Emirates Global Aluminium (EGA) announced the commissioning of the waste management system for its Al Taweelah alumina refinery, which is under construction. The milestone comes as EGA prepares to begin production at Al Taweelah alumina refinery during the first half of 2019, said the company.
Bauxite residue is a by-product of alumina refining, and EGA’s goal is to responsibly manage its storage and develop potential re-uses, says the company which has completed construction of a dedicated storage area for bauxite residue about 30 kilometres from Al Taweelah alumina refinery in Khalifa Industrial Zone Abu Dhabi.
When Al Taweelah alumina refinery starts production, bauxite residue will be washed, pressed into a dry cake, and transported to the area for permanent managed storage using a fleet of sealed trucks. The storage site will be progressively sealed and landscaped, with the land re-used for potential projects from warehousing to a solar farm, as per the press statement. EGA has signed a contract with waste management company Veolia to manage the transport of bauxite residue and the storage facility.
“The responsible management of bauxite residue has been a key priority for Al Taweelah alumina refinery since the project was on the drawing board, and UAE environmental regulators rightly set tough standards. I am confident that we have a world-class storage solution in place, but our ambitions are much higher as we aim in the longer term to turn this waste into value through innovation,” commented Zaher Al Habtari, Senior Vice President of Refinery Operations, EGA.
EGA is working with the American University of Sharjah, The University of Queensland and other universities, as well as expert consultancies, to research and develop economic uses for bauxite residue which, if successful, would be a global breakthrough for the aluminium industry, said the company.
