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
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.
