Abstract
Waste material containing substantial amounts of Li(MH.sub.3 R) compounds where M is Al or Ga are deactivated by dissolving and/or dispersing the waste material in a solvent in which ionic deactivation products are soluble and then adding a carbonyl-containing compound which reacts with the Li(MH.sub.3 R) compound.
