When paper curing board is incinerated together with other industrial waste, carbon dioxide is generated. Therefore, there is a demand to suppress carbon dioxide generation from paper curing board as well.

[0005] Therefore, an object of the present invention is to provide a method for recycling paper curing boards that can reduce carbon dioxide emissions, a recycled paper curing board, and a recycling system for paper curing boards. [Means for solving the problem]

[0006] A first invention relates to a method for recycling paper curing boards, which includes a manufacturing process for manufacturing the paper curing boards from rolled paper, a delivery process for delivering the paper curing boards manufactured in the manufacturing process to users, a collection request process for the users to request collection of the paper curing boards delivered in the delivery process, a recovery process for a recovery company to recover the paper curing boards from the users based on the collection request made in the collection request process, and a pulp recycling plant where the paper curing boards recovered in the recovery process are dissolved into fibers and recycled into pulp raw material. and a papermaking process in which roll paper to be used in the manufacturing process is produced at a paper mill from the pulp raw material recycled in the recycling process. In the delivery process, a collection request medium for requesting the collection of the paper curing board is handed to the user. In the collection request process, the user uses the collection request medium to send information about the collection location of the paper curing board to the collection company via a communication device connected to a communication line, requesting collection. In the collection process, a collection route is set in accordance with the collection request in the collection request process, and the paper curing board is collected in accordance with the set collection route.

[0007] According to the present invention, in the delivery process, a collection request medium related to the collection request is handed over to the user, and in the collection request process, the user uses the collection request medium to transmit information regarding the collection location via a communication device to request collection. Then, in the collection process, a collection route is set in accordance with the collection request in the collection request process, and the paper curing board is collected according to the set collection route. That is, collection is requested based on the request via the collection request medium, and the paper curing board is collected. Therefore, since the user can be encouraged to collect and recycle the paper curing board at the time of delivery, the paper curing board can be prevented from being incinerated together with industrial waste, thereby reducing carbon dioxide emissions.

[0008] In the above invention, the paper curing board is preferably a corrugated cardboard board having a liner and a corrugated core.

[0016] In the above invention, in the collection step, if there are a plurality of collection locations, it is preferable that the computer automatically sets a collection route based on the plurality of collection locations.

[0017] According to the above configuration, when there are multiple collection locations, the computer automatically sets the collection route based on the multiple collection locations, making it possible to easily and efficiently set the collection route.

[0018] In the above invention, it is preferable that in the delivery step, the collection request medium is handed over to the user together with the paper protective board that has been sold.

[0019] According to the above configuration, in the delivery process, the recycling request medium is handed over to the user together with the sold paper curing board. This encourages the user to recycle the paper curing board at the time of purchase, thereby increasing the recycling rate. This further reduces carbon dioxide emissions.

[0020] In the above invention, it is preferable that in the delivery step, the collection request medium is handed over to the user together with the paper protective board to be lent to the user.

[0021] According to the above configuration, the collection request medium is handed over to the user together with the loaned paper curing board, which makes it easier for the user to request the collection of the paper curing board, thereby further reducing carbon dioxide emissions.

[Figure 7] 7 is a flowchart showing the procedure of a recycling method using the recycling system of FIG. 6. DETAILED DESCRIPTION OF THE INVENTION

[0030] Hereinafter, the recycled paper curing boards 1, 1A, the recycling systems 2, 2A for the paper curing boards 11, 11A, and the recycling method for the paper curing boards 11, 11A according to one embodiment of the present invention will be described with reference to the drawings. Note that the recycled paper curing boards 1, 1A, the recycling systems 2, 2A for the paper curing boards 11, 11A, and the recycling method for the paper curing boards 11, 11A are merely one embodiment of the present invention. Therefore, the present invention is not limited to the following embodiment, and additions, deletions, and modifications are possible within the scope of the invention.

[0031] The recycled paper protective board 1 shown in FIG. 1 is used to be recycled in a recycling system 2, which will be described in detail later. The recycled paper protective board 1 includes a paper protective board 11 and a collection request form 12. The paper protective board (hereinafter simply referred to as "protection board") 11 protects objects inside and outside a building during construction work or moving work. Protected objects inside and outside a building include, for example, indoor floors and walls, floors and walls of building facilities such as elevators and stairs, and floors and walls of a construction site. Buildings also include detached houses, apartment buildings, and facilities such as hospitals, office buildings, and shopping malls.

[0032] The curing board 11 is a board made from rolled paper 13 (see FIG. 2). In this embodiment, the curing board 11 is a board made from recyclable cardboard base paper, i.e., a corrugated cardboard board. More specifically, the curing board 11 is, for example, double-sided corrugated cardboard, and has two liners 11a and 11b and a core 11c (see the enlarged view in FIG. 1). The liners 11a and 11b are flat cardboard, and the core 11c is a corrugated cardboard that is formed so as to undulate in the thickness direction. The curing board 11 is configured by sandwiching the core 11c between the two liners 11a and 11b on both sides in the thickness direction and bonding them together. Note that the curing board 11 is not limited to double-sided corrugated cardboard, and may be, for example, double-sided corrugated cardboard or single-sided corrugated cardboard.

[0033] The shape of the curing board 11 is not particularly limited as long as it is a shape that corresponds to the intended use, and is, for example, rectangular. The size of the curing board 11 is also not particularly limited as long as it is a size that corresponds to the intended use. In this embodiment, the curing board 11 has a length of, for example, 1500 mm to 2000 mm and a width of, for example, 700 mm to 1000 mm. Furthermore, the curing board 11 can be folded in two as shown in FIG. 1. This makes the curing board 11 easy to carry and store.

[0034] The collection request form 12, which is an example of a collection request medium, is used to request the collection of the protective boards 11. The collection request form 12 contains, for example, information about the collection site for the protective boards 11 (e.g., the address of a construction site, the number of a collection station, and a collection store). More specifically, the collection request form 12 contains information about the collection site for the protective boards 11, as well as collection-related information including the person requesting collection, the desired collection date, and the weight (or number) of the protective boards 11 to be collected. In this embodiment, the collection request form 12 is handed over together with the protective boards 11 when they are delivered. The collection request form 12 is used as follows to collect recyclable protective boards 11 in one place. That is, after the collection-related information is written in the collection request form 12, it is transmitted to the collection company 23 using a communication device 14 connected to a communication line (e.g., a telephone line and an Internet line). In this embodiment, the collection request form 12 is sent to the collection company 23 using a fax, which is an example of the communication device 14. However, the collection request form 12 may be digitized by a computer, which is an example of the communication device 14, and then sent using an information transmission application such as email. In this way, the collection of the protective board 11 is requested by the collection request form 12.

[0035] <Recycling system for paper curing boards> In the recycling system 2 shown in Figure 2, the curing board 11 of the recycled paper curing board 1 described above is recycled. More specifically, the recycling system 2 includes a manufacturing factory 21, a distributor 22, a collector 23, a collection site 24, and a recycling factory 25. In the manufacturing factory 21, the curing board 11 is manufactured from rolled paper 13 manufactured at a paper mill 27 of the recycling factory 25, which will be described in detail later. More specifically, in the manufacturing factory 21, liners 11a, 11b and a core 11c are made from the rolled paper 13, and the core 11c is further sandwiched and bonded between the two liners 11a, 11b to produce the curing board 11.

[0036] A distributor 22, an example of a supplier, delivers the protective board 11 manufactured at the manufacturing factory 21 to a purchaser (i.e., a user). More specifically, the distributor 22 delivers the protective board 11 to the user and also hands over a collection request form 12 to the user. That is, the distributor 22 delivers the recycled paper protective board 1 to the user. Here, the purchaser / user is, for example, a construction company or a house manufacturer, and is a company that mainly works at construction sites. However, the user is not limited to construction companies or house manufacturers, and may be other people who work at construction sites. The distributor 22 is also a retailer such as a wholesaler or a home improvement store, and sells and delivers the recycled paper protective board 1 based on a request from a user. That is, the distributor 22 sells and delivers the recycled paper protective board 1. Note that delivery does not necessarily mean delivery by courier or the like, but also includes handing it over at a storefront.

[0037] The collection company 23 sets a collection route based on a collection request from the user for the protective board 11, and collects the protective board 11 from the user according to the set collection route. More specifically, the collection company 23 sets a collection route based on collection-related information in the collection request form 12 sent to it, and collects the protective board 11 from the user according to the set collection route. In this embodiment, the collection company 23 sets a collection date and collection route based on the desired collection date and collection location written in the collection request form 12, and collects the protective board 11 at the collection location using a collection vehicle 23a such as a truck.

[0038] When multiple collection requests 12 are sent, the collection company 23 sets a collection route, for example, as follows. That is, the collection company 23 inputs the desired collection date and collection location described in the collection request 12 into a computer (not shown), which is an automatic route calculation device. The computer sets a collection route for each collection date based on the input desired collection date and collection location. For example, the computer sets a collection route taking into account traffic congestion depending on the collection date and time of day, and the distance to other collection locations. As a result, five collection locations R1 to R5 shown in FIG. 3 are selected from multiple collection locations for the specified collection date, and a collection route (see the thick lines in FIG. 3) that efficiently travels around the five collection locations R1 to R5 is set. Note that the collection route does not necessarily have to be set by a computer as in this embodiment, but may be set by an employee of the collection company 23, etc. The collection company 23 then drives a collection vehicle 23a along the collection route to collect the used protective boards 11.

[0039] The collection site 24 is a place where the curing boards 11 are accumulated. The collector 23 unloads and collects the curing boards 11 collected from various locations, including collection sites R1 to R5, at the collection site 24. The curing boards 11 collected at the collection site 24 are then piled up, and the piled up curing boards 11 are compressed and packed, for example, by a packing machine. This makes it easy to transport the large amount of collected curing boards 11.

[0040] The recycling factory 25 regenerates the curing boards 11 compressed and packaged at the collection site 24 into pulp fibers and produces paper. More specifically, the curing boards 11 compressed and packaged at the collection site 24 are transported to the recycling factory 25. The transported curing boards 11 are then regenerated into pulp raw material at the recycling factory 25, and rolled paper 13 is produced from the pulp raw material. In this way, the recycling factory 25 produces rolled paper 13 from the compressed and packaged curing boards 11. More specifically, the recycling factory 25 includes a pulp recycling factory 26 and a paper mill 27.

[0041] At the pulp recycling factory 26, the collected and collected curing boards 11 are disintegrated and recycled into pulp raw material. More specifically, at the pulp recycling factory 26, the compressed and packed curing boards 11 are disintegrated by a pulper, and further, foreign matter contained in the curing boards 11 is removed. This produces pulp raw material. At the paper mill 27, paper is made using the pulp raw material produced at the pulp recycling factory 26 with a paper machine (not shown). Also at the paper mill 27, the made paper is wound onto a roll. This produces rolled paper 13. At the manufacturing factory 21, curing boards 11 are produced from the rolled paper 13 produced in this manner.

[0042] <How to recycle paper curing board> The method for recycling curing board 11, the steps of which are shown in FIG. 4 (hereinafter simply referred to as the "recycling method"), is a method for recycling curing board 11. More specifically, the recycling method includes a manufacturing process S1, a sales and delivery process S2, a use process S3, a collection request process S4, a collection and collection process S5, a pulp recycling process S6, and a papermaking process S7. In the manufacturing process S1, curing board 11 is manufactured from rolled paper 13. More specifically, in the manufacturing process S1, curing board 11 is manufactured at manufacturing factory 21 from rolled paper 13 brought in from paper factory 27. In this embodiment, as described above, two liners 11a, 11b and a core 11c are produced at manufacturing factory 21, and core 11c is sandwiched and bonded between two liners 11a, 11b to manufacture curing board 11. The manufactured protective board 11 is distributed to a distributor 22 (for example, a retail store) at the request of the distributor 22. Once the protective board 11 is manufactured, the process proceeds to a delivery process S2.

[0043] In the sales and delivery process S2, which is an example of a delivery process, the seller 22 sells the protective board 11 at the user's request and delivers it to the user. Also, in the sales and delivery process S2, a collection request form 12 is handed over to the user together with the delivery of the protective board 11. Here, handing over to the user together with the delivery of the protective board 11 includes not only handing over to the user together with the delivery of the protective board 11, but also handing over to the user in advance before delivery when the sale has been decided in advance. Once the protective board 11 is delivered, the process proceeds to the use process S3.

[0044] In the use process S3, the user uses the delivered curing board 11. The curing board 11 is used over the construction period (for example, several days to several months). After that, when the curing board 11 is damaged or no longer required to protect the floor, wall, etc., it is peeled off from the floor, wall, etc. and collected in a desired location. When unnecessary curing boards 11 are generated, the process proceeds to the collection request process S4.

[0045] In the collection request process S4, the user requests the collection company 23 to collect the protective board 11 delivered in the sales and delivery process S2 and used in the use process S3. More specifically, the user requests collection by sending a collection request form 12 containing information about collection locations R1 to R5 to the collection company 23 using a communication device 14 (a fax machine in this embodiment). Since the collection request can be made using the collection request form 12 provided along with the protective board 11, the protective board 11 is prevented from being incinerated along with industrial waste. This reduces carbon dioxide emissions. Furthermore, since the user purchases the protective board 11, they do not need to select a collection company 23 after use, which increases the convenience of the protective board 11 as a recyclable item. Once the user requests the collection company 23 to collect the protective board 11, the process proceeds to the collection and consolidation process S5.

[0046] In the collection and collection step S5, the collection company 23 collects the protective boards 11 from the user based on the collection request made in the collection request step S4. More specifically, the collection company 23 receives a collection request 12 sent from the user. The collection company 23 receives multiple collection requests 12 and acquires information about collection locations R1 to R5, such as the address of a construction site, etc., described in each collection request 12. The collection company 23 then sets a collection route for the collection vehicle 23a based on the acquired address of the construction site, etc. The collection company 23 then drives the collection vehicle 23a along the collection route to collect the protective boards 11 and collect the collected protective boards 11 at the collection point 24. The same applies when multiple collection locations are described in one collection request 12.

[0047] More specifically, the collection company 23 acquires the address of the construction site or the like written on each collection request 12, as well as the desired collection date and the amount of protection boards 11 to be collected (e.g., the number or weight of the protection boards 11 to be collected). The collection company 23 then sets a collection route for each collection date. The collection route is set, for example, by inputting the address of the construction site or the like, the desired collection date, and the amount of collection into a computer, and calculated by software. More specifically, in setting the collection route, collection sites R1 to R5 are first selected from multiple candidate collection sites based on the address of the construction site or the like, the desired collection date, the amount of collection, and the maximum load capacity of the collection vehicle 23a. Furthermore, based on the addresses of the selected collection sites R1 to R5, the collection route is set, for example, as shown in FIG. 3, starting from the collection site 24 and traveling through the first collection site R1, the second collection site R2, the third collection site R3, the fourth collection site R4, and the fifth collection site R5 in that order, and then returning to the collection site 24. The collection route does not necessarily have to be set by a computer, but may be determined and set by an employee of the collection company 23, etc. Once the collection route has been set, the collection company 23 drives the collection vehicle 23a along the collection route on the designated collection day and collects the protective boards 11 at each of the collection sites R1 to R5. After the collection company 23 collects the protective boards 11, it finally drives the collection vehicle 23a to the collection site 24 and unloads the collected protective boards 11 at the collection site 24. In this way, the collected protective boards 11 are collected at the collection site 24. Once the protective boards 11 have been collected at the collection site 24, the process proceeds to the pulp regeneration process S6.

[0048] In the pulp regeneration process S6, the collected curing boards 11 are dissolved into a fibrous form (i.e., defibrated) at the pulp regeneration factory 26 and regenerated into pulp raw material. More specifically, the collected curing boards 11 are compressed and packaged at the collection site 24. In the pulp regeneration process S6, the compressed and packaged curing boards 11 are transported to the pulp regeneration factory 26, where they are defibrated and foreign matter is removed therefrom. As a result, pulp raw material is produced at the pulp regeneration factory 26. Once the pulp raw material is produced, the process proceeds to the papermaking process S7.

[0049] In the papermaking process S7, the paper roll 13 used in the manufacturing process S1 is manufactured in the paper mill 27 from the pulp raw material recycled in the pulp recycling process S6. More specifically, in the papermaking process S7, paper is made by a paper machine (not shown) using the pulp raw material produced in the pulp recycling mill 26. In addition, in the paper mill 27, the made paper is wound around a roll to manufacture the paper roll 13. Once the paper roll 13 has been manufactured in this way, the process proceeds to the manufacturing process S1, where the curing board 11 is manufactured again from the paper roll 13 recycled from used curing board 11.

[0050] In the method for recycling the protective board 11 of this embodiment, a collection request form 12 is handed to the user in the sales and delivery process S2, and in the collection request process S4, the user uses the collection request form 12 to transmit information regarding collection locations R1 to R5 via the communication device 14 to request collection. Then, in the collection and consolidation process S5, a collection route is set in accordance with the collection request in the collection request process S4, and the protective board 11 is collected according to the set collection route. That is, collection is requested based on the request in the collection request form 12, and the protective board 11 is collected. Therefore, the user can be encouraged to collect and recycle the protective board 11 at the time of delivery, and the protective board 11 can be prevented from being incinerated together with industrial waste. This reduces carbon dioxide emissions.

[0051] Furthermore, in the method for recycling the curing board 11 of this embodiment, the curing board 11 is a corrugated cardboard board having liners 11a and 11b and a corrugated core 11c. Therefore, the curing board 11 is easy to recycle, and more curing boards 11 can be recycled. This further reduces carbon dioxide emissions.

[0052] Furthermore, in the method for recycling the curing board 11 of this embodiment, the user requests collection by filling out the collection request form 12 with information about collection locations R1 to R5 and transmitting it to the collection company 23 using the communication device 14. This makes it easy to request collection. This further encourages the recycling of the curing board 11, thereby further reducing carbon dioxide emissions.

[0053] Furthermore, in the method for recycling the protective board 11 of this embodiment, when there are multiple collection sites, the computer automatically sets a collection route based on the multiple collection sites R1 to R5. Therefore, the collection route can be set easily and efficiently.

[0054] Furthermore, in the method for recycling the curing board 11 of this embodiment, in the sales and delivery process S2, a collection request form 12 is handed over to the user together with the curing board 11 sold. This encourages the user to recycle the curing board 11 at the time of purchase, thereby increasing the collection rate. This further reduces carbon dioxide emissions.

[0055] In the case of the recycled paper protective board 1 of this embodiment, a collection request form 12 can be given to purchasers to request the collection of the cardboard protective board 11. This encourages users to collect and recycle the protective board 11, and prevents the protective board 11 from being incinerated together with industrial waste. This reduces carbon dioxide emissions.

[0056] In the recycling system 2 for the protective board 11 of this embodiment, the seller 22 hands over a collection request 12 to a user, and when the user uses the collection request 12 to request collection via the communication device 14, a collection route is set according to information about collection locations R1 to R5 described in the collection request 12, and the protective board 11 is collected according to the set collection route. That is, collection is requested based on the request in the collection request 12, and the protective board 11 is collected. This makes it possible to encourage users to collect and recycle the protective board 11, and to prevent the protective board 11 from being incinerated together with industrial waste. This reduces carbon dioxide emissions.

[0057] Second Embodiment The recycled paper curing board 1A, the recycling system 2A for the curing board 11A, and the recycling method for the curing board 11A of the second embodiment are similar in configuration to the recycled paper curing board 1, the recycling system 2A for the paper curing board 11, and the recycling method for the curing board 11 of the first embodiment. Therefore, with regard to the configuration of the recycled paper curing board 1A and the recycling system 2A for the curing board 11A of the second embodiment, and the procedure for the recycling method for the curing board 11A, we will mainly explain the differences from the recycled paper curing board 1, the recycling system 2 for the curing board 11, and the recycling method for the curing board 11 of the first embodiment, and omit explanations of the same configurations and procedures.

[0058] The recycled paper protective board 1A shown in FIG. 5 is a paper protective board that is recycled and loaned out by a recycling system 2A, which will be described in detail later. The recycled paper protective board 1A includes a protective board 11A and a collection request instruction sheet 12A. The protective board 11A, which is an example of a paper protective board, is a board material made from paper core base paper. The collection request instruction sheet 12A is a form on which the address of a collection request website (hereinafter simply referred to as the "collection request site"), which serves as a collection request medium, is written. The collection request site is a site owned by the collection company 23, and is a site where a user can access the address of the collection request site from a communication device (e.g., a computer, a smartphone, etc.) 14A and input and transmit information regarding collection locations R1 to R5 for the protective board 11.
