Norrköping Wastewater Treatment Plant is owned by NODRA AB (formerly Norrköping Vatten och Avfall AB) and treats wastewater by removing debris, organic material, nitrogen, and phosphorus through mechanical, chemical, and biological processes. To utilize the surplus gas—previously a relatively untapped resource—NODRA chose to collaborate with Againity and invest in an ORC turbine.

Againity delivered a complete containerized solution including a gas boiler, hot water tank, and an automated ORC system with a gross electrical capacity of 49.9 kW. The facility is expected to produce approximately 85 MWh of electricity and 1,000 MWh of hot water annually. The hot water is used internally to heat the plant’s digesters. NODRA has signed a service agreement with Againity to ensure long lifetime and minimal maintenance.
