This double lesson focuses on the problem of the increasing amount of electronic waste and the unresolved issue of recycling. After a discussion following the film, a charging cable or a pair of headphones is used to calculate the quantities of metals and rare earths used. The pupils are asked to extrapolate this to get a feel for the relevance of even small quantities. Finally, another film offers an alternative solution to the disposal situation. This is a documentary about the first and so far only company in Germany that buys up mobile phones and recycles the copper they contain (urban mining).

For this lesson, the lecturer must provide the following:
* Laptop
* Projector
* Speakers
