Bloom Biorenewables raises CHF 13 million to scale renewable materials platform

Fribourg-based Bloom Biorenewables has raised CHF 13 million in a Series A funding round to advance its proprietary biomass upgrading technology and accelerate market entry.

Bloom Biorenewables, a cleantech start-up based in Marly (canton of Fribourg), has completed a CHF 13 million Series A funding round. The financing will support the scale-up and commercialization of the company’s proprietary Aldehyde-Assisted Fractionation (AAF) technology, designed to transform plant-based biomass into renewable materials for industrial use.

The round was led by Anaïs Ventures and Valquest Partners, with participation from a broad group of investors, including Breakthrough Energy Ventures, Lombard Odier Investment Managers, Capital Risque Fribourg, Btomorrow Ventures, Amcor Ventures, Rosebrook, and the King Baudouin Foundation via the R&Co4Generations fund.

Founded in 2019 and supported by EPFL research, Bloom Biorenewables is developing sustainable alternatives to fossil-based chemicals, targeting applications in packaging, coatings, textiles, and beyond. At the core of Bloom’s approach is its AAF technology, which enables the complete and stable separation of lignin, hemicellulose, and cellulose from plant matter. This allows for the full valorization of biomass components—an essential step toward circular, carbon-neutral material production.

“The support of our investors allows us to demonstrate the full potential of our technology and move toward large-scale deployment,” said Remy Buser and Florent Héroguel, co-founders and co-CEOs of Bloom Biorenewables. “Our ambition is to offer scalable, low-emission material solutions for the industries of tomorrow.”

The funds will be used to scale the AAF process and engineer Bloom’s first-of-a-kind (FOAK) commercial-scale unit, while accelerating the company’s market entry strategy.

This latest milestone builds on earlier recognition, including Bloom’s selection for Amcor’s Lift-Off Program, which supports disruptive start-ups in the packaging space. With strong institutional backing and growing industry interest, Bloom Biorenewables continues to position Western Switzerland as a hub for innovation in sustainable chemistry and cleantech.
