Product information Product description The main product components, in the finished products, are shown in the table below as average fractions for all three declared gypsum boards. The maximum theoretical deviation from these fractions is <1 %. Due to rounding, the total weight-% is not exactly 100%. Material Flue gas desulphurization gypsum (FGD) Water (fresh + surface) Recycled gypsum Paper Additives Packaging material Wooden pallets (kg per declared unit) Weight-% of declared product 67,8% 21,0% 7,5% 3,1% 0,7% GKB Scan 12,5 mm 6,45E-02 GKB Scan Heavy 12,5 mm 7,93E-02 GKF Scan 15,5 mm 9,70E-02 Representativity This declaration, including data collection and the modeled foreground system including results, represents the production of the following gypsum boards for construction purposes: GKB Scan, 12,5mm; GKB Scan heavy, 12,5mm; GKF Scan, 15,5mm These gypsum boards are produced by Siniat B.V. at their manufacturing facility in Delfzijl, the Netherlands. Adding to this it should be noted that the GKB Scan 12,5 gypsum board is also available as the ‘GKB Scan 4AK 12,5’. The GKB Scan 12,5 has tapered edges only along its long side. The GKB Scan 4AK 12,5 also has tapered edges on its short side number. This declaration is representative for both. Data originates from annual accounts, product specifications, calculations and measurements. The data supplied by Siniat B.V. has been validated by LBP|SIGHT and checked for consistency and completeness. As such the data quality has been warranted. One-year average data has been collected for the year 2012. Because the manufacturing process has not changed, the data is still representative for the current practice at the manufacturing facility of Siniat in Delfzijl, the Netherlands. The environmental profile of specifically the flue gas desulphurization gypsum has been derived from a representative and published MRPI-Certificate (Dutch, third party verified, EPD format). Generic data has been utilized to model all other background data. The main source of this generic data is the EcoInvent database (version 2.2) with the exception of one specific process were the Dutch environmental database (NMD, version 1.7) was used. The generic data that is used is less than 10 years old. Dangerous substances It is stated by Siniat B.V. that the declared gypsum boards do not contain any substances listed in the ”Candidate List of Substances of Very High Concern for authorisation”.
