CO2 Recovery Systems for Beverage Plants
A CO2 recovery system captures the carbon dioxide naturally produced during fermentation, cleans and stores it for packaging and carbonation — turning a purchased cost into an on-site asset.
Where the CO2 Comes From
Each gram of fermentable sugar yields roughly equal CO2 by weight. A 100 hL/week brewery vents enough gas to carbonate its entire output, plus more.
How a Recovery Skid Works
Fermentation CO2 is collected, scrubbed of organics, compressed, dried and liquefied into a buffer tank. Skids integrate with existing beer stone carbonation and filler bowl pressure.
Payback Considerations
Liquid CO2 purchases and delivery fees often justify a recovery skid within 18–36 months at regional scale, faster where bulk gas prices are high.
Safety and Purity
Built-in analyzers verify food-grade purity and O2 levels; redundant relief and room CO2 alarms are mandatory for confined spaces.
Frequently Asked Questions
Is recovered CO2 food grade?
Yes, after scrubbing and purification it meets beverage carbonation standards; continuous monitoring confirms purity.
What size plant justifies recovery?
Typically 80–100 hL/week and above, though bulk gas pricing can lower the threshold.
Does it integrate with canning lines?
It feeds the same carbonation and filler bowl supply your canning line already uses.
