Spark Award 2024: procedure for recycling rare earth metals receives award

The prize for the most promising invention of the past year goes to Marie Amélie Perrin and Victor Mougel. They have developed a method that enables rare earth elements to be efficiently recovered from electrical waste.

New type of weather radiosonde can find its way back

Some 80% of weather radiosondes – remote measurement instruments containing plastic, batteries and electronic parts – end up lost in nature after one flight. But a startup created by an EPFL master’s student is set to change that with a new, ultra-lightweight “glidersonde” that can automatically return to where it was launched.

Mining rare earth metals from electronic waste

ETH researchers are developing a process inspired by nature that efficiently recovers europium from old fluorescent lamps. The approach could lead to the long-awaited recycling of rare earth metals.

First spin-off at the SLF

The RAMMS software for modeling avalanches, debris flows and rockfalls is being incorporated into a specially founded AG.

This researcher reads rivers

Jessica Droujko’s start-up, Riverkin, measures the water quality of freshwater ecosystems and helps quantify and respond to risks such as floods and pollution. Thanks to an ETH Pioneer Fellowship, her work is now picking up speed.

How the ETH start-up ecosystem works

In 2023, a record-breaking 43 spin-offs were founded at ETH Zurich. Why are ETH spin-offs so successful? Tracing the typical path of a start-up.
