Foundry
The foundry consisting of four lines may produce up to 50,000 tons billets a year.
The plant is particularly designed to cast billets of varied chemical compositions. The whole foundry charge is intended solely for our own manufacturing needs.
It is a special place at Grupa Kęty – the oldest manufacturing department of the whole Company, the germ of Grupa Kęty history and a cradle of our achievements in the processing of aluminium and its alloys.
In our foundry plant, we also have the technological capacity to produce billets in a way that allows lower carbon dioxide emissions.
Grupa KĘTY S.A. has obtained a Type III Environmental Product Declaration (EPD) certificate for profiles extruded from low-emission billets from its own foundry. These billets are produced from 6000 series alloys in the melting and casting line at the Kęty plant. The billets' low carbon footprint is due to the high share of aluminum scrap in the remelting process. In 2025, over 35,000 tons of waste were recycled at the plant. The plant selectively collects various types of scrap, thanks to which no fluxes adversely affecting the environment are used during secondary smelting. The process is accompanied by rigorous requirements as to the quality of purchased scrap, thanks to which no contaminated aluminium enters the smelting process, and harmful compounds that could pose a threat to the environment are not released into the air. By recycling aluminium, the plant saves significant amounts of energy needed to produce primary aluminium and reduces air and water pollution compared to producing aluminium from bauxite.
The carbon footprint of the profiles is just 2.31 kg CO2e/kg.
This is primarily due to:
- aluminum production through secondary smelting in our own foundry (95% lower energy consumption compared to aluminum production from bauxite);
- selective collection and an increase in the scrap share in the feedstock to over 75%;
- measures taken to increase energy efficiency and reduce energy demand in manufacturing processes and transport.
The values were determined based on the results of a product life cycle assessment (Life Cycle Assessment) in an environmental declaration compliant with the EN 15804 standard.
The document was verified by an external expert and has the status of a European "ECO-EPD verified" declaration. Additionally, the certificate has been posted on the ITB sustainable construction portal, making the profiles recognized in green building certification systems such as BREEAM, LEED, and DGNB.
Thanks to the certificate, we can provide our customers with products with verified ecological performance, allowing them to make informed choices.
This confirms Grupa Kęty's responsible approach to the environment and transparency in its operations. In addition to business goals, Grupa Kęty S.A.'s Development Strategy for 2025-2029 also outlines tasks supporting global trends in decarbonization and the circular economy.
