"One of the main problems with the current linear economy’s production and consumption model, as opposed to a sustainable circular economy system, is planned obsolescence. Planned or programmed obsolescence refers to the deliberate shortening of a product’s useful life by the manufacturer in order to increase consumption.
Planned obsolescence is a serious environmental problem for the planet. Every year, up to 50 million tons of electronic waste are generated, a very high percentage of which – around 85% - is usually discarded randomly, ending up in waste tips in developing countries, creating a risk for the environment and the health of people, animals and plants."
One example: non replaceable batteries in smartphones. The used to be standard, nowadays only small manufacturers as Fairphone use them.
