Sign up for our convenient on-demand cylinder exchange service. It’s a smooth, circular set-up called The Cylinder Loop, to make sure you never run out of CO2. Convenient, simple, and smart.

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. CO₂ in the atmosphere

2. Natural crops

Fields of crops such as wheat or corn, absorb the CO₂.

3. Harvesting

Farmers harvest the crops.

4. Fermentation

The harvest is processed and releases CO₂.

5. Capturing CO₂

The CO₂ is captured as a by-product from the fermentation.

6. Renewable CO₂

The biogenic CO₂ is turned into fresh, tasteless gas for carbonation.

7. Drinking sparkling water

The CO₂ is released when the sparkling water is consumed.
