Our Topic

Most electric and electronic products of the 21st century have a negative environmental impact during production, use phase and at end-of-life. The current trend is that the use phase of electric products stagnates or shortens continuously – despite of constant technological progress – while the number of products per person is growing. This leads to a fast growth of e-waste. A longer use phase can increase the resource efficiency and reduce the environmental impacts of electronics significantly. A great deal of discussion revolves around the so-called “obsolescence”, a shortage of product lifetimes or serviceable life for functional, qualitative or socio-cultural reasons. Research on these phenomena often focuses either producers or consumers and overemphasizes the role of cognitive aspects and decision making. It still lacks an integrative framework that reconstructs how obsolescence is inscribed into the material culture of modern societies and the interaction of economic paradigms, production and consumption practices and political frameworks.


Our goal

The five-year interdisciplinary research group aims to investigate the multiple and interacting causes for shortened product lifetimes and to develop an integrative concept to explain the societal production of obsolescence in electronics.  Perspectives from engineering, economic science and sociology will be combined to explain obsolescence in its various forms and to develop strategies to enlarge use phases and reduce the amount of products consumed.
