  • Many plans designed to deal with climate change depend on the use of clean energy from the sun, or solar power.
  • 2
  • But the equipment necessary for solar power sometimes gets damaged or wears out.
  • 3
  • These solar panels often end up as waste in landfills.
  • 4
  • A business based in Yuma, Arizona, is trying to deal with what its founders call a tsunami of solar waste.
  • 5
  • The company is called We Recycle Solar.
  • 6
  • Workers move large numbers of solar panels with special machines, then lift each out by hand to begin separating by maker and model.
  • 7
  • Some panels only have a few cracks in their glass.
  • 8
  • These panels can be reused, said company chief Adam Saghei.
  • 9
  • The panels that do not go to testing and resale instead go to a special area where glass, metals, and other materials with value are separated.
  • 10
  • Solar panels are built to survive many years of bad weather, so it is difficult to take them apart.
  • 11
  • Separating the glass without it breaking, for example, is difficult.
  • 12
  • But We Recycle Solar uses special robotic devices that can do the work successfully.
  • 13
  • Some of the highest value materials in solar panels are copper, silver, aluminum, glass, and crystalline silicon.
  • 14
  • For Saghei, the idea for the company came in 2017.
  • 15
  • He was working in the computer electronic waste sector.
  • 16
  • He saw solar panels spread across roofs and wondered where the panels would go in the future.
  • 17
  • He said he realized that green technology does not stay green once it is no longer being used.
  • 18
  • Copper is one metal the recycling process produces, said Dwight Clark, director of recycling technology at We Recycle Solar.
  • 19
  • Clark said there is not a lot of copper in each solar panel.
  • 20
  • But when the company recycles around 4500 kilograms of solar panels in an hour, the company can get over a hundred kilograms of copper.
  • 21
  • By 2050, solar panel waste will total some 78 million tons worldwide, said Mool Gupta of the University of Virginia.
  • 22
  • The reason recycling and recovery is not very strong yet, Gupta said, is that companies do not want to pay the $30 per panel cost when it costs only $1 to send it to a landfill.
  • 23
  • Garvin Heath is a renewable energy expert at the U.S. Department of Energy.
  • 24
  • He said the cost to recycle should not be more than the cost to put solar panels in landfills.
  • 25
  • He said consumers should not have to pay anything and recycling businesses should not suffer financial losses.
  • 26
  • Other companies are starting to get into the business.
  • 27
  • Solarcycle, a new company based in Odessa, Texas, raised $30 million earlier this year.
  • 28
  • And Solarpanelrecycling.com is connected to electronics recycler PowerHouse Recycling.
  • 29
  • The European Union has rules that require recycling of electronic waste under its Waste Electrical and Electronic Waste Directive (WEEE).
  • 30
  • Market researcher Visiongain estimates the global market for solar panel recycling at $138 million for last year and growing fast.
  • 31
  • Jack Groppo of the University of Kentucky says people have to stop sending solar panels to the landfill as soon as possible.
  • 32
  • "Once the solar panels go into the landfill, they're gone unless we go back and mine the landfill," he said.
  • 33
  • Groppo estimates that in 20 years people will mine landfills to get valuable materials in the solar panels.
  • 34
  • But he said it makes more sense to separate the panels at their retirement instead.
  • 35
  • The Yuma facility can process 7,500 panels in a single day.
  • 36
  • As of early June, it estimates more than 650,000 tons of carbon dioxide waste production have been avoided.
  • 37
  • It is reusing about 60 percent of the panels that come in.
  • 38
  • The company plans to open another recycling center next to a large solar manufacturer in the southeastern part of the country.
  • 39
  • For now, solar recycling companies are still looking for a way to make money.
  • 40
  • But Gupta said these profitability issues are temporary.
  • 41
  • Researchers are hard at work on solving them, he said.
  • 42
  • He added, "Too many lives are lost to pollution and solar is one of the top solutions."
  • 43
  • I'm John Russell.
