How to recycle a wind turbine in a test tube

Wind turbine blades are huge, strong and hard to recycle. As the world's use of wind energy grows, researchers are searching for better ways to make use of old, decommissioned wind turbine blades. Now researchers in Denmark are using chemistry to find ways to break down the tough epoxy plastic that make up the blades, and recover useful materials for producing future wind turbines.

Can we maybe repair them and reuse them to make more energy thereby reducing the number of new blades needed?

In my Opinion, just shredding them, running it through an “Entrained Flow Gasifier” then remelt the slag into new fiberglass/rokwool would be more efficient/less complex.

Granted I’ll need to watch the video later + read the paper

"Days" of heat? And where will all that heat come from? (Let me guess - natural gas.) And at what cost?

energy intensive not a problem if the reaction occurs in an industrial sized thermos.

But funding this and building this non-recyclable blades surely feel good.

I don't know why people will just decide to waste their time reading my comment when clearly I have nothing to say.
And this person is still reading it

Why exactly would it be a good idea to be shredding old wind turbines to put in concrete (where it will inevitably become microplastics that get dispersed into the environment) and be used for CHILDREN'S PLAYGROUNDS if it intrinsically contains vast amounts of bisphenol-A?? And more importantly, why am I, and not the science journal reporting on these things addressing such an obvious glaring problem?

[barleyarrish]

Not just glass fiber (the dust is extremely toxic) but carbon fibre. They are not recycyleable, and still to this day have no Recycle Process
that can be demonstrated with energy requirement figures and product to blade weights given. so far all we hear is talk.

Unfortunately, "green energies" aren't green yet!

exactly WHAT CHEMICAL... pointless report. also could you narrate any slower possibly? watch on 1.75 speed. or better yet don't watch at all, for best experience

[ropro]

Lol, ironic that they didn't consider the full lifecycle of wind turbines when they were invented.
