True - however if you consider the true lifecycle from start to end (including construction costs, and decomissioning) nuclear is one of the most expensive power sources.

The costs for proper decomissioning of a nuclear plant and safe storage of the used materials are excluded in most analysis, as the time and cost horizon is so large.

On Solar Panels: there are some very interesting projects by large environmental service providers underway that use high pressure water or very high temperatures, to separate the glass from metal frame.

I think a similar hurdle are carbon fibres, you can't burn or shred them (carcinogenic micro fibres).

There are some interesting projects that try to clean and reuse the fibres through some kind of chemical baths..but most of the old e.g. wind turbines are just stored at a giant wind turbine graveyard right know.

It's a fascinating field!
