But what will do with the grindings? Not many want recycle Glass Fibers either.
I didn't watch it all in detail but they stated at some point, longer fibers are more valuable for recycling. Meaning concrete reinforcement or something like that. At least if you shred it down like that it will be easier to pack in a landfill. Oh well.

Didn't watch the video but the first thing I thought was fiber reinforcement in concrete. Poured out 1,000's of yards of the stuff.

Didn't read it all but how about a nice chain saw with a carbide chain teeth like fire folks use.
Would need to suit up like anyone that works on corvettes in a body shop would.
Have a sort of tent to follow along with and a spray mist of sorts.
And wow 30k plus pounds in blades on one of those things.

Just melt the fibers of the fiber glass.

All a huge waste of everything with those things. Just use nice old clean renewable mineral oil AKA petroleum.

Though less environmental, chop off the tip, stand it on end and fill the first few feet with cardboard and spark it up, might make a heck of a show. Need a lot of cardboard

I got as far as his statement about not being able to reuse the concrete footings and I had to shut it off because that's complete BS.
If they so desired they could stand another windmill up there and once they figure out how to just change the blades and generators they could keep going in that same site.
The concrete footing does not fatigue LOL.

Yes----It was just done here on a wind farm situated on the Wa/Ore state line last year.
The farm was erected in 1994, replaced some towers--generators and all blades. This
thread----I'm surrounded by wind farms, most of the talk is disinformation, just haven't
had all the issues--most is babble quacking.

Northern MO, most of IA wind farms experiencing Blade failures, bad design sets up stress cracking to final fail from the Inside out. The sites have been determined as the foundation piers are too small to accommodate larger currently available turbines as well were not spaced by distance enough to avoid turbulence issues that created the cracking where will be abandoned in place.

Will retain those turbines that do not display the stress cracking issues until fail. New farms will have to be erected to replace.

I have a sure way to dispose of windmill blades but it would require a substantial investment which frustrates me because I picked up approximately 100 ponds of cut up windmill blade material and tested my theory in my back yard and the result was three sellable products at the end of my experiment. I did the same thing with cut up tires and the result wS exactly the same 3 sellable materials. Wish I had the money to open a processing plant to recycle these horrible items that go to our landfills and hurt our environment. The most frustrating thing is I've proved that it works but how do you trust a company or individual with something as profitable as this would be? I DONT have money to patent ect. I just live with these ideas and they get shelved.

Multiply by a Factor of 10, not just the number, the Factor, annually. That is why is does not go into production. End up with thousands of tons of presumed salvable end result material, that no one truly needs

Well, if there are loans available for putting up windmills there should be loans available for recycling, just have to incorporate so that if it fails you're not on the hook

A Corp or LLC is no protection if one signs a Personal Guarantee on the loan with the bank.

I worked for a guy who did framing, really good framing company, started working with banks to build on vacant properties and his theory, 'never play with your own money'
