Mercer Rosenthal Gradually Resumes Discharge from Its On-Site Wastewater Treatment Plant

During the restart process following a four-week maintenance shutdown, the plant received a report on October 1, 2026, regarding discoloration in the vicinity of the wastewater discharge point. As a precautionary measure to rule out any adverse effects on the environment and water bodies, the company immediately halted the restart process and the wastewater discharge, retaining the wastewater in the plant’s own buffer basins. The Saale-Orla District Office subsequently issued a temporary swimming ban for the southern section of the Bleiloch Reservoir as a precaution.

Since the wastewater discharge was suspended on Thursday, the company has been in constant direct communication with the relevant authorities. On this basis, discharge from the plant’s own wastewater treatment facility into the Saale River was gradually resumed on October 3 in close coordination with the relevant environmental authorities. At the same time, preparations are underway to resume pulp production.
