Spent pot lining, the used inner lining of reduction cells in which aluminium is smelted, is one of the most significant waste streams in the aluminium industry.
The new facility is an important part of EGA’s commitment to reducing and re-using industrial waste, according to a statement from EGA.
“SPL is a global challenge for our industry, but over the past decade at EGA we have been able to turn this waste into value in the UAE. I am pleased that EGA now has its own infrastructure to transform SPL into a useful industrial feedstock, securing this solution and our partnerships with UAE cement companies for the long term,” said Abdulla Kalban, Managing Director and CEO of EGA.
The facility will be used to pre-treat spent pot lining so it is ready to be used by cement companies in the UAE as an alternative feedstock, said the company, which has supplied over 41,000 tonnes of spent pot lining to UAE cement companies, reducing stockpiles from previous years.
Worldwide, the aluminium industry produces over 1 million tonnes of spent pot lining every year according to industry experts, with much kept in indefinite storage without economic use.
The company had previously worked with specialist third parties to process SPL before delivery to cement companies, increasing transportation distances and processing costs. The company is also supplying most of its carbon dust, another important by-product stream, to UAE cement companies for use as a fuel.
