Info: Batteries may contain heavy metals that are harmful to the environment and fatal to the human organism.
Avoiding/reducing: If possible, use battery-free devices, e.g. with solar cells. Use modern rechargeable batteries (Ni-MH batteries, lithium batteries).
Recycling/environmentally sound disposal: Dry batteries are heated to 700 °C in a pyrolysis plant. Organic components (paper, cardboard, plastic) are incinerated. The metals iron, manganese and zinc are recovered by smelting, mercury by distillation (www.batrec.ch).
