here in Central Europe batteries in the trash can are the cause for massive dumpster fires and explosions (not that often, but there was one just last month, took several days to extinguish the fire [0])
This is not just a central europe problem. A bit further west people throw them in the trash as well. Fun and smelly since the garbage truck drivers usually notice it when driving and then dump all trash on the street.
