Abstract: A trash compactor having a compactor unit and a separable trash storage container is provided that accommodates liquid within the trash that is compacted. The liquid is admitted into a reservoir within the storage container of the trash compactor where it is isolated from the compacted trash. When the storage container is removed to a disposal site, the compacted trash is emptied and the liquid from the reservoir is also emptied at the disposal site. For trash that has a large volumetric quantity of liquid, an overflow tank may be provided in the storage container to receive the overflow from the reservoir within the storage container. The overflow tank may also receive liquid that accumulates in the compactor unit while the compactor is operating.
