Unilin Technologies Secures European Patent for Groundbreaking Osiris Wood Recycling Technology

Unilin Technologies, the intellectual property division of Unilin, has been awarded European patent EP 4114629 for its pioneering Osiris recycling technology. This patent marks a significant milestone in the company’s mission to foster circular practices in the wood industry and reflects Unilin’s ongoing investment in sustainable innovation.

The patented Osiris system represents the first industrial-scale technology capable of recycling fiberboards—a long-standing challenge in the wood-based panel industry. Historically, the composite structure of fiberboards, which combines wood fibers with adhesives and resins, made them difficult to disassemble and therefore unfit for effective recycling. As a result, these boards typically ended up in landfills or were incinerated, contributing to environmental degradation.

With Osiris, Unilin has developed a scalable and practical solution to this issue. The technology enables the efficient separation of wood fibers from waste fiberboards, which can then be reintegrated with virgin wood to manufacture new fiberboards. This process not only reduces waste but also conserves natural resources by decreasing reliance on fresh wood material.

The Osiris technology is exclusively offered for licensing by Unilin Technologies in partnership with Dieffenbacher, a leading provider of wood-based panel production systems.

“We are proud to receive this patent, which underscores the innovation behind Osiris and the impact it can have on the sustainability of the fiberboard industry,” said a spokesperson from Unilin Technologies. “Our goal is to create real-world solutions that allow manufacturers to reduce their environmental footprint while maintaining high production standards.”

The granting of this European patent further strengthens Unilin’s intellectual property portfolio and opens the door for wider adoption of circular technologies across the board manufacturing sector. With global attention increasingly focused on sustainable production methods, Osiris offers a viable path forward for companies seeking to align with environmental targets without compromising efficiency or quality.
