General comment The data for the LCA calculation of modules A1-A4 came from verified LCI inventory data from the plant. In accordance with Annex E of EN 15804 + A2, a data quality assessment was carried out. For technical representativeness, processes with a quality level of 'very good' represent 99% of the values for the climate change indicators. For geographical and temporal representativeness, a process evaluation level of "very good" was obtained.
Semi-finished and finished products come to Sady from the factory in Poznan (Poland) and the factory in Yuhuan (China). Semi-finished products are assembled and packaged at Sady and shipped directly to customers or to storage facilities in Cordoba and Pensnett, from where they are distributed further to customers. Inputs were inventoried for each production (Poland, China) and storage facility (Poland, Spain, UK). The allocation of impacts is based on the weight of brass products, which is a percentage of total production and transport and represents: 0.036% at the Poznan site, 0.37% at the Sady site, 6.55% at the Pensnett site, 2.73% at the Cordoba site and 6.60% at the Yuhuan site. The allocation to a single, representative product was based on product weight. All raw material receipts are allocated in module A1. Production is based on brass and bronze ingots, and waste from production is sold as scrap to other operators where it will be recycled. Module A2 includes the transport of semi-finished products between the production sites: Yuhuan - Sady, and the production plant and storage facilities: Sady - Cordoba, Sady - Pensnett. Energy consumption, fuel consumption, water consumption and waste production were inventoried for the entire production process in module A3.
100% of input materials and 100% of electricity, natural gas, propane, diesel and water consumption were inventoried at the Poznan, Sady, Cordoba, Pensnett and Yuhuan plants. All relevant parameters from the collected production data are included in the assessment, i.e. all materials consumed for production, packaging materials and media used, waste produced and emissions generated.
