Recent field experiences show that landfills accepting both raw municipal solid waste(RMSW) and incinerated RMSW (highly alkaline) can undergo a highly exothermicamphoteric reaction of aluminum metal and alkaline water by the following reaction: Al (metal) +  (OH)-1(AQ)  +  3 H2O(L)  =   [Al(OH-1)4]-1(AQ)  +  3/2 H2 (Gas). This and other reactions can result in the emission of noxiousfumes and damage to the engineered components of the landfill. This paper will investigatemethods for the beneficial use of aluminum wastes instead of landfilling and how to benefit if a landfill is unfortunately impacted by an aluminum reaction such as �mining� the thermalenergy produced using a Stirling type turbine to produce electricity, capturingthe hydrogen gas for use as a fuel, and excavating the aluminum waste and using it as a fuel source.
