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.
Production of goods takes place at the Poznan plant, from where they are sent to the Sady plant. Similarly, production takes place at the factory in Cordoba, from where the products are sent to Sady or directly to customers. In Sady, packaging of products, storage and shipping to customers takes place. At the Pensnett plant, storage and shipping to customers takes place. Inputs were inventoried for each production and storage facility. The allocation of impacts is based on the weight of K65 series products, which is a percentage of total production/sales and transport and represents: 1.62% at the Poznan site, 0.23% at theSady site, 7.2% at the Pensnett site and 4.30% at the Cordoba site. Allocation to a single, representative product was made on the basis of product weight. All raw material receipts are allocated in module A1. Production is based on copper, and waste from production is sold as scrap to other parties where it will be recycled. Module A2 includes the transport of semi-finished products between the production sites Poznan - Sady, Cordoba - Sady, Sady - Pensnett. Energy consumption, fuel consumption and waste were inventoried for the entire production process in module A3.
100% of input materials and 100% of electricity, natural gas, propane and diesel and water consumption were inventoried at the Poznan, Sady, Cordoba and Pensnett plants. All relevant parameters from the collected production data are included in the assessment, i.e. all materials consumed for production, packaging materials and utilities used, waste produced and emissions generated.
