Properly Dispose of Batteries
Almost everyone uses and discards batteries into the waste stream. Although waste batteries are a small amount of the solid waste stream, they are a concentrated source of some types of heavy metals. The main constituents of concern for human health and the environment include: cadmium, lead and mercury. Since 1993, domestically produced alkaline and carbon zinc batteries contain no added mercury and are essentially mercury-free. Since early 1995, rechargeable alkaline batteries contain no added mercury and are essentially mercury-free.
