In recent years, the technological development of electronic devices has led to a rapid increase in the amount of electronic waste, which is largely disposed of improperly and causes massive damage to the environment and people. The enormous increase in these mountains of waste is partly due to the phenomenon of obsolescence. On the one hand, planned or condoned obsolescence leads to faster wear and tear of important components and thus to an avoidable reduction in service life. On the other hand, the ever shorter succession of innovations leads to an increasing proportion of functional obsolescence because older and new devices and functions are no longer compatible. In addition to these forms of unsustainable development caused by producers, consumers are also making a decisive contribution to exacerbating the problem by disposing of fully functional technical artefacts. Although the phenomenon of obsolescence is many decades old, it has recently been attracting more and more attention. In particular, the suspicion that planned obsolescence is at play when devices break shortly after the warranty expires is often the subject of discussion and scientific research. The use of inferior materials also reduces the durability of appliances. However, it is not only the economy but also consumers who contribute to the obsolescence of products by disposing of devices that work perfectly because, for example, a new generation has come onto the market or the product has become outdated.
