1. A unit for treating hydrocarbon contaminated soil and sludge waste material using exothermic stabilization processes, the unit comprising:

  • a weigh batch hopper divided into a first bin for holding waste material and a second bin for holding reagent so that the waste material and reagent can be dispensed simultaneously or sequentially;

    breaking means for receiving waste material and reducing solids in the waste material to a maximum dimension of four inches;

    first conveying means for transferring the waste material from the breaking means to the first bin of the weigh batch hopper;

    reagent storage tanks for storing reagent;

    second conveying means for transferring the reagent from the reagent storage tanks to the second bin of the weigh batch hopper;

    mixing means for receiving batches of the waste material and the reagent from the weigh batch hopper and for mixing water, the waste material and the reagent together;

    a walking floor conveyor for receiving and transferring a mixture of the waste material and the reagent discharged from the mixing means without further mixing and holding the batches a sufficient time for a reaction between the reagent and the waste material to be completed; and

    third conveying means for transferring the mixture received from the third conveying means to a stockpile for processed material.
