Hey, Vogi - Did you mention CO2 recovery systems and tanks at the ethanol plant? How does that work?

I'm sure they're catching and compressing CO2 instead of releasing it into the atmosphere. It seems like ethanol production would make so much CO2 it would be a glut on the market. However it's used, it'll end up released in the atmosphere eventually.

Before ethanol, breweries were able to supply the demand for CO2. It's an inert gas, and I guess the uses are fire extinguishers, carbonating beer, maybe propellant in some aerosol cans? Are they finding a market for all that CO2?

Just wondered.
