[0015] [Embodiment 1] 〔overview〕 An embodiment of the present disclosure will be described in detail below. As described above, coffee is enjoyed by so many people that it is considered one of the world's three most popular beverages, and the effective reuse of coffee grounds after brewing coffee is of great social significance. Therefore, the use determination and display system 100 according to the present disclosure determines and displays the use of coffee grounds depending on the condition of the coffee grounds. By appropriately determining the use of the coffee grounds depending on their condition, the coffee grounds can be effectively utilized.

[0016] Fig. 1 shows an example of a use determination display system 100. As shown in Fig. 1, the use determination display system 100 includes a use determination device 10, a use display device 20, and a discharge information transmission device 30. For example, the discharge information transmission device 30 is disposed in a coffee shop A (store) that serves coffee, the use display device 20 is disposed in a storage warehouse B (storage location) that receives and stores coffee grounds from coffee shop A, and the use determination device 10 is disposed in a control center C that determines the use of the coffee grounds stored in storage warehouse B.

[0017] Fig. 2 shows a functional block diagram of the use determination display system 100. As shown in Fig. 2, the use determination device 10 includes an acquisition unit 11, a determination unit 12, and an output unit 13. The use display device 20 includes an acquisition unit 21, a storage information creation unit 22, a transmission unit 23, a reception unit 24, and a display unit 25. The discharge information transmission device 30 includes a reception unit 31 and a transmission unit 32.

[0018] The receiving unit 31 of the discharge information transmitting device 30 receives input of discharge information. Furthermore, the transmitting unit 32 transmits the discharge information received by the receiving unit 31 to the purpose display device 20, which is an external device. As described above, the discharge information transmitting device 30 is disposed in, for example, coffee shop A. Discharge information is input to the discharge information transmitting device 30 by a staff member or the like of coffee shop A. The discharge information is information including the coffee grounds discharge date and the amount of discharge. By inputting the discharge information, it is no longer necessary to measure the amount of coffee grounds again in storage warehouse B, where the coffee grounds are sent, thereby reducing the workload of workers.

[0019] The acquisition unit 21 of the usage display device 20 acquires the discharge information from the discharge information transmission device 30. The storage information creation unit 22 creates storage information using the discharge information acquired by the acquisition unit 21. The storage information is information indicating the storage amount and storage period of the coffee grounds stored in storage warehouse B. The storage period can be calculated from the discharge date included in the discharge information. The storage amount can be calculated from the discharge amount included in the discharge information. The storage amount and storage period may be managed in daily units; for example, if coffee grounds are discharged in three installments of 10 kg each on the same day, the storage amount is 30 kg, and the storage period is the number of days that have passed since the date of discharge.

[0020] Furthermore, the storage information creation unit 22 may create storage information in response to an instruction from the use determination device 10. Furthermore, the storage information creation unit 22 may update the created storage information according to the timing of creation. Updating the storage information according to the timing of creation means, for example, when creating storage information for 10 kg of coffee grounds discharged on January 1, the storage information created on January 2 will have a storage amount of 10 kg and a storage period of 1 day, and the storage information created on January 3 will have a storage amount of 10 kg and a storage period of 2 days.

[0021] The transmitting unit 23 transmits the storage information created by the storage information creating unit 22 to the usage determination device 10. The receiving unit 24 receives usage information indicating the usage determined by the usage determination device 10 from the usage determination device 10. The display unit 25 is a display device that displays the usage information received by the receiving unit 24. Examples of the display unit 25 include a liquid crystal display and an organic EL display.

[0022] The acquisition unit 11 of the use determination device 10 acquires storage information from the use display device 20. The determination unit 12 uses the storage information acquired by the acquisition unit 11 to determine the use of the coffee grounds. For example, the determination unit 12 may determine whether the coffee grounds should be used as a material for furniture or as an environmental improvement material in the livestock farming field. In this case, the determination unit 12 may determine that coffee grounds stored for a period longer than a predetermined threshold period should be used as an environmental improvement material, and that coffee grounds stored for a period within the predetermined period should be used as furniture. The predetermined period may vary depending on the season. That is, the predetermined period may be shorter in summer than in winter. This allows, for example, small amounts of high-quality coffee grounds to be used as furniture, and large amounts of low-quality coffee grounds to be used as an environmental improvement material. Furthermore, since the impact of the length of storage period on the coffee grounds varies depending on the season, determining the use using different storage periods depending on the season allows appropriate uses to be determined depending on the season.

[0023] Fixtures may include, for example, tableware used for meals, such as bowls, plates, cups, and drinking glasses, as well as small items and miscellaneous items that accompany tableware, such as trays and serving trays. Environmental improvement materials in the livestock farming field may include fertilizer, compost, bedding, etc. Furthermore, when environmental improvement materials include fertilizer, compost, and bedding, priority is given to bedding, and if the materials cannot be used as bedding, they may be used as fertilizer or compost.

[0024] Furthermore, the determination unit 12 may determine different uses for the same coffee grounds depending on the timing of the determination. For example, if the use of coffee grounds discarded on January 1st is determined to be material for fixtures on February 1st, but the coffee grounds are further stored, the determination unit 12 may determine the use of the coffee grounds as environmental improvement materials on June 1st.

[0025] The output unit 13 outputs to the use display device 20 use information indicating the use of the coffee grounds determined by the determination unit 12.

[0026] As described above, the use determination device 10 includes an acquisition unit 11 that acquires storage information indicating the storage period and storage amount of coffee grounds stored in the storage warehouse B. The device also includes a determination unit 12 that determines the use of the coffee grounds according to the storage period and storage amount. The device also includes an output unit 13 that outputs use information indicating the use determined by the determination unit 12. This allows the coffee grounds to be used for an appropriate purpose according to their condition, and allows the coffee grounds to be efficiently reused without being wasted. Furthermore, these effects also contribute to the achievement of, for example, Goal 12 of the Sustainable Development Goals (SDGs) advocated by the United Nations, "Ensure sustainable consumption and production patterns."

[0027] The use display device 20 also includes a transmitter 23 that transmits storage information indicating the storage period and storage amount of the coffee grounds stored in the storage warehouse B, a receiver 24 that receives use information indicating the use of the coffee grounds determined based on the storage information, and a display unit 25 that displays the use indicated by the use information. This allows the user to easily recognize the appropriate use of the coffee grounds and perform the necessary work.

[0028] The discharge information transmitting device 30 also includes a receiving unit 31 that receives input of discharge information indicating the discharge date and discharge amount for the coffee grounds discharged from coffee shop A, and a transmitting unit 32 that transmits the discharge information to the purpose display device 20. This allows the user of the purpose display device 20, which is the device that has acquired the discharge information, to easily recognize the storage period and amount of the coffee grounds.

[0029] [Example of usage information display] Figure 3 shows an example of use information displayed on the display unit 25 of the use display device 20. The example shown in Figure 3 is an example of use information 201 displayed on April 12, 2024. Here, an example is shown in which coffee grounds are used for composting as an environmental improvement material. The example of use information 201 shown in Figure 3 indicates that the use of coffee grounds, whose storage start date is April 1, 2023 and whose storage amount is 180 kg, is to be used for composting. Similarly, the following data shows that the use of coffee grounds with a storage start date of July 1, 2023 and a stored amount of 150 kg is compost, the use of coffee grounds with a storage start date of September 1, 2023 and a stored amount of 150 kg is compost, the use of coffee grounds with a storage start date of November 1, 2023 and a stored amount of 210 kg is compost, the use of coffee grounds with a storage start date of February 1, 2024 and a stored amount of 140 kg is 100 kg of fixtures and 40 kg of compost, and the use of coffee grounds with a storage start date of April 1, 2024 and a stored amount of 130 kg is 100 kg of fixtures and 30 kg of compost.

[0030] Although an example has been shown here in which the storage start date and storage amount are displayed together with the purpose, the present invention is not limited to this, and a configuration in which only the purpose is displayed may also be used.

[0031] [Processing flow in the use determination display system] Next, the flow of processing in the use determination display system 100 will be described with reference to Fig. 4. Fig. 4 is a sequence diagram showing the flow of processing in the use determination display system 100.

[0032] 4, in the use determination display system 100, first, the receiving unit 31 of the discharge information transmitting device 30 receives input of discharge information (S101, receiving step). Then, the transmitting unit 32 transmits the discharge information received by the receiving unit 31 to the use display device 20 (S102, transmitting step). Having acquired the discharge information from the discharge information transmitting device 30, the use display device 20 uses the discharge information to create storage information indicating the storage period and storage amount of the coffee grounds (S201). Then, the created storage information is transmitted to the use determination device 10 (S202, transmitting step).

[0033] When the use determination device 10 acquires storage information from the use display device 20 (S301, acquisition step), it determines the use of the coffee grounds (S302, determination step) and outputs use information indicating the determined use to the use display device 20 (S303, output step).The use display device 20 then receives the use information from the use determination device 10 (S203, reception step) and displays it on the display unit 25 (S204, display step).

[0034] The above is the flow of processing in the use determination display system 100.

[0035] [Variation 1] In the above-described use determination display system 100, a configuration has been described in which a staff member or the like at coffee shop A inputs discharge information into the discharge information transmitting device 30, but the discharge information transmitting device 30 does not necessarily have to be included. That is, the use determination display system 100 may be composed of the use determination device 10 and the use display device 20. In this case, the use display device 20 can create storage information from the date of receipt and the amount of coffee grounds stored in storage warehouse B.

[0036] Although the above description has been given using coffee grounds as an example of an object for which a use is to be determined, the object for which a use is to be determined is not limited to coffee grounds. That is, the use determination display system 100 according to the present disclosure can be applied to residues of various beverages. Furthermore, it can also be applied to residues of liquids other than beverages.

[0037] [Embodiment 2] Other embodiments of the present invention will be described below. For ease of explanation, the same reference numerals will be used to designate components having the same functions as those described in the above embodiment, and the description thereof will not be repeated.

[0038] In the above-described first embodiment, a configuration has been described in which the discharge information inputted by the discharge information transmitting device 30 is transmitted to the use display device 20. In the present embodiment, a configuration will be described in which the discharge information is transmitted to the use determining device 10A.

[0039] Fig. 5 shows an example of a use determination display system 100A according to this embodiment. As shown in Fig. 5, the use determination display system 100A includes a use determination device 10A, a use display device 20A, and a discharge information transmission device 30A. As with the use determination display system 100 described in the first embodiment above, for example, the discharge information transmission device 30A is disposed in a coffee shop A that serves coffee, the use display device 20A is disposed in a storage warehouse B that receives and stores coffee grounds from the coffee shop A, and the use determination device 10A is disposed in a control center C that determines the use of the coffee grounds stored in the storage warehouse B.

[0040] Fig. 6 shows a functional block diagram of the use determination display system 100A. As shown in Fig. 2, the use determination device 10A includes an acquisition unit 14, a storage information creation unit 15, a determination unit 12, and an output unit 13. The use display device 20A includes a reception unit 24 and a display unit 25. The discharge information transmission device 30A includes a reception unit 31 and a transmission unit 32.

[0041] The receiving unit 31 of the discharge information transmitting device 30A receives input of discharge information. The transmitting unit 32 transmits the discharge information received by the receiving unit 31 to the use determination device 10A, which is an external device. The destination to which the discharge information is transmitted is different from the use determination display system 100 described in the first embodiment.

[0042] The acquisition unit 14 of the use determination device 10A acquires the discharge information from the discharge information transmission device 30A. The storage information creation unit 15 creates storage information using the discharge information acquired by the acquisition unit 14. The determination unit 12 determines the use of the coffee grounds using the storage information created by the storage information creation unit 15. The output unit 13 outputs use information indicating the use of the coffee grounds determined by the determination unit 12 to the use display device 20A.

[0043] The receiving unit 24 of the usage display device 20A receives usage information indicating the usage decided by the usage deciding device 10 A from the usage deciding device 10 A. The display unit 25 displays the usage information received by the receiving unit 24.

[0044] [Processing flow in the use determination display system] Next, the flow of processing in the use determination display system 100A will be described with reference to Fig. 7. Fig. 7 is a sequence diagram showing the flow of processing in the use determination display system 100A. As shown in Fig. 7, in the use determination display system 100A, first, the receiving unit 31 of the discharge information transmitting device 30A receives input of discharge information (S401). Then, the transmitting unit 32 transmits the discharge information received by the receiving unit 31 to the use determination device 10A (S402). Having acquired the discharge information from the discharge information transmitting device 30A, the use determination device 10A uses the discharge information to create storage information indicating the storage period and storage amount of the coffee grounds (S501). Then, using the created storage information, it determines the use of the coffee grounds (S502), and outputs use information indicating the determined use to the use display device 20A (S503).

[0045] The use display device 20A receives use information from the use determining device 10A (S601) and displays it on the display unit 25 (S602).

[0046] The above is the flow of processing in the use determination display system 100A.

[0047] [Software implementation example] The functions of the use determination display system 100, 100A (hereinafter referred to as the "system") can be realized by a program that causes a computer to function as the system, and a program that causes a computer to function as each control block of the system (in particular, the determination unit 12 of the use determination device 10 and the storage information creation unit 22 of the use display device 20).

[0048] In this case, the system includes a computer having at least one control device (e.g., a processor) and at least one storage device (e.g., a memory) as hardware for executing the program. The control device and storage device execute the program, thereby realizing the functions described in each of the above embodiments.

[0049] The program may be non-transitory and may be recorded on one or more computer-readable recording media. The recording media may or may not be included in the system. In the latter case, the program may be supplied to the device via any wired or wireless transmission medium.

[0050] Furthermore, some or all of the functions of the control blocks can be realized by logic circuits. For example, an integrated circuit in which a logic circuit that functions as each of the control blocks is formed is also included in the scope of the present invention. In addition, the functions of the control blocks can also be realized by, for example, a quantum computer.

[0051] Furthermore, each process described in each of the above embodiments may be executed by AI (Artificial Intelligence). In this case, the AI ​​may run on the control device or on another device (for example, an edge computer or a cloud server).

[0052] 〔summary〕 A use determination device according to a first aspect of the present disclosure includes an acquisition unit that acquires the storage period and storage amount of coffee grounds stored in a storage location, a determination unit that determines a use of the coffee grounds based on the storage period and storage amount, and an output unit that outputs use information indicating the use determined by the determination unit.
