The flue gases are purified intensively in successive installations to meet the strict emission standards.

Electro filters remove the fly ashes.

Raw materials such as lime and an adsorbent are injected into the Circoclean reactor for maximum removal of the  acidic components (such as chloride and sulphur), heavy metals and dioxins.

The baghouse filters separate the solid components in the form of flue gas purification residues.

These residues are first solidified and then dumped into a Category 1 landfill.

The final step in the cleaning of the flue gases is the removal of the rest of the chloride and sulphur components by means of wet washing with sodium hydroxide.

Continuous monitoring of the emissions by an emissions laboratory located at the chimneys, guarantees that the purified flue gases that leave the chimneys comply with the strictest environmental standards.
