Have you ever wondered how green wind energy really is, especially when you see those vast piles of wind turbine blades dumped in landfills? Social media posts with photos of wind turbine blades in landfill have raised this question, casting doubts on the sustainability of wind power. Is it actually horrible for the environment?

Today, we'll examine why recycling wind turbine blades is such a challenge, focusing on the materials and manufacturing methods involved. Then, we'll scrutinize the current recycling methods and discuss what needs to change for blades to be effectively recycled. We'll also evaluate the efforts of wind turbine manufacturers and composite material suppliers towards this goal.

If you would like to help develop the Engineering with Rosie channel, you could consider joining the Patreon community, where there is a chat community (and Patreon-only Discord server) about topics covered in the videos and suggestions for future videos and production quality improvements.   / engineeringwithrosie
