3.4 Cut-off criteriaCriteria for the exclusion of inputs and outputs (cutoffrules) in the LCA and information modules andany additional information are intended to supportan efficient calculation procedure.All inputs and outputs to a (unit) process are includedin the calculation, for which data were available.The applied cut – off criteria is 1 % of renewableand non-renewable primary energy usage and 1 %of the total mass input of that unit process in case ofinsufficient input data or data gaps for a unit process.The total of neglected input flows per module, e.g.per module A, B, C or D is a maximum of 5 % of energyusage and mass.3.5 Background dataBackground processes are taken from the publiclyavailable professional GaBi 4.4 databases as far asavailable (GaBi DOC 2010). Country and regionspecific data on energy sources including electricityand region specific data on raw materials such aslimestone and clay were taken from GaBi databases.3.6 Data qualityThe process data and the used background data(GaBi DOC 2010) are consistent. In addition, theorigin of the data is documented. Additional informationis gathered regarding the age of the data.The input and output data of the whole processplant was strongly emphasized. The supplied data(processes) were provided by Eczacıbaşı BuildingProducts Co. and checked for plausibility.Therefore, the data quality can be described asgood.The age of the data employed in this study is due to2010.3.7 Period under reviewThe period under review is defined as one year. Themonthly data is collected by the producer and is averagedto obtain the yearly data. As explained here,the average data for the year 2010 is utilized withinthis study.3.8 AllocationIn this study, allocation was avoided wherever possibleas required in FprEN 15804.Many different products are produced at the productionplant of Eczacıbaşı Building Products Co.located in Bozüyük, but as all products undergo thesame manufacturing process and as they are verysimilar in terms of material composition, all themanufactured products are classified as two productgroups: Vitreous china and fine fireclay. Each ofthese product groups are modeled separately,which means that in each model there is only onesingle product group As a result of this situation, co– product allocation becomes unnecessary as thereare no co – products existing.4 LCA: Scenarios and additional technical informationThe modules A4, A5, B1, B2, B3, B4, B5, referenceservice life, B6, B7 and C1 – C4 are not consideredand declared in this study.5 LCA: ResultsDESCRIPTION OF THE SYSTEM BOUNDARY (X = INCLUDED IN LCA; MND = MODULE NOT DECLARED)PRODUCT STAGE3.9 ComparabilityBasically, a comparison or an evaluation of EPD datais only possible if all the data sets to be comparedwere created according to FprEN 15804 and thebuilding context, respectively the product-specificcharacteristics of performance, are taken into account.CONSTRUC-TIONPROCESSSTAGEUSE STAGEEND OF LIFE STAGEBENEFITS ANDLOADSBEYOND THESYSTEMBOUNDARYSRaw material supplyTransportManufacturingTransportConstruction-installationprocessUseMaintenanceRepairReplacement 1)Refurbishment 1)Operational energy useOperational water useDe-constructiondemolitionTransportWaste processingDisposalReuse-Recovery-RecyclingpotentialA1 A2 A3 A4 A5 B1 B2 B3 B4 B5 B6 B7 C1 C2 C3 C4 DX X X MND MND MND MND MND MND MND MND MND MND MND MND MND MND6 Environmental Product Declaration Eczacıbaşı Building Products Co. – Vitreous China Ceramic Sanitaryware

This situation arises due to the use of naturalgas and electricity as energy source. Natural gas asa fossil fuel constitutes the major non renewableenergy source. Electricity also contributes to the nonrenewable resource usage because of the distributionof energy resources employed in generation ofthe power grid mix.There is no secondary material use in the manufacturingprocess of vitreous china ceramic sanitarywareproducts.The energy sources used in the production plant arenatural gas and electricity. There are no other additionalenergy resources used in the productionplant. Since in upstream processes no secondaryfuels are used, there is no input regarding renewableand non - renewable secondary fuels.The net fresh water use for vitreous china ceramicsanitaryware products is 19.4 m 3 per 1 t of product.Nearly the half of this water use arises due to preprocessesof the power grid mix. The other contributorsof this parameter are water utilized during manmanufacturingand the water usage for the pre –processes of the raw materials.Although radioactive compounds are not used in themanufacturing process itself, a small amount of radioactivewaste appears on the balance table. Thissmall amount arises due to the power grid mix andpre – processes of raw materials used in main manufacturingand packaging processes.All the impact categories except for ADPE and ODPare dominated either by natural gas utilization or thepower grid for vitreous china ceramic sanitarywareproducts.The environmental impact of the ADPE parameter ismainly generated because of the raw materials usedduring the main production process, the mouldingprocess and the packaging process such as zincoxide, gypsum and glue. Through the examinationof the ODP parameter it can be observed that theimpact generated in this category is sourced mainlyby polyurethane employed in the moulding process.Environmental Product Declaration Eczacıbaşı Building Products Co. – Vitreous China Ceramic Sanitaryware 7
