Researchers at Otto von Guericke University Magdeburg developed a method to reduce noise from EV power electronics using granulate made from recycled car tyres. In lab tests, the approach lowered noise by 6.5 decibels in the critical frequency range and reduced component cover vibrations by up to 9.7 decibels.

Retired lithium-ion batteries often retain up to 80% capacity, but lack of reliable data prevents reuse and recycling. Researchers from Chalmers University of Technology, writing in Nature Reviews Clean Technology, identify AI as a solution to overcome this data barrier and capture lost economic and climate benefits.

Cornell University researchers developed a direct electrode-to-electrode regeneration method that restores spent lithium-ion cells to 95% of original capacity while cutting recycling costs by 56%. The technique dissolves the insulating layer on electrodes, skipping destructive smelting or acid processing.

GR3N raised €15.5 million in Series B funding. The company focuses on chemical recycling of PET plastic waste. The funding round will support the scaling of its depolymerization technology for circular polyester production.
