[0004] 63 / 733,694 filed March 18, 2025 and titled “INSECT BIOCONVERSION SYSTEMS AND RELATED METHODS”, the entire contents of which are hereby incorporated by reference for all purposes.
[0005] FIELD
[0006] [2] The described embodiments relate generally to bioconversion of organic waste, and in particular systems and methods for using insects to process organic waste.
[0007] INTRODUCTION
[0008] [3] The following paragraph is not an admission that anything discussed therein is prior art or part of the knowledge of persons skilled in the art.
[0009] [4] As the world population continues to rise and climate change threatens food security, there has been increasing interest in insects as source of protein for animal feed. In addition, insects can also assist in reducing organic waste as they naturally feed on organic waste. For example, black soldier fly larvae (BSFL) can be reared to feed on organic waste. Subsequently, the BSFL can be harvested as protein for animal feed and their excrement can be harvested for fertilizer. Thus, this process converts organic waste to produce animal feed and fertilizer.

It will be appreciated that for simplicity and clarity of illustration, where considered appropriate, reference numerals may be repeated among the drawings to indicate corresponding or analogous elements or steps.
[0051] DESCRIPTION OF EXAMPLE EMBODIMENTS
[0052]
[0046] Disclosed herein are systems and methods relate to insect bioconversion of organic waste. Organic waste is produced everywhere - homes, commercial facilities, industrial facilities, farms, and many more. Disposal of organic waste generally represents an expense. Instead, organic waste can be bio-converted to avoid disposal expenses. However, collecting and transporting organic waste from distributed sites to a central location for bioconversion is costly. It can be more efficient to process organic waste on-site, that is, at the location where the organic waste is produced.
[0053]
[0047] Conventional systems and methods for insect bioconversion of organic waste can involve many steps that require manual intervention, such as loading the organic waste and insect larvae, monitoring the organic waste and larvae until the insect bioconversion process is complete, and unloading the waste products. Such manual intervention can be expensive and make insect bioconversion difficult to scale. Further, when processed on-site, organic waste producers simply wish to dispose of the organic waste and are generally not knowledgeable nor interested in managing the bioconversion process.
[0054]
[0048] Referring now to FIG. 1, shown therein is an example insect bioconversion system 100, according to some embodiments. To assist with the description of bioconversion system 100, reference will be simultaneously made to FIG. 2 to FIG. 11. Insect bioconversion system 100 includes a housing 102, a plurality of stacked trays sets 110, a conveyor assembly 122, and a heating, ventilation, and air conditioning (HVAC) assembly.
[0055]
[0049] The housing 102 has a longitudinal axis L. As shown, the housing can be elongated along the longitudinal axis L. The housing includes a roof 108 (shown in FIG. 2) and a floor 112 (shown in FIG. 2). The housing 102 has sidewalls 106A, 106B(shown in FIG. 2) (herein collectively referred to as sidewalls 106) that extend along the longitudinal axis L from a first end A to a second end B. At the first end A, the housing 102 has doors 104A. At the second end B, which is opposite to the first end A, the housing 102 has doors 104B. As shown, doors 104A, 104B (herein collectively referred to as doors 104) are openable and can be shut to enclose or seal the contents of the housing 102 therein. The doors 104 span the full width of the housing 102. When open, the doors 104 provide access to the full width of the housing 102, allowing the interior of the housing 102 accessed by an operator or a machine, such as a forklift, an autonomous robot, or other vehicle. With doors on both ends of the housing 102, access to the contents therein from two ends allow for more efficient workflow.
[0056]
[0050] As shown, the housing 102 can be a pre-fabricated shipping container. Pre-fabricated shipping containers typically have standard dimensions. For example, pre-fabricated shipping containers have a standard width of 8 feet. Pre-fabricated shipping containers can have a length of 20 feet, 40 feet, or 45 feet and a height of 8.5 feet or 9.5 feet. Other dimensions are possible. In some embodiments, the housing 102 can be insulated.
[0057]
[0051] Referring now to FIG. 2, shown therein is a view of the bioconversion system 100 from the second end B. The conveyor assembly 122 facilitates movement of the plurality of trays within the housing 102. The conveyor assembly 122 includes at least one pair of tracks. As shown in FIG. 2, the conveyor assembly 122 includes two pairs of tracks, 122Aand 122B. Each track 122A1 and 122A2 of the pair of tracks 122A are spaced apart to provide an access passage 122A3 therebetween. Similarly, tracks 122B1 and 122B2 are spaced apart to provide another access passage 122B3. Each track 122A1 , 122A2, 122B1 , 122B2 can be a roller track (shown in FIG. 9 to 11 ). The roller track can be manual, motorized, and / or automated. Other types of tracks or rails are possible.
[0058]
[0052] The conveyor assembly 122 receives the plurality of stacked trays sets 110 thereon. As shown, in FIG. 1, the bioconversion system 100 can include eight stacked trays sets 110A, 110B, 110C, 110D, 110E, 110F, 110G, and 110H, half of which are placed on each of tracks 122A and 122B. As shown in FIG. 2, each stacked trays set, such as 110D, includes four trays 110D1, 110D2, 110D3, and 110D4 stacked vertically, that is, on top of one another. Although four stacked trays sets areshown for each pair of tracks 122A, 112B and four trays are shown in each stacked trays set 110 in example bioconversion system 100, each track can include fewer or more stacked trays sets and / or each stacked trays set 110 can include fewer or more trays. Further, the stacked trays sets within a system can include a different number of trays and the tracks can include a different number of stacked trays sets.
[0059]
[0053] Referring now to FIG. 3, shown therein is an interior view of the bioconversion system 100 from the side. As shown in FIG. 3, each pair of tracks 122A, 122B extends from the first end A of the housing 102 to the second end B of the housing 102. Accordingly, the conveyor assembly 122 can move the plurality of stacked trays sets 110 from the first end A to the second end B within the housing 102. That is, the conveyor assembly 122 can move the plurality of stacked trays sets 110 along the longitudinal axis. As shown in FIG. 3, the length of the conveyor assembly 122 between the first end A to the second end B can accommodate four adjacent stacked trays sets 110D, 110C, 110B, and 110A. The ability to move the stacked trays sets 110 allows for easier batch processing of the trays 110.
[0060]
[0054] Returning now to FIG. 2, the access passage 122A3, 122B3 provide space for a lifting member to be inserted underneath a stacked trays set 110H, 110D. The lifting member can be raised out of the access passage 122A3, 122B3 to lift the stacked trays set 110 off the conveyor assembly 122 for unloading the stacked trays set 110 from the conveyor assembly 122. Conversely, a lifting member can load the stacked trays set 110 onto the conveyor assembly 122 by lowering the stacked trays set 110 onto the conveyor assembly 122. As the lifting member lowers into the access passage 122A3, 122B3, the conveyor assembly 122 receives the stacked trays set 110 and the stacked trays set 110 is transferred to the conveyor assembly 122.
[0061]
[0055] The lifting member can, for example, be forks of a forklift. In another example, the lifting member can be end-of-arm tooling of a robotic device. In some embodiments, the lifting member can be a part of an autonomous vehicle. For example, the robotic device or the forklift can be autonomous. Use of the lifting member can reduce the manual intervention usually required to load the trays 110 into the housing 102. Further, the lifting member and the conveyor assembly can reduce the manual intervention typically required for arranging the trays 110 within the housing 102.
[0056] In some embodiments, one or more rails can be affixed to the interior of sidewalls 106 of the housing 102. As shown in FIG. 2, four rails 124A1, 124A2, 124A3, 124A4 (herein collectively referred to as rails 124A) can be mounted to sidewall 106A. Similarly, four rails 124B1, 124B2, 124B3, 124B4 (herein collectively referred to as rails 124B) can be mounted to sidewall 106B. As shown in the top plan view of FIG. 5, the rails 124A, 124B (collectively referred to as rails 124) extend along the longitudinal axis, from the first end A of the housing 102 to the second end B of the housing 102. The rails 124 are positioned at elevated heights along the sidewalls 106. As shown, the rails 124 are positioned at four different elevations, with one elevation for each level of trays within the stacked trays sets 110H, 110D.
[0062]
[0057] Referring now to FIG. 6 and FIG. 7, shown therein is an end view and a side view of an example tray 110. The external dimensions of each tray 110 can be height 112z, width 112X, and length 112Y. For example, in some embodiments, each tray can have a height of approximately 20 inches, a width of approximately 40 inches and a length of approximately 48 inches. Other dimensions are possible. For example, shallower trays can improve the insect bioconversion process with greater ventilation. However, the tradeoff with shallower trays is less capacity.
[0063]
[0058] Each tray 110 can have downwardly extending supports 114A, 114B, 114C (herein collectively referred to as downwardly extending supports 114). The outer downwardly extending support 114A and the inner downwardly extending support 114B are spaced apart to provide a ventilation passage 116A therebetween. Also, the outer downwardly extending support 114C and the inner downwardly extending support 114B are spaced apart to provide another ventilation passage 116B therebetween. When a tray 110 is stacked on top of another tray 110, the ventilation passages 116A, 116B allow air flow to the lower tray 110.
[0064]
[0059] As can be seen from the side view in FIG. 7, each of the downwardly extending supports 114 can extend along the length 112Y of the tray 110. Further, the downwardly extending supports 114 can define one or more ventilation windows therein. For example, two ventilation windows 116C and 116D are defined within the outer downwardly extending support 114A. Similar to ventilation passages 116A and 116B, ventilation windows 116C and 116D allow air to flow to the lower tray 110. Although ventilation window 116C, 116D are shown as being rectangular shapes,other shapes are possible. Further, although example tray 110 includes two ventilation windows 116C, 116D, other trays can include fewer or more ventilation windows.
[0065]
[0060] In some embodiments, the downwardly extending supports 116 may not extend along the length 112Y of the tray 110. Instead, additional downwardly extending supports can be provided along the length 112Y. Further, the downwardly extending supports along the length 112Y can also be spaced apart to provide additional ventilation passages, similar to ventilation passages 116A, 116B to allow air flow to the lower tray 110.
[0066]
[0061] In some embodiments, each stacked trays set 110A, 110B, 110C, 110D, 110E, 110F, 110G, 110H can consist of the trays 110 only. That is, the trays 110 are self-stackable, directly on one another. In some embodiments, the downwardly extending supports 114 can have bottom engagement surfaces 118B for engaging with a lower tray, that is, another tray immediately below it. In some embodiments, trays 110 can have top engagement surfaces 118T for engaging with an upper tray, that is, another tray immediately above it. Further, in some embodiments, the bottom engagement surfaces 118B can have grooves or protrusions to engage with top engagement surfaces 118T that are complementary to the grooves or protrusions. In some embodiments, the top and bottom engagement surfaces 118T, 118B can be flat to engage with one another.
[0067]
[0062] Returning now to FIG. 2, when the stacked trays sets 110 consist of the trays 110 only, the downwardly extending supports 114 rest directly on the conveyor assembly 122 (as shown in FIG. 10 and FIG. 11). For example, the spacing between the outer downwardly extending supports 114A, 114C aligns with the spacing between the pair of tracks 122A1, 122A2, that is, the access passage 122A3. Thus, the downwardly extending supports 114 engage with the tracks of the conveyor assembly 122. Further, the width 128W of each track of the conveyor assembly 122 is sufficient for receiving the outer downwardly extending supports 114 (shown in FIG. 10 and FIG.
[0068] 11). In some embodiments, the width 128W of each track of the conveyor assembly 122 can be approximately 6 inches.
[0069]
[0063] In other embodiments, the stacked trays sets 110 can include a rack, a pallet, or other carrier for carrying the plurality of trays thereon. With a pallet, the trays 110 sit directly on top of one another and the lowermost tray rests on the pallet. Witha rack, two or more trays 110 can be held by horizontal supporting members of the rack. In some embodiments, the rack can also include one or more aerator or agitation devices to mix the contents of the trays.
[0070]
[0064] In some embodiments, the trays 110 can include lateral engagement surfaces along an end sidewall 118S. The lateral engagement surfaces can engage another tray within an adjacent stacked trays set. For example, with reference to FIG.
[0071] 5, when force is applied to stacked trays set 110A in a direction from the first end A to the second end B, the lateral engagement surfaces of trays 110A can engage with adjacent trays 11 OB and move the adjacent stacked trays set 11 OB towards second end B.
[0072]
[0065] The insect bioconversion process, also referred to as the rearing period, takes place in each tray 110 having organic waste and insect larvae. The insect bioconversion process can depend on various factors, including the type of insect, the nature of the organic waste (e.g., pH level), the proportion of insect larvae to waste, and environmental factors, such as but not limited to the lighting, temperature, and humidity. In some embodiments, one or more sensors (not shown) can be provided within each tray 110 to monitor the insect conversion process within that tray 110. For example, one or more sensors can be provided to measure the temperature, humidity, carbon dioxide, oxygen, and / or pH level within that tray 110.
[0073]
[0066] The HVAC assembly can regulate the temperature and humidity within the housing 102. In some embodiments, the HVAC assembly can include one or more extractor fans 130 to circulate air throughout the housing 102, including through the ventilation passages 116A, 116B and / or the ventilation windows 116C, 116D. As shown in FIG. 4, the extractor fan 130 can be mounted on one or more sidewalls 106A, 106B. Also, one or more heaters 132 and / or air conditioning units can also be mounted to the sidewalls 106A, 106B. For example, the housing 102 can be a refrigerated shipping container. In some embodiments, the housing 102 can include two heaters or four heaters. Fewer or more heaters can be included. Although FIG. 2 and 8 shows the elevation 132X of the heater 132 along the sidewall 106 to be between the elevation of the uppermost tray 110H1 and second uppermost tray 110H2, other elevations are possible.
[0067] In some embodiments, the HVAC assembly can also include at least one dehumidifier 136. The dehumidifier 136 can assist with moisture control. In particular, the dehumidifier 136 can reduce the humidity as moisture is generated and can accumulate from the bioconversion process. As shown in FIG. 3, the dehumidifier 136 can be mounted on the roof 108 of the housing 102. In some embodiments, the insect bioconversion system 100, including components of the HVAC assembly, can be remotely monitored and controlled.
[0074]
[0068] In some embodiments, one or more light fixtures can also be provided in the housing 102. One or more light fixtures (herein referred to as lighting) can be mounted to the roof 108, the sidewalls 106A, 106B, and / or the doors 104A, 104B. In some embodiments, lighting can be positioned to illuminate select stacked trays sets 110. For example, lights can be mounted at four locations along the length of the sidewalls 106A and 106B to illuminate a corresponding row of stacked trays sets. For example, a first row can include stacked trays sets 110A and 110E; a second row can include stacked trays sets 110B and 110F; a third row can include stacked trays sets 110C and 110G, and a fourth row can include stacked trays sets 110D and 11 OH. In some embodiments, light fixtures can be provided within one or more trays 110.
[0075]
[0069] In some embodiments, one or more sensors (not shown) can be provided within the housing 102 to monitor the environmental conditions. For example, one or more sensors can be provided within the housing 102 to measure the temperature, humidity, carbon dioxide and / or oxygen within the housing 102. The measurements taken within individual trays 110 can be compared with the measurements taken within the housing 102. The HVAC assembly and lighting can be controlled based on the environmental conditions detected.
[0076]
[0070] Junction box 134 can provide utilities, such as electrical power and data communication network connections to one or more components of the HVAC assembly, including but not limited to the extractor fan 130, heater 132, and dehumidifier 136, or lighting. In some embodiments, the junction box 134 can include a power control switch to activate or deactivate one or more components of the HVAC assembly or lighting. In some embodiments, the housing 102 can include an energy consumption meter.
[0071] In some embodiments, the housing 102 can include an electrical panel positioned on a sidewall 106A, 106B for easier access. The electrical panel can easier allow for service of the bioconversion system 100. The electrical panel can include an emergency shut-off switch for electrical power and data communication.
[0077]
[0072] Referring now to FIG. 12, there is illustrated a schematic block diagram 200 of an exemplary insect bioconversion monitoring system 220, in accordance with at least some embodiments. The insect bioconversion monitoring system is generally identified by reference numeral 220.
[0078]
[0073] The insect bioconversion monitoring system 220 includes a processor 222, a storage component 224, and a communication component 226. Each of these components may be divided into additional components or combined into fewer components. The insect bioconversion monitoring system 220 can be local to, or onsite with the bioconversion system 100. In some embodiments, the insect bioconversion monitoring system 220 can be remote from the bioconversion system 100. The insect bioconversion monitoring system 220 can be a server including but not limited to, for example, a hardware server, virtual server, cloud server etc. Generally, the insect bioconversion monitoring system 220 can receive monitoring data from one or more sensors 212. The one or more sensors 212 can include sensors within individual trays 110, sensors within the housing 102, and / or the energy consumption meter.
[0079]
[0074] The insect bioconversion monitoring system 220 can control components of the bioconversion system 100, such as components of the HVAC assembly 214 or lighting 216, based on the monitoring data received from the sensors 212. For example, the insect bioconversion monitoring system 220 can activate or deactivate the lighting 216 or HVAC components 214, such as but not limited to extractor fan 130, heater 132, and dehumidifier 136, based on a comparison of parameters in the monitoring data and pre-defined conditions.
[0080]
[0075] The storage component 224, or memory, can include RAM, ROM, one or more hard drives, one or more flash drives or some other suitable data storage elements such as disk drives. For example, the storage component 224 can include volatile and non-volatile memory. Non-volatile memory can store computer programs consisting of computer-executable instructions, which can be loaded into the volatilememory for execution by the processor 222. Operating the processor 222 to carry out a function can involve executing instructions (e.g., a software program) that can be stored in the storage component 224 and / or transmitting or receiving inputs and outputs via the communication component 226. The storage component 224 can also store data input to, or output from, the processor 222, which can result from the course of executing the computer-executable instructions, for example.

In some embodiments, the processor 222 can include more than one processor with each processor being configured to perform different dedicated tasks.
[0084]
[0079] The communication component 226 can include any interface that enables the insect bioconversion monitoring system 220 to communicate with various devices and other systems. For example, the communication component 226 can facilitate communication with computing device 210, sensor 212, HVAC component 214, lighting 216, and external storage component 240 via the communication network 230. Although only one computing device 210, one sensor 212, one HVAC component 214, one lighting component 216, one communication network 230, and one externalstorage component 240 is shown in FIG. 12, the communication component 226 can facilitate communication with any number of computing devices 210, sensors 212, HVAC components 214, lighting components 216, communication network 230, and external storage components 240. For example, the communication component 226 can facilitate communication between the insect bioconversion monitoring system 220 and local components such as sensor 212, HVAC component 214, lighting 216 via a local communication network 230a and communication between the insect bioconversion monitoring system 220 and computing device 210 and external storage component 240 via another communication network 230b. This allows the insect bioconversion monitoring system 220 to continue to control the bioconversion system 100 in the event of power outages or other failures that result in an outage of the other communication network 230b.
[0085]
[0080] In some embodiments, the communication component 226 can include at least one of a serial port, a parallel port, or a USB port. The communication component 226 may also include a wireless transmitter, receiver, or transceiver for communicating with a wireless communications network, such as the communication network 230. The wireless communications network can include at least one of an Internet, Local Area Network (LAN), Ethernet, Bluetooth®, Firewire, modem, fiber, or digital subscriber line connection. Various combinations of these elements may be incorporated within the communication component 226. For example, the communication component 226 may receive input from various input devices, such as a mouse, a keyboard, a touch screen, a thumbwheel, a trackpad, a trackball, a cardreader, voice recognition software and the like depending on the requirements and implementation of the insect bioconversion monitoring system 220.
[0086]
[0081] The communication network 230 can include any network capable of carrying data, including the Internet, Ethernet, plain old telephone service (POTS) line, public switch telephone network (PSTN), integrated services digital network (ISDN), digital subscriber line (DSL), coaxial cable, fiber optics, satellite, mobile, wireless (e.g., Wi-Fi®, WiMax®), Signaling System No. 7 (SS7) network, fixed line, local area network, wide area network, and others, including any combination of these, capable of interfacing with, and enabling communication between the insect bioconversion monitoring system 220, the computing device 210, the sensor 212, the HVACcomponent 214, the lighting component 216, and / or the external storage component 240.
[0087]
[0082] In some embodiments, the computing device 210 can communicate with the sensor 212, the HVAC component 214, and / or the lighting 216 via the communication network 230. In some embodiments, the computing device 210 can communicate with the lighting 216, the HVAC component 214 and / or the sensor 212 directly via onboard communication components. For example, each of the computing device 210 and the insect bioconversion monitoring system 220 can be equipped with a wireless communication interface to enable wireless communications according to a Wi-Fi protocol (e.g., IEEE 802.11 protocol or similar).
[0088]
[0083] Similar to the storage component 224, the external storage component 240 can include RAM, ROM, one or more hard drives, one or more flash drives or other suitable data storage elements such as disk drives. Similar to the storage component 224, the external storage component 240 can store data in respect of the insect bioconversion monitoring system 220, the computing devices 210, the sensors 212, the HVAC components 214, and / or the lighting 216 including data related the computing devices 210, the sensors 212, the HVAC components 214, the lighting 216, users, and processing times. Data can be stored in the external storage component 240 for subsequent retrieval by the insect bioconversion monitoring system 220, computing devices 210. Although the external storage component 240 is described and shown as separate from the insect bioconversion monitoring system 220, other configurations are possible. In some embodiments, the external storage component 240 is hosted by the bioconversion monitoring system 220. In some embodiments, the external storage component 240 can be a third-party data storage.
[0089]
[0084] In some embodiments, one or more computing devices, such as computing device 210 can communicate with the insect bioconversion monitoring system 220 via the communication network 230. For example, an operator can access the insect bioconversion monitoring system 220 via computing device 210 to monitor and control the insect bioconversion system 100. In some embodiments, such monitoring and control can be performed remotely and / or in real-time. The operator can configure the parameters of the lighting 216 and the HVAC assembly 214 to provide optimal conditions for the insect bioconversion process, while accounting forthe nature of the organic waste, the weather conditions, electricity prices, and / or energy consumption. For example, the optimal conditions can be dependent on the nature of the organic waste (i.e., corn or peppers). In a first instance, when corn organic waste is loaded in the stacked trays set 110, computing device 210 can configure the insect bioconversion monitoring system 220 to control the bioconversion system 100 based on parameters that correspond to optimal conditions for corn. In another instance, when pepper organic waste is loaded in the stacked trays set 110, computing device 210 can configure the insect bioconversion monitoring system 220 to control the bioconversion system 100 based on parameters that correspond to optimal conditions for peppers.
[0090]
[0085] In another example, computing device 210 can be a central insect bioconversion monitoring system. Generally, the central insect bioconversion monitoring system can receive monitoring data from a plurality of bioconversion monitoring systems 100 and direct or control the insect bioconversion systems 100. In some embodiments, the central insect bioconversion monitoring system can determine parameters and optimal conditions based on, amongst other things, the monitoring data from the plurality of bioconversion monitoring systems 100.
[0091]
[0086] The computing device 210 can include any device capable of communication with other devices through a network such as the communication network 230. The computing device 210 can include a processor and memory, and may be a server, hardware server, virtual server, cloud server, an electronic tablet, a personal computer, workstation, server (e.g., hardware server, virtual server, cloud server etc.), portable computer, mobile device, personal digital assistant, laptop, smart phone, Wireless Application Protocol (WAP) phone, an interactive television, video display terminals, portable electronic devices, or any combination of these. Although only one computing device 210 is shown in FIG. 12 for simplicity, more computing devices can communicate with the insect bioconversion monitoring system 220. Furthermore, although the insect bioconversion monitoring system 220 is shownin FIG. 12 as a separate component from the computing device 210, in some embodiments, it can be combined with the computing device 210.
[0092]
[0087] Reference now is made to FIG. 13, which is a flowchart of an example method 300 for insect bioconversion of organic waste. To assist with the description of method 300, reference will be simultaneously made to FIGS. 1 to 10.
[0093]
[0088] At 302, the method involves opening a first end of a housing. The housing can, for example, be housing 102. Opening a first end of housing 102 can involve opening doors 104A at the first end A.
[0094]
[0089] At 304, a plurality of stacked trays sets is loaded onto one or more pairs of tracks from the first end A. The plurality of stacked trays sets can be, for example, stacked trays sets 110A, 110B, 110C, 110D, 110E, 11 OF, 110G, 11 OH. Each tray of the stacked trays sets carrying organic waste and insect larvae therein. The organic waste and insect larvae loaded within each tray can be a pre-determined amount. In some embodiments, the proportion of organic waste and insect larvae can be optimized for expected conditions for the insect bioconversion process. In some embodiments, additives can be added to facilitate the insect bioconversion process.
[0095]
[0090] In some embodiments, loading a stacked trays set, such as 110A, onto a pair of tracks, such as tracks 122B, from the first end A can involve using a lifting member. The lifting member can carry the stacked trays set 110A to the pair of tracks 122B at the first end A. The lifting member can engage an elongated center portion of a bottom surface of the stacked trays set 110A to lift the stacked trays set 110A. For example, when the stacked trays set 110A consists of the trays only, without a carrier or rack, the lifting member can engage the bottom surface of a lowermost tray, such as tray 110A4, to carry the stacked trays set 110A. In particular, the lifting member can engage an elongated center portion 118E of the bottom surface of tray 110A4 that defines the access passage 122B3. The lifting member can lower the stacked trays set 110A to rest on the pair of tracks 122B. As the stacked trays set 110A are received by the pair of tracks 122B, the lifting member enters the access passage 122B3 between the pair of tracks 122B. The lifting member can be withdrawn from the access passage 122B3. In some embodiments, withdrawing the lifting member from the access passage 122B3 can involve retracting the lifting member.
[0091] In some embodiments, loading the plurality of stacked trays, such as stacked trays sets 110A, 11 OB, 110C, and 110D onto a pair of tracks, such as 122B involves iteratively loading each stacked trays set onto the pair of tracks 122B from the first end A. For example, the stacked trays set 110A can be loaded onto the tracks 122B first. Subsequently, a force can be applied from the first end A to the stacked trays set 110A that is already loaded to move it toward the second end B and make space on the tracks 122B for another stacked trays set. Next, the stacked trays set 110B can be loaded onto the tracks 122B. Again, a force can be applied to the stacked trays set 110B that is proximal to the first end A to move the loaded stacked trays sets 11 OB and 110A toward the second end B and make space on the tracks 122B for another stacked trays set. Similarly, the stacked trays set 110C can be loaded onto the tracks 122B and a force can be applied to the stacked trays set 110C that is proximal to the first end A to move the loaded stacked trays sets 110C, 11 OB and 110A toward the second end B and make space on the tracks 122B for another stacked trays set, namely stacked trays set 110D.
[0096]
[0092] After the one or more pairs of tracks are loaded with stacked trays sets 110, the housing 102 can be closed at 306. In particular, the doors 104A at the first end A can be closed.
[0097]
[0093] At 308, the HVAC assembly is controlled for an insect processing period. During the insect processing period, the insect larvae within each tray 110 processes at least part of the organic waste. The efficiency of the bioconversion can depend on the lighting, temperature and humidity. In some embodiments, the insect processing period can be a duration of approximately 10 to 12 days. In some embodiments, the insect processing period can be less than 10 days. In some embodiments, the insect processing period can be more than 12 days. For example, during the insect processing period, contents of the tray can be occasionally agitated to speed up the insect bioconversion processing rate and thereby shorten the insect processing period. As another example, unexpected weather conditions can slow down or speed up the insect bioconversion processing rate and thereby extend or shorten insect processing period, respectively.
[0098]
[0094] After the insect processing period, at 310, the second end B of the housing 102 is opened. The second end B is opposite to the first end A along thelongitudinal axis L. Opening the second end B of housing 102 can involve opening doors 104B at the second end B. The plurality of stacked trays sets 110 can be unloaded from the one or more pairs of tracks of the conveyor assembly 122 from the second end B. In some embodiments, unloading a stacked trays set, such as 110A, from a pair of tracks, such as tracks 122B, from the second end B can involve using a lifting member. The lifting member can be inserted into the access passage 122B3. In some embodiments, inserting the lifting member can involve extending the lifting member. Within the access passage 122B3, the lifting member can be raised to engage the bottom surface of the stacked trays set 110A and lift the stacked trays set 110A off the pair of tracks 122B. For example, when the stacked trays set 110A consists of the trays only, without a carrier or rack, the lifting member can engage the bottom surface of a lowermost tray, such as tray 110A4. In particular, the lifting member can engage an elongated center portion 118E of the bottom surface of tray 110A4 that defines the access passage 122B3. The lifting member can raise the stacked trays set 110A and carry the stacked trays set 110A away from the second end B.
[0099]
[0095] In some embodiments, the method 300 can be performed “on-site”, that is, at a site producing the organic waste. Such sites typically serve another purpose, and can be, but is not limited to a farm or other industrial facility. In such cases, the housing 102 can be delivered to the site. Loading and unloading the stacked trays sets into and out of the housing, as well as the insect processing period can all take place at the site. Further, in some embodiments, the HVAC assembly installed in the housing 102 before the housing 102 is delivered to the site. In some embodiments, the housing 102 can be delivered to the site and the HVAC assembly installed thereafter.
[0100]
[0096] In some embodiments, the stacked trays sets 110 can be loaded in the housing 102 overtime. For example, when the bioconversion system 100 is on-site, a first set or batch of stacked trays sets 110A and 110E can be loaded from the first end A. After the site accumulates additional organic waste, the additional organic waste can be loaded into the housing 102 in a second batch of stacked trays sets 110B and 11 OF, a later third batch of stacked trays sets 110C and 110G. Subsequently, the insect processing duration of the first batch of stacked trays sets 110A and 110E may be complete before the second or third batches are complete. The first batch ofstacked trays sets 110A and 110E can be conveniently unloaded from the second end B without having to move the second or third batches of stacked trays sets 11 OB, 110C, 110E, and 110F. The dual-access housing 102 having openable first end A and openable second end B can allow for a convenient, first-in-first-out system. Further, with sensors in individual trays 110, each batch can be monitored independently. Components of the HVAC assembly 214 and / or lighting 216 can be controlled to optimize the insect processing duration of the batches.
