FAQ

Our answers to your questions

  • What are the process steps for generating energy from waste materials?

    • Pre treatment (sorting, crushing, and pulping, if the raw materials contain oil, they can also be heated for oil extraction.)

    • Fermentation (synthesis of biogas)

    • Generation of electricity and heat by combustion of biogas in the combined heat and power plant

    • Processing of biogas into biomethane and possibly further into bio-CNG, bio-LNG, CO2

    • Feeding of biomethane into the natural gas grid

    • Fermentation residues are often used as a fertiliser

  • Which waste materials are suitable for generating energy?

      Not only slurry and manure end up in a biogas plant, but also existing residues from the food industry are suitable for generating energy. This may include brewery residues such as draff and surplus yeast, food leftovers from restaurants and commercial kitchens, confectionery, bakery residues, vegetable residues, pomace, fats and much more.

  • Can packaged food waste also be recycled?

      Only unpacked material can be used in the biogas plant!

      With our innovative technologies, we separate the organic material from the packaging. The organic material obtained in this way can be used to generate energy. Customised concepts are developed for this purpose in individual cases.

  • Why choose anaerobic digestion to treat POME wastewater?

      Anaerobic digestion can efficiently degrade organic pollutants in wastewater, and the biogas generated during the process can be used as a renewable energy source (such as power generation, heating, etc.). In addition, anaerobic digestion can also reduce greenhouse gas emissions and achieve environmental protection goals.
