A team of researchers at Washington State University has developed a cleaner and simpler way to recycle wind turbine blades.
The new recycling method breaks down the glass fiber-reinforced polymer (GFRP) material of the blades using superheated water and a mild chemical called zinc acetate.
The process successfully recovers both the glass fibers and the resin material, which are then added to other plastics, making them more than three times stronger and over eight times stiffer.
The recycling method is cost-effective, environmentally friendly, and offers a solution to the growing waste problem of retired wind turbine blades.
