At the Capital Group companies process and household wastewater originates. Supervision and monitoring of the wastewater production and discharge limits its negative impact on the environment and potential risks. At the EPS, Grupa KĘTY S.A. and its subsidiary AK EMMI discharges wastewater directly to surface waters. Security measures have been taken at the companies to prevent the possible spills. The wastewater is discharged based on a water permit possessed. The quality of the discharged wastewater is tested at regular intervals by accredited laboratories. The permit conditions have been met. The treatment systems are fit with specially-designed pretreatment solutions serving neutralisation of specific types of wastewater originating in the processes of aluminium surface working.
At the ASS, wastewater is discharged directly to surface waters only by ROMB S.A. The wastewater is produced at the electroplating shop and in the processes of steel and aluminium elements cleaning, after treatment. The other companies of the ASS and the FPS companies discharge wastewater, after pre-treatment, to the sewer systems of third-party companies.
Compared with 2021, there was a reduction of 29%. The reduced quantity results from optimisation of the process
of aluminium products chemical treatment and production size limitation. The quantity of wastewater discharged
by the domestic companies to third-party sewer systems dropped by nearly 8%.
In 2022, no excesses were recorded at companies discharging wastewater to surface waters. The objective for all companies of the Capital Group is to maintain wastewater parameters at the lowest possible level, and optimise production processes with regard to wastewater origination.
