CdTe panels (popular in US for mainly political reasons -- consider importing Si panels from Tblisi instead!) are likewise very recyclable: the 8 g/m^2 of cadmium are bonded to glass and overlaid with tellurium, both valuable and much more easily separated industrially than from native ore.

There would of course be no public interest in "holding" used-up wind turbine blades because they are not a public health hazard. If you were obliged to hold them anyhow, it would be super-cheap for that same reason, so would not add any to the cost of turbines.

By contrast, in addition to the expense of handling nuke waste, we are all subsidizing every nuke via indemnifying it against every conceivable disaster. We are obliged to do this because buying disaster insurance would push the price of nuke operations far, far outside even traditional marketable-cost envelopes.

Meanwhile, renewables + storage now cut way, way under traditional costs, such that nothing else is even conceivably competitive anymore, most places. In places where solar and wind are not locally practical, it is becoming similarly impossible to compete, in predictable near-future scenarios, with importing synthetic fuel from more favorable sites e.g. in the tropics.

(There are of course exceptions, such as where geothermal is already in place, but even there expanding geo is a hard sell. Steam turbines always require expensive periodic maintenance.)

To my knowledge the major problem with CdTe panels has been the extremely limited availability of Te, which is probably the main reason why they're under 5% of the market today. If one expects solar power to grow even more in the future, that market share will almost certainly shrink further still. So disposing of CdTe panels is a self-solving problem in the sense that we can't manufacture societally useful amounts of them anyway.

Ja, I doubt anybody uses them outside US.

We are assured a house fire cannot make your neighborhood a superfund site. I hope they are right.
