<p>Utilization of oil-contaminated wastes, especially drilling mud and drilling wastes, to produce earth with natural soil functions in controlled, aerobic earth-forming processes involves treating the wastes with physicochemically-reactive, mineral, organic, biochemical or microbiologically active mix components or additives, which analyzed by fractional extraction prior to the mixing to give the required product. Utilization of oil-contaminated wastes, especially drilling mud and drilling wastes, to produce earth with natural soil functions in controlled, aerobic earth-forming processes involves treating the wastes with physicochemically-reactive, mineral, organic, biochemical or microbiologically active mix components or additives, such as sands, sandy loams, excavated soil, gravel washing sludges, rubble, dredged slurry, sawdust, bark wastes, crop residues, green cuttings, natural or industrial biomass residues, communal clear sludges, sieved refuse, compost products, biogas recovery residues, pulp sludges, shredded timber or regulators such as sulfates, carbonates, nitrates or silicates. The additives are analyzed by fractional extraction prior to the mixing with the waste, to determine the required ion concentrations and soluble phase combinations as well as the bioavailability of nitrogen and carbon. The amounts determined are then added to the waste to give the required soil properties together with decomposition of the hydrocarbon components, such that the final product can be used like natural soil.</p> |
