Innovations like these are critical to the 'clean' energy sector. Just as PVcycle is important to the solar industry, we need to show that, as an industry, we live what we preach. The sustainability of energy storage solutions is an important part of the story. Of course we are seeing plenty of 'second life' solutions for EV batteries, but at some point all batteries will pass their operational usefulness. it is important that we can demonstrate a sustainable and safe way to recycle or reprocess battery products at end of life.
Lead-acid batteries might be the most recycled product in the world, but the industry is still seen as toxic and unclean especially when smelting. Now UK start-up Citrecycle is planning to change that perception with a lead-recycling process that is both ‘clean’ and able to be used in emerging markets such as Africa and India where large-scale smelters are not viable. The company’s process uses natural solvents to leach and purify the lead, producing either lead paste, or metallic lead.
