31. Unused mobile phones pose a threat to the environment by adding to the growing volume of toxic waste in our country’s landfills. Because mobile phones are full of dangerous pollutants, the possibility exists for the toxins in the phones to be released into the air and ground water. Furthermore, if not stored in the correct conditions, old and unused phone batteries may leak and release toxic chemicals into homes. Old mobile phones are recycled by donating them to charities, reselling or shredding them into scrap. When the phones are scrapped, the metal and plastic components are separated. The metals are sold to metal refineries where they are melted and purified for reuse, while the plastics are turned into fuel replacement for oil or turned into plastic benches and fences.
