a pull cable connected to the support rod,
wherein based upon manual operation of the pull cable, the support rod is pulled linearly causing deployment of the expansion component.
14. The waste compartment of claim 13 , wherein the pivotal joint assembly and the eutectic alloy fusible link are positioned substantially adjacent to the pull cable in the waste compartment.
15. The waste compartment of claim 11 , wherein the system comprises:

wherein based on manual retraction of the support rod, the gas strut compresses and is operated to deploy the compacting head of the trash compactor to compact contents of the waste compartment, and
wherein based on collapse of the pivotal joint assembly, the pivotal joint assembly pulls the gas strut in the extended configuration causing retraction of the support rod to deploy the compacting head of the trash compactor to compact contents of the waste compartment.
17. A method for deployment of a compacting head in a waste compartment, comprising:
