There's a difference between gas and gas

Aarke's renewable CO2 should not be confused with CO2 extracted from underneath the Earth’s surface. Something that’s been isolated from our atmosphere for millions of years. Instead, our CO2 is a byproduct from agricultural production. It is then purified and certified to become a food-grade gas for sparkling water makers.

Renewable CO2 Ecosystem

1. COâ‚‚ in the atmosphere

2. Natural crops

Fields of crops such as wheat or corn, absorb the COâ‚‚.

3. Harvesting

Farmers harvest the crops.

4. Fermentation

The harvest is processed and releases COâ‚‚.

5. Capturing COâ‚‚

The COâ‚‚ is captured as a by-product from the fermentation.

6. Renewable COâ‚‚

The biogenic COâ‚‚ is turned into fresh, tasteless gas for carbonation.

7. Drinking sparkling water

The COâ‚‚ is released when the sparkling water is consumed.

8. The Renewable COâ‚‚ Ecosystem starts over
