Digital facilities that track wastage down to the gram have brought about behavioural change among users Min Geum-nan walks towards a metal bin beneath her apartment block in Gangdong district, eastern Seoul carrying a small bag of vegetable peelings. She taps her resident card on the reader, the lid swings open, she empties the contents and scans again and a digital screen flashes: 0.5kg. “You have no choice but to pay attention because you can see exactly what you’re wasting,” says Min, who has lived in the complex for 15 years and watched the system arrive in 2020.

The molluscs are decimating food chains in Switzerland, have devastated the Great Lakes in North America, and this week were spotted in Northern Ireland for the first time Like cholesterol clogging up an artery, it took just a couple of years for the quagga mussels to infiltrate the 5km (3-mile) highway of pipes under the Swiss Federal Technology Institute of Lausanne (EPFL). By the time anyone realised what was going on, it was too late. The power of some heat exchangers had dropped by a third, blocked with ground-up shells. The air conditioning faltered, and buildings that should have been less than 24C in the summer heat couldn’t get below 26 to 27C. The invasive mollusc had infiltrated pipes that suck cold water from a depth of 75 metres (250ft) in Lake Geneva to cool buildings. “It’s an open invasion,” says Mathurin Dupanier, utilities operations manager at EPFL. Mathurin Dupanier indicates the water cooling systems that were blocked by the invasive quagga mussels.
