Most of the phones are either are refurbished and sold in the US or sent for reuse in markets such as Asia, Africa, and India. Your old cell phone could give someone in the third world their first glimpse of the internet!
It is environmentally friendly to provide a phone for reuse by someone else. If your phone cannot be resold and reused by someone else because it is broken or badly damaged and is therefore deemed by the phone buyer to be 'Beyond Economical Repair' then it is disposed of in an environmentally friendly way so it doesn't end up in a landfill site.
Did you know that you cannot throw your old cell phone in the trash; not only is against the law, but it is harmful to the environment. Cell phones contain many dangerous persistent toxins that accumulate in the environment, including arsenic, antimony, lead, beryllium, copper, cadmium, nickel and zinc. Always ensure you recycle your cell phone through a professional organisation that is regulated to ensure they are disposed of correctly.
