Abstract
The invention discloses differing embodiments of trash management systems and methods for the disposal and/or collection of trash. In one embodiment under the invention, a trash management system may include a mobile cart, a trash vessel connected to the cart, a piston adapted to compact trash within the trash vessel, and a passageway adapted to be connected to a vacuum trash disposal. The piston may be adapted to travel from one position to a second position, and back from the second position to the first position. This movement of the piston may be achieved utilizing multiple passageways which are each adapted to be connected to a vacuum source and a vent source.
