Viable Method for Bio-Derived Wind Blades Overview of Research Scientists at U.S. DOE's NREL envision a viable method for producing bio-derived wind blades that are chemically recyclable, allowing for the reuse of their components and eliminating the disposal of old blades in landfills. Performance of New Bio-Based Resin The research published in Science , demonstrates that the new bio-based resin performs as well as the industry-standard thermoset resin and exceeds the performance of some recyclable thermo plastic resins. Develo pment and Validation Researchers develo ped a 9-meter prototy pe blade to validate the manufacturability of PECAN, a biomass-derived resin created by NREL, PECAN, short for PolyEster Covalently Ada ptable Network, aligns with existing production methods. Advancements in Recycling Technology Current Recycling Practices Current technology allows wind blades to last around 20 years, after which they can be mechanically recycled, often shredded ...
