Energy efficiency

We are constantly improving our energy efficiency

We make targeted investments in energy-efficient building services and production facilities, and optimise existing processes. In doing so, we implement both large-scale and small-scale measures to reduce our energy consumption.

As part of the voluntary programme run by the Energy Agency for Industry (EnAW), we achieved energy savings of over 220 MWh in 2024 through optimisations to compressed air, refrigeration and ventilation systems.

We are also constantly improving our energy efficiency through smaller measures: in 2025, we reduced the number of printers and replaced the remaining devices with more energy-efficient models. This saves us around 1,430 kWh of electricity annually.

Further examples from previous years:

2022 – Ventilation optimised: Replacing two ventilation units saves over 120,000 kWh of energy annually.

2021 – Oil-fired heating system decommissioned: By dismantling the oil-fired heating system, we have further expanded the use of existing waste heat.

Optimised lighting: In 2018, we switched the lighting in our HUG Ringli shop at the Willisau production site to efficient LED technology. In 2020, the lighting in the production building in Malters was partially upgraded.
