Batteries or accumulators are any source of electrical energy generated by direct conversion of chemical energy and consisting of one or more primary battery cells (non-rechargeable) or consisting of one or more secondary battery cells (rechargeable).
Most types of batteries contain toxic heavy metals, including nickel, cadmium and mercury. All of these metals can be recovered and re-used. Recycling batteries is good for the environment as it keeps them out of landfill, where heavy metals may leak into the ground, causing soil and water pollution and endangering animal and plant life. If batteries are incinerated with household waste, the heavy metals inside them cause air pollution.
That’s why you should not put dead batteries in the trash. Batteries and accumulators inside electrical and electronic equipment which can be easily removed by the user must be disposed in specific containers for separate collection of this waste.
In Spain, you can always dispose of waste portable batteries:
1º In civic amenities.
2º In shops that sell batteries.
3º In other separate collection bins for waste batteries you can find in street furniture, public buildings, etc.
You can find available collection points here.
Your collaboration is essential to recycle this waste!
