There's a difference between gas and gas

Our CO2 is exclusively produced from renewable resources in Europe. This means that the gas comes from sources that are already in the ecosystem. We’re not adding any unnecessary CO2 to the atmosphere.

This renewable CO2 should not be confused with CO2 extracted from underneath the Earth’s surface. 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.

8. The Renewable CO₂ Ecosystem starts over.
