Embodiments of the present disclosure are directed to new and improved self-contained compactor systems incorporating a straight-push cylinder design, in which the compactor system is actuated in a horizontal direction. The improved design accommodates increased storage volume, long wear parts, simplified reservoir cleaning, and easier external access to the components, cylinders, and hoses of the self-contained compactor system.

A compactor trolley for aeronautical applications, more particularly a trolley, includes a flap for direct access to the waste storage compartment and a safety locking mechanism for the flap.

A compactor (1) for waste material comprises a housing (3) for receipt of a bag (4), the housing comprising sidewalls (11, 12) including at least one openable sidewall (13), and a compacting press comprising an actuator to force material into the bag when it is housed in the housing. At least one of the sidewalls comprises two adjacent panels (14, 15) connected by articulation means (16) allowing the sidewall to fold during a compaction operation. The folding of the sidewall has been found to dissipate the stresses caused by the pressure in the bag/housing due to the changing geometry and the movement of waste material into regions of lower density or voids created by the changed geometry.

An example lavatory waste compartment includes a waste bin having a waste compartment for trash, a waste flap providing an opening into the waste compartment for insertion of the trash, and a manually operated trash compactor coupled to a ceiling. The manually operated trash compactor includes an expansion component connected to a compacting head, and a retraction component coupled to the expansion component to hold or retract the expansion component to a stowed position. An increase in temperature above a threshold temperature causes the retraction component to release the expansion component resulting in deployment of the compacting head into the waste bin. An actuation device is provided to deploy the expansion component from the stowed position, and when deployed, the expansion component blocks opening of the waste flap, and the retraction component causes the expansion component to retract to the stowed position via release of the actuation device.

An unloading system comprises an upper-opening chamber for receiving airplane-derived refuse, a chute, a chute-connected safety gate which is settable in falling preventing relation with respect to an access door of an airplane from which the refuse is unloadable into the chute and to the chamber, and an air brake assembly for immobilizing the safety gate when the chute ceases to be vertically displaced.

A trolley for collecting waste includes: wheels, a steering handle, and a housing with a bottomwall and a sidewall extending vertically from the bottomwall, wherein the housing forms a waste chamber, wherein the sidewall comprises an opening, wherein a flap is connected by a first bearing to the sidewall of the housing, such that the flap is pivotable about a horizontal flap axis between a closing position and an opening position. The flap in its closing position closes the opening of the sidewall, and the flap in its opening position opens the opening in the sidewall, wherein the handle is connected by a second bearing to the housing, such that the handle is pivotable about a handle axis between a first handle position and a second handle position, and the handle is linked to the flap by a mechanical linkage, such that pivoting the handle from its second handle position to its first handle position results in a pivoting of the flap from its opening position to its closing position.

A recycling method includes the steps of compacting recyclable material into a fixed bale, and weighing the recyclable material, using load cells, independently of the compacting forces. Compacting equipment for performing the method includes balers with load cells and anchors, with the load cells weighing the baler and the recyclable material in the baler, and with the anchors anchoring the baler in place without interfering with the weighing.

A compactor system for compacting waste having liquid components. The compactor system includes a storage container having a storage chamber and a dump door. A charge container includes a compacting chamber and a loading opening. An outlet fitting is mounted to the charge container. The outlet fitting is in fluid communication with the compacting chamber. A pump is in fluid communication with the outlet fitting. A storage tank is in fluid communication with the pump. The storage tank, storage container and charge container are positioned on a support surface. The pump pumps fluid from the compacting chamber into the storage tank.

Apparatuses for forming blocks of compactable material such as snow, having a hollow upper body with a compression chamber within for containing and subsequently compressing the compactable material to form a block that can be used in connection with recreational activities. A lower body having a flat compression plate attached to a top end, is configured to slide within the compression chamber, the compression plate being capable of pushing the compactable material into a hinged lid that is attached to a top end of the upper body and acts to cover a top opening of the upper body. Ferromagnetic materials attached to the underside of the compression plate are configured to contact other ferromagnetic materials attached to the interior walls of the compression chamber, which at least temporarily arrests sliding movement of the upper and lower bodies, and allows a user to fill the apparatus with compactable material.

An unloading system comprises an upper-opening chamber for receiving airplane-derived refuse; a chute; a chute-connected safety gate which is settable in falling preventing relation with respect to an access door of an airplane from which the refuse is unloadable into the chute and to the chamber; and an air brake assembly for immobilizing the safety gate when the chute ceases to be vertically displaced. A compacting system comprises a main platen mount with an occluding surface for occluding the opening; an auxiliary platen mount for movably supporting the main platen mount; a holder assembly underneath the auxiliary platen mount; and force transmitting elements always retained within a compaction chamber interior. The main platen mount is linearly driven between a first position completely forwardly of the opening and a second position at which the opening is completely occluded, and is additionally driven to discharge the received refuse. Methods are also disclosed.
