The aim of this project is to develop a safer and cheaper alternative to the current pyrometallurgical processing method applied to the recycling of lead acid batteries. This will be done by developing a solvent based, low temperature process. The process will use low cost, sustainable and biodegradable solvents to dissolve a variety of lead compounds found in waste battery streams. Dissolved lead can then be recovered chemically or electrochemically as lead oxide or metal, both of which are useful materials for the manufacture of new batteries. This technology could be well positioned to replace the improvised furnaces used by informal battery recyclers that pose a significant pollution hazard in developing countries.

该项目的目的是开发一种更安全、更便宜的替代方法，替代目前用于铅酸电池回收的火法冶金处理方法。这将通过开发基于溶剂的低温工艺来完成。该工艺将使用低成本、可持续且可生物降解的溶剂来溶解废电池流中发现的各种铅化合物。然后可以通过化学或电化学方式将溶解的铅回收为氧化铅或金属，这两种材料都是制造新电池的有用材料。这项技术可以很好地取代非正式电池回收商使用的简易熔炉，这些熔炉对发展中国家造成了严重的污染危害。
