Recycling solar panels will become an important part of the renewable energy revolution as older panel reach the end of their useful life.
. By the 2050s, the volume of solar panel waste will rise to at least 5 million metric tons a year. China, the world’s biggest producer of solar energy, is expected to have retired a cumulative total of at least 13.5 million metric tons of panels by 2050 — the largest quantity among major solar-producing nations and nearly twice the volume retired in the US by that time.
But what else is inside a solar panel? Lead, cadmium, and selenium, among other things we don’t want in our groundwater, as they breakdown in landfills over years and decades. In 2020, the International Energy Association determined the risk of pollution when a solar panel is consigned to a a landfill is low, but its findings did not constitute an endorsement of using landfills. It said affirmatively that recycling would “further mitigate” environmental concerns.
Gosh, what might happen if there was an economic benefit associated with keeping carbon dioxide out of the atmosphere? Don’t be silly. That would severely damage the profitability of fossil fuel companies, and we couldn’t have that, now could we? Profits must always take priority over sustainability. People learn that the very first week of B School.
