Aluminum smelters have long wrestled with the problem of recycling and disposal of spent pot lining. This hazardous waste stream contains toxic compounds including leachable cyanides & it reacts with water, producing explosive gas mixtures of hydrogen and methane. If land filled it can cause serious environmental damage and a is a major threat to human health. Historic landfill sites have been “cleaned-up” by authorities who have spent hundreds of millions attempting to remediate these toxic time bombs.

Ultromex has invented a unique 2 stage process to treat and fully recycle spent pot liners from the aluminum industry:-
