A process is described for disposing of earth contaminated with petroleum products from a leaking underground storage tank wherein the earth contains a significant amount of material comprised primarily of a mixture of one part Al[sub 2]O[sub 3] and two to three parts SiO[sub 2], the process comprising: digging up a leaking underground storage tank and the surrounding contaminated earth; separating the excavated earth into a Al[sub 2]O[sub 3]+SiO[sub 2] material and a non-Al[sub 2]O[sub 3] + SiO[sub 2] material; mixing the Al[sub 2]O[sub 3] + SiO[sub 2] material and other cement precursor raw materials together to form a mixture, and grinding the mixture to form a feed mix; introducing the feed mix into a rotary cement kiln causing any remaining petroleum product contained therein to be volatilized and burned within the kiln as cement clinker is being produced; and grinding the cement clinker together to form cement which is free of petroleum product.
