The U.S. has more than 2 million solar installations. This means there are tens of millions of solar panels on roofs and racking systems. Solar energy is fantastic for reducing carbon emissions and promoting energy independence, but what happens at the end of the panel’s 30-year lifespan?

There is a looming waste management issue as solar systems age and will eventually be decommissioned. Is the U.S. prepared for large-scale solar panel recycling?

“Installations two decades ago are nearing their end of life, and that becomes a challenge for the waste industry,” says Garvin Heath, a senior scientist in the Strategic Energy Analysis Center of the National Renewable Energy Laboratory (NREL). “Because it takes a long time to develop technology and policy and solutions to dealing with end-of-life products, this is something we need to start to address today.”

According to Heath, solar panels could comprise more than 10 percent of global electronic waste by 2050.

Solar panel recycling presents an economic opportunity and can spawn new industries. A study by the International Renewable Agency (IRENA) estimates that by 2050, $15 billion could be recovered from recycling solar panels. There are also repair and reuse opportunities for solar panels that fail prematurely. These repaired solar panels are often sold at a discount, creating opportunities in new markets where affordability is an issue.

What Parts of the Solar Panel Can Be Recycled?
Glass, plastic, aluminum, and silicon comprise 99 percent of the silicon-based solar panels.

Did you know that Americans use 50 billion plastic water bottles each year, with a recycling rate of only 23%? From an environmental standpoint, it brings up numerous concerns. Kicking our bottled water habit can conserve resources, but what are we going to do with the billions of plastic bottles that are recycled? How do we boost stubbornly low plastic bottle recycling rates?

Luckily, Patagonia has been looking at this issue for decades and has made considerable progress in turning plastic trash into polyester fabric for apparel. The company has found a way to actually upcycle plastic bottles, finding a good use for this waste stream by turning it into a higher value goods.

In 1993, Patagonia produced the first polyester fleece jacket from recycled bottles. It had a green tint, from green soda bottles. Now, manufacturing waste, plastic bottles, and worn out clothing is recycled into new apparel, literally closing the recycling loop. Patagonia's product line has expanded from fleece jackets to include 82 products with recycled polyester, including insulated pants, down jackets, and beanies.​
