Mannstaedt, in collaboration with E.ON, pioneers an innovative heat reuse strategy to slash CO₂ emissions by over 1,800 metric tons annually. This waste heat recycling initiative via an advanced heat exchanger system marks a significant step towards sustainable energy management.


In an ambitious move towards sustainability, Mannstaedt unveils plans to harness waste heat from its production facilities, a project facilitated by E.ON. By redirecting this waste heat internally, Mannstaedt anticipates a remarkable 40% reduction in energy consumption for internal heating, correlating to an annual CO₂ emission reduction of over 1,800 metric tons.

This strategic shift towards a sustainable energy concept is part of Mannstaedt's broader initiative, aiming to save 1,800 metric tons of CO₂ emissions yearly. The significant environmental impact of this endeavor equates to the yearly emissions of approximately 450 to 500 gas-heated older single-family homes, as calculated by the Verbraucherzentrale Nordrhein-Westfalen.

The heart of this initiative lies in an innovative heat exchanger system developed by E.ON. Formerly expelled into the environment, waste gases from the production plant will now be channeled through this system to heat water, feeding the site's heating supply circuit.

This forward-thinking approach anticipates a substantial 30% reduction in the company's future thermal energy requirements. Collaborating with E.ON Energy Infrastructure Solutions Germany, Mannstaedt also aims to achieve additional thermal energy savings of up to ten percent through further optimizations at its production facilities.

Sebastian Ahrens, Commercial Director at Mannstaedt, and Alexander Fenzl, Chief Sales Officer at E.ON Energy Infrastructure Solutions Germany, express enthusiasm for the project's impact and the challenges and opportunities it presents.

E.ON's investment of around $3 million in the primary plant is supplemented by potential public funding of $900,000. Construction for this pioneering project is slated to commence next year, with meticulous planning to ensure continuity in ongoing production. The thermal unit's operationalization is scheduled for late 2024, aligning with GMH Gruppe's overarching goal of achieving climate-neutral production by 2039.


Mannstaedt's collaboration with E.ON represents a remarkable stride towards sustainable energy management, setting a precedent for eco-friendly industrial practices. This innovative waste heat recycling initiative underscores the company's commitment to environmental stewardship and aligns with broader industry goals of achieving carbon neutrality.
