Ever try to destroy a fiber glass boat?
Sure, you can burn them but you end up with a big pile of glass fiber crap. I don’t think it ever goes away. Furthermore, the resins are nothing but petroleum products that burn with a big pall of black smoke.
Oh boy, they really saved the environment didn’t they?
The real kicker is that they took more energy to produce than they generated during their “ useful “ lifespan.
In fact a company that has a process to recycle wind turbine blades plans to make extra money by recycling fiberglass boats and other crap that’s made in much higher volumes and has been landfilled for years.
