The advantages are obvious: biogas reduces CO₂ emissions, utilises waste sensibly and contributes to the energy transition.
One company that successfully utilises this technology is Zellinger GmbH from Walding in Upper Austria. Zellinger has been active in waste management for several generations and has become a pioneer in the utilisation of biogenic waste. The company's own biogas plant, one of the first to be certified to ISO 14001 in Austria, processes thousands of tonnes of organic waste every year - including food waste and biowaste from waste collection.
Proof that the circular economy works!
The special thing about Zellinger's biogas plant is its holistic approach: not only is environmentally friendly electricity and heat generated from biogenic waste, but this energy is also utilised in a targeted manner. A significant proportion supplies the company's own site in Gerling, making it largely energy self-sufficient. The surplus energy is fed into the public power grid so that others can also benefit from it.
With the expansion of the company's own ÖKO-Park in 2019, the efficiency of waste utilisation was further increased. The newly constructed processing plant enables even more sustainable utilisation of biowaste from municipal household collections. As a result, Zellinger is actively contributing to the reduction of household waste and the promotion of renewable energies.
Forward-looking mobility: electric lorries with their own electricity
Zellinger is thinking one step further: in addition to sustainable energy generation, the company is now also investing in a climate-friendly transport solution. Electric lorries are currently in the pipeline. These will be charged directly with the self-produced electricity from the biogas plant. This will create a closed cycle - from waste collection and energy generation to emission-free logistics.
