True, that's what they propose in the article, but it's not like you get pure wood powder back, it's a wood-epoxy powder mixture. To which you then add epoxy to make new stuff... at some point you just have a mass of epoxy with traces of wood. That's downcycling at best.

Not sure how serious/scientific the author of the article is, as they also propose using the powder as mulch, which sounds like an ecological nightmare when considering that it's mixed with epoxy. But that might not have been the idea of the engineers who designed the wooden blades.

I'm not saying this technology is bad, even if the wooden blades get burned in the end at least they are not left as landfill like the ones right now.
