3.  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.

4.  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.

5.  Capping Scheme to limit infiltration  Offered the greatest benefit of the available funding

7.  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

8.  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.
