New biomass-derived resin delivers 76% strength boost over plastic

Researchers at the University of Oulu in Finland have developed a new class of bio-based polyester and epoxy resins derived from forestry and agricultural waste, such as sawdust and straw. These biomass-derived resins mimic traditional fossil fuel-based materials but offer significant advantages, including up to a 76% increase in tensile strength compared to commercial fossil-based polyester resins. By utilizing lignocellulosic biomass components like cellulose, hemicellulose, and lignin, the team has created high-performance materials without compromising cost or industrial scalability. Beyond enhanced mechanical properties, these bio-based resins address a major challenge in the composite materials sector: recyclability. Unlike conventional composites, which are difficult to dismantle and often end up in landfills, the new resins can be chemically broken down and fully repurposed, enabling a circular economy model. The production process is compatible with existing manufacturing infrastructure, minimizing cost barriers and facilitating industrial adoption. With three patents filed, the researchers are seeking industrial partners to scale
