Company with Texas solar panel recycling plant plans next facility out of state

A company that recycles solar panels announced Thursday that it would build a $344 million factory in northwest Georgia, for the first time expanding to making new glass for panels.

Arizona-based Solarcycle, which was founded in 2022 and opened its first recycling facility in Odessa, Texas, said it would hire more than 600 workers in Cedartown, about 50 miles (80 kilometers) northwest of Atlanta, for a factory opening in 2026. Earlier this month, the company opened a headquarters, research lab and second recycling facility in Mesa, Arizona, hiring more than 100 people.

Solarcycle says its automated recycling process can extract materials worth 95% of a solar panel's value, including silver, silicon, copper and aluminum. Solarcycle said would be able to recycle 1 million solar panels in Cedartown. Then it plans to make enough glass to make solar panels that could produce 5 gigawatts a year of electricity, using a combination of recycled glass and raw material. Solarcycle said it would sell the glass to companies that make solar panels in the United States.

Last week, South Korean-owned Qcells, which makes solar panels in nearby Dalton, said it had contracted with Solarcycle to recycle decommissioned Qcells panels in the United States. Solarcycle said it has similar contracts with more than 40 other solar energy companies.

The company chose Cedartown to be close to domestic solar panel makers, spokesperson Brooke Havlik said, saying the location offers rail and shipping infrastructure and workers.

Solarcycle has raised tens of millions of dollars from private investors for expansion, and Havlik said the Cedartown factory would largely be funded through private investment.

The company has also received $1.5 million from the U.S. Department of Energy to fund research and development, and Havlik said the companies that buy Solarcycle’s glass are expanding, “largely driven by incentives and tailwinds” created by Biden administration actions.

Democratic U.S. Sen. Raphael Warnock credited President Joe Biden’s clean energy and healthcare law, the Inflation Reduction Act, with spurring Solarcycle’s investment, saying Georgians continue “to reap its benefits.”

Gov. Brian Kemp, though, has argued that Georgia's business environment deserves credit for attacting companies like Solarcycle and Qcells. Georgia Economic Development Commissioner Pat Wilson said the company approached state economic recruiters at a trade show.

“Solarcycle provides a critical piece to the integrated solar supply chain we are building in Georgia,” Wilson said in a statement.

Solarcycle didn’t say how much workers will make, only describing pay and benefits as “competitive.”

The company could qualify for $9 million in state income tax credits, at $3,000 per job over five years, as long as workers make at least $31,300 a year. The company will also receive property tax breaks from Cedartown and Polk County, said Chris Thomas, the president and CEO of the Development Authority of Polk County, but he did not provide an estimate. Solarcycle said Georgia will also pay to train workers.

Researchers at Rice University have developed a new technique to efficiently recycle electronic waste and harvest critical minerals using rapid heating.

Most electronic devices use flame-retardant plastic. The plastic is formulated from a critical metal called antimony.

However, recapturing antimony is typically a challenging task since it first has to be released from the plastic. As it is released, other compounds can form, such as organic bromides, which are toxic and difficult to capture. However, the organic bromides can also be reused and have applications in industrial chemicals when safely captured.

“Conventionally heating the plastic releases the antimony in a volatile and difficult-to-collect form as well as creating and releasing hazardous organic bromide compounds,” Leo Haoxin Ye, first author of the paper and a graduate student at Rice, said in a news release. “Other options are risky or more impractical, such as using strong acids, organic solvents or multistep treatment options.”

To address this issue, leading Rice chemistry professor James Tour, Ye and their team adapted Tour’s flash Joule heating technique, which heats materials to hundreds of degrees Celsius in milliseconds, according to Rice.

The team ground up flame-retardant plastic waste and placed it between two sheets of electrically heated carbon paper before using what’s known as isothermal-clamped flash Joule heating to release and collect the antimony.

The team found that limiting the time the plastic spent in the high temperature range dramatically reduced the production of the hazardous organic bromide compounds. The plastic remained between 200 degrees and 500 degrees Celsius for only 9.4 milliseconds, according to Rice.

Through the process, the team recovered 90 percent of antimony from tested materials and converted 83 percent of the bromide into hydrogen bromide. Their findings were published this month in the journal Nature Chemical Engineering.

“Isothermal-clamped flash Joule heating could improve the speed, safety and practicality of antimony recovery from discarded flame-retardant plastics,” Tour added in the release. “This represents an important step forward to conserving and reusing our critical antimony supply while also regenerating bromide salts for reuse.”

The study noted that the world is currently trending toward producing 82 million metric tons of flame-retardant plastic waste by 2030, which adds to the fact that e-waste is the fastest-growing solid waste stream in the world.

The research was funded by the Air Force Office of Scientific Research and the U.S. Army Corps of Engineers.
