A process for deactivating Ziegler-Natta or metallocene transition metal catalysts or catalyst systems. The process includes heating the active catalyst or catalyst system to a temperature sufficient to drive off volatile constituents, and to form complexes and compounds that are non-reactive or less reactive with ambient air than the active catalyst or catalyst system. The process includes steps for safe deactivation including scrubbing to substantially eliminate corrosive compounds, and burning volatile chemicals in a flare. This process essentially substantially eliminates the production of hazardous classification waste from conventional water catalyst deactivation techniques.
