An automated trash management system for measuring the fullness of a plurality of trash containers, each trash container associated with a packing system having a compression member for engaging and compacting the trash in the container and, optionally having a limit switch activated by the compression member when the compression member is fully extended for controlling the movement of the compression member by the packing system. The automated trash management system comprises a plurality of remote status units each in association with a trash container comprising a sensing device for monitoring the pressure provided to the compression member by the compacting system and means for determining the fullness of the trash container based upon the monotonic increase in pressure associated with the compression member engaging and compacting the trash in a container, a central unit for receiving the container fullness calculations from each remote status unit and for compiling a data base of the fullness of each trash container and a communications linkage for transferring the fullness calculations from said plurality of remote status units to the central units such that the fullness of each trash container can be monitored at the single location of the central unit, and from the same single location, authorization to a hauler to empty the trash containers can be restricted to only those containers which are approaching full thereby reducing the frequency of and the expense of hauling.

Apparatus for measuring the level of fullness of a trash compactor having a compression member for packing the trash, the trash compactor including a hydraulic pressure line carrying hydraulic fluid under pressure to energize said compression member during compaction strokes of trash in the trash compactor, and a limit switch for generating a limit switch signal when said compression member has reached its maximum compaction travel during each cycle of said compression member, the apparatus comprising, means connected to said hydraulic pressure line for generating a pressure signal indicative of the hydraulic pressure driving said compression member during each compression cycle, means responsive to said limit switch signal and to said pressure signal for generating a current maximum pressure signal during each compaction cycle when said compression member has reached its maximum compaction travel, means responsive to said limit switch signal for counting the compaction cycles, means for modifying said current maximum pressure signal during any compression cycle so that it cannot increase from the value to be reported more than a predetermined pressure amount, and means for storing said modified pressure signal as a function of the number of compaction cycles, wherein said modified pressure signal as a function of the number of compaction cycles is indicative of the level of fullness of said trash compactor.
