[First embodiment]
<Recycling method explanation>
(1) Description of the Recycling Method of the Present Disclosure First, a description will be given of a recycling method of a recycling system to which a server device according to the first embodiment is applied. Fig. 1 is a diagram showing an example of the recycling method of the present disclosure.

As shown in FIG. 1, the recycling system 100 to which the server device according to the first embodiment is applied includes an interlayer film for laminated glass manufacturing process 110, a transportation facility 120, a laminated glass manufacturing process 130, and a transportation facility 140.

The laminated glass interlayer film manufacturing process 110 has different manufacturing processes for each type of laminated glass interlayer film. The example in Figure 1 shows that the laminated glass interlayer film manufacturing process 110 has a type A manufacturing process 111, a type B manufacturing process 112, and a type C manufacturing process 113, which are manufacturing processes for producing three types of laminated glass interlayer films (type A, type B, and type C).

The Type A manufacturing process 111 is supplied with blended materials that have been blended in a blending process 114, in which Type A recycled materials and Type A virgin materials, etc. are blended. As a result, an interlayer film for laminated glass (Type A) is produced in the Type A manufacturing process 111.

The Type B manufacturing process 112 is supplied with blended materials that have been blended in a blending process 115, in which Type B recycled materials and Type B virgin materials, etc. are blended. As a result, Type B manufacturing process 112 produces an interlayer film for laminated glass (Type B).

The type C manufacturing process 113 is supplied with blended materials that have been blended in a blending process 116, in which type C recycled materials and type C virgin materials, etc. are blended. As a result, an interlayer film for laminated glass (type C) is produced in the type C manufacturing process 113.

In the example of FIG. 1, the type A manufacturing process 111, the type B manufacturing process 112, and the type C manufacturing process 113 are implemented in different manufacturing facilities. However, the type A manufacturing process 111, the type B manufacturing process 112, and the type C manufacturing process 113 may be implemented in the same manufacturing facility. Alternatively, any two of the manufacturing processes may be implemented in the same manufacturing facility.

The transport vehicle 120 transports the interlayer film for laminated glass manufactured in the interlayer film for laminated glass manufacturing process 110 to a delivery destination. In the example of FIG. 1 , the transport vehicle 120
- An interlayer film for laminated glass (Type A) manufactured in Type A manufacturing process 111;
- An interlayer film for laminated glass (type B) manufactured in type B manufacturing process 112;
- An interlayer film for laminated glass (type C) manufactured in type C manufacturing process 113;
The figure shows the process of transporting the goods to their destination.

The laminated glass manufacturing process 130 has different manufacturing processes for each application of the laminated glass. The example in Figure 1 shows that the laminated glass manufacturing process 130 has a manufacturing process for mobility I, a manufacturing process for mobility II, a manufacturing process for residential infrastructure I, and a manufacturing process for residential infrastructure II to manufacture laminated glass for each of the four applications.

In the manufacturing process 131 for Mobility I, laminated glass for Mobility I is manufactured using an interlayer film for laminated glass (Type A). At this time, the interlayer film for laminated glass (Type A) is cut out to fit the size and shape of the laminated glass, and any unnecessary portions are discarded as cut-out parts in a Type A box 135.

In the manufacturing process 132 for Mobility II, laminated glass for Mobility II is manufactured using an interlayer film for laminated glass (type B). At this time, the interlayer film for laminated glass (type A) is cut out to fit the size and shape of the laminated glass, and the unnecessary portion is discarded as a cut-out material in a box 136 for type B.

In the manufacturing process 133 for residential infrastructure I, laminated glass for residential infrastructure I is manufactured using interlayer film for laminated glass (type C). At this time, the interlayer film for laminated glass (type C) is cut to fit the size and shape of the laminated glass, and the unnecessary portion is discarded as a cut-out material in type C box 137.

In the manufacturing process 134 for residential infrastructure II, laminated glass for residential infrastructure II is manufactured using interlayer film for laminated glass (type C). At this time, the interlayer film for laminated glass (type C) is cut to fit the size and shape of the laminated glass, and the unnecessary portion is discarded as a cut-out material in a type C box 138.

In the example of Figure 1, Mobility I manufacturing process 131, Mobility II manufacturing process 132, Residential Infrastructure I manufacturing process 133, and Residential Infrastructure II manufacturing process 134 are assumed to be realized in the same factory. However, Mobility I manufacturing process 131, Mobility II manufacturing process 132, Residential Infrastructure I manufacturing process 133, and Residential Infrastructure II manufacturing process 134 may be realized in different factories. Alternatively, any one manufacturing process may be realized in a different factory from the other three manufacturing processes. Alternatively, any two manufacturing processes may be realized in a different factory from the other two manufacturing processes. Alternatively, any two manufacturing processes may be realized in a different factory from the other two manufacturing processes, and the other two manufacturing processes may also be realized in different factories.

The transporting means 140 transports the cut-out members discarded in the laminated glass manufacturing process 130 as recycled materials by film type. In the example of FIG. 1 , the transporting means 140
- Type A cutout members discarded in the manufacturing process 131 for mobility I;
- Type B cutout members discarded in the manufacturing process 132 for mobility II;
-Cutout members of type C discarded in the building infrastructure I manufacturing process 133 and the building infrastructure II manufacturing process 134;
The figure shows how the membranes are transported as recycled materials, separated by type.

In this way, the recycling system 100 collects recycled materials for each film type from the recipients of interlayer films for laminated glass, and then blends the recycled materials collected for each film type with virgin materials for each film type to newly manufacture interlayer films for laminated glass of the corresponding film type.

(2) Description of a Comparative Recycling Method Next, a comparative recycling method will be described in order to clarify the characteristics of the recycling method (FIG. 1) of the present disclosure.

(2-1) Explanation of the recycling method of the first comparative example Fig. 2A is a diagram showing the recycling method of the first comparative example. Note that the same components as those in the recycling system 100 shown in Fig. 1 are denoted by the same reference numerals, and their explanations will be omitted.

As shown in Figure 2A, the recycling system 200-1 includes a laminated glass interlayer film manufacturing process 210-1, a transportation system 120, a laminated glass manufacturing process 230-1, and a transportation system 140.

The Type A manufacturing process 111 is supplied with blended materials that have been blended in a blending process 214, in which recycled materials whose adhesive strength-adjusting effect has been inactivated by adjusting their moisture content in a moisture content adjustment process 217 are blended with Type A virgin materials, etc. In this way, an interlayer film for laminated glass (Type A) is produced in the Type A manufacturing process 111.

The Type B manufacturing process 112 is supplied with blended materials that have been blended in a blending process 215, in which recycled materials whose adhesive strength-adjusting effect has been inactivated by adjusting their moisture content in a moisture content adjustment process 217 are blended with Type B virgin materials, etc. As a result, an interlayer film for laminated glass (Type B) is produced in the Type B manufacturing process 112.

The Type C manufacturing process 113 is supplied with blended materials that have been blended in a blending process 216, in which recycled materials whose adhesive strength-adjusting effect has been inactivated by adjusting their moisture content in a moisture content adjustment process 217 are blended with Type C virgin materials, etc. In this way, an interlayer film for laminated glass (Type C) is produced in the Type C manufacturing process 113.

Laminated glass manufacturing process 230-1 has different manufacturing processes for each application of the laminated glass. In the example of Figure 2A, as in the example of Figure 1, laminated glass manufacturing process 230-1 has manufacturing processes for manufacturing laminated glass for each of the four applications. However, in the case of Figure 2A, the type A cut-out members, type B cut-out members, and type C cut-out members cut out in each manufacturing process are all discarded in box 235.

Transportation vehicle 140 transports the cut-out members of each film type discarded in laminated glass manufacturing process 230-1 as recycled materials. In this way, in the case of the first comparative example, recycled materials containing a mixture of cut-out members of different film types are collected, so in the moisture content adjustment process 217, the moisture content is adjusted to eliminate differences in the characteristics (adhesive strength) of each film type and allow the material to be used for any film type. As a result, according to the first comparative example, even if cut-out members of different film types are mixed, they can be used as recycled materials.

In the example of Figure 2A, differences in adhesive strength are used as an example of differences in characteristics between film types, but the same applies to differences in characteristics other than adhesive strength. In such cases, however, instead of the moisture content adjustment process 217, an adjustment process is performed to eliminate differences in characteristics other than adhesive strength.

(2-2) Explanation of the Recycling Method of the Second Comparative Example Figure 2B is a diagram showing the recycling method of the second comparative example. Note that the same components as those in the recycling system 100 or the recycling system 200-1 shown in Figure 1 or Figure 2A are denoted by the same reference numerals, and their explanations will be omitted here.

As shown in Figure 2B, the recycling system 200-2 includes a laminated glass interlayer film manufacturing process 210-2, a transportation facility 120, a laminated glass manufacturing process 230-2, a mobile object manufacturing process 250, a construction process 260, and a transportation facility 140.

Laminated glass manufacturing process 230-2 has different manufacturing processes for each application of the laminated glass. In the example of Figure 2B, similar to the examples of Figures 1 and 2A, laminated glass manufacturing process 230-1 has manufacturing processes for manufacturing laminated glass for each of the four applications. However, in the case of Figure 2B, the cut-out parts cut out in each manufacturing process are not recovered.

The mobile body manufacturing process 250 manufactures a mobile body 251 using the laminated glass manufactured in the mobility I manufacturing process 131 and the mobility II manufacturing process 132. For example, the mobile body manufacturing process 250
- Laminated glass manufactured in the manufacturing process 131 for mobility I (for example, a windshield compatible with a HUD (Head Up Display)),
- Laminated glass (for example, roof glass with high heat insulation properties) manufactured in the manufacturing process 132 for mobility II;
To manufacture automobiles using

In the construction process 260, a building 261 is constructed using the laminated glass manufactured in the building infrastructure I manufacturing process 133 and the building infrastructure II manufacturing process 134. For example, in the construction process 260,
- Laminated glass manufactured in the manufacturing process for residential infrastructure (for example, show window glass with high UV cutoff),
- Laminated glass manufactured in the manufacturing process for residential infrastructure II (for example, curtain walls with high sound insulation),
Use it to construct a building.

When mobile object 251 is discarded or building 261 is demolished, the laminated glass used in manufacturing mobile object 251 or the laminated glass used in constructing building 261 is disposed of as waste in box 270. The discarded laminated glass contains a mixture of interlayer films of various types that can be used as recycled materials.

Transportation vehicle 140 transports discarded waste (laminated glass). In this way, in the second comparative example, waste (laminated glass) containing interlayer films of different film types is collected as recyclable material. For this reason, in the methanol dissolution and glass peeling and removal process 219, the interlayer films contained in the waste (laminated glass) are liquefied by dissolving them in methanol, and the glass is removed by filtering. Next, in the solvent removal process 218, the solvent is removed from the interlayer film liquefied by dissolving it in methanol. Next, in the water content adjustment process 217, the water content is adjusted to eliminate differences in the characteristics of each film type and enable use with any film type. As a result, according to the second comparative example, even if interlayer films of different film types are mixed, they can be used as recyclable material.

(3) Characteristics of the recycling method of the present disclosure As is clear from a comparison of (1) above with (2-1) and (2-2) above, the recycling method of the recycling system 100 to which the server device of the first embodiment is applied has the following characteristics.
The recycled materials themselves (which do not contain glass, etc.) are separated and collected by film type. Therefore, in the case of the interlayer film for laminated glass manufacturing process 110, various processes for making the collected recycled materials usable (such as the water content adjustment process 217, the solvent removal process 218, and the methanol dissolution and glass peeling and removal process 219) are not necessary. As a result, the manufacturing costs of the interlayer film for laminated glass can be reduced.
- The recycled materials themselves (which do not contain glass, etc.) are collected separately by film type. This makes it possible to collect recycled materials with a high level of quality, and the recycled material content can be increased when manufacturing interlayer films for laminated glass. As a result, the environmental impact can be reduced.
- Cutouts are collected by film type as recycled materials. This ensures a stable collection volume of recycled materials. As a result, it becomes easier to plan production when manufacturing interlayer films for laminated glass using recycled materials.

<System configuration of information processing system>
Next, a system configuration of an information processing system having a server device according to the first embodiment will be described. Fig. 3 is a diagram showing an example of the system configuration of an information processing system having a server device according to the first embodiment. As shown in Fig. 3, an information processing system 300 includes an interlayer film for laminated glass manufacturing process 110 and a server device 310.

As explained using Figure 1, the laminated glass interlayer film manufacturing process 110 includes a type A manufacturing process 111, a type B manufacturing process 112, and a type C manufacturing process 113, each of which uses the corresponding blended materials to manufacture the corresponding type of laminated glass interlayer film.

In the example of Figure 3, the type A manufacturing process 111, type B manufacturing process 112, and type C manufacturing process 113 are implemented in different manufacturing facilities. However, the type A manufacturing process 111, type B manufacturing process 112, and type C manufacturing process 113 may be implemented in the same manufacturing facility. Alternatively, any two of the manufacturing processes may be implemented in the same manufacturing facility.

When recycled materials used in compounding materials are collected, the laminated glass interlayer film manufacturing process 110 acquires recycled material information at the time of collection ("collection information"), including the collected amount, collection date, collection source, film type, etc., and transmits this information to the server device 310. Instead of the laminated glass interlayer film manufacturing process 110 transmitting the collection information to the server device 310, for example, the administrator of the information processing system 300 may manually enter the collection information into the server device 310. Alternatively, the administrator (seller) of the laminated glass manufacturing process 130 may transmit the collection information to the server device 310 when the recycled materials are bought and sold.

Furthermore, the laminated glass interlayer film manufacturing process 110 inspects the quality level of recycled materials used in the compounding materials after collection. The laminated glass interlayer film manufacturing process 110 transmits the results of the quality inspection to the server device 310 as recycled material inspection information ("inspection information"). At that time, the laminated glass interlayer film manufacturing process 110 transmits information about the source of the recycled materials and the manufacturer of the recycled materials together to the server device 310.

Once the manufactured interlayer film for laminated glass is shipped, a transport vehicle 120 transports the interlayer film for laminated glass to the delivery destination. At the time of shipment, the interlayer film for laminated glass manufacturing process 110 transmits interlayer film information at the time of shipment ("shipping information") to the server device 310, including the shipping quantity, shipping destination, shipping date, delivery date, film type, material information, etc.

An information processing program is installed on the server device 310, and when this program is executed, the server device 310 functions as an information processing unit 320.

The information processing unit 320 acquires input information and stores it in the input information storage unit 330. The input information acquired by the information processing unit 320 includes information transmitted from the laminated glass interlayer film manufacturing process 110, such as the above-mentioned shipping information, inspection information, and recovery information, as well as "price information" entered by the administrator of the information processing system 300.

Price information refers to buying and selling price information, including the purchase price of recycled materials and the selling price of interlayer films for laminated glass manufactured using recycled materials.

In addition, the information processing unit 320 reads the input information stored in the input information storage unit 330 and performs various processes, outputting (displaying) the processing results as output information and storing them in the output information storage unit 340. The output information output by the information processing unit 320 includes not only the collection information, price information, and inspection information entered as input information, but also "stock information," "environmental information," "reduction information," "deadline information," etc. calculated by the information processing unit 320 performing various processes.

Stock information refers to the stock amount (estimated value) of cut-out materials at the collection source, calculated based on the shipping amount.

Environmental information refers to information related to the environmental impact, including information on the environmental impact of manufacturing interlayer film for laminated glass, and information on the reduction of environmental impact resulting from the incorporation of recycled materials in the manufacturing of interlayer film for laminated glass.

Reduction information refers to information on material cost reduction, including the effect of reducing material procurement costs by incorporating recycled materials.

Expiry date information refers to information about recycled materials, including the number of days since the recycled material was last used and the expiration date indicating the date by which the recycled material can be used to manufacture interlayer film for laminated glass.

In this way, by applying the server device 310 to the recycling system 100 and making the server device 310 function as the information processing unit 320, the server device 310 can perform the following for each film type:
・Information about interlayer film for laminated glass (interlayer film information at the time of shipment),
- Information on recycled materials (recycled material inspection information, recycled material information at the time of collection, collection source stock information, recycled material expiration date information),
- Information on the prices of recycled materials and interlayer films for laminated glass (buying and selling price information);
- Information on the effects of using recycled materials (information on environmental impact, information on material cost reduction),
can be input as input information or output as output information.

Note that while the example in Figure 3 shows a case where the server device 310 is operated and managed in-house, the server device 310 may also be located on the cloud. In other words, the information processing unit 320, input information storage unit 330, and output information storage unit 340 may be implemented in a server device 310 (an on-premises server) operated and managed in-house, or in a server device 310 (an external server) on the cloud.

<Specific examples of input and output information>
Next, specific examples of input information input by or output information output from information processing unit 320 of server device 310 will be described.

(1) Specific Examples of Input Information Fig. 4A is a diagram showing specific examples of input information input to the server device according to Embodiment 1. As shown in Fig. 4A, the input information includes input information 410 input for each interlayer film for laminated glass to be shipped and input information 420 input for each recycled material collected.

Of these, input information 410 includes "interlayer film information at time of shipping" and "purchase price information." As mentioned above, "interlayer film information at time of shipping" is referred to as "shipping information" and includes shipping quantity, shipping destination, shipping date, delivery date, film type, material information, etc.

In the example of Figure 4A, it shows that an interlayer film for laminated glass with film type = "Type A" was shipped on shipping date = "xx/yy/zz" to shipping destination = "Company Y" in quantity = "X [t]", and delivered to the shipping destination on delivery date = "xx/yy/zz'".

The example in Figure 4A shows that the interlayer film for laminated glass was manufactured using a blend of recycled material content = "r [%]" and virgin material content = "v [%]".

When the recycled material content ratio is entered, the recycled material content in the shipping volume of the interlayer film for laminated glass (i.e., the amount of recycled material mixed in when the interlayer film for laminated glass was manufactured) is calculated. Furthermore, when the amount of recycled material mixed in when the interlayer film for laminated glass was manufactured is calculated, the amount of GHG emissions (an example of environmental impact information) from the recycled material when the interlayer film for laminated glass was manufactured is calculated. The example in Figure 4A shows that the amount of GHG emissions from the recycled material when X [t] of interlayer film for laminated glass was manufactured was rg [t].

Similarly, when the content ratio of virgin materials is input, the content of virgin materials in the shipped amount of interlayer film for laminated glass (i.e., the amount of virgin materials blended when the interlayer film for laminated glass was manufactured) is calculated. Furthermore, when the amount of virgin materials blended when the interlayer film for laminated glass was manufactured is calculated, the amount of GHG emissions (an example of environmental impact information) from the virgin materials when the interlayer film for laminated glass was manufactured is calculated. In the example of Figure 4, this shows that the amount of GHG emissions from virgin materials when X [t] of interlayer film for laminated glass was manufactured was vg [t].

As mentioned above, "purchase price information" is referred to as "price information" and includes the purchase price of recycled materials used in the production of interlayer films for laminated glass, the selling price of such interlayer films for laminated glass, etc.

In the example of Figure 4A, the purchase price of Type A recycled material is F [yen], and the sales price of Type A interlayer film for laminated glass manufactured using that recycled material is G [yen].

On the other hand, input information 420 includes "recycled material inspection information" and "recycled material information at the time of collection."

As mentioned above, "recycled material inspection information" is also referred to as "inspection information" and includes the results of quality inspections of recycled materials, information indicating the source from which the recycled materials were collected, information indicating the manufacturer of the recycled materials, etc.

In the example shown in Figure 4A, the recycled material collected was a cut-out piece of interlayer film for laminated glass that the company had previously shipped to "Company Y." After collection, a quality inspection was conducted and the quality level was found to be good.

As mentioned above, "recycled material information at the time of collection" is referred to as "collection information" and includes the amount collected, collection date, collection source, film type, etc.

In the example of Figure 4A, it shows that on collection date = "xx year yy' month zz" day, cut-out members with film type = "Type A" were collected as recyclable materials in an amount = "D [t]" from collection source = "Company Y".

(2) Specific Examples of Output Information Fig. 4B is a diagram showing a specific example of output information output from the server device according to Embodiment 1. As shown in Fig. 4B, the output information includes output information 430 output for each collected recycled material and output information 440 output for each interlayer film for laminated glass to be shipped.

Output information 430 includes "recycled material information at time of collection" and "collection source stock information." As mentioned above, "recycled material information at time of collection" is referred to as "collection information," and includes the amount collected, collection date, collection source, film type, etc. Note that the "recycled material information at time of collection" in output information 430 is the same as the "recycled material information at time of collection" in input information 420, so explanation will be omitted here.

In addition, "recovery source stock information" is referred to as "stock information" as described above, and includes information such as the stock amount of cut-out materials at the recovery source.

The stock amount of cut-out elements at the collection source = "E [t]" is the stock amount (estimated value) held by collection source = "Company Y" before collection, and is calculated based on the shipment amount of "Type A" interlayer film for laminated glass shipped to "Company Y" before collection. Specifically, it is calculated by calculating the weight per cut-out element from the size of each cut-out element, and multiplying this by the number of cut-out elements derived from the shipment amount.

The stock amount of cut-out materials at the collection source = "E[t]" may be updated after collection. For example, the stock amount (estimated value) of cut-out materials from collection source = "Company Y" is calculated by subtracting the collected amount = "D[t]" from the stock amount (estimated value) of cut-out materials from collection source = "Company Y" before collection.

On the other hand, output information 440 includes "information regarding environmental impact," "material cost reduction information," "purchase price information," "recycled material deadline information," and "recycled material inspection information."

As described above, "information regarding environmental load" is called "environmental information" and includes GHG emissions (an example of environmental load information), GHG emission reduction amounts (an example of information regarding environmental load reduction), etc. Note that environmental information is not limited to GHG emissions and GHG emission reduction amounts, and includes any information related to environmental load, such as _CO2 emissions.

GHG emissions are calculated by adding the GHG emissions from recycled materials ("rg [t]") in input information 410 and the GHG emissions from virgin materials ("vg [t]") in input information 410. The example in Figure 4B shows that the GHG emissions are K [t] when X [t] of Type A interlayer film for laminated glass is produced with a recycled material content of "r [%]" and a virgin material content of "v [%]".

The GHG emission reduction amount is calculated as the difference between the amount of GHG emissions when an interlayer film for laminated glass is produced without blending recycled materials and the amount of GHG emissions when an interlayer film for laminated glass is produced with blending recycled materials.
The amount of GHG emissions (not shown) when X [t] of interlayer film for laminated glass of type A is produced with a virgin material content of 100 [%],
The amount of GHG emissions when X [t] of type A interlayer film for laminated glass is produced with a recycled material content of r [%] and a virgin material content of v [%] is K [t].
This indicates that the difference between the two is L[t].

"Material cost reduction information," also known as "reduction information," includes the effect of reducing material procurement costs by using recycled materials. It is calculated as the difference between the material procurement cost when manufacturing an interlayer film for laminated glass without incorporating recycled materials and the material procurement cost when manufacturing an interlayer film for laminated glass with the incorporation of recycled materials. The example in Figure 4B shows that the difference between the material procurement cost when manufacturing an interlayer film for laminated glass without incorporating recycled materials and the material procurement cost when manufacturing an interlayer film for laminated glass with the incorporation of recycled materials was M [yen].

As mentioned above, "purchase and sale price information" is also referred to as "price information" and includes the purchase price of recycled materials used in the production of interlayer films for laminated glass, the selling price of the interlayer films for laminated glass, etc. Note that the "purchase and sale price information" in output information 440 is the same as the "purchase and sale price information" in input information 420, so further explanation will be omitted here.

"Recycled material expiration date information" is also referred to as "expiration date information" and includes the number of days since the recycled material was last used, the expiration date for the recycled material, etc.

The number of days since the recycled material was collected is the number of days from the collection date (xx year, yy' month, zz" day) in the recycled material information at the time of collection in input information 420 to the present. The example in Figure 4B shows that P [days] have passed. Note that "present" here refers to a day after the collection date on which the recycled material was collected, but before the manufacturing date on which the interlayer film for laminated glass was manufactured using the recycled material.

In the case of Figure 4B, the expiration date of the recycled material is the expiration date of the recycled material when Type A recycled material is used to manufacture Type A interlayer film for laminated glass, and the example in Figure 4B shows that it is Q [days].

Note that the number of days elapsed for recycled materials and the expiration date for recycled materials are not limited to this. For example, the number of days elapsed for recycled materials may be the number of days elapsed from the shipping date of an interlayer film for laminated glass manufactured with a virgin material content of 100%. Similarly, the expiration date for recycled materials may be the expiration date calculated from the shipping date of an interlayer film for laminated glass manufactured with a virgin material content of 100%.

As mentioned above, "recycled material inspection information" is also referred to as "inspection information," and the quality inspection results of the recycled material are output as output information 440 from the "recycled material inspection information" input as input information 420. Note that the "recycled material inspection information" in output information 440 is the same as the "recycled material inspection information" in input information 420, so further explanation will be omitted here.

<Input/output timing of input and output information>
Next, the input timing of the input information 410, 420 shown in Fig. 4A and the output timing of the output information 430, 440 shown in Fig. 4B will be described. Fig. 5 is a diagram showing an example of the input/output timing of the input information and the output information processed in the server device according to the first embodiment. Note that in Fig. 5, due to space limitations, each item of the input information 410, 420 is indicated by an information ID (see Fig. 4A). Similarly, in Fig. 5, due to space limitations, each item of the output information 430, 440 is indicated by an information ID (see Fig. 4B).

When Type A interlayer film for laminated glass is shipped (see reference numeral 501), the interlayer film information at the time of shipment (information IDs SH1 to SH9) is entered as input information 410 (not shown in FIG. 5). Therefore, the information processing unit 320 of the server device 310 uses the shipped quantity (information ID = SH1) to calculate the stock quantity (information ID = SK1) of cut-out materials at the collection source (see reference numeral 502) and outputs this as output information 430 (see reference numeral 511). In addition to calculating the stock quantity (information ID = SK1) using the shipped quantity (information ID = SH1), the information processing unit 320 of the server device 310 may also use the delivery date (information ID = SH4) to calculate and output the collection timing (not shown).

Next, when Type A interlayer film for laminated glass is produced (see reference numeral 506),
- Recycled material content ratio (information ID = SH6),
- Virgin material content (information ID = SH8),
is input, information processing unit 320 of server device 310 stores this as input information 410 in input information storage unit 330. Furthermore, information processing unit 320 of server device 310 calculates the GHG emission amount of the recycled material (information ID = SH7) based on the recycled material content ratio (information ID = SH6), and stores this as input information 410 in input information storage unit 330. Furthermore, information processing unit 320 of server device 310 calculates the GHG emission amount of the virgin material (information ID = SH9) based on the virgin material content ratio (information ID = SH8), and stores this as input information 410 in input information storage unit 330.

Furthermore, the information processing unit 320 of the server device 310 calculates the GHG emission amount of the recycled material (information ID=SH7) and the GHG emission amount of the virgin material (information ID=SH9) stored in the input information storage unit 330,
・GHG emissions (information ID=EN1),
・GHG emission control amount (information ID=EN2),
and outputs it as output information 440 (see reference numeral 514). Note that when the type A interlayer film for laminated glass is manufactured (see reference numeral 506), the information processing unit 320 of the server device 310 calculates the value of the recycled material collection date as the starting date, as follows:
- Number of days since recycling of materials (information ID=ST1),
- expiry date of recycled materials (information ID=ST2),

The hardware components of the server device 310 are connected to each other via a bus 607.

The processor 601 has various computing devices such as a CPU (Central Processing Unit) and a GPU (Graphics Processing Unit). The processor 601 reads various programs (e.g., information processing programs) into the memory 602 and executes them.

Memory 602 includes a primary storage device such as ROM (Read Only Memory) and RAM (Random Access Memory). The processor 601 and memory 602 form what is known as a computer, and the computer realizes various functions by the processor 601 executing various programs loaded onto memory 602.

The auxiliary storage device 603 stores various programs and various data used when the various programs are executed by the processor 601. For example, the input information storage unit 330 and the output information storage unit 340 are realized in the auxiliary storage device 603.

The I/F device 604 is a connection device for connecting the operation device 611 and display device 612, which are examples of external devices, to the server device 310. For example, when an administrator of the information processing system 300 manually inputs input information 420, he or she inputs the information via the operation device 611. In addition, the output information 430 and 440 is output (displayed) on the display device 612.

Alternatively, the various programs installed in the auxiliary storage device 603 may be installed by downloading them from a network via the communication device 605.

<Types of interlayer films for laminated glass>
Next, specific examples of film types for interlayer films for laminated glass will be described. Fig. 7 is a diagram showing specific examples of film types for interlayer films for laminated glass. As shown in Fig. 7, interlayer films for laminated glass include, for example, sound insulation films, heat insulation films, UV-cut films, wedge films, regular films, and color films.

Sound-proofing membranes are interlayer films that block external sounds and noises. They are used, for example, in laminated glass for automobiles, to significantly reduce the transmission of noises that enter from outside the vehicle, such as traffic noise and wind noise.

A heat-shielding film is an interlayer film that functions to suppress indoor temperature changes caused by sunlight, and is used, for example, in laminated glass for automobiles.

UV-cutting film is an interlayer film that has the function of blocking ultraviolet rays. It is used, for example, in laminated glass for automobiles, to improve the environment inside the car and prevent damage to the skin caused by sunburn.

Wedge membrane is a type of interlayer film used in automobile windshields, and when processed into a wedge shape, it plays a role in improving HUD visibility.

Normally, membranes are used in laminated glass to absorb the impact of a collision, prevent penetration, and prevent fragments from flying when the glass breaks.

Color films are used in laminated glass to provide the glass with a variety of natural color variations.

<Functional configuration of the information processing unit of the server device>
Next, the functional configuration of the information processing unit 320 of the server device 310 will be described in detail. Fig. 8 is a diagram showing the functional configuration of the information processing unit of the server device according to the first embodiment. As shown in Fig. 8, the information processing unit 320 includes an acquisition unit 810, a calculation unit 820, and an output unit 830.

The acquisition unit 810 acquires shipping information, inspection information, recall information, and price information, and stores it in the input information storage unit 330. The acquisition unit 810 also reads shipping information, inspection information, recall information, and price information from the input information storage unit 330, notifies the calculation unit 820 of some of the information, and notifies the output unit 830 of the remaining information.

The calculation unit 820 calculates stock information, environmental information, reduction information, and deadline information based on the shipping information, collection information, and price information notified from the acquisition unit 810, and notifies the output unit 830.
Stock information (stock amount of cut-out materials at the collection source (information ID=SK1)) is calculated based on the shipping amount (information ID=SH1) of the previous shipping information.
- Calculate environmental information (GHG emissions (information ID = EN1), GHG emission reduction amount (information ID = EN2)) based on the GHG emissions of recycled materials (information ID = SH7) and GHG emissions of virgin materials (information ID = SH9) in the current shipping information.
Based on the collection date (information ID=CL3) in the collection information, deadline information (the number of days since the recycled material was last used (information ID=ST1), the expiration date for using the recycled material (information ID=ST2)) is calculated. Alternatively, based on the shipping date (information ID=SH3) of an interlayer film for laminated glass manufactured with a virgin material content of 100% (information ID=SH3), deadline information (the number of days since the recycled material was last used (information ID=ST1), the expiration date for using the recycled material (information ID=ST2)) is calculated.
- Based on the purchase price of recycled materials in the price information (information ID=PR1), reduction information (the effect of reducing material procurement costs by using recycled materials (information ID=RE1)) is calculated.

The output unit 830 outputs the inspection information, collection information, and price information notified by the acquisition unit 810, and the stock information, environmental information, reduction information, and deadline information notified by the calculation unit 820 as output information, and stores it in the output information storage unit 340.

<Details of each process executed on the server device>
Next, the details of each process executed by the server device 310 will be described. Specifically, each process is as follows:
- Processing to calculate stock amount,
- Processing to inspect recycled materials;
- Processing to calculate the age of recycled materials and the expiration date of recycled materials;
- Processing to calculate GHG emissions and GHG emission reduction amounts,
- Calculating the reduction effect of material procurement costs,
Details will be explained below.

(1) Details of the process for calculating the stock amount of cut-out materials to be collected Figure 9 is a diagram showing details of the process for calculating the stock amount of cut-out materials to be collected. As an example, it shows details of the process for calculating the stock amount of cut-out materials generated when manufacturing automobile roof glass.

The roof glass 902 of the automobile 901 is made of laminated glass, and an interlayer film for laminated glass is arranged as shown by the reference numeral 903. Specifically, gray color films 911 and 912 are arranged above and below the switchable film 913, and a regular film is arranged around the periphery of the switchable film 913. Note that the switchable film is a film whose transparency can be switched by turning the power on and off. Wiring for the power supply is attached to the periphery of the switchable film 913, and the regular film 914 is arranged in the position where the wiring is attached.

For this reason, the normal film 914 is generated by cutting out the center portion of a normal film 920 that has been processed to the same shape and size as the color films 911 and 912. The cutout member 930 cut out from the normal film 920 has the same shape and size as the switchable film 913.

Therefore, in the information processing unit 320 of the server device 310, the calculation unit 820 calculates
Calculating the number of sheets of normal film 914 to be produced based on the shipping amount of normal film used for the roof glass 902 of the automobile 901;
Calculate the weight of each cutout member 930 from the area of the switchable film 913,
Multiply the number of regular membranes 914 by the weight of each cutout member 930;
In this way, the stock amount of cut-out materials is calculated.

(2) Details of the Process for Inspecting Recycled Materials Fig. 10 is a diagram showing details of the process for inspecting recycled materials. As shown by reference numeral 1010 in Fig. 10, when multiple cut-out members 930 are collected as recycled materials in a state where they are overlapped on top of each other, the recycled materials are cut (reference numeral 1020) in the interlayer film for laminated glass manufacturing process 110.

Next, in the laminated glass interlayer film manufacturing process 110, the cut recycled material is photographed and inspected based on the photographed image to determine the quality level of the recycled material (reference numeral 1030). In the laminated glass interlayer film manufacturing process 110, if the recycled material is found to contain foreign matter as a result of inspection, the foreign matter is removed and the recycled material is inspected again.

In the information processing unit 320 of the server device 310, the acquisition unit 810 acquires the quality inspection results 1050 of the recycled material and stores them in the input information storage unit 330. The output unit 830 outputs the quality inspection results 1050 of the recycled material as inspection information. Note that the example in Figure 10 indicates that the quality inspection of the recycled material has been completed and that the quality level was good as the quality inspection results 1050 of the recycled material.

(3) Details of the Process for Calculating the Number of Elapsed Days and the Use-by Date of Recycled Materials Figure 11 shows details of the process for calculating the number of elapsed days and the use-by date of recycled materials. Of these figures, Figure 11(a) shows details of the process for calculating the number of elapsed days and the use-by date, starting from the collection date of the recycled materials. As described above, when recycled materials are used to manufacture interlayer films for laminated glass, a use-by date is set (reference numeral 1110) indicating the period during which the recycled materials can be used. Therefore, in the interlayer film for laminated glass manufacturing process 110, it is required to manufacture an interlayer film for laminated glass using the collected recycled materials by the use-by date.

When the collection date of the recyclable materials is input as input information 420, the information processing unit 320 of the server device 310 sets the expiration date (reference numeral 1110) using the collection date as the starting date, and manages the number of days elapsed since the collection date. Figure 11(a) shows the calculation of the number of days elapsed until the current date, reference numeral 1101.

Figure 11(b) shows details of the process for calculating the number of days elapsed and the expiration date, starting from the shipping date of an interlayer film for laminated glass manufactured without incorporating recycled materials, in the interlayer film for laminated glass manufacturing process 110. As described above, when recycled materials are used to manufacture an interlayer film for laminated glass, an expiration date indicating the date by which the material can be used is set (reference numeral 1120). For this reason, the information processing unit 320 of the server device 310 is required to manage the number of days elapsed from the shipping date of an interlayer film for laminated glass manufactured without incorporating recycled materials.

When the shipping date of an interlayer film for laminated glass manufactured without incorporating recycled materials is input as input information 410, the information processing unit 320 of the server device 310 sets the expiration date (reference numeral 1120) using the shipping date as the starting date, and manages the number of days elapsed since the shipping date. Figure 11(b) shows the calculation of the number of days elapsed until the current date, reference numeral 1102.

(4) Details of the process for calculating GHG emission amount and GHG emission reduction amount Fig. 12 is a diagram showing details of the process for calculating GHG emission amount and GHG emission reduction amount. Of these, Fig. 12(a) is a diagram showing details of the process for calculating GHG emission amount. The information processing unit 320 of the server device 310 produces an interlayer film for laminated glass containing recycled materials, calculates the GHG emission amount of recycled materials and the GHG emission amount of virgin materials, and calculates the GHG emission amount by adding both.

Figure 12(b) shows the details of the process for calculating the GHG emission reduction amount. The information processing unit 320 of the server device 310 calculates the GHG emission amount when an interlayer film for laminated glass is manufactured using recycled materials, and then calculates the GHG emission amount when an interlayer film for laminated glass is manufactured without using recycled materials, and calculates the difference between the two. This allows the information processing unit 320 of the server device 310 to calculate the GHG emission reduction amount achieved by using recycled materials.

(5) Details of the process for calculating the effect of reducing material procurement costs Fig. 13 is a diagram showing the details of the process for calculating the effect of reducing material procurement costs. As described above, the effect of reducing material procurement costs by using recycled materials is calculated as follows:
- The cost of materials procurement when manufacturing interlayer films for laminated glass without blending recycled materials,
- The cost of materials procurement when manufacturing interlayer films for laminated glass by blending recycled materials,
It is calculated by the difference between

In Figure 13, (a) and (b) show the flow for manufacturing an interlayer film for laminated glass without incorporating recycled materials. Of these, Figure 13(a) shows how an interlayer film for laminated glass is manufactured by procuring PVA resin 1310 as a virgin material, producing PVB resin 1311, and adding plasticizers, etc. 1312. In this case, the material procurement cost is the sum of the procurement cost of PVA resin 1310 and the procurement cost of plasticizers, etc. 1312.

Figure 13(b) also shows how PVB resin 1320 is procured as virgin material and plasticizers 1312 are added to produce an interlayer film for laminated glass. In this case, the material procurement cost is the sum of the procurement cost of PVB resin 1320 and the procurement cost of plasticizers 1322.

On the other hand, Figure 13(c) shows the process for manufacturing an interlayer film for laminated glass by blending recycled materials. As shown in Figure 13(c), recycled materials 1330 are crushed, separated, or melted, and then PVB resin and plasticizers 1332 are added to produce the interlayer film for laminated glass. In this case, the material procurement cost is the sum of the procurement cost of recycled materials 1330 and the procurement cost of PVB resin and plasticizers 1332.

Therefore, in the information processing unit 320 of the server device 310, the calculation unit 820 calculates
The sum of the procurement cost of the PVA resin 1310 and the procurement cost of the plasticizer etc. 1312,
The sum of the procurement cost of recycled materials 1330 and the procurement cost of PVB resin and plasticizers 1332,
By calculating the difference between the two, the effect of reducing material procurement costs by using recycled materials is calculated.

Alternatively, in the information processing unit 320 of the server device 310, the calculation unit 820
The sum of the procurement cost of the PVB resin 1320 and the procurement cost of the plasticizer etc. 1322,
The sum of the procurement cost of recycled materials 1330 and the procurement cost of PVB resin and plasticizers 1332,
By calculating the difference between the two, the effect of reducing material procurement costs by using recycled materials is calculated.

In step S1409, the information processing unit 320 determines whether the inspection of the recyclable material of the film type being processed has been completed. If it is determined in step S1409 that the inspection has not been completed (NO in step S1409), the information processing unit 320 waits until the inspection is completed.

On the other hand, if it is determined in step S1411 that an order for an interlayer film for laminated glass of the film type being processed has been received (YES in step S1411), the information processing unit 320 proceeds to step S1412.

In step S1412, the information processing unit 320 acquires price information (information ID = PR2), stores it in the input information storage unit 330, and outputs the acquired price information (information ID = PR2).

In step S1413, the information processing unit 320 reads and outputs inspection information (information ID = IN1) for the recyclable material of the film type to be processed from the input information storage unit 330.

In step S1414, the information processing unit 320 determines whether an interlayer film for laminated glass of the film type being processed has been manufactured.

On the other hand, if it is determined in step S1414 that it has been manufactured (YES in step S1414), the information processing unit 320 proceeds to step S1415.

In step S1416, the information processing unit 320 acquires the recycled material content and virgin material content when the interlayer film for laminated glass of the film type being processed was manufactured, and stores these in the input information storage unit 330.

As a result, according to the first embodiment, it is possible to clearly determine the environmental impact reduction effect of recycling interlayer films for laminated glass using the recycling system 100.

Furthermore, the server device 310 according to the first embodiment
- Calculate and output expiration information indicating the number of days elapsed and expiration date of recycled materials collected for each membrane type.
- Based on shipping information, the stock amount of cut-out interlayer film for laminated glass for each film type at the delivery destination is calculated and the stock information is output.

In this way, the server device 310 according to the first embodiment is configured to manage recycled materials. This makes it easier to create a production plan for manufacturing interlayer films for laminated glass using recycled materials.

Second Embodiment
Although the first embodiment does not mention the number of times that a recyclable material can be recycled, it is expected that the number of times that a recyclable material can be recycled will be multiple according to the recycle system 100. Therefore, the information processing unit 320 of the server device 310 may be configured to manage the number of times that a recyclable material can be recycled.

For example, the information processing unit 320 of the server device 310 calculates the following as the composition of the recycled materials contained in the collected recycled materials based on the past input information (specifically, past shipping information) stored in the input information storage unit 330:
- The proportion of recycled materials that have been recycled only once,
- The proportion of recycled materials that have been recycled twice,
- The proportion of recycled materials that have been recycled three times,
Furthermore, the information processing unit 320 of the server device 310 may cause the output unit 830 to output the composition of recycled materials calculated by the calculation unit 820 (the proportion of recycled materials for each number of times recycled).

The composition of recycled materials (the proportion of recycled materials per recycling count) output by the output unit 830 may be reflected in the content ratio when, for example, recovered recycled materials and virgin materials are blended to manufacture an interlayer film for laminated glass.

In this way, the server device 310 according to the second embodiment is configured to manage the number of times recycled. As a result, according to the second embodiment, it becomes possible to appropriately plan production when manufacturing interlayer films for laminated glass using recycled materials.
