1.1.3 Treatment of Waste Battery
The waste battery is negligible, but its harm is very big,
the battery contains mercury, cadmium, lead and other
heavy metal substances, endanger human health. If the waste
battery mixed with domestic waste in a landfill , as time
passes, the heavy metals may contaminate groundwater and
soil. So need to deal with batteries of the waste phones
reasonably.
No landfill. Because the heavy metal of waste batteries
pollute water and soil through the osmosis.
No incineration. Because steam formed by incineration
may catalyze the formation of harmful gases at the same
time, resulting in the pollution of the atmosphere.
No compost. May lead to excessive levels of heavy
metals in the material.
Do not throw away the waste battery, so as not to pollute
the environment.
