tear-resistant and viscoplastic film between the panes, which is usually made of polyvinyl butyral (PVB). Laminated safety glass binds splinters in the event of glass breakage and thus significantly reduces the risk of injury. In addition, laminated safety glass offers a significantly improved residual load-bearing capacity compared to float glass in the event of glass breakage. This EPD applies to the following products: Product name and build-up of the LSG EUROLAMEX 6.1 33.1 (declared as representative product) EUROLAMEX 6.2 33.2 EUROLAMEX 8.1 44.1 EUROLAMEX 8.2 44.2 EUROLAMEX 8.4 44,4 EUROLAMEX 10.1 55.1 EUROLAMEX 10.2 55.2 EUROLAMEX 12.1 66.1 EUROLAMEX 12.2 66.2 EUROLAMEX 16.1 88.1 EUROLAMEX 16.2 88.2 | ||

| Technology description including background system | In the production of laminated safety glass, float glass panes are bonded together using a PVB film in an autoclave under the influence of heat and pressure, with variations possible in the thickness of the glass or film, the type of glass and the number of panes bonded together. In the construction sector, laminated safety glass consisting of 2 panes (and a PVB film) is usually used. All sites where float glass and laminated safety glass are manufactured are certified to ISO 9001. Declared unit: Laminated safety glass VSG EUROLAMEX 6.01 (2 panes of float glass 3 mm, 1 PVB film of 0.38 mm) is declared as the best-selling and therefore representative product in the construction industry. | ||
