Bloom Biorenewables raises CHF 13M for sustainable materials development

Bloom Biorenewables has secured CHF 13 million in Series A funding to advance its Aldehyde-Assisted Fractionation (AAF) technology, a process that allows for the full utilization of plant biomass for high-value chemicals and materials. The investment will support the scaling of Bloom's technology and the development of commercial-scale units.

Bloom Biorenewables, a Switzerland-based cleantech company, has raised CHF 13 Million in a Series A funding round to advance its Aldehyde-Assisted Fractionation (AAF) technology. The funding will support scaling the process and developing first-of-a-kind (FOAK) commercial-scale units to accelerate the shift toward renewable carbon sources.

The round was led by Anaïs Ventures and Valquest Partners, with participation from Breakthrough Energy Ventures, Lombard Odier, Capital Risque Fribourg, Btomorrow Ventures, Amcor Ventures, Rosebrook, and The King Baudouin Foundation on behalf of R&Co4Generations, the Rothschild & Co philanthropic fund.

Developed at EPFL's Laboratory of Sustainable and Catalytic Processing, AAF efficiently separates the cellulose fraction while stabilizing lignin polymers and hemicellulose-derived sugars. By preserving these structures, Bloom Biorenewables fully valorizes lignin and hemicellulose, opening new pathways for converting plant material into sustainable chemicals and materials.

As industries seek alternatives to fossil-based resources, technologies like AAF play an essential role in employing renewable carbon. With this investment, Bloom Biorenewables is positioned to scale its technology and accelerate market adoption.

Bloom was ranked among the TOP 100 Swiss Startups, won Venture Kick, and participated in the Venture Leaders program. "Venture Leaders program was an intense week with the perfect combination of investor pitching, networking, and social events," commented Co-Founder and co-CEO Florent Héroguel.
