Description

[0044] A preferred embodiment of the invention will now be described, by way of a non-limiting example, with reference to the accompanying drawings in which:

[0045] FIG. 1 shows a mobile waste segregation system according to an embodiment of the invention; and

[0046] FIG. 2 illustrates a segregation of waste into multiple streams of product or commodity.

[0047] The figures are not necessarily to scale, and certain features and certain views of the figures may be shown exaggerated in scale or in schematic form in the interests of clarity and conciseness.

[0048] A mobile waste segregation system according to an embodiment of the invention is shown in FIG. 1. The mobile waste segregation system includes an enclosure unit 10 that is in the form of a cargo container that can be loaded onto a back of a lorry or other vehicle.

[0049] This enables the mobile waste segregation system to be transported between different sites.

[0050] The enclosure unit 10 is sized so that one or more human operators 12 can work freely inside the enclosure unit 10. The enclosure unit 10 houses a personnel identification device, a waste segregation facility 14, an RFID reader, a cleaning device, a plurality of storage containers, a plurality of waste processing devices 16, a packing facility, a weighing scale, an RFID tagging device and a storage facility. The enclosure unit 10 additionally includes a fire alarm system, a closed-circuit television camera system and an air ventilation system 18. In addition to the enclosure unit 10, the mobile waste segregation system includes a lifting apparatus.

[0051] Use of the mobile waste segregation system to carry out a waste segregation process is described as follows with reference to FIGS. 1 and 2.

[0052] Initially the mobile waste segregation system is transported to a new site. For the sake of illustrating how the invention works, the invention is described with reference to a train station as the new site, but it will be appreciated that the invention is applicable to other types of waste-producing sites, non-limiting examples of which are described elsewhere in this specification.

[0053] After the mobile waste segregation system is parked at the new site, a human operator (referred to hereon as a waste warden 12) is required to complete a pre-operational safety audit before carrying out the waste segregation process. The waste warden 12 stands in front of the personnel identification device, which includes a camera linked to a computer having a processor and a memory programmed with facial recognition software. Once the facial recognition software identifies the waste warden 12, the computer will walk the waste warden 12 through a series of questions and checks to carry out an assessment, which includes checking the physical and mental well-being of the waste warden 12, the waste warden's understanding of the risks and procedures of the waste segregation process and the waste warden's certification and equipment requirements.

[0054] After the waste warden 12 passes the assessment, the waste warden 12 initiates the waste segregation process. Preferably the waste segregation facility 14 includes printed guidance in the form of text and/or graphics that explains the waste segregation process.

[0055] Waste bags from various sources (e.g. retailers, platform bins, office bins) may be stored at the locations of the sources or stored at a central facility in the train station. The waste bags are moved from the source or the central facility to the mobile waste segregation system. Each waste bag is received by the waste warden 12 through an entrance 20 (e.g. window or door) of the enclosure unit 10 and placed onto the waste segregation facility 14 (such as a table, desk or workbench) next to the window. In case of heavy or bulky waste bags, the lifting apparatus is operated to lift the waste bags through the entrance 20. Alternatively another person outside the enclosure unit 10 may pass the waste bags to the waste warden 12 through the entrance 20.

[0056] The waste warden 12 uses a RFID scanner to read an RFID tag attached to a given waste bag. The RFID tag includes information about the waste bag, such as the source of the waste, the type of waste and the quantity of the waste. The read information is then recorded as waste data that is then stored on the computer and/or in a cloud-based computing network. The stored waste data may also include the time, date and location of the collection of the waste bags, which may be automatically generated or manually inputted. It will be appreciated that the RFID tag of each waste bag may be read outside the enclosure unit 10 and prior to the waste bags being received through the entrance 20 of the enclosure unit 10, e.g. when the waste bags are collected from the various sources or the central facility.

[0057] The waste warden 12 then opens a waste bag, using a cutter if necessary. Once the waste bag is opened, a visual check for any sharp or harmful objects is conducted. Any sharp or harmful object is removed and placed in a dedicated hazardous waste container. For safety purposes, the waste warden 12 is equipped with waste segregation hand-operated tools (e.g. a picker and tongs) and body protective clothing (e.g. goggles, gloves and aprons).

[0058] After removing the sharp or harmful objects, the waste warden 12 manually segregates the remaining waste from the waste bag into different streams of product or commodity, as exemplarily illustrated by FIG. 2. Non-limiting examples of products and commodities include low grade plastics, high grade plastics, metals, paper, cardboard, coffee cups, glass, hazardous waste, waste electrical and electronic equipment (WEEE), aerosols, coffee granules, cooking oils and food. The sharp or harmful objects may be classed under the stream of hazardous waste. During the manual segregation, the different streams of product or commodity are stored in respective storage containers so as to physically separate the different streams to avoid cross-contamination.

[0059] The cleaning device may take the form of a hose or showerhead connected to a water tap that, if necessary, can be used to wash and/or decontaminate one or more of the streams of product or commodity. A cleaning fluid, such as detergent, may also be used. The cleaning device may also be used to wash down the waste segregation facility 14 so that it is in good order for the next waste segregation process.

[0060] The plurality of waste processing devices 16 includes a compactor, a baler and a crusher for on-site processing one or more of the streams of product or commodity. The compactor is operated to compact a selected stream of product or commodity to reduce its size. The baler is operated to form the selected stream of product or commodity into a bale of a specific size and shape. The crusher is used to crush a selected stream of product or commodity, such as glass.

[0061] Where applicable, suitable segregated streams of product or commodity in the storage containers are emptied into corresponding compactors, balers and crushers, as necessary. Preferably the waste processing involves at least forming bales out of the segregated streams of product or commodity. Each bale may be packed and secured using a fastener, such as a rope tie and prong.

[0062] The bale is removed from the baler and placed onto a pallet 22 at which point the bale is weighed using the weighing scale and then electronically tagged with an RFID tag using the RFID tagging device. Preferably each bale is prepared to have a predetermined weight. The information in the RFID tag includes the type of product or commodity, time and date stamps, the weight of the product or commodity, the end destination of the product or commodity and optionally waste transfer documentation.

[0063] At this point each bale is now ready for transportation and is moved to a storage facility. Each bale may be packed inside a packing container, such as a bag, a bin, a package or a box. For example, a given bale may be securely locked down with a sealed plastic lid. The plastic sealed lid is a lightweight plastic “freight lid” and will cover the bale and the entire pallet so that no weathering or any pest can get underneath the pallet and into the waste. Optionally an RFID tag with the information about the bale may be added to each packing container, or an existing RFID tag of each packing container may be updated to include the information about the bale.

[0064] It will be appreciated that one or more packed streams of product or commodity, such as coffee granules, cooking oils and food, will have to be packed inside respective packing containers to which an RFID tag may be added or for which an existing RFID tag may be updated.

[0065] When the waste collector arrives to pick up the packed streams of product or commodity, they may optionally retrieve the waste transfer document from each RFID tag. The packed streams of product or commodity are then collected and transported to their respective end destinations for further usage or processing into usable products or commodities. In this way, each segregated stream of product or commodity is recyclable, diverting any need for the incineration to landfill procedure. It will be appreciated that different packed streams of product or commodity may be transported to different end destinations or the same end destination, multiple waste collectors may pick up different packed streams of product or commodity and/or one or more streams of product or commodity may be left on-site for further usage or processing into usable products or commodities.

[0066] The processing of the segregated streams of product or commodity, as necessary, into clean and tidy bales and packing containers with specific dimensions and weight not only makes it easier for the waste to be collected and handled by the waste collector but also enables the waste collectors to be cost and energy efficient by coming to collect the bales only when needed, thus saving time, energy, fuel and associated carbon credits that have air pollution reduction benefits.

[0067] The features of the mobile waste segregation system of the invention therefore enable the waste warden 12 to carry out the waste segregation process inside a safe, clean and contained environment that is smaller in size and footprint than a standard waste compactor used in conventional waste processing for recycling. Meanwhile the integration of asset tracking procedures into the waste segregation process together with the information in the asset tags of the waste bags and the packed bales enable the tracking of waste-related information to generate accurate quantitative and qualitative waste data.

[0068] The waste data can be used to improve the waste management systems of the train station to provide cost savings and improve compliance with environmental regulations. For example, the waste management systems may be enhanced by: [0069] optimising the frequency of waste collection using the time, date and location information and the type and amount of waste generated by the train station; [0070] tracking waste bag usage, such as identifying whether the waste bags are underutilised or overutilised, in order to optimise individual waste bag usage and optimise the number of waste bags required by each source; [0071] tracking waste-producing behaviour of the site and each source, including breakdown by waste type and amount and by time and date; [0072] tracking historical waste generation, contamination levels, recycling rates, recycling quality, carbon footprint and pollution figures.

[0073] The waste data can be presented immediately and/or via a regular schedule. For example, the waste data can be compiled and presented in real-time using an online dashboard system and/or can be communicated to the waste-producers at a later time, preferably at regular intervals, using e-mails, text messaging, mobile apps or other forms of electronic communication.

[0074] It is envisaged that, in other embodiments of the invention, the RFID tag, reader and tagging device may be replaced by other types of asset tags, asset readers and asset tagging devices, such as a barcode tag, a barcode reader and a barcode tagging device. The barcode tag may be a barcode label. The barcode tagging device may be configured to produce barcode labels.

[0075] It is envisaged that, in other embodiments of the invention, the function of the computer may be implemented by one or more of an electronic device, a portable electronic device, a portable telecommunications device, a mobile phone, a personal digital assistant, a tablet, a phablet, a desktop computer, a laptop computer, a server, a cloud computing network, a smartphone, a smartwatch, smart eyewear, and a module for one or more of the same.

[0076] It is envisaged that, in other embodiments of the invention, the camera may be replaced by a different type of image capture device.

[0077] It is envisaged that, in still other embodiments of the invention, information about the product or commodity may be inputted into the input module by using a keyboard, using a computer mouse, using a virtual keyboard on a touchscreen and/or choosing from a range of preset answers displayed on the touchscreen. Alternatively or additionally, the input module may be configured to read text, for example, by computer vision and/or optical character recognition.

[0078] It will be appreciated that references to a memory or a processor may encompass a plurality of memories or processors.

[0079] Preferences and options for a given aspect, feature or parameter of the invention should, unless the context indicates otherwise, be regarded as having been disclosed in combination with any and all preferences and options for all other aspects, features and parameters of the invention.
