Total e-waste—including computers, televisions, and mobile phones—is around 45 million metric tons annually.
...By comparison, PV-waste in 2050 will be twice that figure.
...At the same time, demand for everything from sand to rare and precious metals continues to rise. While supplying only about 1 percent of global electricity, photovoltaics already relies on 40 percent of the global tellurium supply, 15 percent of the silver supply, a large portion of semiconductor quality quartz supply, and smaller but important segments of the indium, zinc, tin, and gallium supplies. Closing the loop on these metals and embracing circular economy concepts will be critical to the industry’s future.
