Last week, CelluXtreme contributed to two important forums for innovation and advanced materials: Ny Teknik’s 33-listan event in Stockholm and the 2025 MRS Fall Meeting & Exhibit in Boston, USA. Together, they highlighted how Sustainable Material Technology can support a future that is both secure and resource efficient.
Back at 33-listan – this time on the panel
In 2024, CelluXtreme was selected as one of Sweden’s 33 best technology start-ups by Ny Teknik – a milestone that marked our place in Sweden’s innovation landscape. This year’s 33-listan event brought us back to the stage in a new role. Our CEO, Anna Wiberg, joined a panel discussion on accelerating civil defense development and innovation.
“It is always inspiring to be at Ny Teknik’s 33-listan. Showcasing and celebrating technology is more important than ever as we work toward a future that is sustainable, resource-efficient and secure. Events like this gather brilliant minds and groundbreaking ideas – the combination we need to create solutions that truly matter.”
Sharing our latest fibre–epoxy interface research at MRS in Boston
In the same week, CelluXtreme’s CTO Daniel Söderberg and R&D Manager Karl Håkansson represented the company at the 2025 MRS Fall Meeting & Exhibit in Boston – one of the world’s leading gatherings for materials research. Karl presented our latest development on engineering strong interfaces, a key lever in composite design.
The way a fibre bonds to the surrounding matrix governs how efficiently loads are transferred, how robust a component is to moisture and fatigue, and ultimately how far we can push performance.
CelluXtreme’s nanocellulose-based fibre is designed from the ground up to enable strong bonding to epoxy resin, opening a pathway to structural composites that combine:
- high mechanical performance,
- bio-based and renewable raw materials, and
- recyclability and low-emission processing
Karl’s presentation builds on work by Sabrina Assenheimer. These efforts deepen our understanding of the fibre–matrix interface and help us design Green Leap composite materials that are functional and sustainable by design.
