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.
