Emirates Global Aluminium, the largest aluminium producer in the United Arab Emirates signed an agreement with Gulf Cement Company to supply 27,000 tonnes of spent pot lining, a by-product from aluminium smelting. The waste material will be supplied over next three years for use in cement manufacturing.

EGA has been supplying spent pot lining to the cement industry through third parties since 2010. However, this is the first time such an agreement is signed between EGA and a cement company outside its circle. EGA is building facilities at its Al Taweelah site to process spent pot lining so that it can be delivered ready to be used by cement companies as an alternative fuel and raw material.
Abdulla Kalban, Managing Director and Chief Executive Officer of EGA, said: “This direct agreement with Gulf Cement Company is a milestone in our drive to turn our by-products into value by using them as feedstock for other industries...”
Sheikh Kayed Bin Omar Bin Saqr Al Qasimi, Chairman of Gulf Cement Company also expressed his pleasure in promoting the utilisation of waste materials in order to preserve natural resources and protect the environment.
Spent pot lining is the used inner lining of aluminium smelting pots, which is worn out and replaced every four to five years. It contains both carbon, which is an alternative fuel, and refractory materials that survive the firing process and become part of the finished cement.
Last year EGA supplied more spent pot lining to the UAE’s cement industry than it produced. EGA has been supplying Gulf Cement Company with spent pot lining via third parties for testing since 2015.
Globally, the aluminium industry produces more than one million tonnes of spent pot lining each year according to industry experts, and much is stored indefinitely. EGA will be gradually supplying the spent pot lining from previous years to the cement industry.
Under the new agreement, EGA will deliver 2,000 tonnes of spent pot lining in 2018 and the volume will increase to 10,000 tonnes in 2019, followed by 15,000 metric tonnes in 2020.
Gulf Cement Company has been the biggest exporter in the Gulf region for four decades, in part by adopting best practice in the protection of the environment and operates the world’s biggest waste heat recovery-based power plant at a single site.
