Each year, the total amount of electronic equipment society uses grows by 2.5 million tonnes. As most of this equipment cannot be reused or recycled, this is constantly adding to the world’s growing mountain of e-waste. In 2019, 53.6 million tonnes of e-waste was generated globally and by 2030, it is likely to increase to 74.7 million tonnes. In an effort to minimise this problem, a team of scientists at Germany’s Karlsruhe Institute of Technology (KIT) have developed an experimental electronic display that can be composted when no longer needed. It is likely that this technology will be most applicable in short-lifecycle applications, such as disposable skin-worn sensors that monitor patients’ conditions, or food packaging that indicates when it has gone off.
