Study Claims Discarded Solar Panels Create More Toxic Waste Than Nuclear Plants (nationalreview.com)
Templer421 shares an article from National Review:
A new study by Environmental Progress warns that toxic waste from used solar panels now poses a global environmental threat. The Berkeley-based group found that solar panels create 300 times more toxic waste per unit of energy than nuclear-power plants. Discarded solar panels, which contain dangerous elements such as lead, chromium, and cadmium, are piling up around the world, and there's been little done to mitigate their potential danger to the environment. "We talk a lot about the dangers of nuclear waste, but that waste is carefully monitored, regulated, and disposed of," says Michael Shellenberger, founder of Environmental Progress, a nonprofit that advocates for the use of nuclear energy. "But we had no idea there would be so many panels -- an enormous amount -- that could cause this much ecological damage." Solar panels are considered a form of toxic, hazardous electronic or "e-waste," and according to EP researchers Jemin Desai and Mark Nelson, scavengers in developing countries like India and China often "burn the e-waste in order to salvage the valuable copper wires for resale. Since this process requires burning off plastic, the resulting smoke contains toxic fumes that are carcinogenic and teratogenic (birth defect-causing) when inhaled."
A spokesman for the Solar Energy Industries Association argues that the study is incorrect, and that in fact solar panels are "mainly made up of easy-to-recycle materials that can be successfully recovered and reused at the end of their useful life."

The "300 times more toxic waste than nuclear power" requires considering one kilogram of solar panel as being toxic waste equivalent to one kilogram of spent reactor fuel. This is a preposterous comparison.
Furthermore it treats all solar panels as being as being the same source of hazard. Cadmium telluride panels are a special concern for disposal, but they are 2.5% of the global market and only used in special situations, whereas 95% of production is silicon panel and not toxic at all.
The disposal of solar panels is a valid concern that must be addressed, like the disposal of all electronics, and solid waste generally, but this framing is wildly deceptive.

While solar panels do pollute a little if not properly disposed of, as far as I know, lead, cadmium and chromium are all pretty easy to recover by melting down the panels. If you are stupid enough to burn plastic, you get what you get, but as a kid we burned plastic from time to time and we didn't suffer any ill effects.
The problem with these articles is they assume the worst case for the disposal of panels while assuming the best case for nuclear waste. It is relatively trivial to recycle lead, cadmium and chromium into new solar panels, and they require no more than respirators and proper gloves and ventilation/filtration to work with, whereas spent nuclear fuel is quite difficult and dangerous to work with and there is no real east way to recycle spent nuclear waste. Alternatively, you could bury the worlds entire supply of solar panels in a landfill and it would be pretty harmless, assuming the landfill was modern and properly lined and isolated from the ground water (the lead, cadmium and other heavy metals are usually laminated between layers of glass, so even breaking the panels only exposes a small fraction of the total heavy metal content).
As first world societies, if we are really concerned for the environment, we should slap a recycle fee onto every panel sold and then require that they be recycled in a first world country with felony prison time for exporting un-recycled e-waste to the third world (we already do this more or less for many other things that need to be recycled).
If you disagree, please post your argument. (-1, Overrated) isn't your personal censorship tool for views you don't like
Try Recyling Nuclear waste. The stupid article simply says 300 times as much toxic waste as a nuclear power energy unit. In what units? volume, molarity, mass, rads, toxicity, ease of neutralization?
the article is Right wing rubbish.
No it's not like there isn't a grain for truth to be gleaned here but such glib quantifications are . give away that this article itself is utter crap
Some drink at the fountain of knowledge. Others just gargle.
Wrong. Silicon plate panels, i.e., the ones nobody wants to purchase anymore because they're ungodly expensive in comparison to alternatives, degrade at 0.5-0.7% of power capacity per year.
Thin film panels, i.e., the ones everyone is currently buying due to cost advantages, degrade at 1-1.5% of power capacity per year.
After you've lost 20% of your capacity and can no longer satisfy your design load, you're not going to be happily touting how you can still get power out of your panels.
Who says? The NREL, based upon about 1700 data points (Fig. 2 of linked report).
Don't sell me bullshit either.
I hate to say it, but this is (1) not a "study"-- it's an opinion article, and
(2) the opinion expressed is unmitigated bullshit.
From the purported "study": "Solar panels contain toxic metals like lead, which can damage the nervous system, as well as chromium and cadmium, known carcinogens.
Notice that weasel word--materials "like" lead. Solar panels don't contain lead. Period. But the "study" didn't actually say they contained lead, did it? It said they contain materials "like" lead. What does that actually mean? Uh, I don't think it actually means anything whatsoever.
Likewise, solar panels don't contain chromium (you'd think this guy would go after cars, wouldn't he? They actually do use chromium.). And, while one type of panel does use cadmium (albeit in micron thicknesses)-- the vast majority of low cost solar panels sold are silicon solar cells, which do not contain cadmium.
Overall conclusion: this is not a "study," this is bullshit, pure and simple,
