Summary of the Invention

Problems to be Solved by the Invention

[0005] However, a system that clearly shows the amount of carbon dioxide absorbed and fixed in wall panels, that is, the amount of carbon dioxide fixed, has not been constructed in wall panel manufacturing. In order to promote the amount of carbon dioxide fixed in wall panel manufacturing, it is necessary to clearly grasp the amount of carbon dioxide fixed to wall panels in the wall panel manufacturing line.

[0006] An object of the present invention is to provide a system that can calculate the amount of carbon dioxide fixed to wall panels in a wall panel manufacturing line. [Means for solving the problem]

[0007] According to the present invention, a system is provided for calculating the amount of carbon dioxide fixed to wall panels in a wall panel manufacturing line that uses hydraulic material and wood reinforcement as raw materials. This system comprises a database, a raw material calculation unit, and a process calculation unit.

[0008] The database contains a raw materials file and a process file. The raw materials file contains data on the amount of domestically produced processed wood used as wood reinforcement material in the wall panel manufacturing line. The process file contains at least one of the following: process environment data, which is information on carbon dioxide in the wall panel manufacturing line, and wall panel data, which is information on wall panels at the manufacturing stage.

[0009] The raw material calculation unit calculates the first fixed amount, which is the amount of carbon dioxide fixed to the wall panels by the use of domestically produced wood products, based on the usage data of domestically produced wood products and the carbon content of domestically produced wood products.

[0010] The process calculation unit calculates a second fixed amount, which is the amount of carbon dioxide absorbed and fixed in the wall panels during the wall panel manufacturing line, based on at least one of the process environment data and the wall panel data.

[0011] According to the system of the present invention, the amount of carbon dioxide fixed in the wall panel manufacturing line is calculated as a first fixed amount, which is the amount of carbon dioxide fixed in the wall panel by domestically produced wood processed materials used as raw materials for the wall panel, and a second fixed amount, which is the amount of carbon dioxide absorbed and fixed in the wall panel during the wall panel manufacturing line. Therefore, it is suitable for understanding the amount of carbon dioxide fixed in the wall panel manufacturing line.

[0012] Preferably, the process environment data includes carbon dioxide data in the atmosphere of the wall panel manufacturing line, and the wall panel data includes at least one of the mass data of the wall panel at the manufacturing stage and the analysis data of the wall panel at the manufacturing stage. The process calculation unit calculates a second fixed amount based on at least one of the carbon dioxide data in the atmosphere, the mass data of the wall panel, and the analysis data of the wall panel.

[0013] In this configuration, the amount of carbon dioxide fixed to the wall panel can be calculated as at least one of the following: the decrease in carbon dioxide in the process atmosphere, the increase in the mass of the wall panel due to the absorption and fixation of carbon dioxide by the wall panel, or the increase in calcium carbonate in the wall panel due to the absorption and fixation of carbon dioxide by the wall panel. This configuration is suitable for understanding the amount of carbon dioxide fixed in the wall panel manufacturing line.

[0014] In a wall panel manufacturing line, granular material with fixed carbon dioxide can be used as a raw material. In this case, the raw material file includes data on the amount of granular material used and data on the amount of carbon dioxide fixed by the granular material. The raw material calculation unit can calculate a third fixed amount, which is the amount of carbon dioxide fixed to the wall panel by the use of the granular material, based on the data on the amount of granular material used and the amount of carbon dioxide fixed by the granular material.

[0015] When using granular material with fixed carbon dioxide as a raw material, the resulting wall panels will have the carbon dioxide contained in the granular material fixed within them. Therefore, the raw material calculation unit is suitable for determining the amount of carbon dioxide fixed in the wall panels on the wall panel manufacturing line by calculating the amount of carbon dioxide fixed in the wall panels due to the use of granular material.

[0016] A wall panel manufacturing line may include an energy supply process that supplies energy to the wall panel manufacturing line by burning fuel. In this case, the database may include an emission file containing fuel usage data in the energy supply process, fuel unit calorific value data, and fuel emission factor data. The system may also include an emission calculation unit that calculates the amount of carbon dioxide emitted in the energy supply process based on the fuel usage data, fuel unit calorific value data, and fuel emission factor data.

[0017] When a wall panel manufacturing line includes an energy supply process that supplies energy to each process by burning fuel, the emission calculation unit can calculate the carbon dioxide emissions from the energy supply process as the carbon dioxide emissions from the wall panel manufacturing line, making it suitable for understanding the carbon dioxide emissions from the wall panel manufacturing line. By understanding the carbon dioxide emissions, it is possible to determine whether the current carbon dioxide sequestration rate is sufficient.

[0018] The emissions file may include at least one of the following: electrical data relating to electricity supplied from outside the energy supply process, or thermal data relating to heat supplied from outside the energy supply process. The electrical data may include electricity usage data and electricity emission factor data. The thermal data may include heat usage data and heat emission factor data. The emissions calculation unit may perform at least one of the following: calculate carbon dioxide emissions from electricity use based on electricity usage data and electricity emission factor data, or calculate carbon dioxide emissions from heat use based on heat usage data and heat emission factor data.

[0019] This configuration is suitable for understanding carbon dioxide emissions from the use of electricity and heat when a wall panel manufacturing line receives at least one of either electricity or heat from outside the energy supply process. By understanding carbon dioxide emissions, it is possible to determine whether the current carbon dioxide sequestration rate is sufficient.

[0020] Furthermore, the emission file may contain transportation data related to the transport of wall panels. The emission calculation unit can calculate the amount of carbon dioxide emissions from the transport based on the transportation data.

[0021] This configuration is suitable for understanding the carbon dioxide emissions generated by the transportation of wall panels. By understanding the carbon dioxide emissions, it is possible to determine whether the current carbon dioxide sequestration rate is sufficient.

[0022] Preferably, the transportation data includes transportation fuel usage data and carbon dioxide emission factor data. The emission calculation unit calculates the amount of carbon dioxide emissions from transportation based on the transportation fuel usage data and the carbon dioxide emission factor data.

[0023] Such a configuration is suitable for more accurately grasping the amount of carbon dioxide emissions from the transportation of wall panels. By accurately grasping the amount of carbon dioxide emissions, it is possible to determine whether the current amount of carbon dioxide fixation is sufficient.

[0024] Preferably, the system includes a comparison unit that compares the fixed amount with the amount of carbon dioxide emissions.

[0025] By including the comparison unit, it is suitable for comparing the fixed amount of carbon dioxide with the amount of carbon dioxide emissions and determining whether the fixed amount of carbon dioxide is greater than the amount of carbon dioxide emissions.

For example, if the network is the internet, communication can be performed using protocols such as TCP / IP.

[0045] A wall panel manufacturing line in one embodiment of the system of the present invention comprises a raw material supply step, a raw material mixing step, a molding step, and a curing and storage step.

[0046] In the raw material supply process, raw materials are supplied to the wall panel manufacturing line. In this embodiment, hydraulic material and wood reinforcing material are supplied as raw materials.

[0047] Examples of hydraulic materials include cement, gypsum, and slag. Examples of cement include ordinary Portland cement, rapid-hardening Portland cement, alumina cement, blast furnace cement, and fly ash cement. Examples of gypsum include anhydrous gypsum, hemihydrate gypsum, and dihydrate gypsum. Examples of slag include blast furnace slag and converter slag. One type of hydraulic material may be used, or two or more types of hydraulic materials may be used.

[0048] Examples of wood-based reinforcing materials include wood powder, wood wool, wood chips, wood pulp, wood fibers, and wood fiber bundles obtained by processing domestic timber, as well as wood powder, wood wool, wood chips, wood pulp, wood fibers, and wood fiber bundles obtained by processing foreign timber, and recycled paper. One type of wood-based reinforcing material may be used, or two or more types of wood-based reinforcing materials may be used.

[0049] Furthermore, other raw materials may be included. Examples of other raw materials include siliceous materials, admixtures, reinforcing fibers, waterproofing agents, and hardening agents. Examples of siliceous materials include silica sand, silica powder, silica powder, coal ash, fly ash, and diatomaceous earth. One type of siliceous material may be used, or two or more types of siliceous materials may be used.

[0050] Examples of admixtures include mica, paper mill sludge incineration ash, silica fume, wollastonite, magnesium hydroxide, aluminum hydroxide, vermiculite, sepiolite, xonotlite, kaolinite, zeolite, expanded polystyrene beads, microspheres, perlite, fly ash balloons, shirasu balloons, expanded shale, expanded clay, and calcined diatomaceous earth. One type of admixture may be used, or two or more types of admixtures may be used.

[0051] Examples of reinforcing fibers include bamboo fiber, hemp fiber, bagasse, rice husk, rice straw, synthetic fibers such as polyester fiber, polyamide fiber, acrylic fiber, polyvinylidene chloride fiber, acetate fiber, polypropylene fiber, polyethylene fiber, and vinylon fiber, as well as glass fiber, carbon fiber, ceramic fiber, and rock wool.

One type of waterproofing agent or curing agent may be used, or two or more types may be used.

[0053] In the raw material mixing process, the supplied raw materials are mixed in predetermined proportions to produce a raw material mixture. In this embodiment, for example, hydraulic material is mixed in proportions of 30-70%, wood reinforcing material in proportions of 3-30%, siliceous material in proportions of 0-60% by mass, and admixture in proportions of 1-65% by mass. In addition, a predetermined amount of water is mixed in the raw material mixing process as needed. Furthermore, within a range that does not affect the physical properties, carbon dioxide can be blown into the raw materials while mixing to produce a raw material mixture in which carbon dioxide has been absorbed and fixed. The blowing of carbon dioxide is carried out in a sealed apparatus.

[0054] In the molding process, a molded product is manufactured by molding a raw material mixture. Methods for obtaining a molded product include mixing the raw material mixture with water to form a slurry and then papermaking, extrusion molding of the raw material mixture, a dry molding method in which the raw material mixture is sprayed and deposited, and a casting method in which the raw material mixture is poured into a mold. The resulting molded product is molded by applying pressure as needed. In addition, carbon dioxide can be blown into the molded product during the molding process to the extent that it does not affect the physical properties, allowing the carbon dioxide to be absorbed and fixed into the molded product. The blowing of carbon dioxide is carried out in a sealed apparatus.

In the curing and storage process, the molded product can be exposed to an environment in a sealed apparatus where a constant amount of carbon dioxide is supplied, allowing the molded product to absorb and fix carbon dioxide.

[0056] The wall panels are manufactured through the above-described raw material supply process, raw material mixing process, molding process, and curing / storage process.

[0057] Next, the usage of the system in this embodiment and the operation of the terminal device and server device will be described in detail. Figure 5 is a flowchart that schematically shows the processing flow when calculating the amount of carbon dioxide fixed in a wall panel manufacturing line using this system.

[0058] Trees absorb carbon dioxide through photosynthesis as they grow, and when wood products are used as raw materials for wall panels, carbon dioxide is fixed in the wall panels. Furthermore, the amount of carbon dioxide fixed needs to be a value for the country where the wall panels are manufactured. Therefore, in this embodiment, first, the raw material calculation unit 203 calculates the amount of carbon dioxide fixed in the wall panels based on the use of domestically produced wood products (step S11). The raw material data in the database 210 includes data on the raw material name, raw material code, and carbon content of domestically produced wood products for each raw material, and the raw material usage data includes data on the raw material name, raw material code, and usage amount of each raw material. For the same raw material name or the same raw material code, the raw material calculation unit 203 calculates the amount of carbon dioxide fixed based on the use of domestically produced wood for each raw material by multiplying the raw material usage amount in the raw material usage data by the carbon content in the raw material data and the conversion factor of 44 / 12. Furthermore, the raw material calculation unit 203 calculates the sum of the calculated amounts of carbon dioxide fixed based on the use of domestically produced wood for each raw material. The raw material calculation unit 203 records the total amount of carbon dioxide fixed calculated as the amount of carbon dioxide fixed in the wall panel manufacturing line based on the use of domestically produced wood products, along with the date of raw material use, in the storage unit 201 of the server device. The amount of carbon dioxide fixed calculated in step S11 is the first fixed amount.

[0059] In calculating the amount of carbon dioxide sequestered based on the use of domestically produced wood products, the amount of carbon dioxide sequestered based on the use of domestically produced wood for each raw material may be calculated by multiplying the carbon content of the domestically produced wood product by the amount of the raw material used, or domestically produced wood products may be extracted and the amount of carbon dioxide sequestered may be calculated only for the extracted raw materials. The extraction of domestically produced wood products is performed by the raw material calculation unit 203 extracting raw materials for which a numerical value has been entered in the carbon content data of domestically produced wood products as domestically produced wood products, by providing an identification code for domestically produced wood products, and the raw material calculation unit 203 extracting the corresponding items.

[0060] After completing the process in step S11, the process calculation unit 204 calculates the amount of carbon dioxide fixed in the process (step S12). Since the process file 222 contains at least one of the process environment data, wall panel mass data, and wall panel analysis data for the wall panel manufacturing line, the process calculation unit 204 calculates the amount of carbon dioxide fixed based on at least one of the process environment data, wall panel mass data, and wall panel analysis data in the process file 222. The amount of carbon dioxide fixed calculated in step S12 is the second fixed amount.

[0061] In calculating the amount of carbon dioxide fixed based on process environmental data, the process calculation unit 204 calculates the amount of carbon dioxide reduced during the wall panel manufacturing process based on the process environmental data, and uses this reduction amount as the amount of carbon dioxide fixed.

[0062] Each stage of the manufacturing line is equipped with a device, and the process environment data for each piece of manufacturing equipment includes data such as the wall panel production date, measurement location, measurement time, measured value of carbon dioxide in the atmosphere, volume of the device, location of carbon dioxide supply, and amount of carbon dioxide supply.

[0063] The measurement points are inside the apparatus, and the measured value of carbon dioxide in the atmosphere is the carbon dioxide value inside the apparatus, measured by the carbon dioxide concentration in the atmosphere within the apparatus. For example, there are five measurement points, and the measured value of carbon dioxide in the atmosphere is the carbon dioxide concentration in the atmosphere at five locations inside the apparatus. The process environment data also includes the volume of the apparatus (D130) and the amount of carbon dioxide supplied into the apparatus (D140).

[0064] The process calculation unit 204 extracts carbon dioxide measurements at the same location based on the measurement location and time. Specifically, the process calculation unit 204 extracts carbon dioxide concentrations (D111~115) at five locations before carbon dioxide supply (before wall panel manufacturing) and carbon dioxide concentrations (D121~125) at five locations after wall panel manufacturing, based on the measurement location and time. The process calculation unit 204 then calculates the amount of carbon dioxide in the equipment before carbon dioxide supply (before wall panel manufacturing) (D150) by multiplying the average value of the carbon dioxide concentrations (D111~115) by the volume of the equipment (D130) and a coefficient of 44 / 22.4. Furthermore, the process calculation unit 204 calculates the amount of carbon dioxide in the equipment after wall panel manufacturing (D160) by multiplying the average value of the carbon dioxide concentrations (D121~125) by the volume of the equipment (D130) and a coefficient of 44 / 22.4. Furthermore, the amount of carbon dioxide lost in the device is calculated by subtracting the amount of carbon dioxide lost in the device after the wall panel is manufactured (D160) from the sum of the amount of carbon dioxide supplied into the device (D140) and the amount of carbon dioxide lost in the device before the supply of carbon dioxide (before the wall panel is manufactured) (D150). This reduced amount is then defined as the amount of carbon dioxide fixed in the device.

[0065] In calculating the amount of carbon dioxide fixed based on wall panel mass data, the process calculation unit 204 calculates the increase in the amount of moisture removed from the wall panel during the manufacturing process, and uses this increase as the amount of carbon dioxide fixed.

[0066] Equipment is installed at each stage of the manufacturing line, and the wall panel mass data includes data such as the wall panel production date, measurement location, measurement time, moisture content of the wall panel during the manufacturing stage, and the mass of the wall panel during the manufacturing stage.

[0067] Measurement points include the receiving port where the wall panels in the manufacturing stage are received into the apparatus, and the discharge port where the wall panels in the manufacturing stage are discharged outside the apparatus. In this case, the mass of the wall panels in the manufacturing stage is the mass of the wall panels at the receiving port (D211) and the mass of the wall panels at the discharge port (D221). The moisture content of the wall panels in the manufacturing stage is the moisture content of the wall panels at the receiving port (D212) and the moisture content of the wall panels at the discharge port (D222). In the raw material mixing process, the apparatus receives each raw material and water before mixing, and the sum of the masses of each raw material and water to be mixed is taken as the mass of the wall panels in the manufacturing stage at the receiving port (D211), and the mass of the water added is taken as the moisture content of the wall panels at the receiving port (D212).

[0068] The process calculation unit 204 calculates the increase in the wall plate in the apparatus by subtracting the difference between the mass of the wall plate at the receiving port (D211) and the moisture content of the wall plate at the receiving port (D212), and the moisture content of the wall plate at the discharge port (D222), from the mass of the wall plate at the discharge port (D221), and takes this increase as the amount of carbon dioxide fixed.

[0069] In calculating the amount of carbon dioxide fixed based on wall panel analysis data, the process calculation unit 204 calculates the increase in calcium carbonate in the wall panel during the manufacturing stage, and uses this increase as the amount of carbon dioxide fixed.

[0070] Equipment is installed at each stage of the manufacturing line, and the analysis data for the wall panels includes data such as the wall panel production date, measurement location, measurement time, and analysis values ​​of the wall panels at each stage of manufacturing.

[0071] As an example, measurement points include the receiving port where the wall panels in the manufacturing stage are received into the apparatus, and the discharge port where the wall panels in the manufacturing stage are discharged outside the apparatus. In this case, the analytical values ​​for the wall panels in the manufacturing stage are the calcium carbonate content at the receiving port (D311), obtained by taking a sample of the wall panel at the receiving port and performing differential thermal balance analysis, and the calcium carbonate content at the discharge port (D312), obtained by taking a sample of the wall panel at the discharge port and performing differential thermal balance analysis. In the raw material mixing process, since the raw materials are received into the apparatus before mixing, the calcium carbonate content at the receiving port (D311) is the sum of the values ​​obtained by multiplying the calcium carbonate content obtained by differential thermal balance analysis of each raw material by the amount of each raw material used.

[0072] The process calculation unit 204 calculates the increase in calcium carbonate in the wall plate of the apparatus by subtracting the calcium carbonate content at the inlet (D311) from the calcium carbonate content at the outlet (D312), and uses this increase as the amount of carbon dioxide fixed.

[0073] The process calculation unit 204 calculates the amount of carbon dioxide fixed for each device. The process calculation unit 204 records the amount of carbon dioxide fixed and the production date of the wall panels in the storage unit 201 of the server device. The sum of the amounts of carbon dioxide fixed in each device is the second fixed amount. The process calculation unit 204 can also use the average value of the values ​​calculated based on process environment data, wall panel mass data, and wall panel analysis data as the amount of carbon dioxide fixed.

[0074] After completing the process in step S12, the amount of carbon dioxide fixed is displayed (step S13). An example of the screen displaying the amount of carbon dioxide fixed is shown in Figure 6.

[0075] Figure 6 shows the amount of carbon dioxide fixed for each of the processes 1-4 and the subtotal. Process 1 is the raw material supply process, process 2 is the raw material mixing process, process 3 is the molding process, and process 4 is the curing and storage process.

[0076] Step 1 displays the amount of carbon dioxide fixed (first fixed amount) calculated by the raw material calculation unit 203. Step 2 displays the amount of carbon dioxide fixed in the raw material mixing process, calculated by the process calculation unit 204. Step 3 displays the amount of carbon dioxide fixed in the molding process, calculated by the process calculation unit 204. Step 4 displays the amount of carbon dioxide fixed in the curing and storage process, calculated by the process calculation unit 204. The subtotal displays the sum of the amount of carbon dioxide fixed calculated by the raw material calculation unit 203 and the amount of carbon dioxide fixed calculated by the process calculation unit 204. The relationship between the amount of carbon dioxide fixed calculated by the raw material calculation unit 203 and the amount of carbon dioxide fixed calculated by the process calculation unit 204 is based on the raw material usage date and the wall panel production date. That is, data where the raw material usage date and the wall panel production date are the same is extracted and displayed on the screen in Figure 6.

[0077] As described above, the system of this embodiment calculates the amount of carbon dioxide fixed in the wall panel manufacturing line by the amount of carbon dioxide fixed in the wall panel by the domestically produced wood processed material used as the raw material for the wall panel, and the amount of carbon dioxide fixed in the wall panel manufacturing line. Therefore, it is suitable for understanding the amount of carbon dioxide fixed in the wall panel manufacturing line. Furthermore, as shown in Figure 6, it is also possible to understand the amount of carbon dioxide fixed in each process and the total amount of carbon dioxide fixed in the wall panel manufacturing line.

[0078] In a second embodiment of the system of the present invention, as a raw material, wall panel scraps are crushed into granules, which are then treated in a carbon dioxide atmosphere to absorb and fix carbon dioxide. The amount of carbon dioxide fixed to the wall panel by using these granules is also determined.

[0079] In the second embodiment, the system configuration is the same as in Figure 1, and the internal configuration of the server device and database is the same as in Figure 2.

[0080] Figure 7 schematically shows the file structure in the server device's database in the second embodiment. The raw material file 221 differs from the raw material file 221 in Figure 3 in that it includes the amount of carbon dioxide fixed by the raw material in the raw material data, but is otherwise the same as in Figure 3. The amount of carbon dioxide fixed by the raw material is the amount of carbon dioxide absorbed and fixed by the raw material during the manufacturing process. The amount of carbon dioxide fixed by the raw material is a value calculated using the same calculation method as the process calculation unit, from process environment data, raw material mass data, raw material analysis data, etc., during the manufacturing of the raw material. Domestic wood processed products do not undergo any process to absorb and fix carbon dioxide during the manufacturing of the raw material, and therefore the amount of carbon dioxide fixed by the raw material is zero.

[0081] In the raw material mixing process, granular material with fixed carbon dioxide is mixed with other raw materials to produce a raw material mixture. The proportion of granular material with fixed carbon dioxide is, for example, 1 to 65% by mass.

[0082] Figure 8 is a flowchart illustrating the process for calculating the amount of carbon dioxide fixed in a wall panel manufacturing line using this system. The flowchart in Figure 8 differs from the flowchart in Figure 5 in that the raw material calculation unit calculates the amount of carbon dioxide fixed to the wall panel based on the use of granular material (step S22).

[0083] In Figure 8, the raw material calculation unit 203 extracts data based on the granular material name or the raw material code of the granular material, and calculates the amount of carbon dioxide fixed by using the granular material by multiplying the amount of raw material used in the raw material usage data by the amount of carbon dioxide fixed by the raw material in the raw material data. Furthermore, the raw material calculation unit 203 records the amount of carbon dioxide fixed based on the use of the granular material, along with the date of use, in the storage unit 201 of the server device. The amount of carbon dioxide fixed calculated in step S22 is the third fixed amount.

[0084] Furthermore, the amount of carbon dioxide fixed by each raw material may be calculated not only for granular materials but also for each individual raw material. In calculating the amount of carbon dioxide fixed for each raw material, the amount of carbon dioxide fixed for each raw material may be calculated by multiplying the amount of carbon dioxide fixed by the amount of raw material used for all raw materials, or raw materials that fix carbon dioxide may be extracted and the amount of carbon dioxide fixed may be calculated only for the extracted raw materials. Examples of extracting raw materials that fix carbon dioxide include extracting raw materials for which a numerical value has been entered for the amount of carbon dioxide fixed, or assigning an identification code to raw materials that fix carbon dioxide and extracting the corresponding items. The raw material calculation unit 203 calculates the sum of the calculated amounts of carbon dioxide fixed for each raw material and records it in the storage unit 201 of the server device along with the date of use of the raw material.

[0085] In this embodiment as well, the amount of carbon dioxide fixed is displayed on the screen shown in Figure 6. However, in this embodiment, step 1 displays the sum of the amount of carbon dioxide fixed based on the use of domestically produced wood processed materials (first fixed amount) and the amount of carbon dioxide fixed due to the use of carbonation-treated raw materials (third fixed amount), which are calculated by the raw material calculation unit. Otherwise, it is the same as in the first embodiment.

[0086] As described above, the system of this embodiment calculates the amount of carbon dioxide fixed in the wall panel manufacturing line by the amount of carbon dioxide fixed in the wall panel by the domestic wood processed materials used as raw materials for the wall panel, the amount of carbon dioxide fixed in the wall panel by the use of carbonation-treated raw materials, and the amount of carbon dioxide fixed in the wall panel manufacturing line. Therefore, it is suitable for understanding the amount of carbon dioxide fixed in the wall panel manufacturing line. It is also possible to understand the amount of carbon dioxide fixed in each process and the total amount of carbon dioxide fixed in the wall panel manufacturing line.

[0087] In a third embodiment of the present invention, in addition to the second embodiment, the wall panel manufacturing line includes an energy supply process that supplies energy such as electricity and heat to each process by burning fuel such as coal, gasoline, or heavy oil. The system also includes an emission calculation unit that calculates the carbon dioxide emissions from the energy supply process as the carbon dioxide emissions from the wall panel manufacturing line, and an emission file that has information on the energy supply process in a database.

[0088] Figure 9 is a schematic diagram illustrating an example of the system configuration according to this embodiment. In Figure 9, a terminal device is installed in the energy supply process, and this terminal device is connected to a server device via a network. The rest is the same as in Figure 1.

[0089] Figure 10 is a functional block diagram schematically showing the internal configuration of the server device and database in Figure 9. The server device differs from the server device in Figure 2 in that it further includes an output calculation unit 205 and an output file 223 in the database 210, but otherwise it is the same as the server device in Figure 2. The configuration of the terminal device is the same as in Figure 4.

[0090] Figure 11 schematically shows the file structure within database 210. Database 210 differs from the database in Figure 7 in that it includes emission file 223, but is otherwise the same. Emission file 223 contains fuel data. The fuel data includes the wall panel production date, the amount of fuel used in the energy supply process, the unit calorific value of the fuel, and the fuel emission coefficient. The unit calorific value of the fuel is preferably obtained at the time of fuel purchase, but a national average default value can also be used. The fuel emission coefficient is a value that indicates the amount of carbon dioxide emitted when the activity is carried out, and can be calculated by multiplying the carbon content per unit weight or volume of the fuel by a coefficient of 44 / 12 and dividing the resulting value by the unit calorific value per unit weight or volume, but a national average default value may also be used.

[0091] Figure 12 is a flowchart illustrating the process flow when using this system to calculate the amount of carbon dioxide fixed and the amount of carbon dioxide emitted in a wall panel manufacturing line. The flowchart in Figure 12 differs from the flowchart in Figure 8 in that, after the process calculation unit calculates the amount of carbon dioxide fixed in the process (step S33), the emission calculation unit calculates the amount of carbon dioxide emitted based on the data in the emission file (step S34), and the amount of carbon dioxide fixed and emitted is displayed (step S35).

[0092] In step S34 of Figure 12, the emission calculation unit 205 calculates the amount of carbon dioxide emissions in the energy supply process by multiplying the amount of fuel used in the energy supply process by the unit calorific value of the fuel and the emission coefficient of the fuel. Furthermore, the emission calculation unit 205 records the calculated amount of carbon dioxide emissions, along with the wall panel production date, in the storage unit 201 of the server device.

[0093] Figure 13 shows an example of a screen displaying the amount of carbon dioxide sequestration obtained from the flowchart in Figure 12. In Figure 13, there are columns for the energy supply process and carbon dioxide emissions. The carbon dioxide emissions are displayed where the energy supply process column and the carbon dioxide emissions column intersect. The rest is the same as in Figure 6.

[0094] As described above, the system of this embodiment calculates the amount of carbon dioxide fixed in the wall panel manufacturing line by the amount of carbon dioxide fixed in the wall panel by the domestic wood processed materials used as raw materials for the wall panel, the amount of carbon dioxide fixed in the wall panel by the use of carbonized raw materials, and the amount of carbon dioxide fixed in the wall panel manufacturing line. Therefore, it is suitable for understanding the amount of carbon dioxide fixed in the wall panel manufacturing line. It is also possible to understand the amount of carbon dioxide fixed in each process and the total amount of carbon dioxide fixed in the wall panel manufacturing line. Furthermore, it is suitable for understanding the amount of carbon dioxide emitted due to energy supply in the wall panel manufacturing line. By understanding the amount of carbon dioxide emitted, it is possible to determine whether the current amount of carbon dioxide fixed is sufficient.

[0095] In the fourth embodiment of the present invention, in addition to the third embodiment, each process in the wall panel manufacturing line receives electricity and heat from an external source, and the system calculates the amount of carbon dioxide emitted due to the use of electricity and heat in each process as the total carbon dioxide emissions from the wall panel manufacturing line. The system also includes a comparison unit that compares the amount of carbon dioxide fixed with the amount emitted.

[0096] Figure 14 is a functional block diagram schematically showing the internal configuration of the server device and database in the fourth embodiment. The server device differs from the server device in Figure 10 in that it further includes a comparison unit 206, but is otherwise the same as the server device in Figure 10. The configuration of the terminal device is the same as in Figure 4.

[0097] Figure 15 schematically shows the file structure within database 210. Database 210 contains electrical data and thermal data in emission file 223. The electrical data includes the wall panel production date, electricity usage, and the electrical emission factor. The thermal data includes the wall panel production date, heat usage, and the thermal emission factor. The rest is the same as in Figure 11. For the electrical emission factor, it is preferable to use the emission factor provided by the electricity company, but the national average default value can also be used. For the thermal emission factor, it is preferable to use the emission factor provided by the heat company, but the national average default value can also be used.

[0098] Figure 16 is a flowchart illustrating the process for calculating the amount of carbon dioxide sequestration and carbon dioxide emissions from a wall panel manufacturing line using this system. The flowchart in Figure 16 differs from the flowchart in Figure 12 in that the emission calculation unit 205 calculates the amount of carbon dioxide emissions based on the electrical data and thermal data of the emission file 223 (step S45).

[0099] In step S45 of Figure 16, the emission calculation unit 205 calculates the amount of carbon dioxide emitted from electricity by multiplying the amount of electricity used by the electricity emission coefficient. The emission calculation unit 205 also calculates the amount of carbon dioxide emitted from heat by multiplying the amount of heat used by the heat emission coefficient. Furthermore, the emission calculation unit 205 records the calculated amount of carbon dioxide emitted, along with the wall panel production date, in the storage unit 201 of the server device.

[0100] Figure 17 shows an example of a screen displaying the amount of carbon dioxide fixed obtained from the flowchart in Figure 16. In Figure 17, there are columns for the introduction of electricity from an external source, the introduction of heat from an external source, and the amount of carbon dioxide fixed minus the amount of carbon dioxide emitted. The column for the introduction of electricity from an external source displays the amount of carbon dioxide emitted calculated based on the electricity data. The column for the amount of carbon dioxide fixed minus the amount of carbon dioxide emitted is calculated by the comparison unit 206 and displayed.

[0101] As described above, the system of this embodiment calculates the amount of carbon dioxide fixed in the wall panel manufacturing line by the amount of carbon dioxide fixed in the wall panel by the domestic wood processed materials used as raw materials for the wall panel, the amount of carbon dioxide fixed in the wall panel by the use of carbonized raw materials, and the amount of carbon dioxide fixed in the wall panel manufacturing line. Therefore, it is suitable for understanding the amount of carbon dioxide fixed in the wall panel manufacturing line. It is also possible to understand the amount of carbon dioxide fixed in each process and the amount of carbon dioxide fixed in the entire wall panel manufacturing line. Furthermore, it is suitable for understanding the carbon dioxide emissions from energy supply, electricity use, and heat use in the wall panel manufacturing line. Moreover, it is suitable for determining whether the amount of carbon dioxide fixed exceeds the amount of carbon dioxide emitted.

[0102] In the fifth embodiment of the present invention, in addition to the fourth embodiment, the emission file contains transportation data relating to the transportation of wall panels, and the emission calculation unit calculates the amount of carbon dioxide emitted due to transportation based on the transportation data.

[0103] The processes and server equipment of the wall panel manufacturing line in the fifth embodiment are the same as in the fourth embodiment.

[0104] Figure 18 schematically shows the file structure within database 210. Database 210 contains transportation data in emission file 223. The transportation data includes the wall panel production date, fuel usage, and carbon dioxide emission coefficient. The rest is the same as in Figure 15.

[0105] Figure 19 is a flowchart illustrating the process for calculating the amount of carbon dioxide sequestration and carbon dioxide emissions from a wall panel manufacturing line using this system. The flowchart in Figure 19 differs from the flowchart in Figure 16 in that the emission calculation unit 205 calculates the amount of carbon dioxide emissions based on the transport data in the emission file 223 (step S56).

[0106] In step S56 of Figure 19, the emission calculation unit 205 calculates the amount of carbon dioxide emitted during transportation by multiplying the amount of fuel used by the carbon dioxide emission factor. The emission calculation unit 205 records the calculated amount of carbon dioxide emitted, along with the wall panel production date, in the storage unit 201 of the server device.

[0107] Figure 20 shows an example of a screen displaying the amount of carbon dioxide sequestration obtained from the flowchart in Figure 19. In Figure 20, a section for transport is provided. The transport section displays the amount of carbon dioxide emissions calculated based on the transport data.

[0108] As described above, the system of this embodiment calculates the amount of carbon dioxide fixed in the wall panel manufacturing line by the amount of carbon dioxide fixed in the wall panel by the domestic wood processed materials used as raw materials for the wall panel, the amount of carbon dioxide fixed in the wall panel by the use of carbonized raw materials, and the amount of carbon dioxide fixed in the wall panel manufacturing line. Therefore, it is suitable for understanding the amount of carbon dioxide fixed in the wall panel manufacturing line. It is also possible to understand the amount of carbon dioxide fixed in each process and the amount of carbon dioxide fixed in the entire wall panel manufacturing line. Furthermore, it is suitable for understanding the carbon dioxide emissions from energy supply, electricity use, heat use, and transportation in the wall panel manufacturing line. Moreover, it is suitable for determining whether the amount of carbon dioxide fixed exceeds the amount of carbon dioxide emitted.

[0109] Although the system of the present invention has been described above with reference to specific embodiments, the present invention is not limited to these. Those skilled in the art can make various changes and improvements to the configuration and function of the invention according to each of the above embodiments without departing from the spirit of the present invention.

[0110] For example, the process environment data may include pressure and temperature data within the apparatus, and the process calculation unit may use the pressure and temperature data to calculate the amount of carbon dioxide reduction. Alternatively, the process environment data may include correlation data between the carbon dioxide concentration in the atmosphere within the apparatus and the amount of carbon dioxide fixed by the wall panels during the manufacturing stage, and the process calculation unit may calculate the amount of carbon dioxide absorbed and fixed by the wall panels based on the measured carbon dioxide concentration within the apparatus and the correlation data.

[0111] Transportation data includes transportation distance and fuel consumption. The emission calculation unit may calculate carbon dioxide emissions from transportation by dividing the transportation distance by the fuel consumption and then multiplying by the carbon dioxide emission factor. Alternatively, carbon dioxide emissions from transportation can also be calculated by setting a ton-kilometer emission factor for each vehicle's maximum load capacity and load rate, and multiplying the transportation ton-kilometer by the factor.
