According to the Daily Mail Australia, “The phones were completely disassembled and the internal and external components were sampled using X-ray fluorescence spectrometry, a process that determines the chemical composition of a material. " Of all the phones examined, each of them had at least one of the following substances present: lead, bromine, chlorine, mercury and cadmium. As discussed above each of these materials can cause significant harmful effects to the environment at the end of their life cycle. On the right is shown an example of hazardous materials, the quantity, the position in which they are found between the iPhone 5 and the corresponding classification (5 indicates the most dangerous and 0 the most environmentally friendly). The way cell phones are manufactured contradicts the amount of hazardous chemicals and materials that enter our environment. Waste management is a key issue among cell phones and recommendations need to be made to help sustain the environment. Mobile Muster is an Australian company that recycles mobile phones by separating them from hazardous materials and recycling them into useful items
