Bio-CO2 production

An advantage of our CO2 liquefaction technology, is the liquid bio-CO2 production of consistent food grade quality while simultaneously creating additional revenue. Additionally, CO2 recovery and liquefaction technology contributes to reducing carbon emissions. This technology is an essential add-on for biogas upgraders and carbon capture systems. As it enhances the methane recovery of the biogas upgrading plant and the applications of the captured gaseous CO2.

CO2 purification

The CO2 liquefaction technology is unique by using CO2 a natural refrigerant, instead of Freon or Ammonia making it sustainable and environmentally safer. Our CO2 liquefier system has a containerized design for plug-and-play installation on-site with a quick start-up.  Purification and liquefaction of the CO2 enables sustainability, by serving as a responsible substitute for CO2 obtained from natural gas. Additionally, liquid (bio)CO2 has numerous applications in many industries, such as the horticulture-, food- and refrigeration industry.
