A media spotlight in the Swiss business press
On February 20, 2026, PME Magazine—a leading source for Swiss economic news—published an article on the partnership between WasteOlas and Brasserie Docteur Gab’s. Written by journalist Sophie Marenne, the article highlights a concrete innovation: the capture and reuse of CO₂ from beer fermentation, a local circular economy model now operational in Puidoux (VD).
A Swiss-made system, from pilot project to inauguration
The article traces the evolution of the partnership, which began in 2023 as a pilot project and is now fully operational. In mid-February 2026, the brewery officially inaugurated its new CO₂ recovery system, installed by WasteOlas at its facility in Lancy (GE).
Gabriel Hasler, co-founder of Docteur Gab’s, explains how the system works in the magazine: “Together with this partner, we have developed a Swiss-made system to capture CO₂ from the fermentation process, compress it, filter it, verify its purity, and reinject it into other internal processes.”
The numbers speak for themselves
PME Magazine puts the impact of the program into context with compelling data :
- 20,000 hectoliters (or 2 million liters): that is Docteur Gab’s annual production, accounting for less than 1% of beer consumption in Switzerland.
- The system reduces the need to purchase industrial CO₂ for beer stabilization and carbonation.
- Gabriel Hasler’s stated goal is clear: “to eventually meet 100% of our CO₂ needs while optimizing energy consumption and quality at every stage.”
Institutional support that lends credibility to the initiative
The article highlights an important point: the project was partially funded by the Office for Economic and Innovation Promotion (SPEI) of the Canton of Vaud. This public support validates the economic and environmental merits of the technology developed by WasteOlas and bolsters the credibility of the approach within the Swiss entrepreneurial ecosystem.
Dr. Gab’s, a committed partner across all fronts of circularity
PME Magazine expands on this by noting that, in mid-January 2026, the brewery also joined the board of the new Swiss REuse association, alongside glass bottle and keg manufacturers such as Vetrum, Vetropack, and Kegsman. The goal: to make the cleaning and reuse of glass bottles the norm in Switzerland. One figure stands out: according to the Swiss Brewers Association (ASB), only 33% of the beer consumed in Switzerland was delivered in reusable packaging in 2024.
Docteur Gab’s multi-pronged approach—using recycled CO₂ through WasteOlas and reusing bottles via Swiss REuse—illustrates the brewing industry’s broader shift toward more sustainable practices.
WasteOlas: Validation by the Market and the Business Media
This feature in PME Magazine represents a significant recognition for WasteOlas. Being highlighted in a publication read by Swiss economic decision-makers confirms that the CO₂ capture and recovery technology developed by WasteOlas addresses a real market need—at the intersection of environmental imperatives and the economic competitiveness of SMEs. The support of the Canton of Vaud, Docteur Gab’s ambition to achieve complete CO₂ self-sufficiency, and the brewing sector’s growing interest in circular solutions are creating fertile ground for the larger-scale deployment of this Swiss-made technology.
