Every year approximately 40,000 tonnes of a hazardous waste known as spent pot-lining is generated by Australia’s aluminium industry. It contains significant levels of leachable cyanide and fluoride and is currently being stored awaiting a suitable treatment technology. This project will develop a novel low-energy and low-cost process for extracting the fluoride as a useful aluminium fluoride product that can be recycled back into the aluminium industry; destroy the cyanide; and recover other components for use in the metallurgical industry. If commercialised the benefit will be an end to the stockpiling of spent pot-lining in Australia, a more sustainable aluminium industry, and protection of the world’s natural fluoride resources.

澳大利亚的铝工业每年产生约4万吨被称为废电解槽内衬的危险废物。 它含有大量的可沥滤氰化物和氟化物，目前正在储存，等待适当的处理技术。 该项目将开发一种新的低能耗和低成本工艺，将氟化物作为有用的氟化铝产品提取，可回收回铝工业;销毁氰化物;并回收其他成分用于冶金工业。 如果将其商业化，其好处将是结束澳大利亚的废罐衬储存，一个更可持续的铝工业，以及保护世界天然氟化物资源。
