Mandi, a researcher at the Indian Institute of Technology, uses microwaves to recycle polymer composites to make wind turbine blades. They say this method is fast and sustainable compared to currently used methods such as landfilling and heat recovery. India is the fourth largest installed country of wind energy systems, with a total installed wind capacity of 40.893 GW as of July 2022. A team of researchers at IIT Mandi, India, has developed a fast and environmentally friendly method to recycle fibers from composite materials used to make wind turbine blades. No harsh chemicals are used in the extraction process, but green chemistry methods are used. Compared to virgin fibers, recycled glass fibers retain nearly 99% of their strength and more than 90% of other mechanical properties.
