'recyclable' is such a vague term. E.g. radiation-affected typically easily recycled materials are very hard to deal with (think e.g. pipe steel from power plants) and are effectively non-recyclable, instead of close to 100% recyclable, as their non-contaminated counterparts.

Opposed to that, battery recycling is mostly hard to deal with in terms of economics, and admittedly the chemistry involved is complex, but at least from a technical point of view, plenty of solutions are available - and the tech is coming in relatively quickly now that the demand is there (remember, first generation EVs are just now getting closer to EOL).

It's slightly amusing that recycling of a wind turbine is treated as if it was a big deal - yes the laminated rotor parts can't be part of circular economies, but the total material amount of this laughably small. All the metal components are very easily recycled.

I'm talking about wind turbine wings. A lot of stuff is fiberglass and have to be buried.

In many Western nations bury them is now forbidden. Most are burnt in cement kilns (producing useful heat).

In France, 95% of the mass of a wind turbine must be recycled (legal obligation), the concrete base is not spared and the law requires wind farm operators to lock (upfront) a financial guarantee (deposit).

Recyclable blades are appearing (RecyclableBlade, ZEBRA, PECAN...) and even existing ones are being considered: https://www.offshorewind.biz/2023/02/08/newly-discovered-che...

According to EDF (multinational electric utility company owned by the government of France, the giant in France, owning and operating all nuke plants) 94% of a solar panel is recyclable. In France most of it is already recycled.

Yea, I know. Their volume may look impressive, the actual amount of material is quite small and 'burying' that absolutely non-toxic stuff isn't any problem.
