Why not?

Carbon fiber and fiberglass in concrete foundations would limit microplastics and add strength to the product. Throwing a never-decomposing product into a landfill is just taking up space for something that can decompose over a couple of hundred years. Reuse it at least once it there's a viable solution.

Sure. I mean, you could. Probably there are better sources, like construction waste, that you'd want to exhaust first, but I obviously haven't done a serious cost-benefit analysis, nor am I really qualified. My intuition is that you could do it but there are better uses of the time and money.

Relatively inert stuff in a landfill doesn't seem like the highest-priority use of the time and money. The resources used to scrap and recycle a wind turbine blade could probably be much better used for more consequential purposes.

I don't like the idea of crushed fiberglass in landfills, but it's far down the list of awful things we do to the planet. I think you're correct in assuming the effort is better spent elsewhere.
