Besides aluminium, purchased electronic components and non-production materials have the greatest impact. Preliminary calculations show a total amount in 2022 of 341,567 tonnes of CO2 equivalents, which were generated during the production of purchased materials and the use of services. In contrast to the previous year, the volume of emissions decreased slightly while purchasing volumes remained roughly the same (2021: 359,171 tonnes), due to improved quality of data, particularly in the area of non-production materials. The material-related CO2 emissions will be included in the calculation of the PCF. Use of aluminium The environmental impact of primary aluminium is significantly higher than that of remelted secondary aluminium. Since 2019, we have been recording the proportion of secondary aluminium in our internationally procured aluminium volume in order to be able to identify positive or negative developments. The high proportion of secondary materials at 78 per cent was able be upheld with a slight decline in procurement volumes in 2022 (2022: 17,251 tonnes, 2021: 18,275 tonnes). In 2022, we succeeded in determining the CO2e footprint of aluminium cast parts for the first time on an alloy- and country-specific basis. As a result, the associated emissions have increased significantly, so that a total of 90,815 tonnes were emitted from aluminium (2021: 69,393 tonnes). As aluminium is our most important raw material, we are working to keep this raw material in circulation. Options for reprocessing aluminium briquettes at our Hungarian plant and for procuring aluminium produced with renewable energy are currently being examined. GRI 301-2 Sustainable procurement Festo’s purchasing structure is characterised by the procurement of semi-finished products, components and finished parts. Aluminium, (stainless) steel and plastics are amongst the most important materials. The products purchased by Festo have an ecological effect on several levels. In addition to the finite nature of resources, the consequences of raw material extraction and the resulting CO2 emissions must be taken into account. The quantities of materials purchased in 2022 in tonnage have been visualised in the diagram below. GRI 301-1 More than half of the raw materials purchased for the manufacture of our products consist of primary and secondary aluminium. Around 22 per cent are made of steel or stainless steel, 19 per cent are plastic granules or parts and 4 per cent are other metals. Furthermore, prefabricated electrical components and electromagnets are used. In addition to production materials, non-production materials such as vehicles, IT infrastructure and operating materials as well as services must be taken into account. The aluminium supply chain begins with the mining of bauxite. The raw material for aluminium production has adverse effects on the environment depending on the mining region. The great economic importance and the supply risk of bauxite lead to bauxite being declared a critical raw material by the European Union in 2020. The procurement of secondary aluminium saves a significant proportion of emissions and protects bauxite stocks. GRI 2-6, GRI 301-2, GRI 304-2 The reprocessing of aluminium briquettes offers great savings potential. 80 81 Festo SE & Co. KG Sustainability Report 2022 Festo SE & Co.
