Disposal of washed filter ash from flue gas cleaning for landfilling

On May 3, 2025, ERZ issued a public tender on simap.ch for the "disposal of washed filter ash from flue gas cleaning for landfilling" for the period from November 1, 2025, to December 31, 2029, within the scope of a state treaty. On November 3, one bidder filed an appeal with the Administrative Court of the Canton of Zurich against the contract award. By presidential order of November 28, 2025, the Administrative Court of the Canton of Zurich granted suspensive effect and authorized ERZ to provisionally award contracts to the other bidders or other companies for the services to be provided up to February 28, 2026, as specified in the tender. Under these circumstances, since the GEFA (washed filter ash from flue gas cleaning) is generated continuously and must be disposed of, the services must be awarded without competitive bidding until February 28, 2026, based on the decision of the Administrative Court of the Canton of Zurich. At the same time, the head of the Civil Engineering and

Waste Management Department is authorized to award the services without competitive bidding to ensure uninterrupted operation, should the administrative court proceedings continue beyond February 28, 2026, and the administrative court grant a further extension of the provisional contract award.
