Los Angeles makes it super easy to recycle hazardous waste. I was able to drop off my old car battery (and clense myself of the last reminders of an unpleasant experience) at a place in Sun Valley - just to the north of the Burbank airport. It took all of about 1 minute and was FREE! They had a drive through arrangement and they only ask 1 question: your zip code, since the service is only available to residents of Los Angeles city or county. They have 5 permanent S.A.F.E. recycling centers available for residential waste.
