A scientific innovation could revolutionize the way we recycle wind turbinesallowing them to be transformed into products such as gummy candies. The researchers of Michigan State University have developed a composite resin composed of glass fibers combined with a vegetable polymer and a synthetic one. This material, at the end of the shovels’ life cycle, can be broken down and reused to make new products, including other shovels and gummy sweets.
THE’wind energy represents one of the main renewable sources in the world. However, wind turbines, often as long as half a football field, are made of fibreglass, a material that is difficult to dispose of. Most end up in landfills, creating a growing environmental problem.
To overcome this criticality, the team of researchers designed an innovative type of resin. Through treatment with an alkaline solution, this resin turns into potassium lactate, an edible substance also used to create gummies and sports drinks.
From the wind farm to the infinite recycling cycle
John Dorganone of the study’s authors, said he personally tasted candies made from potassium lactate, demonstrating that the material is safe for food use. But the applications don’t stop there: the same process also allows you to recover PMMA, an acrylic material widely used in products such as car windows and headlights. Dorgan highlights the importance of the process in the global carbon cycle:
A carbon atom from a plant, such as corn or grass, is identical to one derived from fossil fuels. With our system, we can go from durable materials to food products and back again, closing the loop in an infinite circular economy. The idea of being able to completely dissolve and reuse wind turbine blade material represents significant progress towards sustainability. Our resin system allows you to recover and reuse everything, ensuring continuous and endless recycling.
This approach could radically change waste management in the renewable energy sector, opening new perspectives for a more sustainable future.
