The only aspect the recyclers ever arrive at is Mix with Concrete, is fine until have to break it out or drill it then release the dust again, even worse to remove aged FBGLS reinforced concrete as full of hail and as dries out or degrades releases the hairs.

1)You might talk to the OEM (blade manufacturer) and ask them how they would part them into sections.
2)The engineering staff of the company that's tearing these units out may also have some ideas on destroying them.
3)Ship yards use some very high pressure water blasting equipment that should cut the glass.

I didn't take the job and I never found out what they did about moving them. I would like an opportunity to try different methods out and see what would work. I would not entertain doing it manually.

New recyclable wind turbine blade technology hopefully will be successful.

I wish the recyclers well but there is only so much need for concrete additive or as a filler in concrete and that is currently all this stuff is used for. The cement maker at Hannibal MO is incorporating Some of this stuff after it is ground up at a Louisiana MO facility as a fuel(Coal) stretcher and a kilned additive while the process runs for cement.
They have had EPA issued responses to Silica levels in air around the facility.

Primarily it is being burned.

I at first thought that picture had a guy with one of those mexican straw hats, sitting on a magnatrac mini dozer from the back of popular mechanics, and thought "he's going to be there forever".

Then I saw the tires off to the right and got a better sense of the scale and realized it was like a D10 or something. Great picture though.

We smash everything with the biggest, hardest boulder we can lift. pick it up with bucket & thumb, lift as high as you can, drop it on the blade.
I'd expect a lot of splintery debris to be produced, but not much dust.
I do electrical work where they build those blades. they don't take a lot of precautions about dust sanding them.

they are inert, so i don't see an ecological problem there. We doze under a lot nastier stuff in landfills.

It's the hypocrisy of promoting, nay.. requiring wind turbines for "Ecological protection"

My electric bill has a "renewable energy surcharge" every month. Means utility has to buy such energy at higher prices than they can generate electricity for. It's mandated by the state of NC.

Problems there as creates excess dust, Silica issues, similar to Asbestos where causes lung damage, Silicosis. Would have to be done continually wetted or EPA and OSHA have field day.

MOD EDIT - DM I banned the saw blade spammer so it leaves this post with no reference just so everyone else knows. CM
