12 BILLION tonnes of lead-acid batteries (LABs) are in use globally. In Europe, the recycling rate of these batteries is as high as 95% – but the recycling technology is energy intensive. Indeed, pyrometallurgy requires about 18 kWh to recycle a 1 kWh battery. The amount of energy used to recycle one battery far exceeds the amount of energy stored in that battery!
Pyrometallurgy is also highly polluting. For every 10k tonnes of LABs recycled, as much as 4,500 tonnes CO2, 4 tonnes SO2, 2 tonnes NO2 and 1 tonne particulates are produced. Even if abatement systems are employed to minimise pollution, such systems are expensive and cannot always be relied on.
In partnership with the University of Cambridge, Aurelius Technologies bring to the market a patented hydrometallurgical process that is energy efficient, non-polluting, low-cost and scalable. Fenixpb reduces the environmental impact from smelting, while transforming LAB waste into next-generation batteries that are more energy efficient and longer-lasting than current LABs.
