Abstract: A composition for use as fertilizer includes cement kiln dust and animal manure. The content of cement kiln dust and animal manure in the composition is selected as a function of either weight or volume. The content of cement kiln dust is greater than or equal to the content of animal manure. The fertilizer composition is formed by mixing the cement kiln dust and animal manure at ambient temperature and pressure.

Abstract: A method of treatment of aqueous liquid contaminated by pollutants, includes (i) mixing the contaminated aqueous liquid with a mineral binder in order to produce an homogeneous slurry, (ii) depositing the slurry, (iii) letting the slurry set and harden, wherein the mineral binder includes Portland cement, and wherein the contaminated aqueous liquid includes organic pollutants.

Abstract: Process for disposing of clay, shale or sand containing earth contaminated with petroleum products from a variety of remediation sites is disclosed. The surrounding contaminated earth to be remediated is first excavated. Then, any clay or shale which is present is separated from the other materials and transported to a site of a cement plant. The non-clay or non-shale material is disposed of in a non-hazardous landfill. At the cement plant, the clay or shale is mixed with other cement precursor raw materials and the mixture is ground to form a cement feed mix. The feed mix is introduced into a rotary cement kiln causing any remaining petroleum product contained therein to be volatilized and burned within the kiln as the cement clinker is formed. The clinker is then ground for the purpose of forming cement free of petroleum product.

Abstract: Process for disposing of clay, shale or sand containing earth contaminated with petroleum products from leaking underground storage tanks (LUST) as disclosed. The LUST and surrounding contaminated earth is excavated. The clay or shale is separated from the other materials and transported to a site of a cement plant. The non-clay or non-shale material is disposed of in a non-hazardous landfill. The clay or shale is mixed with other cement precursor raw materials and the mixture is ground to form a cement feed mix.
