Method and station for collecting, storing and removing refuse produced by households and in markets

Abstract

The present invention relates to a method and a station for collecting, storing and removing refuse produced by households and in markets. The method comprises collecting waste in durable containers from refuse-depositing points, grouping large volumes (more than 80m3) of waste into storage pits, and removing it using semi-trailer dump-trucks capable of transporting up to 55m3 of waste in a single round. The objectives of installing these waste collection and storage stations are: - To reduce costs relating to the removal of waste produced by households, markets, cities, factories, camps, public housing - To solve the problem of household waste piled up at the roadside in some towns, thereby causing hygiene problems and diseases - To recover recyclable waste (metals, glass, paper, plastics). These objectives are achieved by the creation of the type 1 collection and storage station (see the figure for the abstract). With a storage capacity of 54m3, it is a solution for collecting and storing the waste produced by zones which cover a small area, but which produce a great deal of waste. This is the case with markets, and groups of dwellings (cities, public housing, camps, factories, public housing). This station comprises: a vertical storage pit, a discharge channel, a cleaning pit, a hydraulic cabin, and containers for recovering the recyclable waste. Another variant is the (type 2A) collection and storage station (see the figure for the abstract), with a storage capacity of 81m3. The use thereof involves the use of durable containers. Placed at waste-depositing points, these durable containers enable household refuse produced by homes remote from the storage station to be collected therein, and then emptied out into the storage pit of the nearest collection station. This station is composed of: a vertical storage pit, a discharge channel, a cleaning pit, a hydraulic cabin, containers for recyclable waste, a container-lifting cage, and a pulley / tipping system for emptying the waste containers into the vertical storage pit.

Description

[0001] Method and station for the collection, storage and removal of waste produced by households and in markets - DESCRIPTION OF THE INVENTION

[0002] I - 1: INTRODUCTION

[0003] The present invention relates to a method and station for collecting, storing, and removing waste produced by households and markets. It addresses, in particular, the problem of household waste collection and removal, and the unsanitary conditions caused by household waste littering the streets of our cities.

[0004] Indeed, given uncontrolled urban development, a dynamic population, and the fact that not all homes are accessible by paved roads, the collection of household waste from homes is not a given. This household waste is not sorted by households, who simply dump it in steel bins placed at the roadside.

[0005] In Cameroon, for example, the company Hysacam is responsible for the collection and removal of household waste in several cities. This company deploys considerable resources in terms of:

[0006] Vehicles: Purchase and maintenance of a fleet of over one hundred trucks - Personnel: Roadside garbage collection requires a significant workforce - Equipment: Collection bins and containers exposed to the elements deteriorate rapidly when in contact with wet household waste - Fuel: Given the increase in petroleum product prices, it is imperative to adopt strategies to reduce this cost. Indeed, a truck carrying a bin generally contains less than 10 tons of garbage, while more than 750 tons of household waste are produced in Yaoundé every day.

[0007] Despite all these resources deployed, the population retains a feeling of neglect towards local authorities. The high cost of these services hinders the development of local communities.

[0008] I - 2: STATE OF THE TECHNOLOGY

[0009] From publication WO / 2010 / 041969, an underground waste collection system is known. This system comprises an underground pit, a waste container, a storage silo, and a lid with automatic opening and closing. The container is collected by means of an automated crane with automatic hooking to facilitate collection.

[0010] The main drawbacks of this system are that the container's volume (less than 10m³) and the size of the collection truck do not allow for the collection of large quantities (for example, more than 50m³), thus limiting the cost of waste transport. Similarly, the cost of this installation and its maintenance prevents its widespread adoption to collect all the waste produced in a city.

[0011] It is also known from publication FR2461664, a WASTE CONTAINER WITH SUPPORT AND HANDLING MEANS. It consists of a container whose base is composed of two jaws, pivoting around axes symmetrically by means of two toothed sectors, which jaws have rollers at their ends which, when placed against V-blocks positioned on a base, cause the jaws to open fully.

[0012] One of the technical problems posed by the use of such a device is the container's resistance to weathering and household waste. Similarly, its mass production is costly, and the problem of reducing transportation costs remains unresolved. I - 3: SUMMARY DESCRIPTION OF THE INVENTION

[0013] The present invention therefore aims to remedy these drawbacks. More specifically, the present invention proposes a collection, storage, and removal station for waste produced by households in small areas with high waste production, such as markets, housing estates, social housing, camps, and factories.

[0014] According to various features of the invention, the collection station, the subject of the present invention, comprises: A vertical or horizontal storage pit, a waste evacuation channel, a lifting cage and weighbridge for handling and emptying waste bins into the storage pit (type 2 station), bins for the recovery of recyclable waste, and hydraulic equipment (cylinders, winch) for emptying the pits, and loading the trucks.

[0015] Other features and advantages of the invention will become apparent upon reading the detailed description that follows. For an understanding of this description, reference should be made to the accompanying drawings, in which:

[0027] Figure 30 is an excerpt from the catalog of a global supplier of hydraulic cylinders I-4: DESCRIPTION PROPER

[0028] The Type 1 collection and storage facility is the solution for collecting and storing waste in small areas with high waste production, such as markets and housing complexes (housing estates, social housing, camps, factories, etc.). It allows for the collection and storage of significant volumes of household waste in a vertical pit with a capacity of 54 m³, before collection by a semi-trailer tipper truck (1). The storage capacity of the vertical pit can be adapted according to its cross-section and height.

[0029] Figures 2, 3 and 4 show, in 3D, a TYPE 1 COLLECTION AND STORAGE STATION with a capacity of 54 m3, approximately 32 tonnes, located on 35 m 2 (7m x 5m). It consists of:

[0030] A vertical storage pit (3) with a height of 11.5m and a cross-section of 9m 2 (3m x 3m). The storage pit is buried to a depth of 6m. Its buried walls are constructed of concrete on an insulated strip foundation. The walls are insulated externally with a waterproof thermal insulation material (extruded PVC) and internally with a layer of bitumen. - The vertical storage pit is fed with household waste via a feed hatch (11) accessible by a staircase and a ramp (12) which raises it to a height of 1m.

[0031] At the bottom of the storage pit is installed a discharge jack (2), whose 7m stroke allows the waste to be pushed into the discharge channel (6). - A discharge jack (7) installed in the discharge channel pushes the waste, which is then emptied into the skip of the waste truck positioned below the outlet of the discharge channel. The concrete walls of the skip are insulated internally with bitumen.

[0032] At bottom dead center, the platform of the discharge cylinder (5), located 2.5 m from the bottom of the pit, rests on 4 posts (13), supporting the weight of the waste stored in the vertical pit. Thus, the storage capacity of the vertical pit filled with waste up to the feed opening is: (3.5 m + 2.5 m) x 9 m 2 = 54 m3 or approximately 32 tonnes of household waste.

[0033] The emptying cylinder is fixed to a raised base 50cm high, allowing waste insulation to accumulate at the bottom of the pit. The continuous base of the storage pit must be well sealed and insulated to prevent liquid waste from seeping in.

[0034] A cleaning pit (9), also with concrete walls, provides access to the bottom of the storage pit for cleaning and maintenance. Its opening must be closed to prevent unauthorized access. - The bucket of the discharge cylinder (55) is returned to its starting position by means of a metal rope pulled by a return winch (61) (Figure 18).

[0035] - All these hydraulic equipment (draining and evacuation cylinders, winch) are connected by means of hydraulic hoses to a hydraulic terminal installed in a hydraulic cabin (4). And are operated by the hydraulic pressure supplied by the hydraulic power unit (motor, hydraulic pump, oil reservoir, etc.) of the semi-trailer tipper truck that came to empty the pit.

[0036] Four recycling bins (8) allow for the collection of recyclable waste (plastics, cardboard, paper, metals, and glass). These bins can be installed in a pit or fixed directly to the ground.

[0037] Figures 5, 6, 7 and 8 show, in 3D, a type 2A collection and storage station located on 49m 2(7m x 7m). This installation is the solution for collecting and storing household waste produced by homes located far from the collection and storage facility. Its operation involves the use of reusable bins (Figure 6). These bins, installed at the drop-off points, are collected and emptied into the upper opening (21) of the vertical storage pit at the nearest type 2A collection facility.

[0038] Collection and storage stations are essentially decentralized storage facilities located near communities. Their storage capacity can exceed 80m³. Thus, in addition to all the functions of a type 1 collection and storage station

[0039] The type 2A collection and storage station is equipped with a bin lifting cage (14). Its floor (16), shown in Figure 31, has an area of ​​14 m². 2 , can hold up to 9 durable waste bins, or approximately 9 tonnes of household waste.

[0040] This floor is raised by means of a hydraulic jack (16) installed in a pit under the floor, or by a lifting bridge.

[0041] The bins filled with garbage are retrieved using a manual pallet jack at a height of 5.7 m and emptied into the upper opening (21) of the 9 m² vertical storage pit. 2 (3m x 3m), using a pulley-cantilever system (15) (figures 11 and 12)

[0042] In this configuration, the height of the household waste in the vertical pit, filled to its top opening, is 9m (11.5m - 2.5m). Therefore, the storage capacity of the vertical pit is 9m x 9m. 2 = 81 m3. That's about 49 tonnes of household waste.

[0043] The storage capacity of the vertical pit can be adapted according to its dimensions.

[0044] The other details of figures 5, 6, 7, 8, 11 and 12 are explained below.

[0046] (18): Drain cylinder

[0047] (19): 4 support posts for the drain cylinder platform at bottom dead center

[0048] (20): Discharge cylinder platform at bottom dead center, 2.5m from the bottom of the pit

[0049] (22): Power supply window

[0050] (23): The 2 access doors to the bin lifting cage

[0051] (24): Staircase and access hatch to the bin elevator cage at a height of 5.7 m

[0052] (28): Lever arm of 4.5 m for reducing the manual effort required

[0053] (29): 4 brackets for securing the waste bin to the tipper

[0054] (30): Tilt attachment arm for the hoist

[0055] (27): Tilting axle, solid steel tube 5 cm in diameter, L = 60 cm

[0056] (31): Seating and securing the waste bin

[0057] The operation of a type 2A collection station involves the installation of a hydraulic power unit (motor, pump) to operate the cylinder of the bin elevator. Given the work at height (5.7m), the following safety measures must be adopted:

[0058] 1- Marking off with guardrails and covering the slab located at a height of 5.7m

[0059] 2- Installation of anchor points, allowing the floor of the bin elevator to be attached when it is at top dead center at a height of 5.7m.

[0060] 3- This safety instruction will be carried out before the removal of the garbage bins from the elevator floor by the operator using a pallet jack.

[0061] 4- Similarly, the container will be attached to an anchor point during its emptying.

[0062] Figures 13, 14, 15, 16, and 17 show diagrams and photographs of a durable container manufactured by the inventor. This collapsible container has the following external dimensions: L = 1.2 m; W = 1.2 m; H = 1.5 m. The storage capacity of this container is 1.5 m³, approximately 1 tonne. It is composed of:

[0063] The 4 pillars: Made up of 4 angle brackets measuring 60x60x8mm and 1.5m in length

[0064] The frame (32): Designed for handling with a pallet jack, it is made by welding together six 1.16m lengths of 25x10mm flat iron and four 1.18m lengths of 25x10mm flat iron. Once manufactured, the frame is welded and screwed to the four pillars.

[0065] The bottom support (33): It consists of two 1.18 m lengths of 60x60x8mm angle iron, welded to the four pillars and the frame. It also serves as a base for the three reinforced concrete slabs (39) that close the bottom of the tank.

[0066] The 3 side walls (37) (38): Each side wall is made by threading 4 lengths of 1.15m of durable panels between 2 lengths of 1.2m of 50x25x5mm U iron welded onto the 4 pillars (figure 13).

[0067] The discharge gate (34): It is made by threading four 1.15m lengths of durable panels between two 1.2m lengths of 50x25x5 U-shaped steel. The resulting hinged gate is then fitted with two locking keys (40). Opening the gate and tilting the container, which is secured on a tilting platform, using a hoist, allows the container to be emptied into the vertical storage pit.

[0068] The durable panel: This is a 1.15m long plank made of very hard wood, 30cm wide and between 3 and 4cm thick, with excellent resistance to impact and weathering. This is the case with Azobe, a very hard, rot-resistant wood species found in the equatorial forests of Africa, and often used for very demanding applications (bridges, posts, railway sleepers).

[0069] This very hard wooden board is then covered with a layer of bitumen or with a bitumen-aluminium membrane for better resistance to organic waste (37) (38).

[0070] The capacity of the durable container depends on its dimensions; they must allow for easy handling by pallet jack and optimal use of the collection crane truck.

[0071] The other details of figures 13, 14, 15, 16 and 17 are explained below.

[0072] (35): The 4 plates and 8 clamping holes of the waste bin on the manual tipper

[0073] (36): The bitumen-coated steel structure of the sustainable waste container

[0074] Figures 9 and 10 show, in 3D, a 2B type collection and storage station.

[0075] This installation aims for the same objectives as the type 2A collection and storage station. However, the waste bins are emptied into a horizontal storage pit (25).

[0076] A hydraulic cylinder installed in the horizontal pit then pushes the waste into the vertical pit. A feed window (26) also allows the vertical storage pit to be fed.

[0077] The storage capacities of the horizontal and vertical pits vary depending on their dimensions. The horizontal pit's discharge bucket is retrieved by a winch located behind the hydraulic cylinder. Maintenance of the vertical and horizontal pits, as well as the discharge channel, consists of pressure washing the interior walls and renewing the bitumen layer. I - 4- 5: HYDRAULIC CYLINDERS

[0078] I - 4- 5a: Selection of cylinders

[0079] The cylinders used in the collection and storage stations described above are single-acting telescopic hydraulic cylinders:

[0080] The discharge jack installed in the vertical storage pit must travel a distance of 7 m and vertically push a load of 81 m³ of household waste, or approximately 49 tonnes. The pistons return to their starting position under the effect of their own weight and that of the discharge platform, which weighs more than 2 tonnes.

[0081] The evacuation jack working in the evacuation channel must travel a distance of 5.5m and horizontally push a load of 9m3 of household waste, or approximately 5.4 tonnes.

[0082] The bin lifting cylinder must travel a distance of 5.7m and vertically lift a load of 9 tonnes.

[0083] The horizontal pit emptying jack must travel a distance of 5m and push a load of 20m³ of waste horizontally, or approximately 12 tonnes.

[0084] The IX-X diagram is an excerpt from the catalog of a world-leading manufacturer of hydraulic cylinders and lifting equipment. Within the FE range of telescopic cylinders, several cylinders can meet the requirements identified above; namely:

[0085] The FE A157-5-05830-011-K1449 cylinder: This cylinder can be used as a discharge cylinder, a bin lifting cylinder, and a horizontal pit cylinder. With a rest length of 1449 mm, its stroke is 5830 mm after five extensions. Its load capacity varies from 47 to 27 tons between the first and fifth extensions.

[0086] FE A191-5-06830-011-K1672 as a vertical storage pit emptying cylinder. Its 6830 mm stroke allows it to empty the vertical pit above the emptying platform. Its load capacity varies between 49 and 78 tonnes, under a pressure of 190 bar. l-4-5b: Cylinder mounting and guidance

[0087] Figures 20, 21, 22 and 23 represent in 3D the 4 stages of the equipment and assembly of a hydraulic cylinder with: the discharge platform of the vertical storage pit, or the floor of the bin lifting cage, or the bucket of the discharge channel.

[0088] The other details of figures 20, 21, 22 and 23 are explained below:

Figures 24, 25, 26, and 27 show the equipment and mounting of the FE A157-5-05830-011-K1449 telescopic cylinder in the discharge channel (59). The horizontal stroke of this cylinder requires the installation of a guide rail (54) and a winch (61) for retracting the discharge bucket (55).

[0102] Tensioners ensure proper distribution of the cylinder's thrust.

This structure, made of welded steel elements (120x120x12, 140x140x12 angle bars, 100x10 flat bar), has a surface area ranging from 4 to 15 m². 2 It serves as a base for 16 reinforced concrete slabs (66) or a thin sheet of metal 5 mm thick (68). A plate (60x60cm) (65) allows for assembly with the jack. Lifting points (64) allow for handling, and tensioner mounting brackets (67) ensure proper distribution of the jack's thrust. A bituminous coating protects it from the elements.

[0110] 1-5: Description of the waste collection and removal process

[0111] The present invention also relates to a method for collecting and removing waste. This method, using the collection point described above, consists of: collecting waste from designated drop-off points into durable containers, grouping large volumes (e.g., 80 m³) of waste into storage pits, and removing them using semi-trailer tipper trucks capable of transporting up to 55 m³ of waste in a single trip.

[0112] 1-5-1: Case study of the city of Yaoundé

[0113] The city of Yaoundé has an urbanized area of ​​200km² 2 which produces approximately 750 tons of household waste per day. The appropriate solution is to create a grid system throughout the city to install collection and storage points for type 2A waste, along with durable waste bins at designated drop-off points. This will ensure that every household in Yaoundé is within 200 meters of a drop-off point.

[0114] Questions: How many collection points, drop-off points, and durable bins are needed?

[0115] If we assume that the 750 tonnes of waste are collected and stored daily in vertical pits, and are removed by semi-trailer dump trucks carrying 55 m3 (33 to) of waste per rotation, then 23 rotations of semi-trailer dump trucks will be required each day.

[0116] Given the mechanization of the emptying and loading process for these trucks, each truck can make at least two trips per day. Therefore, an efficient fleet of 12 semi-trailer tipper trucks will be required.

[0117] Each durable bin has a capacity of lt, so 750 bins will need to be collected each day and emptied into a type 2A station.

[0118] This work is carried out by trucks equipped with cranes, each capable of collecting up to 50 bins per day. Therefore, an efficient fleet of 15 crane-equipped trucks will be needed. Each truck will collect 10 waste bins per trip, completing 5 trips per day.

[0119] Given that a type 2A waste collection and storage station has a storage capacity of 81 m³ (49 tonnes), a daily removal of 750 tonnes of waste corresponds to the daily emptying of 15 type 2A collection and storage stations. If we consider that each station will be emptied once every two days, then 30 type 2A stations will need to be installed throughout the city of Yaoundé.

[0120] - Thus, each type 2A waste collection and storage station covers an area of ​​6.6 km 2 (200 / 30). This makes it possible to collect and empty 750 bins / day using 15 crane trucks, with reduced fuel consumption.

[0121] If we assume that 200m is the maximum distance between a home and its nearest drop-off point, then we can deduce that each drop-off point occupies the center of a square grid with sides of 282m (282 = 2 x square root of ((200 x 200) / 2)). Each drop-off point therefore covers an area of ​​79761 m². 2 , or 0.08km 2

[0122] A total of 2500 collection points will therefore be needed in the city of Yaoundé.

[0123] (2500 = (200 / 0.08)).

[0124] If we place an average of two reusable waste bins at each collection point, we will need to install 5,000 reusable waste bins throughout the city of Yaoundé. The collection frequency will be adjusted according to the bins' fill level.

[0125] In addition, a fixed reinforced concrete container can be installed at each collection point for recyclable waste (plastics, cardboard, paper, glass). This recyclable waste will then be available to social actors active in the artisanal or industrial recycling of this waste.

[0126] 1-5-2: Evaluation of savings achieved

[0127] Fuel: the fuel savings achieved are around 37%.

[0128] A crane truck (140-190 hp engine) consumes an average of 8,000 FCFA in fuel to transport 10 durable bins (10 tonnes) and empty them at the nearest Type 2A waste disposal site. This equates to a consumption of 800 FCFA per tonne, and therefore 26,400 FCFA for 33 tonnes. A semi-trailer dump truck removes 33 tonnes (55 m³) of garbage from the vertical storage pit. It consumes an average of 25,000 FCFA to complete this trip between the NKOLFOULOU landfill and a Type 2A waste collection site in the city of Yaoundé.

[0129] The Hysacam hooklift truck removes 10 tonnes (15m3) of waste on each trip. It consumes an average of 25,000 FCFA to complete this trip between the NKOLFOULOU landfill and a waste disposal point in the city of Yaoundé.

[0130] From these 3 hypotheses, we can deduce that:

[0131] The HYSACAM roll-off truck consumes an average of 82,500 FCFA in fuel to remove 33 tons of waste in the city of Yaoundé.

[0132] The difference between the two methods, 82500 - (25000 + 26400) = 31100 FCFA, corresponds to a fuel saving of 37%.

[0133] Waste bins: The production of the durable bin (Figure 16) with a capacity of 1.5 m³ cost 200,000 FCFA (two hundred thousand). At this price, it is possible to manufacture 5,000 of them and make them available to households at collection points. This would prevent unsanitary conditions caused by household waste accumulating along roadsides. However, current steel bins with a maximum capacity of 16 m³ (10 tons) cost more than 1.5 million FCFA and deteriorate more quickly.

[0134] I -5-3: Study of the Etoudi market case

[0135] The Etoudi market, located in the city of Yaoundé, occupies an area of ​​less than 90,000 m² 2(300m x 300m). The garbage collected by the maintenance workers is piling up on the sidewalks. Collection is difficult due to the volume produced and traffic congestion. The solution here is the installation of a type 1 collection and storage station.
