As the basis of life, water is a valuable resource that deserves conservation. We use water in our manufacturing processes but aim to significantly reduce our consumption. Through our water and energy recovery systems put into operation in 2024 for cleaning the filters of our ultrafiltration systems, we saved more than 80,000 kWh of power and, by recirculating 75% of the approximately 50°C to 60°C rinse water, saved 5,500 m³ of water.

All our companies in Germany receive 100% of their electricity from renewable sources. This green electricity is purchased from a variety of suppliers. Around 60% comes from power purchase agreements that contractually specify the type of power plant, with hydroelectric power making up the dominant share.

At our headquarters in Traunreut, photovoltaic panels on the roofs of our production buildings generate 770 MWh of electricity. More panels are being planned. Meanwhile, two company-owned wind turbines are under construction near our headquarters. Set to provide power directly to our company, they are expected to meet one-third of our electricity needs starting in mid-2026. And as for heating, district heating covers half of our needs.

Beyond switching to renewable energy sources, we equally emphasize reducing energy consumption in the first place, not least for economic reasons.

To reduce greenhouse gas emissions, we continually succeed in optimizing our buildings and equipment. 

The cleaning agents we use besides water include various solvents, especially alcohols and acetone. We are working to determine the suitability of less environmentally harmful alternatives while taking into account the rigorous quality requirements of certain cleaning processes. 

The HEIDENHAIN headquarters has been Scope 2 carbon-neutral since 2021.

Thanks to our efforts in recent years, district heating meets most of the heating needs at our headquarters, causing Scope 1 emissions to play only a very minor role.
