Renewable CO2 Ecosystem
Fields of crops such as wheat or corn, absorb the CO₂.
Farmers harvest the crops.
The harvest is processed and releases CO₂.
The CO₂ is captured as a by-product from the fermentation.
The biogenic CO₂ is turned into fresh, tasteless gas for carbonation.
The CO₂ is released when the sparkling water is consumed.
