Waste management, recyclers, and electronics manufacturers are reminding consumers that it is a bad idea to throw out devices that contain lithium-ion batteries. California was compelled to start an awareness campaign after numerous fires at waste facilities, while incidents in New York ranged from batteries blowing up in garbage trucks to five-alarm fires that resulted in railroads being shut down. Last year, 65% of waste facilities fires in California began with lithium-ion batteries. And when one goes, others can, too. “If there are multiple batteries there, you will have not just a fire, you will have explosions,” said Carl Smith, CEO and president of Call2Recycle, a national recycling program funded by battery manufacturers.
