  • Patent number: 5578110
    Abstract: A method by which numerous gas generators from unused air-bags can be scrapped in an environmentally acceptable manner. The method consists ofa) heating the gas generator to actuate the generator to produce combustion gases and an actuated generator having water soluble contaminants thereon;b) washing the actuated generator with a water composition to remove the contaminants from the actuated generator to produce a washed generator and a contaminated water composition containing the contaminants;c) dividing the washed generator to produce divided generator parts;d) chemically treating the contaminated water composition to produce a purified water composition; ande) classifying the divided generator parts into classified generator parts.Optionally, the dividing step can occur before the washing step, or before and after the washing step.
