In method for freeze-crushing waste resources, freezing gas is first created
by
collecting freezing heat source of liquefied petroleum gas during a heat exchange
process between the liquefied petroleum gas and cooling gas, and then the waste
resources stored in a freezing tank is frozen to a temperature where the waste
resources can be easily crushed by supplying the freezing gas to the freezing tank.
Next, the frozen waste resources is crushed in an crushing apparatus, after which
the freezing gas is separated from the crushed waste resources in a separate apparatus
and the freezing gas for is collected the purpose of reuse.
