Nesselnbach AG/Baden – In a new plant in Nesselnbach, Recycling Energie AG and Regionalwerke Baden liquefy CO2 that is produced as waste during the production of biogas. The liquid CO2 is sold in the food industry. This also reduces methane emissions.
Recycling Energie AG operates what it claims is Switzerland’s largest plant for the production of raw gas from food waste in Nesselnbach. This raw gas also contains CO2, which must be removed during further processing into biogas. So far, this CO2 has been released into the atmosphere. A new plant in Nesselnbach now diverts and liquefies it.
The operators of the CO2 liquefaction plant in Nesselnbach are satisfied with the first months of operation. “With the new plant, we can capture around 90 percent of the CO2 produced,” Philippe Lehmann, managing director of the operating company CO2 Energie AG, is quoted as saying in a statement. “That’s up to 3500 tons of CO2 annually.” At the same time, residual amounts of the greenhouse gas methane can be eliminated, which have also been released into the atmosphere up to now.
The liquefied CO2 is sold in the food industry. According to the operators, the plant is unique in Europe.
CO2 Energie AG, founded in 2021 and headquartered in Baden, is a joint subsidiary of Regionalwerke Baden and Recycling Energie AG. stk
