Aluminium scrap is the typical waste produced by the EPS. The scrap is a valuable material for the production of aluminium billets in the remelting process. For that reason, Grupa KĘTY recycles aluminium scrap and processes into billets from which profiles, tubes and bars are extruded. The Company utilises the aluminium scrap produced by the Capital Group, but also processes scrap originating from the market. The main waste produced by the ASS includes the remains from aluminium processing, sludge from sewage treatment and waste coating powders. The waste produced in packaging manufacturing at the FPS includes laminates, paper, aluminium foil, plastics, waste paints, lacquers and adhesives.

Waste produced is managed in accordance with the EU and Polish regulations, ensuring safety for the environment. Waste is collected selectively. Waste storage areas are separated from the ground, and waste is kept in special hermetic containers. The Company keeps quantitative and qualitative records. Waste which is not managed in-house is handed over to companies with the required licences. Waste management processes are monitored within the implemented environmental management system, in accordance with the ISO 14001 standard. With regard to waste collection, the Group cooperates solely with specially licensed companies.
Hazardous waste is transported in compliance with specific ADR requirements.
The percentage change in the total quantity of waste produced by Grupa KĘTY S.A. compared with the values for 2021 reached -9.6%. Nevertheless, the intensity of waste generation per ton of products grew by 4%. This is due to a change in production structure made in 2022, consisting in higher share of hard-alloy products. The manufacturing of those products and billets from which they are extruded causes a higher generation of waste per ton of product compared to soft-alloy products. The total intensity of waste production for domestic products dropped by 3.2%. At Grupa KĘTY S.A. the disposal of post-neutralisation sediment was eliminated, as the sediment recovery process was implemented. Consequently, practically all waste produced by the Company is subject to recovery.

Grupa KĘTY S.A. has in place the aluminium recovery process. Recycled is aluminium scrap generated by our production plants as well as scrap purchased from the market. The process is carried out at the Billets Production Department. Aluminium remelting is carried out in a battery of melting-and-casting induction furnaces (for hard-alloy billets) and gas furnaces (for soft-alloy billets). The plant selectively collects the particular grades of scrap. By recovering aluminium, the Company saves a lot of energy needed to produce primary aluminium. Compared with 2021, the quantity of remelted scrap dropped from 35,900 tons to 31,600 tons. Referring the values to production size, the intensity of recovery increased by 0.97%.
