| Use advice for data set | Scope: This document refers to 1 m Classic Max mineral ceiling tiles with a surface weight of 3.76 kg/m, manufactured at the production facility in Wujiang, China. System boundary: The life cycle assessment of Classic Max mineral ceiling tiles includes a cradle-to-gate analysis of the products environmental impacts with modules (A1–A3, C, D). Subsequent life cycle phases are part of the analysis: Module A1–A3 | Production stage The production stage includes the upstream burdens of raw material supply, their transports and the manufacturing plant of Knauf Ceiling Solutions located in Wujiang (China). Mineral ceiling tiles are produced in the wet-felt process. Main raw material inputs, therefore, refer to mineral wool, perlite, clay and starch. The production site is supplied with electricity from the Chinese power grid and thermal energy from natural gas. 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. Modul 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. Module C4 | Disposal Module C4 refers to the emissions from the disposal of the acoustic board mineral ceiling tiles. The chosen scenario, therefore, includes the environmental burdens of landfilling the product. 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. | ||
| Technical purpose of product or process | Mineral tiles (wet-felt) are typically used as lay-in for suspended ceiling constructions. They are primarily used as optical cladding, but also for sound absorption and sound insulation, for fire resistance and against fire spreading, for cleanrooms and high hygiene requirements. | ||

| General comment on data set | The ceiling tiles are manufactured using a wet-felt process and consist of biosoluble mineral wool, perlite, clay and starch. In addition, the visible side of the mineral tile is painted with dispersion paint. The back side is primed with dispersion paint. The mineral tiles are available in different formats and edge finishes. This EPD applies to the following products: Classic Max | ||

| Technology description including background system | The mineral tiles are produced in the traditional wet process (wet-felt). The raw materials are mixed with water to form a homogeneous suspension, which is pumped onto a belt conveyor (Fourdrinier). The water is removed mechanically (gravity and vacuum) and by evaporation in the drying oven. As far as possible, the process water is reused. It is treated accordingly and fed back into the process water circuit. Production waste and dust are reused in the process in the sense of an internal cycle. The manufacturing plant is certified according to ISO 9001, ISO 14001 and ISO 45001. Declared unit: This EPD refers to a declared unit of 1 m Classic Max mineral ceiling tiles with a surface weight of 3.76 kg/m. | ||
