Abstract: 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.
