In Rush Towards Renewable Energy One Issue Rarely Spoken Of
(07-17-2022 09:30 AM)MileHighBronco Wrote: California went big on rooftop solar. Now that’s a problem for landfills
Quote:California has been a pioneer in pushing for rooftop solar power, building up the largest solar market in the U.S. More than 20 years and 1.3 million rooftops later, the bill is coming due.
Beginning in 2006, the state, focused on how to incentivize people to take up solar power, showered subsidies on homeowners who installed photovoltaic panels but had no comprehensive plan to dispose of them. Now, panels purchased under those programs are nearing the end of their typical 25-to-30-year life cycle.
Many are already winding up in landfills, where in some cases, they could potentially contaminate groundwater with toxic heavy metals such as lead, selenium and cadmium.
Sam Vanderhoof, a solar industry expert and chief executive of Recycle PV Solar, says that only 1 in 10 panels are actually recycled, according to estimates drawn from International Renewable Energy Agency data on decommissioned panels and from industry leaders.
The looming challenge over how to handle truckloads of waste, some of it contaminated, illustrates how cutting-edge environmental policy can create unforeseen problems down the road.
“The industry is supposed to be green,” Vanderhoof said. “But in reality, it’s all about the money.”
Why not recycle? Turns out there are issues there, too.
Quote:But as California barreled ahead on its renewable-energy program, focusing on rebates and — more recently — a proposed solar tax, questions about how to handle the waste that would accrue years later were never fully addressed. Now, both regulators and panel manufacturers are realizing that they don’t have the capacity to handle what comes next.
“This trash is probably going to arrive sooner than we expected and it is going to be a huge amount of waste,” said Serasu Duran, an assistant professor at the University of Calgary’s Haskayne School of Business in Canada. “But while all the focus has been on building this renewable capacity, not much consideration has been put on the end of life of these technologies.”
Quote:Although 80% of a typical photovoltaic panel is made of recyclable materials, disassembling them and recovering the glass, silver and silicon is extremely difficult.
“There’s no doubt that there will be an increase in the solar panels entering the waste stream in the next decade or so,” said AJ Orben, vice president of We Recycle Solar, a Phoenix-based company that breaks down panels and extracts the valuable metals while disposing of toxic elements. “That’s never been a question.”
The vast majority of We Recycle Solar’s business comes from California, but the company has no facilities in the state. Instead, the panels are trucked to a site in Yuma, Ariz. That’s because California’s rigorous permitting system for toxic materials makes it exceedingly difficult to set up shop, Orben said.
Quote:Recycling solar panels isn’t a simple process. Highly specialized equipment and workers are needed to separate the aluminum frame and junction box from the panel without shattering it into glass shards. Specialized furnaces are used to heat panels to recover silicon. In most states, panels are classified as hazardous materials, which require expensive restrictions on packaging, transport and storage. (The vast majority of residential solar arrays in the U.S. are crystalline silicon panels, which can contain lead, although it’s less prevalent in newer panels. Thin-film solar panels, which contain cadmium and selenium, are primarily used in utility-grade applications.)
Orben said the economics of the process don’t make a compelling case for recycling.
Only about $2 to $4 worth of materials are recovered from each panel. The majority of processing costs are tied to labor, and Orben said even recycling panels at scale would not be more economical.
Most research on photovoltaic panels is focused on recovering solar-grade silicon to make recycling economically viable.
That skews the economic incentives against recycling. The National Renewable Energy Laboratory estimated that it costs roughly $20 to $30 to recycle a panel versus $1 to $2 to send it to a landfill.
While not toxic like solar panels, when a wind turbine is decommissioned and torn down, the blades wind up in landfills - there is no way to recycle them, given current technology.
All the talk about renewables is on the front end, with little thought given to what happens when that tech is at the end of its lifespan.

Uhhhh,
And what exactly is “renewable”? Lead? Silver? Lithium? Cadmium?!?
Errrrt, no. This is loonie-speak. Bury it all and hope it reproduces or something?
This is the thoughts of ideologues and simply science deniers.
We’ll simply destroy this planet, wrecking it one strip mine after another to fulfill this idiotic “carbon zero” utopia.
Course all them Cat diesels will be doing the real work.
Dumb de Dumb Dumb.
Y’all starting to figure this out yet?!?
Suckers
