Method for feeding in and for handling waste material in the channel section of a pneumatic wastes conveying system, in which method waste material or recycleable material is fed into a feed-in container (10) from the input aperture (2) of at least two input points (1) of a pneumatic pipe transport system for material and onwards into the channel section (20, 21, 22) between the feed-in container and the material conveying pipe (100), from where the material is conveyed along with the transporting air via the material conveying pipe (100) to the delivery end of the pneumatic material conveying system, where the material is separated from the transporting air. In the method the channel section (20(II), 20(III), 20(IV) . . . (22(II), (22(III), 22(IV)) of at least one second input point is connected to the channel section (20(I), 21(I), 22(I)) of one first input point between the input point (1) and an impeding means (30, 30), in that in the method at least a part of the material (w1, w2, w3, w4) fed in is acted upon by the combined effect of suction and replacement air in the channel section (20(I), 21(I), 22(I) . . . (20(IV), 21(IV), 22(IV)) by bringing about compression in size in at least a part of the material (w1, w2, w3, w4) being conveyed, by means of an impediment (30) arranged between the conveying pipe (100) and the material (w1, w2, w3, w4) to be handled, or against the impediment, before transportation of the material to the delivery end of the pneumatic transport system for wastes.

An arrangement for a pneumatic material conveying system comprising a first material conveying system. The arrangement comprises a second material conveying arrangement comprising at least one second input point (200) for feeding a second material (M), a second separator device (10), a second conveying pipe (102) between the at least one second: point (200) and the second separator device (10), which second separator device (10) is operatively connectable into medium communication with a conveying pipe (100) of the first material conveying system along the pipe, in order to connect a suction or a pressure difference acting in the first pipeline (100) to act via the second separator device (10) in the second conveying pipe (201) to convey the second material (M) from the second input point (200) in the second conveying pipe (201) to the second separator device (10) configured to separate the second material (M) from transporting air flow, and to collect the material (M) into a collection container (11) of the second separator device (10).

Methods and system for waste collection and transport systems are provided. Systems of the present disclosure comprise a loading station providing a point of ingress and storage for materials into a larger system. The chute may temporarily house materials. Venting features are provided wherein the chute or load station is provided in fluid communication with an additional component of the system or an exterior environment.

The present disclosure relates generally to the field of waste collection, and particularly to techniques for requesting and controlling access to a waste collection point by using a mobile user device. The mobile user device is initially provided with a user ID that is granted permanent or temporary access rights to one or more hatches of one or more waste containers of the waste collection point. By using the user ID and a user input that comprises an indication of one or more of the waste containers to be accessed in the waste collection point at a given time instant, the mobile user device sends an access request to an access control system. In response to the access request, the access control system unlocks or opens the hatch(es) of the waste container(s) to be accessed, when the mobile user device is in the vicinity of the waste collection point. By so doing, it is possible to provide efficient access management for the waste collection point.

An embodiment of the system for transporting and collecting waste includes a movable receptacle configured to translocate from a first position to a second position and back again, and a vacuum system associated with the movable receptacle. The vacuum system includes a motor for generating suction and a power source connector associated with the motor. The power source connector is associated with the power source and transmits power to the motor when the movable receptacle is in the first position, and the power source connector dissociates with the power source, thereby interrupting power to the motor, when the movable receptacle moves away from the first position. The power source connector includes a connection terminus and a semi-flexible stem that flexes to allow a proper alignment between the connection terminus and the power source when the movable receptacle translocates from the second position to the first position.

Method for conveying and handling waste material in the channel section of a pneumatic wastes conveying system, in which method solid waste material or recycleable material fed into a conveying pipe is conveyed in the conveying pipe of the pneumatic pipe transport system for material along with the transporting air flow to the delivery end of the material conveying system, where the material is separated from the transporting air. In the method the material is acted upon in the conveying pipe by stopping the speed of movement of the material being conveyed in the conveying pipe by means of a stopper arranged between the separating device of the delivery end and the material being handled, or against the stopper at, or in the proximity of, the delivery end of the material conveying system and by bringing about in the channel space of the conveying pipe volumetric compression in at least a part of the material being conveyed by means of the stopper arranged between the separating device of the delivery end and the material being handled, or against the stopper, by means of a pressure difference acting on the different sides of the material being handled, such as by the combined effect of suction and replacement air, before transportation of the material onwards in the conveying pipe into a container of the separating device arranged at the delivery end of the pneumatic transport system for wastes.

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.

Method for compensating a change in volume caused by a pressure difference of the intermediate container of an input point of a pneumatic pipe collection system for material and/or for preventing undesired material displacement from the intermediate container. In the method a bypass channel is arranged in the channel section formed by the intermediate container of an input point for compensating a change in volume resulting from the pressure difference of the pressures of different magnitudes possibly acting on different sides of the material and/or for preventing undesired material displacement from the channel section into the material conveying pipe. The invention also relates to an apparatus and to a wastes conveying system.

A connection piece for pipe connections, which connection piece comprises a tubular envelope having a first end and a second end, which connection piece comprises a channel between the first end and the second end, the channel being delimited by an inner surface of the envelope of the connection piece, which connection piece comprises a first connection area extending to a distance from the first end and a second connection area extending from the second end to a distance, which connection piece has been configured to be bent in a first plane, such as vertical plane, by an angle alpha () which is 0-20 degrees, and/or in a second plane, such as horizontal plane, by an angle beta () which is 0-20 degrees. The invention also relates to a conveying pipe arrangement and to a method.
