The project is the first of its kind in the world: Climeworks, a spinoff of the Swiss Federal Institute of Technology (ETH) based in Hinwil, in the canton of Zurich, uses a forward-looking technology to filter CO₂ directly out of the air, declaring war on climate change. What started as a startup idea has been used in beverage production since this spring. The CO₂ from Climeworks adds fizz to several products: VALSER Sparkling, VALSER Viva and VALSER Sparkling Lemon & Mint.
One reason for the French-language Radio Télévision Suisse (RTS) to set off for Vals: For its morning radio show, RTS visited the VALSER production plant in the Grisons mountains.
