Messer recently announced that it has successfully completed the construction of its third CO2 production facility in Ölbő, Hungary. Highpurity carbon dioxide is extracted from a local natural source. The source itself lies at a depth of around 2,000 meters.

The gas is supplied primarily to the beverage industry in Hungary and in neighbouring countries. To satisfy their rapidly growing demand, original output at the site has now been tripled.

Besides extraction from natural sources, CO2 is often obtained as a by-product of processes in the chemical industry, after which it is purified. Natural CO2 has a high level of purity in comparison and can be obtained independently of other industrial processes.
