This module uses the example of the smartphone to discuss the requirements and consequences of the mass production of electronics. A smartphone contains more than sixty different raw materials, including rare earth metals. The extraction of these raw materials is either carried out with a high technological and corresponding energy input or under exploitative conditions, ignoring all minimum social standards. In order to illustrate the problem of wasting non-renewable raw materials, the mobile phone is used to research and discuss the origin of rare earth metals, their extraction methods and the associated environmental destruction as well as issues of global justice. This module also uses the example of waste disposal in Accra to show how Western industrialised countries solve the majority of their waste problems. The appliances that are often illegally exported to developing countries and their improper disposal not only have dramatic consequences for the people affected and the environment. The way in which the components of the appliances are separated also leads to an enormous loss of valuable raw materials, which are lost to entropy. An alternative is demonstrated using the example of a state-of-the-art recycling plant in Germany.
