NyTeknik magazine lists the 33 top start-ups in Sweden, shows an interest in forest-related innovation

The “33-listan” is published by Ny Teknik, a Swedish language science and engineering magazine. Each year they highlight 33 promising innovation-focussed start-up companies, which must be based in Sweden and have been founded less than seven years ago. The 2023 list showed a big emphasis on forest-related companies in the Swedish start-up scene.

Nanocellulose makes battery recycling more efficient

The electrification of our society has led to  a growing need for efficient and sustainable battery recycling methods. In response to this challenge, researchers at WWSC at KTH have achieved a  breakthrough in battery recycling by using nanocellulose in the metal separation. This innovative approach has the potential to significantly simplify the separation of battery metals from other materials, addressing the pressing demand for eco-friendly recycling processes.
