ABSTRACT:
A method for rendering harmless an oily waste material comprising mixing an alkaline earth metal oxide with a surface active agent which delays reaction between the alkaline earth metal oxide and water, combining the mixture with said oily material, and reacting the alkaline earth metal oxide charged with the waste material with approximately the stoichiometric amount of water to convert the alkaline earth metal oxide to the hydroxide. The alkaline earth metal oxide is preferably calcium oxide and advantageously it is also mixed with a hydrophobizing agent prior to mixture with the oily waste material. The proportions are desirably such that the end product is a solid which can be used as a lining in road construction and at dump sites.
