The linked article is misrepresented.

Two points regarding blade recycling techniques taken straight from the top of the article:

- Cement co-processing and chemical dissolution are primary viable methods, yielding $27.57/ton and $199.71/ton returns respectively.

- Chemical recycling achieves top circularity (PCI=0.7) and notable carbon reduction (−0.475 t CO₂/ton).

Chemical recycling is not yet ready for industrial use; cement co-processing is.

Concrete recycling is actually a pretty big deal. For most of building history here the standard material to put behind basement walls, retaining walls, and so on, for drainage was crushed scoria. Now it's crushed concrete. Some amount of effort but you're recycling existing stuff, and they recover the reinforcing steel as well.

Cement co-processing is not exactly recycling as the original material (fiberglass) can't be reused for its initial purpose.
