Effluents

In addition to PKN ORLEN, the following companies operate their own wastewater treatment facilities: ANWIL, Ship-Service, Spolana, Paramo, Unipetrol, ORLEN Lietuva and ORLEN Południe. All wastewater reaching the wastewater treatment plants undergoes a multi-stage treatment process which includes mechanical, physical, chemical and biological treatments. Once wastewater is treated in accordance with the Company’s integrated permits, it is discharged into rivers: Vistula, Elbe, Oder, Vltava, Jasiołka, Bílina, Dubulis, and to the Baltic Sea.

The other companies divert their wastewater streams to sewage systems of other Group companies or third parties. The volume of effluents treated by third-party operators was 1,080,662 m³. The ORLEN Group does not use rainwater collected directly or treated wastewater generated by entities from outside the Group.
