Recycling end-of-life solar panel, wind turbine is big waste business

The growing importance of wind and solar energy to the U.S. power grid, and the rise of electric vehicles, are all key to the nation’s growing need to reduce dependence on fossil fuels, lower carbon emissions and mitigate climate change.

But at the same time, these burgeoning renewable energy industries will soon generate tons of waste as millions of photovoltaic (PV) solar panels, wind turbines and lithium-ion EV batteries reach the end of their respective lifecycles.

As the saying goes, though, one man’s trash is another man’s treasure. Anticipating the pileup of exhausted clean-energy components — and wanting to proactively avoid past sins committed by not responsibly cleaning up after decommissioned coal mines, oil wells and power plants — a number of innovative startups are striving to create a sustainable, and lucrative, circular economy to recover, recycle and reuse the core components of climate tech innovation.

Wind and solar energy combined to generate 13.6% of utility-scale electricity last year, according to the U.S. Energy Information Administration (EIA), and those numbers will undoubtedly rise as renewable energy continues to scale up. Some leading utilities across the nation are far ahead of that pace already.

Meanwhile, sales of all-electric vehicles rose to 5.8% of the total 13.8 million vehicles Americans purchased in 2022, up from 3.2% in 2021. And with the Environmental Protection Agency’s newly proposed tailpipe emissions limits and power plant rules, EV sales could capture a 67% market share by 2032 and more utilities be forced to accelerate their power generation transition.

Solarcycle is a prime example of the companies looking to solve this climate tech waste problem of the future. Launched last year in Oakland, California, it has since constructed a recycling facility in Odessa, Texas, where it extracts 95% of the materials from end-of-life solar panels and reintroduces them into the supply chain. It sells recovered silver and copper on commodity markets and glass, silicon and aluminum to panel manufacturers and solar farm operators.

“Solar is becoming the dominant form of power generation,” Solarcycle CEO Suvi Sharma said, citing an EIA report stating that 54% of new utility-scale electric-generating capacity in the U.S. this year will come from solar. “But with that comes a new set of challenges and opportunities. We have done a phenomenal job making solar efficient and cost-effective, but really have not done anything yet on making it circular and dealing with the end-of-life [panels].”

The average lifespan of a solar panel is about 25 to 30 years, and there are more than 500 million already installed across the country, Sharma…
