Harnessing waste heat to help the environment

Since 2015, our facility in Dausenau, Germany, has significantly reduced its environmental footprint by reusing waste heat— lowering both greenhouse gas emissions and water consumption.

Capturing waste heat to conserve natural resources

Spurred on by our ambitious sustainability targets for 2030, which include a 50% reduction in direct carbon emissions, our facility in Dausenau, Germany, is striving to reduce its environmental footprint and use fewer natural resources.

At Dausenau, we produce circuit breakers as well as command and control devices. The site makes significant use of hot injection molding—melting and pressing plastic into new forms. Heating and cooling the presses requires considerable electricity and water.

Since 2015, the site has deployed a number of innovative technologies to capture and reuse waste heat from the presses, significantly slashing the consumption of both natural gas and water.

Using fewer resources, emitting fewer GHGs

When the site implemented the ISO 50001 energy management standard in 2015, our Dausenau team researched new opportunities for sustainability and seized the chance to invest in innovative technologies that could save resources and benefit the environment.

New solutions were installed, such as heat exchangers or compressor systems with heat recovery capabilities. These technologies enabled excess heat from the site’s presses to be captured and reused to warm the facility during winter, greatly reducing the reliance on natural gas. As an additional benefit, reusing waste heat also lowered the volume of groundwater needed to cool the presses.

These efforts reflect our firm commitment to reduce greenhouse gas emissions and conserve natural resources wherever possible. Reducing onsite consumption of fossil fuels is a crucial step in the fight against climate change and a core part of global energy transition.

The impact of our new technologies at Dausenau is significant. In 2020, the facility used 46% less natural gas and 49% less water than in 2018. This success is now being taken further with the planned rollout of a closed cooling system, as well as a long-term effort to reduce overall electricity consumption. Similar technologies are also being deployed at other Eaton sites where there are opportunities to reuse waste heat.
