CO₂ 100% from the Swiss atmosphere

Thanks to the ARA Bern, 100% of the CO₂ can be obtained from the Swiss atmosphere. At ARA Bern, the CO₂ required is actually waste derived from the production of biogas. Biogas is produced by the biodegradation of biomass, such as sewage sludge or organic residues, whereby CO₂ is removed to refine the gas. This is then liquefied and transported by Salzmann AG Transporte in biogas-powered trucks to our production facility in a climate-neutral manner, before being permanently stored in recycled concrete.
