At Biosorbe, we’re developing sustainable absorbent and fibre technologies designed to replace fossil-based materials across multiple industries.

We sat down with our CTO, Christoffer Olausen, to talk about the technology behind Biosorbe, the challenges of scaling innovation, and where he sees the biggest opportunities ahead.

Q: What led you to Biosorbe?

“I have a background in Chemical Engineering with a materials focus from Uppsala University. After starting my career at Ragn-Sells working with hazardous waste management, I was approached about joining Biosorbe as a Development Engineer.

What attracted me was the combination of engineering, materials development, and the opportunity to work in an early-stage company environment. Over time, I stepped into the CTO role, which has been an exciting journey.”

Q: What makes the Biosorbe technology different?

“Our technology is built around hydrophobized cellulose fibres with very high performance and strong scalability. In just a few years, we’ve gone from lab-scale production to industrial-scale manufacturing.

What makes Biosorbe unique is not just the hydrophobicity itself, but the level of performance we achieve and the additional material properties we can create, including formed and molded fibre applications.”

Q: What do people often misunderstand about the material?

“Many people either haven’t considered cellulose as a replacement for fossil-based absorbents, or they underestimate how well the Biosorbe material actually performs.

Hydrophobic cellulose isn’t new in itself, but the performance level we achieve is something very different compared to conventional alternatives.”

Q: What has been one of the biggest challenges?

“As a small company, prioritisation is critical. The technology has potential in so many different areas, so deciding where to focus our time and resources is always one of the biggest challenges.”

Q: What excites you most about the future?

“The most exciting part is the potential to replace fossil-based materials with more sustainable alternatives across multiple applications.

Absorbents remain a key focus for us, but we also see strong opportunities in filtration and formed fibre products moving forward.”
