The Soehnergroup obtains thermal energy from a nearby biogas plant via a district heating network. This regenerative energy is mainly used at the Schwaigern site to generate cooling for the production process and air conditioning of the buildings via an absorption chiller.

The entire site is heated with renewable energy in winter. This saves around 6,000 tonnes of CO² per year.

In addition, renewable energy is produced via an existing photovoltaic system with 125 kWp.
