Bought today, thrown away tomorrow. Whether it's a printer, mobile phone, or TV, almost all of us have experienced that products are ready for the trash shortly after the warranty expires. Repairing them is not worth it or is simply not possible. Manufacturers deliberately ensure that their products break down early so that we consumers consume more. This mass phenomenon, known as planned obsolescence, generates pointless mountains of waste, consumes enormous resources, and costs each consumer about 110 euros per month. Christian Kreiss is the first scientist to systematically address the planned reduction of product lifespan and proves that large corporations worldwide employ this sales strategy. Planned obsolescence is deeply embedded in our economic and social system and is just one of the tricks used by big corporations.
