A petroleum alternative: investing in Bloom Biorenewables

This article was originally published in Allnews on 3 April, 2025, under the headline: “Major sustainable funds invest in Bloom Biorenewables”.

Bloom Biorenewables Ltd., based in Marly, Switzerland, announced the completion of a CHF 13 million series A funding round. This significant investment was led by Anaïs Ventures and Valquest Partners, with participation from several notable investors, including Breakthrough Energy Ventures, Lombard Odier Investment Managers, Capital Risque Fribourg, Btomorrow Ventures, Amcor Ventures, Rosebrook and The King Baudouin Foundation, on behalf of R&Co4Generations, the Rothschild & Co. philanthropic fund.

"We are incredibly grateful for the support from our investors and excited about the opportunities this funding brings," said Remy Buser and Florent Héroguel, Co-CEOs of Bloom Biorenewables. "With this investment, we are well-positioned to advance our technology and bring our sustainable solutions to market. Our AAF technology represents a significant leap forward in biomass upgrading, and we are eager to demonstrate its potential to transform the industry."

At the heart of Bloom Biorenewables' technology is their groundbreaking Aldehyde-Assisted Fractionation (AAF) process, developed at the Laboratory of Sustainable and Catalytic Processing (LPDC) at EPFL. This innovative technology efficiently separates the cellulose fraction while stabilising lignin polymers and hemicellulose-derived sugars. By stabilising these structures, Bloom Biorenewables can fully valorise lignin and hemicellulose for the first time. This breakthrough is set to disrupt the field of biomass upgrading, offering new pathways for converting plant material into high-value chemicals and materials.

The urgency of finding new technologies to leverage renewable carbon cannot be overstated. As the world grapples with the climate crisis, the need for sustainable and renewable solutions is more pressing than ever. Advanced technologies to use renewable carbon, such as those developed by Bloom Biorenewables, are essential in reducing emissions and transitioning to a more sustainable economy. By investing in innovative solutions like AAF, we can accelerate the deployment of cutting-edge technologies and make significant strides towards a carbon-neutral future.

Path to Commercialisation

The new funding will be used over the coming years to scale the AAF process and engineer the first-of-a-kind (FOAK) commercial-scale units, while accelerating market entry. This investment marks a pivotal step in the company's mission to revolutionise the materials industry and contribute to a more sustainable future.

“We have been impressed by the potential of Bloom’s chemistry”, says Julien Firmenich, CEO of Anaïs Ventures. “We are delighted to support the team in their ambitious endeavor to develop and commercialise breakthrough sustainable products.”

“This investment embodies our commitment to empowering visionary companies that are revolutionising the field of sustainable chemistry”, added Fadi Noureddine and Walid Sfeir, Founders and Managing Partners of Valquest Partners. “We are delighted to invest in Bloom, inspired by its pioneering work with Aldehyde-Assisted Fractionation (AAF) technology, and we do look forward to supporting its on-going innovation and leadership in biomass upgrading. This partnership aligns seamlessly with our forward-thinking vision to accelerate the development and scaling of transformative sustainable Greentech solutions”.
