A method for feeding in and transporting material in a pneumatic conveying system includes at least one input point, a material conveying pipe, and a material container. A partial-vacuum source produces a partial vacuum/a pressure difference and a transporting air current in the conveying pipe. A shut-off element, arranged on an opposite side of an input aperture with respect to a feeder channel, is movable by suction from a first position, in which the shut-off element does not make a pathway through an input aperture into the feeder channel smaller, into a second position, in which the shut-off element does make the pathway through the input aperture into the feeder channel smaller, when the pressure on a first side, on the feeder channel side, of the shut-off element is smaller than on a second side, on an opposite side with respect to the feeder channel, of the shut-off element.

An in-ground apparatus includes a receptacle and a liner into which the receptacle can be placed and removed. The liner may be a molded plastic liner having a tapering body to permit stacking. The lower margin includes a set of seats for anchor fittings in the form of re-bar prongs that, when installed, extend radially outwardly from the liner. The seats, and hence the prongs, are located upwardly of the bottom edge of the liner so that they are embedded above and below when concrete is poured around the bottom of the liner. The bottom edge of the liner is folded upwardly and inwardly to form a V-shaped channel. The seats for the anchor fittings extend across the channel. The seats may include a cylindrical wall sealed from the inside of the liner. The liner may have intermediate stiffening ribs between bottom and top. The top of the liner may have a seat for the receptacle, and an external concrete break.

The present invention describes a subsurface refuse system for side loading collection. It comprises an underground bunker (4), a refuse container (installed with lateral movable arms, a deposit input bin, one internal platform that supports temporarily the container and a cover with automatic opening and closing. All the movements are remotely operated. The container translates and is collected only with an automated side loading lifter installed in the truck.

Movable integrated system for waste collection, including a container structure, adapted to be installed at least partially above ground, the structure including a plurality of access doors to a plurality of waste collection compartments or containers contained in the container structure that are made of two-dimensional modular structure; the container structure integrates a waste compaction unit supplied by a respective access hatch and transferring compacted waste into the collection containers.

A hydraulic compactor configured to be fastened to the cover structure of an underground collection container, for compacting waste materials. The hydraulic compactor includes a filling opening equipped with a hatch, via which the waste material may be entered into a compressing space inside the compactor, a press member being provided above the compressing space and being movable in the vertical direction inside the compactor. The press member presses the waste material fed into the compressing space against the bottom plate of the compactor. The bottom plate of the compactor is a hydraulic bottom plate opening in the horizontal direction, via which the waste material compressed in the compressing space is dropped into the underground collection container. The present disclosure also relates to an underground collection container comprising a compactor.

An in-ground apparatus includes a receptacle and a liner into which the receptacle can be placed and removed. The liner may be a molded plastic liner having a tapering body to permit stacking. The lower margin includes a set of seats for anchor fittings in the form of re-bar prongs that, when installed, extend radially outwardly from the liner. The seats, and hence the prongs, are located upwardly of the bottom edge of the liner so that they are embedded above and below when concrete is poured around the bottom of the liner. The receptacle is formed to contain liquids, such as used cooking oil and hot grease. It has a heating element wrapped around the receptacle, and insulation between the receptacle and the liner. There is an internally concealed pump-out with a swiveling access fitting.

A method is provided for feeding in and transporting material in a pneumatic conveying system for material, which conveying system includes at least one input point of material, a material conveying pipe, which can be connected to the input point, and a material container, in which the material being transported is separated from the transporting air, and also a device configured to product a partial vacuum/a pressure difference and/or a transporting air current in the conveying pipe at least during the transporting of the material, which device includes at least one partial-vacuum source. In the method, the suction side of the partial-vacuum source is connected to act in the conveying pipe and onwards to an input point arranged in the conveying pipe, or to act at least in the feeder channel that is between the conveying pipe and the input point, in which case the input point, or at least the feeder channel, intended for emptying that is closest to the material container in the conveying direction of the material empties and the material displaces into the conveying pipe, that arranged in the input point, on the inside of said input point and on the opposite side of the input aperture with respect to the feeder channel, is a shut-off element, which is moved by means of the suction produced by the partial-vacuum source from a first position, in which the shut-off element does not make the pathway through the input aperture into the feeder channel essentially smaller, into a second position, in which the shut-off element does make the pathway through the input aperture into the feeder channel essentially smaller, when the pressure on the first side, on the feeder channel side, of the shut-off element is smaller than on the second side, on the opposite side with respect to the feeder channel, of the shut-off element. An input point and to a pneumatic material-conveying system are also disclosed.

A refuse collection system having a maximum power point tracker includes a DC-DC converter. The DC-DC converter is electrically connected at a first output thereof to one or more photovoltaic panels of the system, and at second output thereof to one or more batteries for being charged by the photovoltaic panels. The maximum power point tracker is configured to increase the power output of the photovoltaic panels towards, e.g. to set this power output to, the maximum power point thereof, therein adjusting a current at which the batteries are charged. A control unit of the system, programmed to control electrically powered functional parts of the system, is preferably furthermore programmed to control the DC-DC converter.

This invention relates to an underground waste collection system, which has a pedestrian platform that also functions as the lid (1) of a tank (3) into which a container (4) can be inserted and wherein the waste is deposited through a deposition top bin (2), which is external and attacked to the lid (1). The lid opens by means of gas cylinders (7) and, in order that the impact of the opening limit of the lid (1) is as small as possible and does not cause damage to the gas cylinders (7), the lid (1) comprises two brackets, perpendicularly to its axis of rotation, which connect to gas cylinders (7), and wherein at least one of them is a sliding bracket (6).
