The unrenewable part of renewable
That's a problem that hadn't occurred to me. Still, it's less problematical than nuclear waste.

"Not only do they actually use renewable energy, but they are also more photogenic than, say, solar panels or a geothermal plant."
Tell that to the politically correct Kennedy family, friends and neighbors who've been fighting Cape Wind for over a decade. Pretty sure they'd disagree.

What's the big deal in recycling them?
If these materials are so tough, why not simply cut the blades into short lengths, then grind them to typical aggregate sizes for use in asphalt or concrete paving?
Certainly this is no more effort than mining gravel, transporting, crushing & grading it for the same purpose, and certainly less harmful to the environment.

There isn't a big deal.
Always follow the money:
"...the National Science Foundation (NSF) is giving $1.9 million to the University of Massachusettss mechanical engineer Christopher Niezrecki and the University of Wichita to find, as Fast Company puts it, biological-derived materials for biodegradable blade materials that replace carbon-fiber composites and petroleum-based epoxies, the current industry standard.
There's a fortune to be made in the crisis industrial complex.

You can't just dump any old thing into concrete or asphalt and expect it to hold. Some aggregates will make a mix weaker. Remember when various DOTs tried adding ground-up tires to paving mixes? The roads ended up falling apart faster, and in some cases, catching fire. You also have the issue of cost-effectiveness. Transporting a giant blade to a rendering facility and grinding it costs money. I'm sure someone has looked into this already.

Biodegradable?
Why won't the biodegradable blades decompose while in service?
