Contract: RWE Knapsacker Hugel

Approximately 180,000 t/a of dewatered and pre-dried municipal sewage sludge is to be incinerated per line.

The excess steam produced during incineration is fed into the local steam collector (17 bara, 350°C) at the processing site.

The phosphorus-containing ash can then be used for targeted phosphorus recovery.

The waste water-free, multi-stage flue gas cleaning system will be designed to meet the more stringent limits to be expected in the future.

Once the permit has been obtained and the investment approved, the lines are to be erected within 36 months.
