binderholz CLT BBS SYS 125 Note: this EPD includes two distinct end-of-life scenarios. - EPD 1ab105d9

binderholz CLT BBS is a solid wooden construction element in panel form that consists of softwood layers that are glued together at right angles to each other.Calculation rules: Declared unit The declared unit for the life cycle assessment is 1 m³ of binderholz CLT BBS SYS 125 (with a mass of 467 kg/m³ and a wood moisture content of 11 % ± 2 %) Reference service life The reference service life (RSL) differs per application. Per sfB-code is the RSL provided follow the SBR Refrence service life of construction products: • External wall, constructive has a 100 year RSL. • Interior wall, constructive has a 100 year RSL. • Floor, constructive has a 75 year RSL. • Stairs and slopes has a 50 year RSL. • Roof, constructive has a 100 year RSL. • Columns and beams has a 100 year RSL. • Supporting structures, walls and floors has a 75 year RSL. Data collection Input- and output data has been provided by binderholz of the production year 2021 for the following inventory categories: • Materials (raw materials and auxiliary materials); • Energy (electricity and heat); • Emissions to air, water and soil. Allocations The material and energy needed has been determined by allocating the total needed energy/materials of 2021 for the CLT BBS to the total amount of CLT BBS produced in cubic meters. During the production of the CLT, other products are produced as well. An economic allocation is done to attribute the impact of the production to the respective products in modules A1, A2 and A3. The impact allocated to the CLT of the product stage is 98,4% Cut-off criteria This LCA contains all relevant data. The following processes are not included in this LCA: • Assumed is that the maintenance and use of auxiliary equipment have a negligible contribution to the total (<1%). Because of this, these processes are not taken in account in this LCA, except such processes that are included in the Ecoinvent background data. • Assumed is that the capital goods and infrastructure processes have a negligible contribution. These processes are not taken in account in this LCA, except such processes that are included in the Ecoinvent background data. There is no reason to believe that relevant in- or outputs are excluded from this study.Scenarios and additional technical information Product stage (A1-A3) This stage consists of the extraction of raw materials, energy which occurs upstream to the manufacturing process, transportation of raw materials, processing of the raw materials into the final product with all processes and energy required for production as well as packaging materials. The binderholz CLT BBS SYS 125 consist of softwood as well as 1-K-PUR and MUF adhesives. Data collection was performed by Binderholz Bausysteme GmbH in cooperation with some suppliers. The manufacturer compiled mass and energy balances based on average production in year 2021. The production facility in Unternberg buys renewable electricity. The data collection of the capital goods in the production facilities has been allocated based on mass output of products. For the cultivation of wood, no primary data could be obtaines as the sources are from several suppliers.Declaration of SVHC: No substances of very high concern are present in concentrations greater than 0.1% by weight in the product.More information: https://www.binderholz.com/en-us/products/clt-bbs/

EPD structure This EPD for the CLT of binderholz contains two datasets: one scenario follows the NMD waste scenario; and one scenario is for 100% reuse. As the construction industry is increasingly focussing on having circular products that can be reused, a scenario with 100% reuse is presented in the results here. These results can only be used if reuse in the end-of-life scenario can be guaranteed.
