Innovatherm Gesellschaft zur innovativen Nutzung von Brennstoffen mbH

Innovatherm Gesellschaft zur innovativen Nutzung von Brennstoffen mbH has operated the largest fluidized-bed furnace in Europe for municipal and industrial sewage sludges in Lünen since 1997. The company converts the energy content of wastes into steam to supply its thermal drying plant and into electrical energy, part of which is sold to third parties. The parent company BETREM ensures plant throughput; through BETREM Innovatherm receives sludges from the Emschergenossenschaft, the Lippeverband, other wastewater operators, waste management companies and firms from the pharmaceutical and chemical sectors. The thermal sewage sludge drying plant was commissioned in June 2024, increasing throughput initially from about 240,000 t/a to a maximum of 360,000 t/a (technically approved up to 480,000 t/a).
