On 17 July 2025, the waste to energy plant in Hannover-Lahe marks its twentieth anniversary. Since 2005, EEW has provided the region with secure and environmentally sound waste treatment, while supplying households with electricity and climate-friendly heat, EEW announced. This achievement is based on a close partnership with the municipal waste management association Aha and the energy provider Enercity.
Key Takeaways
- The waste-to-energy plant in Hannover-Lahe celebrates its 20th anniversary on 17 July 2025, having provided secure waste treatment and climate-friendly energy since 2005.
- Each year, the plant processes around 290,000 tonnes of waste, primarily from the Hannover region, reducing traffic and emissions.
- Planned expansions could see the facility meet up to a quarter of Hannover’s district heating demand, increasing usable heat output from 50 to 85 megawatts.
- The plant has treated approximately five million tonnes of municipal waste, contributing to regional energy security and environmental responsibility.
- Technical optimisations are expected to triple energy efficiency to up to 80 percent.
Each year, the facility processes approximately 290,000 tonnes of waste, the majority of which originates from the Hannover region. The short transport distances reduce road traffic and emissions. In close coordination with the association Aha, residual waste is reliably treated through thermal processes.
The energy generated is fed into the district heating and electricity grids. With the planned expansion of heat extraction in cooperation with enercity, up to one quarter of Hannover’s district heating demand could be met by the EEW facility in the future. To achieve this, usable heat output is set to increase from 50 to 85 megawatts. A long-term supply contract extending to 2055 underpins this sustainable collaboration.
Strengthening Regional Circularity and Energy Security
Guido Lücker, Technical Managing Director of EEW Energy from Waste Hannover GmbH, states: “We are proud to have contributed to secure waste disposal and climate-friendly energy supply in Hannover for 20 years. The close cooperation with aha and enercity demonstrates how regional responsibility, modern technology and supply security can work together.”
Since commissioning, the plant in Germany has treated and energetically recovered around five million tonnes of municipal waste in an environmentally responsible manner. Ongoing technical optimisation, including improvements to the steam turbine, heat recovery and control systems, is expected to more than triple energy efficiency to up to 80 percent.
