A waste compaction apparatus may include a housing and a connector arm. The housing may define a drive chamber and a compaction chamber and the connector arm may include a drive piston portion movably positioned within the drive chamber and a compaction piston portion movably positioned within the compaction chamber. The drive chamber may be selectively fluidly coupleable to the near-vacuum of outer space, such that the compaction piston portion of the connector arm is configured to move within the compaction chamber to compact waste material contained within the compaction chamber in response to movement of the drive piston portion of the connector arm within the drive chamber.

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.

An extension for connection to a vehicle can include a first side, a second side, a ceiling, and a bottom, the first side opposing the second side and the ceiling opposing the bottom, each of the first side and second side connected to the ceiling and the bottom; a partition arranged between the first side and the second side; and a baler, wherein the ceiling, the first side, the bottom, and the partition define a storage compartment, wherein the ceiling, the second side, the bottom, and the partition define a baler compartment, and wherein the baler is arranged within the baler compartment, the baler comprising a compression system and a baling system.

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.

A waste compaction apparatus may include a housing and a connector arm. The housing may define a drive chamber and a compaction chamber and the connector arm may include a drive piston portion movably positioned within the drive chamber and a compaction piston portion movably positioned within the compaction chamber. The drive chamber may be selectively fluidly coupleable to the near-vacuum of outer space, such that the compaction piston portion of the connector arm is configured to move within the compaction chamber to compact waste material contained within the compaction chamber in response to movement of the drive piston portion of the connector arm within the drive chamber.

A hydraulic accumulator including an energy storage apparatus with a first piston face configured to reversibly compress an energy storage medium and a second piston face forming at least part of an inner surface of a corresponding second fluid chamber reversibly expandable by movement of the second piston face. A third piston face forms at least part of an inner surface of a corresponding third fluid chamber reversibly expandable by the third piston face. The first, second and third piston faces are coupled together.

Method for handling waste material in a pneumatic pipe transport system, wherein waste material is fed in from an input point into conveying piping, and conveyed in the conveying piping, mainly by the aid of suction/a pressure difference and/or a flow of transporting air, onwards to a separating device (1), in which the waste material to be transported and the transporting air separate from each other, from which separating device the waste material is transferred onwards to a separate waste container (26). Waste material is transferred, or is transferred and compressed to become denser, from the separating device (1) into a separate waste container (26) in a connecting channel (9) arranged between them with a transfer member (10) from the input aperture (8) of the connecting channel towards the output aperture (9′) and onwards into a separate waste container (26), and in which method the connection from the separating device (1) to the connecting channel (9) is closed at least during the detachment of the waste container (26). The invention also relates to an apparatus.

A trash compacting apparatus comprising a container, an air pump, one or more inflatable air bladders, a controller unit, and an interface unit is disclosed herein. The apparatus may further comprise an air distributor. The apparatus may operate as a standard trash container and may further comprise a lid. The apparatus may be operated by the user or by a programmable controller unit to inflate the air bladders, thereby compressing trash contained within the apparatus and reducing the total volume of the trash.

An apparatus for processing material in connection with a pneumatic material conveying system includes a waste container/separating device, into which material is configured to be conducted from a conveying pipe of the pneumatic material conveying system via an inlet aperture and which is configured to be connected to a partial vacuum generator. The apparatus further includes a press device/compactor device, which is arranged to act on the material (w) conducted into the waste container/separating device, via at least one aperture formed in the container, and that at least one wall that is transverse with respect to the input direction of the material is arranged in the container space of the waste container/separating device, which wall is configured to guide the material into the operating range in the container space of the compressor of the press device/compactor device.

An automatic can crusher apparatus for crushing cans for recycling includes a housing having a ram aperture extending through to a housing inside. A ram has a pneumatic cylinder body, a ram arm extending through the ram aperture, and a ram head coupled to the ram arm. The ram moves the ram head between a load position and a crush position adjacent a housing right side. A can positioner is coupled to a housing left side within the housing inside to secure a can adjacent the ram head in the load position. A feeder chute is coupled to the housing top side to receive a plurality of cans through a chute top end and dispense each can through a chute bottom end onto the can positioner when the ram head is in the load position.
