An idea, a passion, a vision
My name is Michael Peytrignet, an engineer passionate about innovation and the environmental transition.
WasteOlas is, above all, a project close to my heart, one I conceived back in 2017 upon completing my studies at the Fribourg School of Engineering and Architecture (HEIA-FR).
Faced with the issue of CO₂, one question has been on my mind :
How can we turn this unlimited resource into an opportunity ?
Training for Entrepreneurship
To turn this vision into a project, I took the following Innosuisse training courses:
These programs were instrumental in helping me learn the basics of entrepreneurship.
From Idea to Business
In 2022, WasteOlas won the IDDEA Award, a major accolade that marked a turning point: we formalized the team and founded WasteOlas Sàrl, driven by our ambition to offer innovative and accessible solutions for CO₂ utilization.
Innovating with committed partners
From 2023 to 2026, WasteOlas is conducting a pilot project with Docteur Gab’s Brewery and Alcane Conseil as part of a sustainable collaborative initiative supported by a grant from the SPEI (Canton of Vaud).
We are developing a custom system for capturing and utilizing CO₂ at the brewery. At the time, no existing system was suited to the brewery’s size, so we had to innovate while staying within the defined budget.
The project has been a success: it has validated our approach and paved the way for the development of an open-innovation solution that is both technically and financially accessible.
Understanding the Brewing Industry
To support the development of the solution, WasteOlas conducted a market study on Swiss breweries in collaboration with the Swiss Brewers Association (ASB).
This collaboration has led to a better understanding of the industry’s needs, helped identify opportunities, and strengthened the network among key players in the brewing sector.
Star’Terre: Accelerating with Confidence
Starting in March 2024, WasteOlas has been participating in the Star’Terre support program. This tailored support has been essential for smoothly moving forward with the pilot project with the brewery, while developing and strengthening the business model.
Thanks to Star’Terre, I was able to structure WasteOlas’s growth, refine our strategy, and amplify the project’s impact.
Expertise in industrial decarbonization
In 2025, I earned the CAS in Sustainable Energy: Industry Decarbonization, a program organized by EPFL (IPESE) and HES-SO Valais-Wallis.
This program has given me a systemic and cross-sectoral understanding of energy efficiency and the decarbonization of industrial processes.
Through this CAS program, I have strengthened my ability to identify and analyze heat and mass flows in industrial processes, design heat recovery solutions, integrate innovative technologies, and propose comprehensive decarbonization strategies to establish industrial symbiosis.
Today, I am putting this expertise to work for businesses to help them accelerate their transition to carbon neutrality, with practical, effective solutions tailored to their specific needs.
A project that evolves, a vision that remains
A next-generation digital platform
WasteOlas is developing an innovative platform, initially designed for breweries but built to adapt to any small and medium-sized business or industry looking to monitor and optimize their energy and environmental performance.
Our goal: to make your data clear, accessible, and shareable, so that all your partners can speak the same language whether it’s for your carbon footprint assessments, energy audits, or environmental studies.
Your data belongs to you and remains under your control, ready to be easily shared with your stakeholders.
Free tools and feasibility study
As soon as you create your user account, you’ll have access to free tools to conduct an initial feasibility study: Can your brewery incorporate a CO₂ recycling system within its budgetary and operational constraints?
An add-on module is currently being developed to help you conduct a simplified carbon assessment.
Monitoring and reporting
The platform allows you to continuously monitor and analyze your data streams. This monitoring provides a solid foundation for all your future implementation studies, enabling you to design a system that is perfectly tailored to your operations.
Planning and Roadmap
With our simplified carbon footprint assessment, WasteOlas’s expertise, and our network of local partners, we help you develop a clear and realistic roadmap: investments, decarbonization milestones, and a customized action plan.
Mise en place de la capture et utilisation du CO₂ (CCU)
Nous vous accompagnons dans l’intégration d’un système CCU dans votre brasserie, avec un suivi précis de l’intégration dans vos procédés pour garantir une solution harmonisée à votre activité.
Continuous optimization and new opportunities
Congratulations you’re already putting your fermentation CO₂ to good use!
What’s next? Heating, electricity, energy, logistics… Together, let’s identify the processes that need to be optimized quickly to maximize positive impact, and then take it a step further—always with the support of expert partners in each field.
