Sagot :

2) Among the chemical elements used in smartphones are copper, gold and silver for wiring, lithium and cobalt in the battery, and aluminium, silicon, oxygen and potassium in the glass screen.

3) it makes sense to recycle our handsets because most cities, states, and countries don’t want you to throw old phones away. This is because electronics have many toxic components that can leak harmful chemicals into the ground if they sit in a landfill.
