A compacting apparatus is described which is operated by pressures derived from a municipal or household supply of water under pressure. The apparatus includes a compression chamber having a feed opening therein for introducing material to be compacted in said chamber. The compression chamber is generally elongated and in one end portion thereof a closeable opening is provided for removal of a slug of compacted material. A moveable cylinder is closely received in the compression chamber, and has one end thereof which operates as a ram for compacting the material therein. The cylinder houses a stationary piston which includes a plate in sealed engagement peripherally of the cylinder to divide that cylinder into two sections. A fluid circuit is connectable in flow communication with each of the sections of the cylinder, and with an external supply of water under pressure. Valve means provided in that fluid circuit are operable selectively to introduce water under pressure into one of the sections for advancing the moveable cylinder, and into the other section for retracting that cylinder. In the preferred embodiment, that section of the cylinder which forms the ram has an area substantially equal to the cross-sectional area interiorly of the compression chamber. In another preferred embodiment, the compression chamber is an elongated cylinder having a closeable opening in one end thereof, and a closure member is provided, pivotally supported from the compression chamber for closing the opening.
