Showcase project officially inaugurated: sustainable and innovative sewage sludge utilisation plant of sludge2energy GmbH in Halle-Lochau

On Thursday, 7 April, sludge2energy GmbH officially inaugurated the sewage sludge mono-incineration plant in Halle-Lochau (Saxony-Anhalt). In future, the plant will thermally utilise up to 33,000 tonnes of dewatered and 2,750 tonnes of dried sewage sludge per year. The total investment volume of the project amounts to about 30 million euros.

Delivery of sewage sludge for mono-incineration in Halle-Lochau

It is a showcase project with an impact that extends far beyond Saxony-Anhalt: sludge2energy GmbH, a subsidiary of HUBER SE and WTE Wassertechnik GmbH, officially inaugurated a plant for the mono-incineration of sewage sludge in Halle-Lochau. S2E Managing Director Harald Plank welcomed Rainer Köhler (Sales Director of HUBER SE), Saxony-Anhalt's Minister of Economics, Tourism, Agriculture and Forestry Sven Schulze and Dr. Ralf Schröder (Managing Director of WTE Wassertechnik GmbH) to the start of plant operation.

Minister Schulze and Thomas Roitzsch from the operating company WTE Betriebsgesellschaft mbH jointly pressed a buzzer and thus gave the symbolic starting signal for the operation of the plant.

S2E Managing Director Harald Plank: "Just starting the operation of a showcase project”

"Good things are worth the wait," said Harald Plank in his welcoming speech. "After 40,000 hours of engineering, 150,000 hours of assembly and commissioning since November 2020 alone, around 1500 plans drawn up and a total investment of around 30 million euros, we are finally starting the operation of a showcase project today." The mono-incineration of sewage sludge at the plant is based on the sludge2energy process in a stationary fluidised bed furnace. The planning, including construction, erection and commissioning of the plant was also carried out by S2E.

Rainer Köhler (Sales Director HUBER SE): "Thermal sewage sludge utilisation the right way"

"It is not only because of the unmanned operation that sludge2energy GmbH has succeeded with the sewage sludge incineration plant here in Halle-Lochau in a project that is unique in the world," emphasised Rainer Köhler (Sales Director HUBER SE) in his speech. "Thermal utilisation is the right way to go in the use of sewage sludge – and the energy-autonomous operation of the plant ensures sustainable energy management.”

Dr.-Ing. Ralf Schröder (Managing Director WTE Wassertechnik GmbH): "Convinced by the technology of this pilot project”

"The Halle-Lochau sewage sludge incineration plant is a pilot project and you are clearly a pioneer here," said Dr.-Ing. Ralf Schröder, member of the management board of WTE Wassertechnik GmbH. "WTE Wassertechnik GmbH is convinced of the technology and one must once again emphasise the commitment of every single employee." He added that the commitment of HUBER SE, who have always supported this special project, must also be particularly pointed out.

Afterwards, sludge2energy Managing Director Harald Plank gave a guided tour, explaining the process of thermal sewage sludge utilisation at the plant – from sludge reception in the sewage sludge bunker to thermal utilisation in the fluidised bed furnace, the S2E Fluidizer.

Halle-Lochau chosen as location in 2017

The plant for thermal sewage sludge utilisation is located in the Halle-Lochau recycling and resource management park at a site with good transport links between Halle (Saale) and Leipzig and will cover a total area of approximately 10,000 m2. The site is located on the grounds of the Halle-Lochau landfill in the Döllnitz district of the municipality of Schkopau. Due to its geographical proximity to the site, WTE Betriebsgesellschaft mbH (WTEB) from Hecklingen, a subsidiary of WTE Wassertechnik GmbH, will take over the technical management of the plant. The groundbreaking ceremony for the plant took place in 2019.

Recycling of around 33,000 tonnes of dewatered sewage sludge per year using state-of-the-art technology

In future, the sewage sludge mono-incineration plant will be operated around the clock – 24 hours a day, seven days a week. The incineration is designed in such a way that about 33,000 t of dewatered sewage sludge as well as 2,750 t of externally dried sludge can be utilised per year.

A decisive role in the operation of the plant plays its degree of automation: the operation of the thermal utilisation plant is planned as a 72-hour operation without permanent supervision (BosB mode). The comprehensive automation equipment ensures a high level of supply security for the entire plant. In addition, the plant can also be permanently monitored via secure remote access in accordance with the latest state of the art.
