Patent ID: 7413383

Claim:
A process of chemical-biological stabilization for the remediation of soil and cuttings contaminated with oils and derivatives of petroleum, in which the transformation of the organic contaminant into an inoffensive material is achieved, comprising: (a) confining contaminated material selected from the group consisting of soil, sediment, drilling cuttings contaminated with petroleum derivatives, and combinations thereof; (b) mixing said contaminated material with a chemical reagent that contains calcium hydroxide (hydrated lime) in concentrations of between approximately 1 and 10 percent on a dry weight basis of the contaminated material to provide a homogenized mixture; (c) allowing the mixture to rest for a period of time between about 2 hours and about 180 natural days; (d) thereafter adding at least one organic conditioner to the homogenized mixture at a concentration of between approximately 1 and about 15 percent on a dry weight basis of the mixture to provide a conditioned mixture; and (e) curing the conditioned mixture by mineralization and humidification processes during an at-rest period which is between about 15 and about 730 natural days.
