Abstract

A method for disposing of propellant containers containing a propellant, comprising submerging the propellant containers in a detonation suppressant liquid, shredding the propellant containers while submerged in the detonation suppressant liquid into shredded propellant container material reduced in size to provide release of the propellant from the propellant containers, and removing the shredded propellant container material from the detonation suppressant liquid. A system for disposing of propellant containers is also disclosed.

Claims

1. A method for disposing of propellant containers containing a propellant, comprising:

submerging the propellant containers in a detonation suppressant liquid;

shredding the propellant containers while submerged in the detonation suppressant liquid into shredded propellant container material reduced in size to provide release of the propellant from the propellant containers; and

removing the shredded propellant container material from the detonation suppressant liquid.

2. The method of claim 1 in which the propellant containers are inflation components of airbag systems.

3. The method of claim 2 in which the detonation suppressant liquid is water.

4. A system for disposing of propellant containers containing a propellant, comprising:

a chamber containing a detonation suppressant liquid, said chamber including an inlet for receiving propellant containers and an opening for discharging shredded propellant containers;

a shredder including shredder components received within said chamber and submerged in the detonation suppressant liquid;

an inlet conveyor configured to deliver propellant containers into the inlet of said chamber; and

a discharge conveyor configured to deliver shredded propellant container material away from said chamber, the shredded propellant container material being of a size to provide release of the propellant from the propellant container material.

5. The system of claim 4 and further including a low level sensor for detecting a minimum predetermined level of the detonation suppressant liquid in said chamber, and a high level sensor detecting a maximum predetermined level of the detonation suppressant liquid in said chamber.

6. The system of claim 5 and further including a controller for maintaining the level of detonation suppressant liquid in said chamber between the minimum level and the maximum level.
