Our sustainability measures

There are no fossil fuels required for our production processes. Our production runs with 100 percent green power, meaning electricity produced from renewable energy sources. At our main site in Kirchhundem/North Rhine-Westphalia we have been using 100 percent renewable electricity since 2018. At our other locations in Germany this has been the case since 2019 and at our sites in other European countries since 2023.

At the beginning of 2025 we also replaced the remaining oil heating system in our M1 administration building with a modern air-source heat pump powered by green electricity (please see the photo). As a result this building is now heated entirely with renewable energy.

Despite optimization measures, some of our buildings are still heated with fossil fuels such as natural gas or petroleum products. It is our goal to further reduce the use of fossil fuels every year. The CO₂ emissions we have caused are compensated by the retirement of CO₂ certificates.

We produce our new AMTRON® 4You wallbox family in all variants 100% climate-neutral. With various measures, we ensure that the CO₂ emissions during the production of the devices are kept as low as possible. For every gram of CO₂ that is still released, we invest in forest protection projects in Brazil and Peru. The calculation of the CO₂ balance of the wallboxes plus the associated charging cables is carried out in cooperation with "Fokus Zukunft" in a detailed and transparent manner, publicly accessible.

Through various measures we save energy in both our production and administration. For example at our buildings located in Kirchhundem-Welschen Ennest a special energy management system is in place: Since 2019 we have been using the waste heat generated in our plastics injection molding facility to heat our 14,000 m² production building M7 via a sophisticated system involving two underground water storage tanks, each with a capacity of 200 cubic meters. This is where we manufacture our industrial plug-in connectors. In 2023 alone this allowed us to save 94 percent of energy. Additionally the waste heat from the injection molding process is used to heat our neighboring administration buildings M10.1 and M10.2 via a local heating network. These buildings house our customer center and parts of our administration.

We are also continually replacing older machines with new, more energy-efficient machines in our contact part manufacturing facility and in our plastic injection molding production department.

Step by step we are replacing the lighting in our production facilities with LED light strips.

All lighting in our offices, hallways, bathrooms and kitchen facilities turn off automatically. Lamps are only lit whenever people are in the room. The lighting goes out shortly after leaving the room.

We are continually replacing the windows, doors and the roof insulation of our older buildings.

All energy-saving measures are monitored by experts through our MENNEKES energy management system, which is certified according to DIN EN ISO 50001.

In our production, which is certified according to ISO 14001 environmental management standards, we follow the so-called “mill concept”: materials such as leftover plastics from the manufacturing of our plug-in connectors and eMobility charging solutions are consistently reused. For this purpose two so-called granulator machines are in operation (please see the photo). Leftover brass shavings are melted down and reused in the production of our contact parts.

Many of our product solutions are already delivered in pure paper and cardboard packaging without color printing, plastic bags or Styrofoam – for example our AMTRON® wallboxes. Due to the product weight our AMEDIO® charging stations are shipped on pallets with PE foam supports. These are largely made from regranulates and are 100 percent recyclable.

A closed water cooling circuit is in place in our plastic injection molding production department. We are only withdrawing as much water as is necessary for cooling water for our machines. At our Kirchhundem-Welschen Ennest location we are collecting the water used for machine cooling and heated water in an underground water reservoir, where it is newly cooled by natural means and can be reused for machine cooling. This way no fresh water is needed.
