The product is used for general indoor building construction of walls and ceilings.The Nordic Countries: Denmark, Norway and Sweden.gypsum plasters or decoration may be applied). The mass of the declared unit is 6.7kg and the thickness is 12.5mm.The range of the products carrying the name Knauf Light Board includes products with different edge profiles such as square and beveled edges. This EPD is valid for all variations carrying the Knauf Light Board name, measuring 900 x 2400 x 12.5mm or 900 x 2700 x 12.5mm, with designated name 13 B-1.5.3330.91313.63* In total, 3623kg of water is consumed during the production process. Due to mainly the solidification of the gypsum, 2710kg ofwater is evaporated during the production process.The gypsum used for stucco in the Knauf plasterboard production originates from mined gypsum (1 % in 2013), FGD gypsum from flue-gas desulphisation in coal power plants (81.2 % in 2013) and recycled gypsum (17.8 % in 2013). The recycled gypsum originates from internal waste and from external collection of used gypsum plasterboards.0.024580.004The internal recycling of gypsum boards in the Knauf factory started in 1991, and since 2004 all internal gypsum waste has beenrecycled and used. In 1998, Knauf started to use recycled gypsum from gypsum plasterboards collected from building sites.kg%1.350.044.780.040.0910.00260.320.17579.600.606.71000.23/8 ���������������������������������
LCA: Calculation rulesDeclared unit:System boundary:Figure 1: A flow diagram showing the value chain and the system boundaries.Data quality:Cut-off criteria:Allocation:1m2 of Light Board, from raw material extraction (A1) to the factory gate (A3).The data requirements are according to PCR 010 rev1 Building Boards (12 2013) clause 7.3.6. Specific data collected from contractors is applied for the most important raw materials in A1. Specific data from the 2013 production at the manufacturing site is applied in A3. Missing data were substituted with generic data from Ecoinvent v2.2 (2010) and v3.1 (2014). No data are more than 5 years old.Figure 1 shows a flow diagram of the value chain, including the system boundaries from A1 - C4. Biogenic carbon is also included in the system boundaries.The allocation is made in accordance with the provisions of EN 15804:2012. Energy and water consumption in the factory is allocated to the FU through mass allocation. The water consumption is allocated to module A3 and only includes direct factory use, upstream water use is not included. Waste production in the factory is allocated on the basis of m2. Effects of primary production of recycled materials is allocated to the main product in which the material was used. The recycling process of the Knauf Light Boardis allocated to module C3.All major raw materials and all the essential energy is included. General cut-off criteria are given in standard EN 15804:2012 clause 6.3.5. In compliance with these criteria, the infrastructure of the manufacturing site, small parts of the packaging and the electricity used to fasten screws are excluded from the study. No potentially hazardous materials have been excluded.1. Quarry, natural gypsum2. Power station, flue gas gypsum3. Paper factory, face and back liner4. Recycled paper5.

The LCA results of the other products in the Knauf Light Board product range are estimated to be between 0 and 5% lower than theresults below. When interpreting the results, it is important to note that a 15% product loss is accounted for in A5, that A3 energy consumption is composed of Danish el-mix and natural gas, and that mass of the declared unit is 6.7kg.The GWP includes biogenic carbon uptake and emissions, calculated according to EN 16485:2014 whereby 0.467kgCO2 is taken up in A1 and emitted again in C3 and C4, so that the net value is zero within the system boundaries.Raw materialsA1TransportA2Beyond the system boundariesTransportxRepairRefurbishmentMNRxDe-construction demolitionC3x0,22Product stageOperational energy useB7AssemblyB6A31,371,6E-07POCPkg C2H4 -eqvADPEParameter1,1E-032,8E-0616,40,182,7E-082,6E-057,4E-041,1E-042,0E-039,2E-041,0E-06A4 NODPA21,8E-036,0E-045,9E-07A5C1C4GWP Global warming potential; ODP Depletion potential of the stratospheric ozone layer; POCP Formation potential of troposphericphotochemical oxidants; AP Acidification potential of land and water; EP Eutrophication potential; ADPM Abiotic depletion potential for non fossil resources; ADPE Abiotic depletion potential for fossil resourcesMJkg SO2 -eqvAPMNRxxUnitEPADPMkg PO43--eqv9,7E-07xxxGWP5,07E-0721,3A4 D1,2E-04kg Sb-eqvTRPEA1Unitkg CFC11-eqvxMJRPEEUseA4B1MJNRPMRPEMTPEkg CO2 -eqv-0,033,8E-08NRPEMJParameterMJMJDDisposalReuse-Recovery-Recycling-potentialC4xWaste processingC4C2MNDTransportxC2C3kgMJMJm3SMRSFWNRSFRPEE Renewable primary energy resources used as energy carrier; RPEM Renewable primary energy resources used as raw materials; TPE Total use of renewable primary energy resources; NRPE Non renewable primary energy resources used as energy carrier; NRPM Non renewable primary energy resources used as materials; TRPE Total use of non renewable primary energy resources; SM Use of secondary materials; RSF Use of renewable secondary fuels; NRSF Use of non renewable secondary fuels; W Use of net fresh waterINAINAINAINAINAINAINAINAINAINAINAINAINAINAINAINAEnd of life stageB5C11,28MJxReplacementxxAssemby stageB3A3Operational water useMaintenanceA5B2B4ManufacturingUse stageINA2,92E-03INA6/8 ���������������������������������
