Umweltdienste Kedenburg GmbH is a private waste management company based in Hildesheim, Lower Saxony, and part of the Bettels Group owned by Knut Bettels. It operates the Heizkraftwerk Mansfelder Land in Helbra, Saxony-Anhalt, a combined heat and power plant fired with waste wood and, since October 2022, refuse-derived fuel, which supplies district heat to a residential and commercial area of Helbra.
The company also runs two mineral-waste landfills, a plastics sorting plant in Beckum and a mineral treatment site at Schlewecke. A concept for a second unit at Helbra, “Helbra 2”, was drawn up in 2024 and is scheduled for financing and planning in 2026–2027 under the municipal heat plan.
Key Takeaways
- Private GmbH with roots going back to 1982, re-registered as a GmbH in Hildesheim in 2011 after a change of legal form from Umweltdienste Kedenburg GmbH & Co. KG (Sarstedt); managing director since February 2019 is Knut Bettels.
- Owned by the Bettels Group, a family-run Hildesheim conglomerate (civil engineering, concrete, raw materials, logistics, energy, waste) whose sole shareholder is Knut Bettels; sister companies include Umweltschutz Mitte, Umweltdienste West, SAV, DIBA Entsorgung and Recycling-Park Harz.
- One thermal plant: the Heizkraftwerk Mansfelder Land in Helbra, commissioned in February 2003 as a waste-wood CHP plant with 27.5 MWth firing capacity, 5.8 MWel and 2.5 MWth heat extraction; the plant has been permitted for refuse-derived fuel since October 2022 and feeds the Helbra district heating network.
- Service area and other sites: landfills at Betheln (Gronau) and Drütte (Salzgitter), a 65,000 t/a plastics sorting plant in Beckum (North Rhine-Westphalia) and a mineral treatment site at Schlewecke (Bockenem); the plant in Helbra accepts waste wood (A II to A IV), RDF and biomass from the surrounding region.
- Project “Helbra 2” and heat-network transformation: a second unit fired with biomass, waste wood and RDF (up to 21 MWel or up to 78 MWth) was conceived in 2024; the municipal heat plan of the Verbandsgemeinde Mansfelder Grund-Helbra (June/July 2025) schedules financing and planning for 2026–2027 and targets a 90% supply of the Helbra heat network from the plant from 2030; the Bettels Group expanded further in the Harz region with acquisitions effective 1 January 2026.
