Does anyone know of a place to take old smoke/carbon monoxide detectors to be recycled? The manufacturer won’t take them back (they would if they were just smoke detectors, though). The city utilities said they don’t recycle them and to just put them in the garbage. They have trace amounts of radioactive Americium 241 as well as all the plastic and electronics, so I’d rather recycle than trash them. I’d be willing to take them somewhere locally or mail them to a recycler, if only I can find one! Any ideas?
