sludge2energy GmbH (S2E), a joint venture between WTE and Huber, is building a sewage sludge incineration plant on the site of the landfill Lochau (Saalekreis). In mid-September, the ground-breaking ceremony took place in the presence of Saxony-Anhalt’s Minister of Development and Transport Thomas Webel, Dr. Ralf Schröder and Manfred Graf.

The client and owner S2E is investing around 18 million euros. The earthworks for the plant have already begun and the first contracts have been awarded; regional companies in particular have the opportunity to participate. The plant will go into operation at the end of 2020.

30,000 to 35,000 tonnes of dewatered waste water sludge

The amendment of the Waste Water Sludge and Fertilizer Ordinance 2017 with the accompanying tightening of the limit values in Germany for nitrogen and heavy metals has meant that many sewage sludge producers can no longer use their waste water sludge for agricultural purposes. As a result, the need for thermal utilization of waste water sludge is increasing. Hence the investment in the new sewage sludge incineration plant Halle-Lochau. In the future, 30,000 to 35,000 tons of dewatered waste water sludge will be incinerated there and the phosphorous-containing ash will be deposited.
