Description

[Technical field]

[0001] The present invention relates to a waste paper management system and a waste paper management method. [Background technology]

[0002] Recycling of waste paper has been practiced for some time. In many cases, recycled waste paper is paper or cardboard with a recycling mark attached, generated by households and businesses. Such waste paper is clearly marked as eligible for collection by a recycling mark or the like, and collection routes are also established, including set collection dates and locations. Such waste paper is mainly recycled as a raw material for making recycled paper. For example, there is a recycling system that obtains raw material for making paper from waste paper (for example, Patent Document 1). On the other hand, there is waste paper that is difficult to use as a raw material for papermaking (difficult to recycle waste paper or hard-to-recycle waste paper). For example, difficult-to-recycle waste paper includes shredded paper, carbonless paper, sticker mounts, thermal paper, paper cups, laminated paper, foil-stamped paper containers, and wraps. For example, shredded paper is difficult to use as a raw material for papermaking because of its short fibers. Other difficult-to-recycle waste paper is processed with resins, special dyes, metals, etc. to give it functionality, and since the functional parts that have been added must be removed, it is not easy to use it as a raw material for papermaking. In this way, difficult-to-recycle waste paper is difficult to recycle. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2002-092268 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, the recycling system for hard-to-recycle wastepaper is not necessarily fully established, making it difficult to collect hard-to-recycle wastepaper at collection points, and the amount of collected wastepaper is prone to fluctuate depending on market conditions. This makes it difficult to utilize hard-to-recycle wastepaper.

[0005] The present invention has been made in consideration of the above circumstances, and its purpose is to provide a waste paper management system and a waste paper management method that can facilitate the utilization of waste paper for which collection systems are not necessarily in place. [Means for solving the problem]

[0006] In order to solve the above-mentioned problems, one aspect of the present invention is a waste paper management system that has a storage volume actual memory unit that stores storage volume actual information representing the amount of collected waste paper stored at a collection center for each different collection center, and a forecast plan generation unit that generates a waste paper stock forecast plan by calculating the future stock amount of the waste paper to be transported from each collection center to a hub base and stored there, based on the storage volume actual information stored in the storage volume actual memory unit.

[0007] Another aspect of the present invention is a waste paper management method executed by a computer, which generates a waste paper stock forecast plan by determining the future stock amount of waste paper to be transported and stored at a hub base from each collection base based on the base collection results stored in a storage amount result memory unit that stores, for each different collection base, storage amount results indicating the amount of collected waste paper stored at the collection base. Effect of the Invention

[0008] As described above, according to the present invention, it is possible to facilitate the utilization of waste paper even if a recovery system is not necessarily in place. [Brief description of the drawings]

[0010] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A used paper management system according to an embodiment of the present invention will now be described with reference to the drawings. FIG. 1 is a schematic diagram showing the concept of a used paper management system S according to an embodiment of the present invention. This wastepaper management system S can manage the distribution of wastepaper for recycling by collecting wastepaper and producing bioethanol and the like from the collected wastepaper. In this embodiment, the object of collection is wastepaper. Wastepaper can be divided into papermaking wastepaper, which is wastepaper that is easily used as a papermaking raw material, and difficult-to-recycle wastepaper (sometimes also called difficult wastepaper), which is not easily used as a papermaking raw material.

[0011] As mentioned above, there are various types of hard-to-recycle waste paper, such as shredded paper, carbonless paper, sticker paper, thermal paper, paper cups, laminated paper, foil-stamped paper containers, and wraps. The types represent the classifications that are used to visually check the waste paper when it is discharged.

[0012] In addition, in the waste paper management system S, when waste paper to be collected is classified from the viewpoint of the place of generation and the collection route, it can be roughly divided into two types: industrial waste paper and municipal waste paper. Industrial waste paper is paper that is generated during the production of products (printed matter or paper containers) and is not used as a product, such as broken paper, and is discharged from business establishments such as printing factories and paper container factories. City waste paper is generated in the city from office buildings, commercial facilities, local governments, etc., and includes, for example, paper cups, receipts using thermal paper, etc.

[0013] When industrial waste paper is generated at a business, it is stored at the business's storage facility for a certain period of time, and when it is time to collect it, it is collected by a collection company and stored in a storage facility owned by the collection company. After being stored in the collection company's storage facility for a certain period of time, the collection company transports the waste paper stored in the storage facility to a hub base. Such industrial waste paper may be transported from the business to the hub without being temporarily stored at a collection site, or may be stored at a collection company's storage site and then transported to a storage company's storage site and stored there again before being transported to the hub. Companies that collect and store waste paper are sometimes called waste paper dealers.

[0014] When the predetermined collection date and time arrives, the waste paper generated in the city is collected from the source by a collection company and stored in a storage area owned by the collection company. After being stored in the collection company's storage area for a certain period of time, the collection company transports the waste paper stored in the storage area to a hub base. Such city-generated waste paper may be transported from a business establishment to a hub location without being temporarily stored at a collection center, or it may be stored in the storage facility of a collection company, then transported to the storage facility of a storage company and stored there again, before being transported to the hub location.

[0015] The hub base temporarily stores waste paper collected from different collection bases and delivers the waste paper to the waste paper processing plant as the destination. The hub base is a facility that temporarily accumulates and stores waste paper procured (collected) for the purpose of recycling from multiple collection points (disposers and waste paper dealers).The hub base also monitors the collection status of waste paper at multiple collection points (disposers and waste paper dealers) and the storage status of the waste paper stored by the collectors, and systematically ships the waste paper to waste paper processing plants.

[0016] Here, some difficult-to-recycle wastepaper requires pre-processing in order to be recycled. The difficult-to-recycle wastepaper undergoes different pre-processing depending on the type before being generated as recycled material. At the hub base, the difficult-to-recycle wastepaper is classified by type and stored. Also, some types can be pre-processed in the same way. For example, difficult-to-recycle wastepaper types A and B can be pre-processed in the same way, but type C requires a different pre-processing, and the contents of the pre-processing process differ depending on the type. In this way, by storing the difficult-to-recycle wastepaper by type or by classification according to the processing conditions, the hub base can prevent the difficult-to-recycle wastepaper types from being delivered to the wastepaper processing plant in a mixed state. This allows for smooth and efficient recycling processing.

[0017] A waste paper processing plant is a plant that produces recycled materials by recycling waste paper. A waste paper processing plant is a plant that produces recycled materials from waste paper. For example, a waste paper processing plant may be a plant that performs at least one of the following processes: a process of producing raw materials for producing bioethanol from waste paper, a process of producing materials for producing recycled paper from waste paper, and a process of producing materials for solid fuel (RPF: Refuse derived paper and plastics densified fuel) from waste paper.

[0018] In such a waste paper management system S, waste paper may be collected from at least one of industrial waste paper and municipal waste paper.

[0019] FIG. 2 is a schematic system configuration diagram showing the configuration of the used paper management system S. As shown in FIG. In the used paper management system S, a plurality of terminal devices and a used paper management device 200 are connected via a network N so as to be able to communicate with each other. The multiple terminal devices include terminal devices used at the source of waste paper generation, terminal devices used by waste paper dealers, a hub base terminal 100, and a waste paper processing plant terminal 300. Terminal devices used at the source of waste paper include, for example, a printing factory terminal 10, a paper carton factory terminal 20, a commercial facility terminal 30, and a local government terminal 40. These terminal devices may be any of a PC (Personal Computer), a smartphone, a tablet, etc. The printing factory terminal 10 is a terminal device used in a printing factory that prints print media. The paper carton factory terminal 20 is a terminal device used in a factory that produces paper cartons. The commercial facility terminal 30 is a terminal device used in a commercial facility. Commercial facilities include, for example, department stores, train stations, public facilities, etc. The local government terminal 40 is a terminal device used in a local government, etc.

[0020] Terminal devices used in used paper dealers include, for example, a collector terminal 50a, a collector terminal 50b, a collector terminal 50c, and a collector terminal 50d (hereinafter, when not specifically identified, they may simply be referred to as collector terminals 50).

[0021] Here, there are multiple bases for collecting waste paper, such as collection base W, collection base X, collection base Y, and collection base Z. Collection base W includes a printing factory, which uses a printing factory terminal 10 and a collection company terminal 50a. Collection base X includes a paper container factory, which uses a paper container factory terminal 20 and a collection company terminal 50b. Collection base Y includes a commercial facility, which uses a commercial facility terminal 30 and a collection company terminal 50c. Collection base Z includes a local government or the like, which uses a government terminal 40 and a collection company terminal 50d.

[0022] Here, collection sites W and Y belong to group G1 where industrial wastepaper is disposed, and collection sites Y and Z belong to group G2 where municipal wastepaper is disposed.

[0023] The hub base terminal 100 is a terminal device used at a hub base. The waste paper processing plant terminal 300 is a terminal device used at a waste paper processing plant.

[0024] The used paper management device 200 receives data from each terminal device via the network N, and transmits various data to the terminal devices via the network N.

[0025] FIG. 3 is a flow chart for explaining the overall information flow of the used paper management system S. <Disposal point, waste paper dealer> A wastepaper collector or a wastepaper dealer at a wastepaper discharge site transmits wastepaper accumulation information indicating the wastepaper accumulation status from a terminal device to the wastepaper management device 200 (step S101). The wastepaper accumulation information includes, for example, the type of wastepaper, the accumulated amount, and the date. The wastepaper accumulation information may also include the type of wastepaper. The base generator is, for example, a printing factory, and an operator at the printing factory checks the wastepaper accumulation status in the printing factory and inputs wastepaper accumulation information corresponding to the accumulation status from the printing factory terminal 10 via any input device such as a keyboard, mouse, or touch panel. Alternatively, wastepaper is managed by the bale or by weight, and the printing factory terminal 10 automatically acquires the accumulation information and uses it as wastepaper accumulation information. In this way, the printing factory terminal 10 transmits wastepaper accumulation information corresponding to the wastepaper accumulation status of the printing factory to the wastepaper management device 200. Here, we will explain the case where the base generator is a printing factory, but if the base generator is a paper container factory, an operator at the paper container factory checks the accumulation status at the paper container factory and inputs waste paper accumulation information corresponding to the accumulation status from an input device of the paper container factory terminal 20. As a result, the paper container factory terminal 20 transmits waste paper accumulation information corresponding to the accumulation status of waste paper at the paper container factory to the waste paper management device 200. The base generator may be a commercial facility or a local government. In this case, similarly, waste paper accumulation information is input by an operator of a commercial facility, and transmitted from the commercial facility terminal 30 to the waste paper management device 200, and waste paper accumulation information is input by an operator of a local government, and transmitted from the local government terminal 40 to the waste paper management device 200. The waste paper accumulation information is transmitted from each terminal device of the base disposer at regular intervals, for example. In addition, waste paper dealers may temporarily store waste paper collected from collection points, etc. The waste paper dealer inputs waste paper accumulation information according to the waste paper storage status from a terminal device of the waste paper dealer. As a result, the waste paper accumulation information is transmitted from the terminal device of the waste paper dealer to the waste paper management device 200. In this manner, the used paper management device 200 can collect used paper accumulation information from site dischargers at the discharge site.

[0026] Salvage Base The collection and transportation company at the collection base transmits collection and transportation plan information, which indicates a transportation plan for the collection and transportation vehicle, from a terminal device to the waste paper management device 200 (step S102). The collection and transportation plan information includes, for example, a transportation plan such as the route (area) that each collection and transportation vehicle will travel (circulate), the discharge base to be visited for collection, the storage location, and the scheduled collection date and time. The collection and transportation plan information may also include the type of waste paper.

[0027] The collection and transportation company is, for example, a waste paper recycling company, and the operator of the collection company inputs the waste paper transportation plan drawn up by the collection company through any input device such as a keyboard, mouse, or touch panel to the collection company terminal 50. Alternatively, waste paper may be managed by bale or by weight, and the collection company terminal 50 may automatically obtain accumulation information. In this way, the collection company terminal 50 transmits the transportation plan information to the waste paper management device 200. Here, the collection company has a set area for collection, and visits the waste paper collection points or storage points in that area to collect waste paper. In some cases, the collection company periodically visits the waste paper collection point to collect the waste paper, but in other cases, when a certain amount of waste paper has accumulated at the collection point, the collection point and the collection point communicate with each other to decide the collection time.

[0028] Hub The administrator of the hub base transmits waste paper storage information from the hub base terminal 100 to the waste paper management device 200 (step S103). The waste paper storage information is, for example, information that indicates the storage status of waste paper stored at the hub base, and includes, for example, the storage location of the waste paper, the type of stored waste paper, the amount of stock stored, the storage condition, etc. The storage condition includes the moisture content, the presence or absence of dirt, the degree of dirt, the type of dirt, etc.

[0029] Shipping and transportation base The shipping and transportation company at the shipping and transportation base transmits shipping and transportation plan information representing the shipping and transportation company's transportation plan from a terminal device to the waste paper management device 200 (step S104). The shipping and transportation plan information includes, for example, the route (area) that each shipping and transportation vehicle will travel (circulate), the location of the waste paper processing plant to which the paper will be shipped, the amount of waste paper to be shipped, the type of waste paper to be shipped, and the scheduled date and time of transportation.

[0030] The operator of the shipping and transportation company inputs the shipping and transportation plan drawn up by the shipping and transportation company into the terminal device used by the shipping and transportation company via any input device such as a keyboard, mouse, touch panel, etc. In response to this, the terminal device of the shipping and transportation company transmits the shipping and transportation plan information to the waste paper management device 200. Here, the shipping and transportation company may be the same company as the collection and transportation company. The shipping and transportation plan may be input as a forecast showing when and how much waste paper can be transported from the hub base to the waste paper processing plant.

[0031] <Wastepaper management device> The used paper management device 200 performs various processes based on the information obtained from each terminal device, and transmits various information to the terminal device based on the results of the processes. For example, the waste paper management device 200 transmits a medium- to long-term stock instruction to a terminal device at a waste paper disposal site and a terminal device at a waste paper dealer (step S151). The medium- to long-term stock instruction is information that indicates a target amount of waste paper to be collected in the medium to long term. When waste paper is actually transported from a waste paper disposal point or waste paper dealer to a hub location, the waste paper management device 200 generates certificate data to certify to the waste paper disposal point or waste paper dealer that recycled materials have been produced using the collected waste paper, and can also transmit the certificate data to a terminal device of the waste paper disposal point or waste paper dealer where the waste paper originated. The wastepaper management device 200 also transmits a wastepaper collection instruction to the collection company terminal 50 (step S152). The wastepaper collection instruction is information that indicates a target amount of wastepaper to be collected in the medium to long term. The wastepaper collection instruction is information that includes the route for transporting the wastepaper from the wastepaper source, wastepaper dealer, etc. to the collection base, the target amount to be transported, the transportation date, etc. The wastepaper management device 200 generates the wastepaper collection instruction based on a stock forecast plan. The stock forecast plan includes the type of wastepaper, the target amount of wastepaper to be stored at the collection base, and the storage time, and the wastepaper management device 200 generates a wastepaper collection instruction by generating a plan (load capacity of the vehicle to be used, number of vehicles required for transportation, transportation time, etc.) for collecting wastepaper from the wastepaper source or wastepaper dealer, etc. so as to meet the storage amount by the storage time, and transporting it to the collection base. The wastepaper management device 200 also transmits a wastepaper stock forecast plan, a medium- to long-term stock instruction, and a wastepaper shipping plan to the hub base terminal 100 (step S153). The wastepaper stock forecast plan is information that processes accumulated information obtained from collection bases and expresses a target amount of wastepaper to be stored in the medium to long term as a plan. The wastepaper shipping plan is information that includes shipping plan values ​​that indicate the type of wastepaper and the shipping amount of wastepaper.

[0032] The wastepaper management device 200 also transmits a wastepaper shipping and transportation instruction, which is a plan for transporting wastepaper from the hub base to the wastepaper processing plant, to the collector terminal 50 of the shipping and transportation company (step S154). The wastepaper shipping and transportation instruction is information including the route for transporting the wastepaper from the hub base to the wastepaper processing plant, the target amount to be transported, the transportation date, etc. The wastepaper management device 200 generates the wastepaper shipping and transportation instruction based on the shipping plan. The wastepaper management device 200 generates the wastepaper shipping and transportation instruction by generating a transportation plan (load capacity of the vehicle to be used, number of vehicles required for transportation, transportation time, etc.) for the type of wastepaper indicated in the shipping plan and for satisfying the shipping plan values ​​by the shipping time. Moreover, the waste paper management device 200 transmits the waste paper stock forecast plan and the waste paper shipping plan to the waste paper processing plant terminal 300 (step S155).

[0033] Next, the functions of the used paper management device 200 will be described. FIG. 4 is a schematic block diagram showing the functions of the used paper management device 200. As shown in FIG. The waste paper management device 200 has a communication unit 201, a memory unit 202, a data acquisition unit 203, a calculation unit 204, a forecast plan generation unit 205, a stock instruction generation unit 206, a waste paper stock forecast plan transmission unit 207, a shipping plan generation unit 208, a shipping plan transmission unit 209, and a control unit 210.

[0034] The communication unit 201, data acquisition unit 203, aggregation unit 204, forecast plan generation unit 205, stock instruction generation unit 206, waste paper stock forecast plan transmission unit 207, shipping plan generation unit 208, shipping plan transmission unit 209, and control unit 210 may be composed of a processing device such as a CPU (central processing unit) or a dedicated electronic circuit.

[0035] The memory unit 202 is configured with a storage medium, for example, a hard disk drive (HDD), a flash memory, an electrically erasable programmable read only memory (EEPROM), a random access read / write memory (RAM), a read only memory (ROM), or any combination of these storage media. The storage unit 202 may be, for example, a non-volatile memory.

[0036] The communication unit 201 communicates with each terminal device via the network N. The storage unit 202 stores various data. The storage unit 202 includes a storage amount actual result storage unit 2021 and a classification storage unit 2022.

[0037] The storage amount record storage unit 2021 stores, for each collection base, a storage amount record that indicates the amount of waste paper collected at a plurality of different collection bases. The storage amount record may be the amount of waste paper discharged from a discharge base and transported to a hub base, or the amount of waste paper stored in a waste paper dealer's storage location and transported to a hub base. The storage amount record includes the type of waste paper and the amount of collected waste paper stored.

[0038] The classification storage unit 2022 stores the type of waste paper in association with a classification indicating a type that can be used in a production process for generating recycled materials from waste paper. Here, the waste paper collected from the collection base includes difficult-to-recycle waste paper, and the difficult-to-recycle waste paper can be divided into multiple different types. FIG. 5 is a diagram showing an example of the category data stored in the category storage unit 2022. As shown in FIG. The classification data is data that corresponds to the classification of waste paper (waste paper type). For example, it is shown that the waste paper type "Type A" corresponds to the classification "D1", and the types "Type D" and "Type E" correspond to the classification "D4". This indicates that the type "Type A" is recycled in a production process corresponding to the classification "D1", and that since the types "Type D" and "Type E" are in the classification "D4", there is no problem in putting them together in a production process corresponding to "D4".

[0039] The data acquisition unit 203 acquires data transmitted from each terminal device via the communication unit 201. As data obtained from the terminal devices, for example, the data acquisition unit 203 acquires waste paper accumulation information from the printing factory terminal 10, the paper container factory terminal 20, and the terminal device of the waste paper dealer. The data acquisition unit 203 also acquires transportation plan information from the collection company terminal 50, waste paper storage information from the hub base terminal 100, shipping and transportation plan information from the terminal device of the shipping and transportation company, and production plan information from the waste paper processing factory terminal 300. Moreover, the data acquisition unit 203 writes the acquired data into the storage unit 202 to store it.

[0040] The counting unit 204 counts up different types of waste paper for each section based on the storage volume record for each collection base.

[0041] The forecast plan generation unit 205 generates a waste paper stock forecast plan by calculating the future stock amount of the waste paper to be transported from each collection site to a hub site and stored based on the storage volume actual data stored in the storage volume actual data memory unit 2021. Further, the forecast plan generating unit 205 generates a waste paper stock forecast plan for each category by tallying up the actual storage amount for each category based on the tallying result of the tallying unit 204 and estimating the estimated stock amount for each category.

[0042] The stock instruction generating unit 206 generates, for each collection base, a wastepaper stock forecast plan that is a target for the amount of collected wastepaper to be stored at the collection base, based on the generated wastepaper stock forecast plan.

[0043] The wastepaper stock forecast plan transmitting unit 207 transmits the generated wastepaper stock forecast plan via the communication unit 201 to a terminal device of a wastepaper processing plant that generates recycled materials from the wastepaper. The shipping plan generating unit 208 generates a shipping plan including a planned value of the amount of waste paper to be shipped to the waste paper processing plant based on the waste paper stock forecast plan. The shipping plan transmitting unit 209 transmits the shipping plan via the communication unit 201 to a terminal device in a waste paper processing plant that produces recycled materials from waste paper. The control unit 210 controls each part of the used paper management device 200 .

[0044] Next, the operation of the waste paper management system S will be described. FIG. 6 is a flow chart for explaining the operation of the used paper management system S. The data acquisition unit 203 of the waste paper management device 200 acquires storage amount actual information for each base from a terminal device (for example, the collection company terminal 50a, collection company terminal 50b, collection company terminal 50c, collection company terminal 50d, a terminal device of a waste paper dealer, etc.) (step S201), and stores it in the storage amount actual storage unit 2021 (step S202). For a collection company, this storage amount actual information is the amount of waste paper temporarily stored at the base of the collection company by the collection company that collected the waste paper. For a hub base, the storage amount actual information is the amount of waste paper collected by each collection company, transported to the base by the collection company, and stored at the hub base. The storage amount actual information can be obtained by measuring the amount brought into the storage location by type when storing waste paper, and by measuring the amount taken out of the storage location by type. The obtained storage amount for each type is then input by the operator via an input device such as a keyboard, mouse, or touch panel. The input storage amount for each type is stored in the terminal device as storage performance information, and then transmitted to the used paper management device 200. The data acquisition unit 203 stores such storage amount result information in the storage amount result storage unit 2021 every time the data acquisition unit 203 acquires such storage amount result information from any of the terminal devices at the collection base.

[0045] When the storage amount performance information is stored, the tallying unit 204 generates storage amount performance information by tallying for each tallying period and for each type of waste paper, and stores the information in the memory unit 202. This storage amount performance information represents the actual storage amount of waste paper at the hub base. FIG. 7 is a diagram showing an example of the storage amount actual data stored in the storage amount actual data storage unit 2021. As shown in FIG. The storage volume actual information includes waste paper type, collection base, and storage volume actual value. Waste paper type indicates the type of waste paper. Collection base indicates the base where waste paper is collected. Storage volume actual value is actual value by period. The period may be any period, but examples are the year before last (Ya), the previous year (Yb), and the current year (Yc). Here, for example, waste paper type "Type A" is collected at collection base "W", and the actual monthly average in "Ya" is "800kg", "900kg" in "Yb", and "750kg" in April, "800kg" in "Yc" and "850kg" in September (present). Also, for example, waste paper type "Type c" is collected at collection center "Y" and collection center "Z." The actual collection amount at center "Y" is "500kg" on a monthly average in "Ya" and "400kg" on a monthly average in "Yb," and "350kg" in April, ..., August, and "300kg" in September (present) of "Yc." The actual collection amount at center "Z" is "50kg" on a monthly average in "Ya" and "50kg" in "Yb," and "50kg" in April, ..., August, and "50kg" in "Yc."

[0046] The tallying unit 204 generates storage volume performance information by tallying up the storage volume performance information for each type of waste paper and for each collection base for a certain period (here, for each fiscal year). Since storage volume performance information is generated for each certain period of time, it is possible to grasp the trend of storage volume based on past collection results.

[0047] Next, the forecast plan generating unit 205 generates a waste paper stock forecast plan based on the storage amount performance information collected by the collecting unit 204 (step S203). FIG. 8 is a diagram showing an example in which a waste paper stock forecast plan is generated. The forecast plan generation unit 205 generates a waste paper stock forecast plan by calculating the future stock amount (estimated stock amount) of waste paper to be transported from each collection site to a hub site and stored based on the storage volume actual data stored in the storage volume actual data memory unit 2021. Here, the waste paper stock forecast plan is stored in association with storage amount actual data. For collection base "W" for waste paper type "Type a", the forecast plan generating unit 205 estimates the future storage volume (for example, December of "Yc" year) as "800 kg" by calculating the average of the monthly average storage volume performance in "Ya" year, the monthly average storage volume performance in "Yb" year, and the storage volume performance from April to September (present) of "Yc" year. Here, the future storage volume is estimated by calculating the average value for each year, but it may be estimated by other methods, for example, the average value for the same month in the past may be calculated, or it may be calculated by a weighted average.

[0048] In this figure, the waste paper stock forecast plan includes an estimated value of the storage amount at a certain time in the future for each type of waste paper. Here, for the collection base "W" of waste paper type "a", the estimated value of the storage amount for a future month (e.g., December) of "Year Yc" is "800 kg", for the collection base "X" of waste paper type "b", the estimated value of the storage amount for a future month (e.g., December) of "Year Yc" is "250 kg", and for the combined collection base "Y" and collection base "Z" of waste paper type "c", the estimated value of the storage amount for a future month (e.g., December) of "Year Yc" is "200 kg", and these are stored in the memory unit 202.

[0049] Here, the wastepaper stock forecast plan transmission unit 207 may transmit the generated wastepaper stock forecast plan to the wastepaper processing plant terminal 300 (step S204). By transmitting the wastepaper stock forecast plan to the wastepaper processing plant terminal 300, the manager of the wastepaper processing plant can grasp the future storage amount of wastepaper by type at the hub base, so that the wastepaper processing plant itself does not need to grasp the collection status of each individual collection base, and can predict the wastepaper that can be received in the future by type. This allows production plans to be considered at an early stage.

[0050] When the wastepaper stock forecast plan is generated by the forecast plan generating unit 205, the stock instruction generating unit 206 generates wastepaper stock plan instruction information based on the generated wastepaper stock forecast plan (step S205). FIG. 9 is a diagram showing an example of used paper stock plan instruction information. The wastepaper stock plan instruction information includes the wastepaper type, the collection base, and the future stock instruction amount. The future stock instruction amount is a target value indicating how much of each type of wastepaper is to be stored at each base for the future month estimated in the wastepaper stock forecast plan. Here, the stock instruction amount is calculated based on the wastepaper stock forecast plan, so that a target that can be realized can be determined based on past trends. Here, the stock instruction generating unit 206 may use the estimated value of the stock amount obtained as the wastepaper stock forecast plan as it is as the stock instruction amount, or may calculate the stock instruction amount by multiplying the estimated value of the stock amount obtained as the wastepaper stock forecast plan by a correction coefficient according to the production trends of the wastepaper discharge base such as a factory, trends in the city, etc.

[0051] The control unit 210 transmits the generated waste paper stock plan instruction information to the terminal device of the corresponding collection base via the communication unit 201 (step S206). For example, information indicating that the December stock instruction amount of waste paper type "a" is "800 kg" is transmitted to the terminal device of collection base "W". Here, future stock instruction amounts can be notified to collection centers in advance, so each collection center can know how much of each type of waste paper they should collect and store at their own collection center. Then, waste paper can be collected and stored according to the stock instruction amount, and transported to the hub center according to the month indicated by the stock instruction amount. This makes it easier for collection centers to plan their collection activities.

[0052] When the month for which the stock amount was estimated in the wastepaper stock forecast plan (here, December as an example) arrives, the operator of each collection base inputs the actual amount of wastepaper stored at the collection base to which he or she belongs from a terminal device. For example, a collection agent at a collection base inputs the actual amount of wastepaper stored in the collection agent terminal 50, and an operator at a hub base inputs the actual amount of wastepaper stored in the hub base terminal 100. As a result, each terminal device transmits the actual amount of wastepaper stored to the wastepaper management device 200 as stock amount actual information.

[0053] The data acquiring unit 203 acquires, for each collection base, stock amount performance information transmitted from the terminal device of each collection base for the current month (here, December) (step S207), and writes the information in the storage unit 202 (step S208). FIG. 10 is a diagram showing an example of storage performance information (stock amount performance information) acquired in the current month. The storage performance information includes waste paper type, collection base, stock performance for the current month (December in this case), and inventory amount. The stock performance for the current month indicates the amount of waste paper transported from the collection base to the hub base in the current month. The inventory amount indicates the amount of each type of waste paper stored as inventory at the hub base. This inventory is collected from each collection base, temporarily stored at the hub base, and then shipped to the waste paper processing plant when the shipping timing arrives, but of the stored amount, some is not shipped and is kept as inventory. Here, as an example, it is shown that there is 100 kg of waste paper type "a" collected from collection base "W" and stored in inventory.

[0054] The shipping plan generating unit 208 generates a shipping plan including a planned value of the amount of waste paper stored in the hub base to be shipped to the waste paper processing plant based on the waste paper stock forecast plan (step S209). FIG. 11 is a diagram illustrating an example of a shipping plan. The shipping plan includes the type of waste paper and the storage record amount for the period corresponding to the shipping period. As an example of the storage amount for the period corresponding to the shipping time, the storage amount for December is shown here. The shipment plan generation unit 208 may generate the shipping plan value by directly using the storage performance value indicated by the storage performance information acquired in the current month (Figure 10) as the shipping plan value, or may generate the shipping plan value by adding at least a portion of the inventory amount in the current month to the storage performance value indicated by the storage performance information acquired in the current month. In this manner, the shipment plan generating unit 208 generates the shipment plan value for each type of waste paper.

[0055] When the shipping plan value is calculated by the shipping plan generating unit 208, the shipping plan transmitting unit 209 transmits the shipping plan value to the waste paper processing plant terminal 300 (step S210). This allows the waste paper processing plant to know the amount of waste paper received in the next month.

[0056] According to the embodiment described above, a waste paper stock forecast plan can be made at the hub location, and then stock instructions can be sent to each collection location in advance regarding the amount of waste paper to be stored there, thereby reducing the burden of managing the amount of waste paper stored at each collection location. Furthermore, according to the above-described embodiment, a waste paper shipping plan for the hub base can be made based on a forecast plan established at an early stage, so that waste paper can be supplied (shipped) to waste paper processing plants in a stable manner.

[0057] According to the above-described embodiment, depending on the type of hard-to-recycle waste paper, the amount of collection may vary depending on the season, events, etc., but even in such cases, the waste paper collected at the collection point can be collected at a hub base, temporarily stored, and then shipped to the waste paper processing plant when a certain amount of waste paper has accumulated. Therefore, even if the collection amount varies depending on the market situation, the waste paper can be shipped to the waste paper processing plant stably. In this way, even waste paper, including difficult-to-recycle waste paper for which collection systems have not necessarily been fully established, will be more easily accepted by waste paper processing plants and will be able to be recycled stably, making it easier to utilize difficult-to-recycle waste paper.

[0058] In addition, when waste paper is received individually from many different collection points, the management burden increases if the collection status of the multiple collection points is managed individually to create a production plan, but the hub base can be used to consolidate waste paper and manage the collection status from each collection point, reducing the burden of waste paper receipt management. In addition, instead of receiving waste paper individually from collection points, it can be consolidate at the hub base and receive waste paper in large units, making it easier to plan production. In addition, waste paper collected from collection points can be collected at the hub base and temporarily stored before being shipped to the waste paper processing plant, so even if there are fluctuations in the collection status, the hub base can absorb the fluctuations because the stock already stored at the hub base can be used for shipping. This allows waste paper processing plants to receive a stable supply of waste paper.

[0059] In addition, although there are multiple types of difficult-to-recycle wastepaper, the difficult-to-recycle wastepaper is collected from multiple different collection points at a hub location before being shipped to the wastepaper processing plant.Therefore, even if the difficult-to-recycle wastepaper is of different types, if it belongs to the same category, it can be aggregated into one category to generate a wastepaper stock forecast plan.Therefore, by collecting wastepaper of different types to correspond to the processing unit at the wastepaper processing plant, it becomes easier to carry out the cycle processing corresponding to that category, compared to handling it as is by type. Furthermore, waste paper stock plan instruction information can be notified to each collection base, and waste paper can be collected with the waste paper stock plan instruction information as a target, so that waste paper can be collected stably.

[0060] In addition, because wastepaper processing plants can receive wastepaper from hub locations at times according to production plans, there is no need for the plants to store the wastepaper until it can be recycled.

[0061] The waste paper management device 200 in the above-mentioned embodiment may be realized by a computer. In that case, a program for realizing this function may be recorded in a computer-readable recording medium, and the program recorded in the recording medium may be read into a computer system and executed to realize the function. The term "computer system" here includes hardware such as an OS and peripheral devices. The term "computer-readable recording medium" refers to portable media such as flexible disks, optical magnetic disks, ROMs, and CD-ROMs, and storage devices such as hard disks built into a computer system. The term "computer-readable recording medium" may also include a medium that dynamically holds a program for a short period of time, such as a communication line when a program is transmitted via a network such as the Internet or a communication line such as a telephone line, and a medium that holds a program for a certain period of time, such as a volatile memory inside a computer system that is a server or client in that case. The above-mentioned program may be a program for realizing part of the above-mentioned function, or may be a program that can realize the above-mentioned function in combination with a program already recorded in the computer system, or may be a program that is realized using a programmable logic device such as an FPGA (Field Programmable Gate Array).
