Mobile telephones belong to the fastest updated electronic devices, which generates thousands of tons of waste every year. According to the research by the Nokia company, only very few mobile telephones are recycled after their expiration date, whereas 80 % of Nokia devices are recyclable and contain valuable sorts of material. It is exactly this type of electronic waste that can provide us with various usable material sorts including metals such as copper, iron, nickel, silver and gold. A mobile telephone contains approx. 15-18 % of copper and 3 - 8 % of iron. A significant part of a mobile telephone is composed from miscellaneous types of plastics which are easy to recycle after sorting. Out-of-use mobile telephones belong to the waste group of electrical and electronic devices. Therefore, with respect to the environment, it is necessary to pay an intensive attention to the issue of collecting and recycling this type of devices, since any mobile phone which is not used any more constitutes an environmental burden or the resource of valuable raw materials. This thesis includes a material analysis of selected mobile telephones.
