Yeah this smacks of "but wind turbine blades aren't recyclable"! So? It's still better than what we were doing before.
I didn't even know about that.
Wonder if they could crush them up and use them as concrete aggregate.
Nope, they put them in big graveyards
Need to figure out a reclamation process, but nobody's trying just yet.
They're genuinely just not that recyclable. And that's fine, they're still really helpful
Its not, but its less not-fine than fossil fuels.
The world doesn't have to go on forever, only 5 billion more years
Close. We sharpen them to use against the Kaiju.
"made mainly of carbon fiber, fiberglass, and balsa wood" from some random source. Doesn't sound like anything particularly toxic or difficult to source. I can't imagine putting them in landfill is a serious problem. So my response is "so what".
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.
