About Viridis Recycling
Viridis Recycling is a Fraunhofer spin-off specializing in the recycling of lithium-ion batteries. The company processes production scrap as well as end-of-life batteries of NMC, NCA and LFP chemistries in all geometries and sizes. After a material-specific pretreatment – sorting, discharging and disassembly – the cells pass through the proprietary HydroPulse™ process, which mechanically separates the components using aqueous pressure waves. Multi-stage sorting processes produce highly pure material fractions, which are processed by washing, centrifugation and sieving into active materials for direct reuse in new batteries. With up to 95 % material recovery, 50 % lower CO2 emissions and up to 90 % energy savings compared to pyrometallurgical processes, Viridis Recycling positions itself as a partner for the circular economy and raw material recovery in electromobility.
