[p2tech] Food Grade

Greg,
 
There are sources of CO2 related to brewing and ethanol production from
fermentation that would be renewable. 
 
"Renew also sells liquid carbon dioxide, a byproduct of ethanol
production. After it’s collected and cleaned of impurities, the company
sells it to the food industry as a refrigerant, carbonator for soft
drinks or dry ice. "

"An emerging trend in brewing is recapturing CO2 produced naturally
during the fermentation process and recycling it for use in packaging
operations. Some brewers use
CO2 Advance Purification Systems (CAPS), reducing emissions and
allowing companies to purchase
less CO2 for carbonation."

Does anyone know of a good source of food grade CO2 that is renewable?
