The recycling date designation information is input, for example, by a manager of the algae production location, etc.

[0027] In addition, the collection DB 141 stores and manages information for each drying site (hereinafter referred to as "drying site information"). A drying site is a site having a drying facility for drying algae. The drying site information includes, for example, drying position information. The drying position information is information indicating the position of the drying site.

[0028] The communication interface 150 is an interface used by the processing device 100 to communicate via the network NW or the like.

[0029] The display device 160 displays a screen for notifying various information to the operator of the processing apparatus 100 or the like. The display device 160 is, for example, a display such as a liquid crystal display or an organic electroluminescence (EL) display.

[0031] The bus 180 includes a control bus, an address bus, and a data bus, and transmits signals sent and received between various parts of the processing device 100 .

[0032] The mobile body 200 can move, for example, under the driving of a driver, and can transport algae by the movement. The mobile body 200 is, for example, a car, a railway vehicle, a ship, or an airplane. The mobile body 200 is preferably moved by electricity. Thus, the recycling and processing system 1 can reduce the carbon dioxide emissions during the recovery and transportation of algae. In addition, when the mobile body 200 is an electric car, the mobile body 200 is, for example, an electric car. As an example, the mobile body 200 includes a control device 210, a power unit 220, and a container 230. The control device 210 can also be capable of controlling the centrifuge 300.

[0033] The control device 210 is a computer that controls each part of the mobile body 200. The control device 210 is, for example, an electronic control unit (ECU). Alternatively, the control device 210 may be an on-board computer different from the ECU.

[0034] The power unit 220 generates power for the moving body 200 to travel and power for operating the centrifuge 300. The power unit 220 has, for example, at least one of an engine and a motor.

[0035] The container 230 is a container for transporting algae. The container 230 contains algae. The container 230 may be integrated with the centrifuge 300. The centrifuge 300 may also serve as the container 230.

[0036] The centrifuge 300 is a device for separating algae liquid into algae and culture medium by centrifugation to reduce the water content of the algae liquid. By reducing the water content by the centrifuge 300, the algae liquid becomes concentrated algae. By changing from algae liquid to concentrated algae, the mass and volume are reduced. Compared with the algae liquid, the mass ratio of the concentrated algae to the whole is larger. Therefore, the cost of transporting the concentrated algae is lower than the cost of transporting the algae liquid containing the same amount of algae as that contained in the concentrated algae.

[0037] For example, the mobile body 200 includes a centrifuge 300. Alternatively, the centrifuge 300 is installed outside the mobile body 200.

[0047] The bus 580 includes a control bus, an address bus, a data bus, and the like, and transmits signals sent and received between various components of the terminal device 500 .

[0048] The recovery and processing system 1 is a system for producing algae in a plurality of production sites, and recovering, transporting, drying, and processing the algae produced in each production site. Figure 2 A method for producing algae in a plurality of production sites and recovering, transporting, drying, and recovering the algae produced in each production site (hereinafter referred to as a “recovery method”) will be described. Figure 2 This is a flowchart showing an example of the recycling method according to the embodiment.

[0049] Figure 2 Step ST1 of the embodiment represents a production process. The production process is a process of producing algae at a production site. The production site produces algae by, for example, cultivating algae in a cultivation device containing a culture solution and algae.

[0050] Step ST2 represents a centrifugal separation process. The centrifugal separation process is a process of obtaining concentrated algae by reducing the water content of the algae liquid using the centrifuge 300. The driver of the mobile body 200 drives the mobile body to the recovery site. When the centrifuge 300 located outside the mobile body 200 is used, and when the centrifuge 300 is operated by the power of the power unit 220, the driver or the person in charge connects the mobile body 200 and the centrifuge 300 with the power transmission device 400. The driver or the person in charge loads the algae liquid at the recovery site into the centrifuge 300. Then, the driver or the person in charge makes the algae liquid into concentrated algae by operating the centrifuge 300. After that, the driver or the person in charge loads the concentrated algae into the container 230. In addition, the culture solution separated by the centrifuge 300 is preferably reused for the cultivation of algae. The driver or the person in charge loads the culture solution separated by the centrifuge 300 into a container in the production site, which is used to load the culture solution for reuse. When the culture solution is reused, it is preferred to adjust the composition before reuse.

[0051] The driver drives the mobile body 200 to patrol a plurality of predetermined collection locations, and performs the centrifugal separation process at each collection location. At this time, the driver patrols according to the patrol route displayed on the display device 560, for example.

[0052] Step ST3 represents a first transport process. The first transport process is a process of transporting concentrated algae collected at a plurality of collection sites to a drying site using the mobile body 200. A drying site is a site having drying equipment for drying algae. A drying site is a facility having equipment for drying algae. A drying site is, for example, a service center where algae can be brought in for drying. The driver drives the mobile body 200, for example, according to the patrol route displayed on the display device 560, and transports the concentrated algae to the designated drying site.

[0053] Step ST4 represents a drying process. The drying process is a process of drying the concentrated algae to make a dry powder. The driver or the person in charge puts the concentrated algae in the container 230 into the drying device. Then, the driver or the person in charge operates the drying device to make the concentrated algae into a dry powder.

[0054] Step ST5 represents the second conveying process. The second conveying process is a process for conveying dry powder to a processing site where algae is processed. The processing site is, for example, a processing plant that processes algae into commodities such as fuel, structures, materials, food, feed, cosmetics or medicines. The mobile body used for conveying dry powder in the second conveying process may also be a mobile body other than the mobile body 200. In addition, when the mobile body 200 is used in the second conveying process, it may be the same mobile body as the mobile body 200 used in the first conveying process, or it may be different. In addition, the dry powder conveyed in the second conveying process may also be a powder that has been dried through multiple steps ST2 to ST4. The driver or person in charge of the mobile body stores the dry powder in the drying site into the mobile body. Then, the driver drives the mobile body to convey the dry powder to a predetermined processing site. Then, the driver or person in charge of the mobile body loads the dry powder in the mobile body into a storage container for dry powder in the processing site.

[0055] Step ST6 represents a processing step. The processing step is a step of processing the dry powder conveyed in the second conveying step into a commodity such as fuel, structure, material, food, feed, cosmetics or medicine.

[0056] The following is based on Figure 3 and Figure 4 The operation of the recycling processing system 1 according to the embodiment will be described in the following. The processing contents in the following operation description are examples, and various processing that can obtain the same result can be used as appropriate. Figure 3 1 is a flowchart showing an example of processing performed by the processor 110 of the processing device 100. The processor 110 executes, for example, based on a program stored in the ROM 120 or the auxiliary storage device 140. Figure 3 processing. Figure 4 5 is a flowchart showing an example of processing performed by the processor 510 of the terminal device 500. The processor 510 executes, for example, based on a program stored in the ROM 520 or the auxiliary storage device 540. Figure 4 processing.

[0057] exist Figure 3In step ST11, the processor 110 of the processing device 100 determines whether to start the path determination process. The processor 110 determines, for example, that the path determination process is to be started when a specific time has arrived. The specific time is when a predetermined time has arrived. The processor 110 may, for example, perform the path determination process at the same time every day. In addition, the processor 110 determines that the path determination process is to be started when an input indicating that the path determination process is to be performed is received. The input is based on an operation input to the input device 170. Alternatively, the processor 110 determines that the path determination process is to be started when an input indicating that the path determination process is to be performed is received via the communication interface 150. If the processor 110 does not determine that the path determination process is to be started, it determines "No" in step ST11 and repeats the process of step ST11. In contrast, if the processor 110 determines that the path determination process is to be started, it determines "Yes" in step ST11 and enters step ST12. In addition, steps ST12 and ST13 are path determination processes.

[0058] In step ST12, the processor 110 determines the recycling site where algae are to be recycled in one patrol. To this end, the processor 110, for example, refers to the recycling DB 141 to obtain the recycling site information of each recycling site. The processor 110 uses the production volume information and the recycling date designation information in the recycling site information to obtain, for each recycling site, the amount of algae before the date or time when algae recycling is to be carried out (hereinafter referred to as "the amount of algae to be recycled"). Then, the processor 110 selects the recycling site so that the total amount obtained by adding up the amount of algae to be recycled does not exceed the amount that the mobile body 200 can transport. In addition, the processor 110, for example, tries to select in sequence from the recycling site with the earliest date or time of algae recycling among the algae produced in the recycling site. The processor 110 determines the recycling site selected in step ST12 as the recycling site where algae recycling is to be carried out in one patrol. In addition, the processor 110 can also select the recycling site by using the distance between the recycling sites.

[0059] In step ST13, the processor 110 refers to the recycling DB 141 to obtain the drying place information. The processor 101 determines the recycling patrol path using the recycling position information in the recycling place information and the drying position information in the drying place information. The recycling patrol path indicates in which order and via which path each recycling place determined as a recycling place in step ST12 is patrolled, and by which path the algae recovered during the patrol is transported to which drying place. The processor 110, for example, determines the recycling patrol path with the smallest moving cost. The moving cost is, for example, the moving distance or the moving time. The processor 110, for example, determines the recycling patrol path based on the way to solve the traveling salesman problem. The processor 110, for example, solves the traveling salesman problem using an algorithm that obtains an approximate solution or an exact solution. In addition, the drying place for drying the algae can also be predetermined. Alternatively, the processor 110 selects the best drying place from a plurality of drying places. The best drying place is, for example, a drying place with the smallest moving cost of the first transport process. The best drying place is, for example, a drying place with the smallest sum of the moving cost of the recycling patrol path and the moving cost of the first transport process. In addition, the processor 110 may also determine the recycling location and the recycling patrol path at the same time.

[0060] As described above, the processor 110 performs the processes of step ST12 and step ST13 to function as an example of a determination unit that determines a location for collecting algae and determines the order in which the plurality of locations are patrolled to collect algae.

[0061] In step ST14, the processor 110 displays the path determined in step ST13. The display location of the path is, for example, the display device 160 or the display device 560. The processor 110 controls the display device 160 to display the path. In order to make the display device 560 display the path, the processor 110 generates path information, for example. The path information includes information indicating the path determined in step ST13. After generating the path information, the processor 110 instructs the communication interface 150 to send the path information to the terminal device 500. Upon receiving the instruction to send, the communication interface 150 sends the path information to the terminal device 500. The sent path information is received by the communication interface 550 of the terminal device 500. After processing step ST14, the processor 110 returns to step ST11.

[0062] On the other hand, Figure 4 In step ST21, the processor 510 of the terminal device 500 waits for receiving the route information via the communication interface 550. If the route information is received, the processor 510 determines "yes" in step ST21 and proceeds to step ST22.

[0063] In step ST22, the processor 510 controls the display device 560 based on the received path information so that the display device 560 displays Figure 3 The processor 510 determines the path in step ST13. Figure 4 After processing step ST22, return to step ST21.

[0064] According to the recycling processing system 1 of the embodiment, the processing device 100 determines the production site where the algae are recycled. In addition, the processing device 100 determines the order in which the production sites are patrolled and the algae are recycled. Thus, the recycling method of the embodiment that needs to recycle algae in multiple production sites can be realized. Therefore, the processing device 100 of the embodiment can reduce the cost of using algae for industrial purposes than before.

[0065] Furthermore, according to the recycling processing system 1 of the embodiment, the processing device 100 determines to which of the plurality of drying locations the algae recovered from the plurality of production locations are to be transported. Thus, the processing device 100 of the embodiment can reduce the cost of using the algae for industrial purposes by determining the optimal drying location.

[0066] Furthermore, according to the recycling processing system 1 of the embodiment, the processing device 100 determines the order in which to patrol the production site so as to minimize the movement cost. Thus, the processing device 100 of the embodiment can reduce the cost of using algae for industrial purposes.

[0067] In the recovery method of the embodiment, algae is produced at multiple production sites. In the recovery method of the embodiment, a mobile body 200 is used to patrol multiple production sites for recovery. In the recovery method of the embodiment, the algae liquid is centrifuged at the production site, and the algae separated from the algae liquid is recovered. In the recovery method of the embodiment, the algae recovered from multiple production sites are transported to a drying site and dried. The volume of the algae separated by centrifugation is smaller than that of the algae liquid. Therefore, compared with the case of recovering in the state of algae liquid, the recovery method of the embodiment can recover algae produced in more production sites at one time. In addition, the mass of the algae separated by centrifugation is smaller than that of the algae liquid. Therefore, the recovery method of the embodiment spends less fuel on transportation. Based on the above, the recovery method of the embodiment is lower than the cost spent on transportation in the past.

[0068] In addition, the recovery method of the embodiment reuses the culture solution separated by centrifugation from the algae solution. Therefore, the recovery method of the embodiment can achieve effective utilization of aquatic resources.

[0069] In addition, the recovery method of the embodiment uses the power of the power unit 220 of the mobile body 200 to operate the centrifuge 300. Therefore, the recovery method of the embodiment does not need to install a power source for the centrifuge 300 at the production site.

[0070] In addition, in the recovery method of the embodiment, the production site may also have a centrifuge 300. Since there is no need to install a power source for the centrifuge 300 at the production site, the centrifuge 300 in the recovery method of the embodiment can be simplified.

[0071] In addition, in the recovery method of the embodiment, the mobile body 200 may also include the centrifuge 300. Therefore, in the recovery method of the embodiment, it is not necessary to install the centrifuge 300 at the production site.

[0072] In addition, in the recycling method of the embodiment, the movable body 200 is an electric type. Therefore, the recycling method of the embodiment can reduce the amount of carbon dioxide emissions.

[0073] The above-mentioned embodiment may also be modified as follows.

[0074] The mobile body 200 may also be autonomously driven. In this case, the control device 210 controls the autonomous driving. In addition, the operations performed by the driver in the above-mentioned embodiment may also be performed by the control device 210 and devices controlled by the control device 210.

[0075] Each device in the embodiment may be composed of a plurality of devices.

[0076] The processor 110 or the processor 510 may be configured by circuit hardware to implement part or all of the processing implemented by a program in the above-mentioned embodiments.

[0077] The program for implementing the processing of the embodiment is transferred, for example, in a state where it is stored in a non-transitory computer-readable storage medium in the device. However, the program can also be transferred when the device does not store the program. Then, the program can also be transferred separately and written into the device. The transfer of the program in this case can be achieved, for example, by recording it in a removable non-transitory computer-readable storage medium or downloading it via a network such as the Internet or a local area network (LAN).

[0078] The embodiments of the present invention have been described above, but these are merely examples and do not limit the scope of the present invention. The embodiments of the present invention can be implemented in various forms without departing from the spirit of the present invention.
