Summary

In the natural world, the waste from one species is the food for another species. In the same way, industrial resources can be optimized by looking at how ecological systems operate. This article describes how the principles of “Industrial Ecology” are used to realise a safe, sustainable solution for spent potlining (SPL). This solution sees all of the SPL detoxified and refined into products that have genuine value in energy intensive industries. The solution has been proven over fifteen years with more than 180,000 tonnes of SPL from four aluminium smelters completely transformed, with no residual materials, and sold in a developed market.
