Aluminium waste is the residual waste material is produced from refining aluminium, also know as aluminium dross. This dross mainly consists of metals fragments, salts, metal oxides.
Rainfall percolating into the waste reacts with the anhydrous aluminium compounds generating ammonia, acetylene, hydrogen and other unusual nuisance gases. The reactions are strongly exothermic, so waste temperatures are very high. The maximum temperature recorded at the site within the waste is 83°C, with surface temperatures typically around 35°C.
Capping Scheme to limit infiltration Offered the greatest benefit of the available funding
High temperature of the waste Clay - dehydration and shrinkage Plastics - performance of the polymer at elevated temperature was unknown Gas collection - Visual Modflow Excavation Difficulty
It is backed by the UK Government and industry, the new treatment method makes it economically viable to treat residual waste left after conventional recycling, offering cost savings and environmental benefits.
