<P>PROBLEM TO BE SOLVED: To provide a method for using a waste material of a lightweight structural material without costing much. Ž<P>SOLUTION: The method for using the waste material of a lightweight alloy includes: using ingots or fragments of a lightweight alloy waste which is primarily used as a lightweight structure material; putting the ingots or fragments in a high pressure container 2; breaking the oxide film on the surface by laser under hydrogen pressure to bring the alloy surface into contact with hydrogen; performing hydrogen occlusion by hydrogenation reaction to produce pulverized hydride particles; and thereafter, either packing a filter-type bag with the hydride particles or pressure-bonding the hydride particles or solidifying the hydride particles with a binder to use the particles as a functional material for metal reaction (hydrolysis) or ionization reaction (electrode active material) for secondary use in a siphon type or battery type hydrogen generation apparatus. After that, the remaining hydroxides are recovered for the third use. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
