Federal scientists are warning that a wave of waste from solar panels could catch landfills off guard unless researchers figure out ways to recycle it. In a study published last week in Nature Energy, analysts at the National Renewable Energy Laboratory said roughly 8 million tons of solar photovoltaic panels are expected to hit landfills globally by the end of this decade, rising to 80 million by midcentury, when they could account for about 10% of all electronic waste.
