Method and apparatus for treatment of oilfield wastes, so that the wastes may be disposed of without harm to the environment or may be recovered as valuable products, wherein the wastes are pretreated to enhance separation of solid materials, the solid materials being dried and incinerated to a char solids condition, the char solids and the heating gases being cooled by heat exchange to provide hot air for combustion in the dryer-incinerator, thereby saving heating fuel cost, the gases being scrubbed to remove contaminants, and the condensed water-hydrocarbon phases being separated for reuse or for further treatment for recovery.
