Old concrete will be recycled and crushed. CO2 is then permanently stored in the stones to be reused for mixing new cement.

The arabern processes the biomass supplied into high-quality biogas.

Food waste from restaurants and biogenic waste from industry and commerce that is no longer consumable must be disposed of. The biomass obtained in this way is fermented with the sewage sludge to produce biogas.

Neustark captures the CO₂ directly in the biogas plant and stores it as liquid gas to simplify its transportation.
