Description

Biochar Credit Management System

[0001] This invention relates to a biochar credit management system.

[0002] Agricultural residues such as rice husks are generated in many countries, but most are incinerated, and the large amount of carbon dioxide emitted during this process poses a challenge to global environmental conservation.

[0003] For this reason, research is underway around the world to effectively utilize biochar, which is produced by carbonizing rice husks and other materials and exhibiting carbon sequestration effects in the soil. For example, Patent Document 1 discloses an apparatus for using the heat generated by incinerating rice husks to heat agricultural greenhouses and for producing rice husk biochar by steam-roasting rice husks. Patent Document 2 describes a biochar production apparatus for producing rice husk biochar on-site, such as in farmland where rice husks are generated. Rice husk biochar has soil improvement effects, improving physical properties such as water permeability, water retention, and aeration, as well as correcting acidic soil to alkaline and supplying nutrients such as phosphorus.

[0004] On the other hand, so-called "carbon credit schemes," in which countries or regions certify reductions in greenhouse gas emissions or increases in carbon absorption as "credits" in order to reduce greenhouse gas emissions, are being widely considered and implemented internationally. In a carbon credit scheme, for example, credit creators who earn credits by reducing greenhouse gas emissions can transfer credits to credit purchasers who are unable to reduce greenhouse gas emissions. Furthermore, projects that sequester carbon by applying biochar to soil are attracting attention worldwide as activities eligible for carbon credit certification.

[0005] Therefore, in this specification, "carbon credit" refers to a quantified representation of the environmental value obtained by reducing or removing greenhouse gas emissions. Furthermore, "biotincard credit" refers to a type of carbon credit created based on the long-term sequestering and storage of carbon derived from atmospheric carbon dioxide through the production and use of biotincture.

[0006] The "Carbon Credit Scheme" established in Japan, known as the J-Credit Scheme, designates eligible projects that contribute to reducing greenhouse gas emissions and increasing absorption. One of these projects is the "application of biochar to agricultural land." In the J-Credit Scheme, biochar is defined as "a solid material produced by heating biomass at temperatures exceeding 350°C under oxygen concentrations controlled to a non-combustible level," and it is recognized for its carbon sequestration effect in soil. The biomass used as raw material for this biochar (biocinic material) includes wood, livestock manure, herbs, nuts, and rice husks.

[0007] In the J-Credit scheme, as described above, J-Credit creators who implement projects that lead to reductions in greenhouse gas emissions or increases in absorption can buy and sell the J-Credits they obtain with J-Credit purchasers who wish to offset their carbon emissions. Therefore, rice farmers who produce rice husk biochar using biochar production equipment and apply it can obtain J-Credits in proportion to the amount of biochar applied, and can sell these to consumers to earn a profit.

[0008] Such carbon credit schemes are spreading internationally, and mechanisms are being put in place to allow international trading of biochar credits certified under carbon credit schemes of individual countries, regions, or organizations. Biochar credits are calculated by subtracting the emissions generated during biochar production and transportation from the amount of carbon stored through biochar application, and are generally expressed by the following formula [Equation 1]: [Equation 1] Amount of carbon stored (amount of credits) = Amount of carbon emissions reduced = (1) CO2 after project implementation 2 Storage volume - (2) CO2 emissions from project implementation 2 Emissions Here, the amounts of (1) and (2) are defined as follows: (1) CO2 emissions after project implementation 2 Storage amount = Biochar application rate (t) × Carbon content × Carbon retention rate after 100 years × 44 / 12 (2) CO2 emissions from project implementation 2 Emissions = CO2 emissions from the transportation of biochar raw materials and biochar. 2

[0009] Details of the above [Equation 1] will be described later, but for example, in the case of Japan's J-Credit scheme, in order to calculate the amount of carbon sequestration described in [Equation 1] and obtain biochar credits (J-Credits), CO 2 It is necessary to apply to a certification body (J-Credit Scheme Certification Committee) for certification of the methodology (project methodology) used to evaluate greenhouse gas reductions such as those mentioned above, and to obtain certification. The certification body verifies the validity of the project methodology, and the data and basis for the calculations are judged rigorously (see Patent Document 3).

[0010] However, not only in the J-Credit scheme, but also in carbon credit schemes established by individual countries, regions, or organizations, obtaining the necessary data for calculation (such as application rates, manufacturing conditions, and manufacturing locations) is often difficult, which places a significant burden on certification procedures that require accurate monitoring, reporting, and verification.

[0011] Furthermore, since manufacturing-related data (supply volume, firing temperature, firing time, production volume, location information, etc.) obtained from biochar production equipment is important as the basis for calculating these credits, it is necessary to collect this data using reliable methods. However, it is a significant burden for farmers to manage equipment equipped with various measuring instruments and to properly acquire and record the data.

[0012] Japanese Patent Publication No. 2022-167272, Japanese Patent Application No. 2024-026593, Japanese Patent No. 7402580

[0013] Therefore, there is a need for a system that integrates biochar production and related data collection, combining it with application data, and allowing managers to apply for biochar credits in a single process. In other words, since it is difficult for individual farmers (biocchar credit creators) to apply for biochar credits, it is effective to consolidate small-scale reduction activities by individuals and SMEs and register them as a single project with a certification body. In such projects, a system is desirable in which the project manager can handle the project registration application, monitoring reports, and certification application all at once.

[0014] On the other hand, it is preferable to install the biochar production equipment described above in the same location as the rice husk delivery area and the biochar storage area, and it is not suitable for sharing in a location far from many farmers. However, this type of biochar production equipment is expensive for individual farmers to purchase, and it is difficult to install a rice husk delivery area, a biochar storage area, and the biochar production equipment on each farm.

[0015] Therefore, the present invention provides a biochar credit management system that facilitates monitoring of the biochar production process using a biochar production system (including a biochar production apparatus) capable of measuring biochar production-related data, and allows the operator to apply for and acquire biochar credits in a single transaction. Furthermore, the present invention provides a mobile biochar production apparatus that can be transported to individual farmers, etc., and used to produce biochar on their respective farms, etc.

[0016] In this specification, unless otherwise specified, "biocal credits" certified under the carbon credit schemes of each country, region, or organization will be simply referred to as "credits," and a bioocal credit management system for acquiring and trading these "credits" will be described below.

[0048] (Transportation of the Biochar Production System) The biochar production system used in the biochar credit management system according to the present invention can have a biochar production apparatus, including at least an internal combustion chamber, fixed to a fixed transport body such as a container or trailer, and other components of the biochar production system can be loaded onto it. Therefore, the biochar production system of the present invention can be loaded and unloaded onto means of transport such as automobiles, trains, ships, and airplanes, like cargo loaded onto these fixed transport bodies, and the biochar production apparatus and the like can be transported to a destination by these means of transport. In other words, the biochar production system can be transported to a farm where biochar materials are stored, unloaded from the means of transport at the destination, and installed on-site, such as farmland, where the biochar materials are stored, along with the fixed transport body.

[0049] (Client-manufactured biochar production system) Such a biochar production system can be purchased or leased by client b or administrator a. Therefore, in a client-manufactured system purchased or leased by client b, a financially limited client b can produce biochar at a low cost by leasing the system, and biochar production-related data can be collected automatically without requiring any effort.

[0050] (Manager-managed biochar production system) On the other hand, in a manager-managed system purchased or leased by manager a, biochar material can be obtained from crops provided by client b, or biochar material can be directly provided by the manager. Then, using the purchased or leased biochar production system, biochar can be produced in bulk using client b's biochar material and transferred to client b, etc., and the credits obtained based on the amount of biochar applied by the recipient of this biochar can be managed in a collectively.

[0051] (Blockchain) Furthermore, in the biochar credit management system according to the present invention, management server A can receive signed data, with message z being the hash value of biochar production-related data, via the CPU (or device B) of the biochar production system. Management server A then verifies the authenticity of the signed data, and if authenticity is confirmed, records message z, i.e., the hash value of the biochar production-related data, on the public blockchain. Therefore, the biochar production system according to the present invention can prevent tampering with biochar production-related data received from the registered biochar production equipment.

[0052] (Rotating Kiln Type Charcoal Production Apparatus) The mobile biochar production apparatus according to the present invention is a rotary kiln type charcoal production apparatus that can be fixed to a container or trailer for transport, for example. A considerable amount of charcoal material is put into the rotary kiln, and the charcoal material is piled up inside the rotary kiln to fire the charcoal. As a result, the air barrier effect of the upper layer of piled charcoal material creates a low-oxygen state in the lower layer, resulting in firing conditions suitable for steam firing.

[0053] Furthermore, as the rotary kiln rotates, the charcoal material is lifted along the inner surface of the rotary kiln, and by adjusting the rotation speed, the upper and lower layers of the charcoal material can be replaced as needed. In addition, multiple stirring plates attached to the inner surface of the rotary kiln stir the charcoal material in the direction of its rotation, making it easy and reliable to replace the upper layer of charcoal material, which is burning at high temperature and smokeless, with the lower layer, which is in a steaming state. This eliminates uneven burning of the charcoal and ensures uniform quality.

[0054] Furthermore, in the rotary kiln type charcoal production apparatus of the present invention, a flow of air is generated from inside the rotary kiln through a chimney installed in the external combustion chamber, reducing the pressure inside the rotary kiln and allowing air to be drawn in from the outside. As a result, an airflow is created from the discharge side of the rotary kiln, passing through the inside of the rotary kiln and being exhausted from the chimney of the external combustion chamber. This air cools the charcoal produced, thus eliminating the cooling process that was conventionally required and improving the efficiency of charcoal production.

[0056] The biochar credit management system, biochar production system, and embodiments and examples of electronic commerce using the biochar credit management system according to the present invention will be described below with reference to the drawings. In the following description, biochar will be referred to as charcoal and biochar material as rice husks, but in the present invention, biochar and biochar material are not limited to charcoal and rice husks, and are not particularly limited as long as they are biochar and biochar material permitted by each carbon credit scheme. In addition, the same reference numerals will be used for the same components throughout the following drawings.

[0057] (1) Biochar credit management system

[0058] The biochar credit management system according to the present invention is a management system 1 in which, for example as shown in Figure 1, a client b who applies biochar joins a project operated by administrator a (credit certification administrator a), administrator a, which has server A, applies for credits from certification body d regarding the biochar applied by client b, and manages the certified credits.

[0059] The biochar credit management system 1 according to the present invention has a biochar production system 3 which includes a biochar production apparatus 30 purchased or leased by client b or administrator a. This biochar production system 3 is equipped with various measuring instruments 12 that measure biochar production-related data including at least the firing temperature, biochar material supply amount, biochar production amount, firing time, and biochar production location, and a CPU 11 that can communicate with the various measuring instruments 12 (see Figures 6(a) and (b)). Server A can then acquire biochar production-related data during biochar production from these various measuring instruments 12 via the CPU 11.

[0060] (Data related to biochar production, CPU) Here, the various measuring instruments 12 that constitute the biochar production system 3 described above are devices that measure biochar production-related data, including at least the firing temperature, the amount of biochar material supplied, the amount of biochar produced, the firing time, and the biochar production location. Therefore, as shown in Figures 6(a) and (b), the various measuring instruments 12 include a temperature measuring instrument 121, a supply amount measuring instrument 122, a production amount measuring instrument 123, a clock 124, and a GPS (position measuring instrument) 125, which measure these biochar production-related data, respectively.

[0061] In this biochar credit management system 1 of the present invention, a device B of a client b that applies biochar, a server A of an administrator a that obtains the biochar production-related data and submits an application form containing the biochar production-related data to a certification body d, and a device D owned by the certification body d are connected by a computer network (see Figures 1 to 3).

[0062] Then, device B transmits the biochar application rate to server A, and server A transmits the biochar production-related data obtained from the biochar production system 3 and the credit exchange application data created based on the biochar application rate to device D. Device D authenticates the credits based on this credit exchange application data and transmits the authenticated credits to server A. This "credit exchange application data" corresponds to the "application form including the biochar production-related data" mentioned above. Furthermore, it is preferable that server A manages the credits issued by this authentication body d.

[0063] (Lease) In the biochar credit management system 1 of the present invention, client b or administrator a can purchase or lease a biochar production apparatus 30 or biochar production system 3 from company e that manufactures, sells, leases, etc. (see Figure 1). Therefore, the biochar credit management system 1 of the present invention can be classified into a client-manufactured type, which is purchased or leased by client b, as shown in Figure 2, and an administrator-manufactured type, which is purchased or leased by administrator a, as shown in Figure 3. As stated above, "lease" means rental and is used to mean both rental and lease.

[0064] The following sections describe the biochar credit management system 1 according to the present invention, with a client-manufactured type described in Section (1-1) and a manager-manufactured type described in Section (1-2).

[0065] (1-1) Client-manufactured type

[0066] (Biocinyl Credit Management System) As described above, in the "client-manufactured" biocoin credit management system 1 of the present invention, client b may purchase or lease the biocoin production system 30. In this case, client b uses the biocoin production system 30 to produce biocoin and applies the produced biocoin to their own farmland, etc. (see Figure 2).

[0067] Furthermore, when producing biochar using the biochar production system 30, device B, owned by client b, receives biochar production-related data via the CPU 11 of the biochar production system 3. This CPU 11 may also be device B, and device B may directly receive and record biochar production-related data from various measuring instruments 12 during biochar production and transmit it to server A.

[0068] As described above, device B transmits biochar production-related data obtained from various measuring instruments 12 during biochar production, as well as the amount of biochar applied to farmland, etc., to server A. Upon receiving this biochar production-related data and biochar application amount, server A transmits credit exchange application data, created based on this data, to device D.

[0069] (1-2) Manager-manufactured type

[0070] (Biocinyl Credit Management System) In the "administrator-manufactured" biocoin credit management system 1 of the present invention, as shown in Figure 3, administrator a purchases or leases a biocoin manufacturing system 3 and uses it to manufacture biocoin. Server A receives biocoin manufacturing-related data via the CPU 11 of the biocoin manufacturing system 3, but unlike the "client-manufactured" system described above, it transfers the manufactured biocoin to client b. The transfer may be for a fee or free of charge.

[0071] Client b, having received biochar from administrator a, applies it to their own farmland, etc. Device B transmits the amount of biochar applied to server A. Server A, having received the amount of biochar applied, then transmits credit exchange application data, created based on this amount of biochar applied and biochar production-related data obtained from biochar production system 3, to device D.

[0072] The CPU 11 may also be Server A, and Server A may directly receive and record biochar production-related data from various measuring instruments 12 during biochar production.

[0073] (1-3) Project registration and credit verification

[0074] (Credit Certification Administrator a) In the biochar credit management system 1 of the present invention, administrator a preferably performs project registration and credit certification as shown in Figure 4 with the certification body d. The details of project registration and credit certification may differ depending on the carbon credit scheme operated by each country, region, or organization, but in this section (1-3) and the following section (1-4), examples of its embodiment will be described mainly with reference to the Japanese carbon credit scheme.

[0075] (Project Registration) Project registration is carried out in the following steps (1) to (5), as shown in the flowchart on the left side of Figure 4. (1) Consideration of participation in the credit scheme. Creation of a project plan. (2) Verification of the validity of the project plan. (3) Application for project registration. (4) Deliberation on project registration (certification committee (certification body d)). (5) Project registration.

[0076] In (1) above, it is preferable to include emission reduction plans and project registration requirements in the project plan based on data such as equipment information for the biochar production system 3 and fuel consumption. In (2) above, the certification body d, etc., will verify the validity of the plan, such as whether there are any errors in the description and whether the equipment is operating properly.

[0077] (Credit Verification) Next, credit verification is carried out according to the steps (1) to (5) described in the flowchart on the right side of Figure 4. (1) Data monitoring and collection. Creation of a monitoring report (2) Verification of the monitoring report (3) Application for credit verification (4) Deliberation on credit verification (Certification Committee (Certification Body d)) (5) Credit verification

[0078] In (1) above, monitoring and collection of necessary data, such as the biochar production-related data mentioned above, will be carried out in accordance with the project plan created in the "Project Registration" above. The emission reduction amount will then be calculated and recorded in the report. Furthermore, in (2) above, it is preferable for the certification body d, etc., to verify whether there are any errors in the report, whether the equipment is operating properly, and the certified amount, etc.

[0079] (1-4) Credit application

[0080] (Biochar material) As mentioned above, biochar in Japan's carbon credit scheme (J-credit scheme), for example, is defined as "a solid substance produced by heating biomass at a temperature exceeding 350°C under an oxygen concentration controlled to a level that does not cause combustion," and its carbon sequestration effect in soil has been recognized. In the biochar credit management system 1 according to the present invention, the biochar material (biomass) is preferably rice husks or buckwheat hulls, and in this embodiment, the biochar material is rice husks, but any organic granular material of a certain size is acceptable and is not particularly limited.

[0081] (Credit Amount) Under the carbon credit scheme, those who apply biochar to agricultural soil can obtain the credits (credit amount) shown in [Equation 1] above. In the biochar credit management system 1 of the present invention, client b is a biochar user, and administrator a applies for credits to certification body d according to the amount applied (credit application), and client b receives a pro-rata share of the sales price of the credits sold by administrator a. [Equation 1], which represents the relationship between biochar application and credit amount, is written again and its contents are explained below.

[0082] [Equation 1] Carbon storage amount (credit amount) = Carbon emission reduction amount = (1) CO2 after project implementation2 Storage amount - (2) CO emissions due to project implementation 2 Emission amount (1) CO emissions after project implementation 2 Storage amount = Biochar application amount (t) × Carbon content rate × Carbon remaining rate after 100 years × 44 / 12 (2) CO emissions due to project implementation 2 Emission amount = CO emissions due to transportation of biochar raw materials and biochar, etc. 2

[0083] (CO 2 Storage amount) In (1) of the above [Equation 1], the "Biochar application amount (t)" is the amount (t) of biochar input into the soil by Client b. Also, the "Carbon content rate" has a default value set by, for example, the "Greenhouse Gas Inventory Report of Japan" in Japan. For example, when the biochar material is "derived from rice husks and rice straw", the default value is "0.49 (pyrolysis)". Also, the "Carbon remaining rate after 100 years" is what remains after subtracting the amount of carbon decomposed and emitted during the 100 years after input, and this also has a default value set by the "Greenhouse Gas Inventory Report of Japan". When the biochar material is "derived from rice husks and rice straw", the default value of the "Carbon remaining rate after 100 years" is "0.65".

[0084] (CO 2 Emission amount) Also, in (2) of the above equation, the "CO emissions due to project implementation" is, as described above, "CO emissions due to transportation of biochar raw materials and biochar, etc.". 2 For this CO emission amount, the following items need to be considered. (i) Emission amount related to transportation of raw materials (ii) Emission amount related to production of biochar (iii) Emission amount related to transportation of biochar (iv) Emission amount related to application of biochar 2 2

[0085] (Credit application) The project administrator a acts on behalf of Client b who joined the project, and for the above "(1) CO storage amount after project implementation" and "(2) CO emissions due to project implementation" 2 2The "emissions" are calculated, and a monitoring report is prepared as described above. Specifically, in accordance with the project plan created in "Project Registration" above, monitoring and collection of the biochar production-related data (firing temperature, biochar material supply amount, biochar production amount, firing time, biochar production site) and other necessary data such as (i) to (iv) above are carried out, the amount of carbon sequestration (amount of carbon emission reduction) is calculated, and recorded in the monitoring report.

[0086] (Credit Application) Once the project registration and credit certification procedures described above are completed (see Figure 4), and the project is started by administrator a, client b may be formally allowed to join the project. Administrator a then applies to certification body d for credits corresponding to client b's biochar application rate. In other words, client b declares the amount of carbon applied to administrator a, and administrator a, acting as the application agent, applies for credits to certification body d and manages the credits certified by certification body d.

[0087] (Credit exchange application data) As described above, administrator a acts as an agent to the certification body d to apply for client b's credits. However, when making this application, it is necessary to support client b's carbon application amount with biochar production-related data. Specifically, server A, which receives the biochar application amount from server B, sends the credit exchange application data, created based on this biochar application amount and the biochar production-related data obtained from the biochar production system 3, to device D of certification body d.

[0088] (Authenticated Credits) Credits authenticated by authentication authority d are sent from device D to administrator a's server A, where administrator a manages them. It is desirable that administrator a notify client b's device B, via server A, of the fact that credits have been acquired and the amount of credits.

[0089] (2) Biochar production system

[0090] (2-1) Configuration of the biochar production system

[0091] As described above, when administrator a applies to certification body d for credit certification, and when client b applies for credits corresponding to the amount of biochar applied, data related to the production of biochar manufactured by client b (amount of biochar material supplied, firing temperature, firing time, amount of biochar produced, biochar production location), data on the amount applied to farmland, and monitoring data such as emissions (i) to (iv) related to the above biochar production are required.

[0092] Collecting such biochar production-related data would be a heavy burden for individual clients b. Therefore, it is desirable that the biochar credit management system 1 according to the present invention be equipped with a system that allows administrator a to automatically collect biochar production-related data when client b produces biochar.

[0093] (Biocin Production System) As such a system, the biocoin credit management system 1 according to the present invention includes a biocoin production system 3, as shown in Figure 7(c) (see Figures 1 to 3). Figure 10 is mainly used in the embodiment of the biocoin credit management system 1 described below, but since it is a detailed view of Figure 7(c), it will also be referred to as appropriate in this Section (2-1).

[0094] This biochar production system 3 is equipped with various measuring instruments 12, including a temperature measuring instrument 121, a biochar supply amount measuring instrument 122, a biochar production amount measuring instrument 123, a clock 124, and a position measuring instrument 125 (see Figures 6(a) and 6(b)). The system consists of a biochar production apparatus 30 (see Figure 11, etc.) having a temperature measuring instrument 121 for measuring the internal temperature of the internal combustion chamber 301 (see Figure 7(c)), an automatic biochar material supply apparatus 35 equipped with a biochar supply amount measuring instrument 122, a biochar storage container 36 equipped with a production amount measuring instrument 123 for measuring the amount of biochar produced, a CPU 11 with a built-in clock 124, and a GPS 125 (see Figures 7(c) and 11, etc.).

[0095] (Biotincture production apparatus) In the biotincture production system 3 with this configuration, the CPU 11 can record the firing temperature, biotincture material supply amount, biotincture production amount, firing time, and biotincture production location measured by the various measuring instruments 12. Furthermore, the biotincture credit management system 1 according to the present invention fixes the components of the biotincture production system 3 to a fixed transport body 50, and the fixed transport body 50 can be moved by a means of transport 500 (see Figures 7(a) and (b)).

[0096] Here, the fixed transport body 50 is a trailer 50A or a container 50B. The means of transport 500 is preferably an automobile, train, ship, airplane, etc.

[0097] (Biotincture Production Equipment) The biotincture production equipment 30, as shown in Figure 7(c), has an internal combustion chamber 301 and a temperature measuring device 121 for measuring its internal temperature (see Figures 9(a) and 11), and produces biotincture by firing biotincture material. The biotincture production system 3, which is sold or leased from company e to client b, is transported on a means of transport 500 as shown in Figures 1 to 3, and installed on the site, such as client b's farmland, along with the fixed transport body 50. The biotincture production equipment 30 can be used on-site while fixed to the fixed transport body 50, but other components of the biotincture production system 3, such as the biotincture material automatic supply device 35 and the biotincture storage container 36, may be unloaded from the means of transport 500 or the fixed transport body 50 and installed on-site.

[0098] (Automatic Biochar Material Supply Device) The automatic biochar material supply device 35 supplies biochar material stored on-site to the biochar production device 30 and is preferably equipped with a supply amount measuring device 122 to measure the amount supplied (see Figures 7(c), 11, etc.). The biochar material supplied to the biochar production device 30 is calcined in its internal combustion chamber 301 and discharged as biochar from the discharge port of the biochar production device 30. The supply amount measuring device 122 measures the mass of the biochar material supplied to the biochar production device 30 and transmits the measured amount (amount of biochar material supplied) to the CPU 11 wirelessly or via wired connection, as shown in Figure 11.

[0099] (Data related to biochar production of the biochar production apparatus) As described above, the biochar production apparatus 30 burns the biochar material supplied by the biochar material automatic supply device 35 in the internal combustion chamber 301 and discharges the biochar from the outlet. The temperature measuring instrument 121 installed in the internal combustion chamber 301 measures the internal temperature (burning temperature) of the internal combustion chamber 301 and transmits it to the CPU 11 wirelessly or via wired connection (see Figure 11).

[0100] (Biochar storage container) The biochar storage container 36 is preferably equipped with a production volume measuring device 123 that stores the biochar discharged from the internal combustion chamber 301 and measures the amount of biochar produced. The production volume measuring device 123 measures the mass of biochar discharged from the biochar production apparatus 30 and transmits the measured amount (biochar production volume) to the CPU 11 wirelessly or via wired connection (see Figure 11).

[0101] (CPU) In the biochar production system 3 according to the present invention, the CPU 11 preferably has a built-in clock 124 and is capable of communication. The CPU 11 preferably records the firing temperature, biochar material supply amount, and biochar production amount received from the temperature measuring instrument 121, supply amount measuring instrument 122, and production amount measuring instrument 123, respectively, along with the time of reception, as shown in Figure 11.

[0102] (GPS) In the biochar production system 3 according to the present invention, the GPS 125 identifies the location of the biochar production system 3 (see Figure 11). It may be installed on the biochar production apparatus 30, but it may also be attached to other components such as the biochar material automatic supply device 35, the biochar storage container 36, or the container 50B.

[0103] In order to produce biochar, in addition to the biochar production apparatus 30 and the automatic biochar material supply apparatus 35, other devices such as a biochar material transfer apparatus, a biochar suction apparatus, and a cyclone separator may also be used. These components of the biochar production system 3 may be loaded onto a fixed transporter 50 together with the fixed biochar production apparatus 30, or they may be provided on-site. In other words, loadable components can be housed in the fixed transporter 50, or loaded onto a means of transport 500 such as a freight car together with the fixed transporter 50, and then towed or transported by the means of transport 500 to a site such as farmland where biochar materials such as rice husks are stored.

[0104] The components of the biochar production system 3, once transported to a farm or other site, can be unloaded from the transportation means 500 along with the fixed transporter 50, or detached from the transportation means 500 and installed at the site along with the fixed transporter 50. Since the components of the biochar production system 3 other than the biochar production apparatus 30 can also be unloaded and installed at the site, biochar can be produced using biochar materials such as rice husks stored at that site.

[0105] (2-2) Embodiment of a biochar production system

[0106] The embodiments of the biochar production system 3 described in Section (2-1) above will be explained below using a rotary kiln-type mobile biochar production apparatus 31 as an example. However, the biochar production apparatus 30 does not need to be mobile as described below, and may be a stationary biochar production apparatus installed indoors or elsewhere.

[0107] Furthermore, the biochar material (charcoal material) used by this charcoal production apparatus 31 is rice husk material (hereinafter also simply referred to as "rice husk"), but as mentioned above, the biochar material is not limited to rice husk material. The biochar material may be, for example, buckwheat hulls, peanut shells, corn cobs, rice straw, wood chips, or other agricultural processing residues in addition to rice husks. Biochar is a solid carbon material with high carbon stability produced by a pyrolysis process using these biochar materials as raw materials, and may be fixed in the soil for a long period of time as a soil conditioner or fertilizer carrier.

[0108] Furthermore, the biochar production apparatus 30 is not limited to the charcoal production apparatus 31 described in the following example, but is not particularly limited to any apparatus capable of producing the above-mentioned biochar as a result using the above-mentioned biochar material as a raw material. Therefore, the biochar production apparatus 30 does not necessarily have to be a production apparatus that exclusively produces biochar such as charcoal, and may be a production apparatus that produces biochar as a by-product, such as a house heater that generates heat using biochar material as fuel.

[0109] (Rotating kiln type mobile charcoal production apparatus, component 1, component 2) As shown in Figures 8 to 10, the mobile charcoal production apparatus 31 according to this embodiment includes: (Component 1) a rotating kiln 310 that burns rice husks 2 fed in from the connection part 310c side in an internal combustion chamber 301 and discharges the calcined charcoal 3 from the discharge part 310d; (Component 2) an external combustion chamber 320 connected to the connection part 310c of the rotating kiln 310. The charcoal production apparatus 31 can be fixed to the floor of a fixed transport body 50 using fixing means and transported by transport means 500 (see Figures 7(a) to (c), Figures 1 to 3, etc.).

[0110] (Rotating Kiln Installation Stand) The fixed transport body 50 fixes the external combustion chamber 320 of the charcoal production apparatus 31 to its floor and also fixes the rotating kiln installation stand 316 for installing the rotating kiln 310. As shown in Figure 8, the rotating kiln installation stand 316 allows the rotating kiln 310 to be installed such that the connection part 310c of the rotating kiln 310 is connected to the external combustion chamber 320 and the rotating kiln 310 is tilted at a predetermined angle relative to the floor 11 from the connection part 310c toward the discharge part 310d.

[0111] (Fixed Transport Unit) The fixed transport unit 50 can be transported by fixing the charcoal production apparatus 31, which includes at least a rotary kiln 310 fixed to a rotary kiln mounting base 316 and an external combustion chamber 320, to the fixed transport unit 50, and then loading, storing, or connecting the fixed transport unit 50 to the transport means 500. Furthermore, as described above, the fixed transport unit 50 can be loaded and unloaded from the transport means 500.

[0112] (Configuration of the charcoal production apparatus) The charcoal production apparatus 31 according to this embodiment includes the rotary kiln 310 (component 1) and the external combustion chamber 320 (component 2), as well as the following components (component 3) to (component 6) (see Figures 8 to 11). (component 3) Air supply means 330 for supplying air into the rotary kiln 310 (see Figure 10) (component 4) Charcoal material input pipe 315 for introducing rice husks r into the rotary kiln 310 (component 5) One or more rotating support members 314 that rotatably support the rotary kiln 310 and can be fixed to the floor of the fixed transport body (see Figure 9) (component 6) Rotary drive device 340 for rotating the rotary kiln 310 (see Figure 11)

[0113] (Component 5: Rotating support) The charcoal production apparatus 31, which comprises the above-mentioned (Component 1) to (Component 6), fixes the rotating kiln 310 at a predetermined angle inclined with respect to the floor 11 of the fixed transport body 50, from the connection part 310c side into which the rice husks r are fed toward the discharge part 310d. The rotating support 314 (Component 5) that rotatably supports the rotating kiln 310 is, for example, one or more rollers 314 (see Figure 9(a)), and can be provided on a rotating kiln mounting base 316 fixed to the floor of the fixed transport body 50.

[0114] (Partition plates, stirring plates and internal combustion chamber) The inner circumferential surface of the rotating kiln 310 is provided with one or more axial partition plates 312a, 312b (see Figure 9(a)) that partition the introduced rice husks r in the direction of its central axis 311c, and one or more stirring plates 311p that stir the rice husks r in the direction of its rotation (see Figure 9(b)). The internal combustion chamber 301 (301a, 301b) is formed by being demarcated by these axial partition plates 312a, 312b, as shown in Figure 9(a).

[0115] (Component 3: Air supply means) As shown in Figures 10 and 9(a), the charcoal production apparatus 31 of this embodiment is equipped with an air supply means 330 (component 3) for introducing air into the rotary kiln 310. This air supply means 330 includes, for example, an air supply pipe 332 with many air holes inserted into the rotary kiln 310 and an air blower 334 connected thereto, which sends air into the internal combustion chambers 301a and 301b of the rotary kiln 310 via the air supply pipe 332 and the air blower 334.

[0116] (Exhaust means) It is also preferable to provide a chimney 322 as an exhaust means 322 in the external combustion chamber 320 connected to the connection part 310c side of the rotary kiln 310, as shown in Figure 8 or Figure 9(a). When the internal combustion chamber 301 of the charcoal production apparatus 31 reaches a certain high temperature due to the combustion of rice husks r, a flow of air is generated from the chimney 322 provided in the external combustion chamber 320, drawing air in from inside the rotary kiln 310, reducing the pressure inside the rotary kiln 310, and drawing in outside air from the discharge part 310d side. As a result, a flow of air is created from the discharge part 310d side of the rotary kiln 310, passing through the inside of the rotary kiln 310 and being exhausted from the chimney 322 of the external combustion chamber 320, and this air can cool the charcoal c that has been burned.

[0117] (Component 4: Charcoal Material Input Pipe) As shown in Figures 10 and 9(a), one end of the charcoal material input pipe 315 of component 4 is inserted into the internal combustion chamber 301 of the rotary kiln 310, and the other end is connected to the automatic charcoal material supply machine (automatic biochar material supply device) 35. The charcoal material input pipe 315 blows the charcoal material r accumulated in the automatic charcoal material supply device 35 with an air blower 354 and supplies it to the internal combustion chamber 301 via the rice husk transfer pipe 355 (see Figure 10).

[0118] (Component 6: Rotary Drive Device) The rotary drive device 340 also includes, as shown in Figure 11, an inverter 341 capable of modulating the voltage from the power supply ES, a motor 342 connected to the inverter 341, and an interlocking means 343 that interlocks the motor 342 and the rotary kiln 310, and the rotary kiln 310 rotates in the circumferential direction in conjunction with the rotation of the motor 342 via the interlocking means 343.

[0119] Here, the interlocking means 343 may consist of a chain fixed in the circumferential direction of the rotating kiln 310 and a sprocket connected to the motor 342 and meshing with the chain. Alternatively, it may consist of a ring gear fixed in the circumferential direction of the rotating kiln 310 and a smooth wheel connected to the motor 342 and meshing with the ring gear, and its configuration is not particularly limited.

[0120] Such a rotary drive device 340 can adjust the rotation speed of the rotary kiln 310, which is linked to the rotation of the motor 342, via the interlocking means 343 by adjusting the rotation speed of the motor 342 with the inverter 341.

[0121] (3) Embodiment of managing biochar production-related data

[0122] As described above, the biochar production system 3 according to the present invention includes various measuring instruments 12 that measure biochar production-related data, including at least the firing temperature, the amount of biochar material supplied, the amount of biochar produced, the firing time, and the biochar production location, and a CPU 11 that can communicate with the various measuring instruments 12 (see Figures 6(a) and 6(b)). Server A can acquire biochar production-related data during biochar production from these various measuring instruments 12 via the CPU 11. As described above, the CPU 11 may be the same as Server A or Device B, and the biochar production system 3 may be configured so that Server A or Device B directly acquires biochar production-related data from the various measuring instruments 12 (see Figure 3 or Figure 2).

[0123] The various measuring instruments 12 described above (temperature measuring instrument 121, supply amount measuring instrument 122, production amount measuring instrument 123, clock 124, GPS 125, etc.) are preferably kept permanently on the mobile charcoal production apparatus 31, but may also be added to the charcoal production system (biotincture production system) 3 at the destination of transport. Furthermore, among the various measuring instruments 12, small devices such as the GPS 125 and clock 124 can be housed together with the CPU 11 in the control panel 10 (see Figure 8).

[0124] In this section (3), we will continue to use the mobile charcoal production device 31 as the biochar production device 30 to explain the management of biochar production-related data in the biochar production system 3.

[0125] (3-1) Measurement of biochar production-related data

[0126] (3-1a) Measurement of charcoal production volume, firing time, and charcoal production location

[0127] (Amount of charcoal produced, firing time, charcoal production location) As shown in Figure 11, the biochar production system 3 of the present invention includes a GPS 125, so the location of the mobile charcoal production device 31 can be confirmed, and therefore the charcoal production location can be measured. In addition, a clock 124 is usually provided with the GPS 125, so the biochar production system 3 can measure the firing time of the charcoal production device 31 (mobile charcoal production device 31). Furthermore, the biochar production system 3 can measure the amount of charcoal produced by, for example, equipping the charcoal intake container (flexible container) 368 shown in Figure 10 with a weighing scale (production amount measuring device) 123.

[0128] (3-1b) Measurement of the amount of charcoal material supplied

[0129] (Amount of charcoal material supplied) In addition, in the biochar production system 3 according to the present invention, the amount of charcoal material supplied is measured, for example, using the automatic charcoal material supply device 35 as in the following example 7.

[0130] (Configuration of the automatic charcoal material supply machine) As shown in Figure 11, the automatic charcoal material supply device 35 includes an inverter 351 capable of modulating the voltage from the power supply ES, a motor 352 connected to the power supply ES via the inverter 351, a screw 353 connected to the motor 352 for transporting the charcoal material, and an air blower 354 that supplies the charcoal material r transported by the screw 353 to the internal combustion chamber 301 of the charcoal production device 31 via a rice husk transport pipe 355 (and charcoal material input pipe 315) (see Figures 9 and 10).

[0131] As shown in Figures 10 and 11, the automatic charcoal material supply device 35 transports the charcoal material r that descends from the hopper (charcoal material input container) 374 toward the air blower 354 using a screw 353. By adjusting the rotational speed of the motor 352 with the inverter 351, the amount of charcoal material r transported by the screw 353 connected to the motor 352 can be adjusted (see Figure 11).

[0132] (Supply amount measuring device) Therefore, the supply amount measuring device 122 can calculate the amount of charcoal material r transported per unit of time by the rotational speed of the screw 353 (motor 352) adjusted by the inverter 351, and determine the amount of charcoal material supplied.

[0133] (3-1c) Measurement of firing temperature

[0134] (Firing Temperature) In the kiln-type charcoal production apparatus 31, the firing temperature can be measured using, for example, a thermocouple 121. That is, in the biochar production system 3 according to the present invention, the temperature measuring instrument 121 can measure the temperature inside the internal combustion chamber 301 by attaching the thermocouple 121 to the tip of the charcoal material input pipe 315 inserted into the internal combustion chamber 301 of the kiln-type charcoal production apparatus 31, as shown in Figure 11.

[0135] (3-2) Blockchain

[0136] The biochar production-related data (firing temperature, biochar material supply amount, biochar production amount, firing time, biochar production location, etc.) obtained from the various measuring instruments 12 of the biochar production system 3, as described above, can be recorded on a public blockchain to prevent tampering and other fraudulent activities.

[0137] Specifically, referring to Figure 12, in the biochar credit management system 1 according to the present invention, the management server A receives signed data with the hash value of biochar production-related data as message z via the CPU 11 of the biochar production system 3, and verifies the authenticity of the received signed data. If authenticity is confirmed, message z can be recorded on the public blockchain 710. As described above, the CPU 11 of the biochar production system 3 may be the same as device B, in which case device B obtains biochar production-related data directly from various measuring instruments 12.

[0138] The following describes how to record biochar production-related data on a public blockchain 710, using a client-manufactured biochar credit management system 1 as an example, as shown in Figure 5.

[0139] (Biocin Credit Management System) Figure 12 shows a part of a client-manufacturing type biocoin credit management system 1 in which device B of client b collects biocoin production-related data from biocoin production system 3. In this embodiment, the CPU 11 of biocoin production system 3 is set to CPU B1 of device B, and device B directly acquires biocoin production-related data via various measuring instruments 12.

[0140] The biochar credit management system 1 according to this embodiment, as shown in Figure 12, has a database and is connected to a management server A that manages a mobile charcoal production apparatus 31 and related biochar production data, a device B which has a CPU B1, a transceiver B3, and a memory B4 and can receive biochar production related data measured by various measuring instruments 12 of the mobile charcoal production apparatus 31 via the transceiver B3 and store it in the memory B4, and a device C which can be registered with and accessed by the management server A, via a communication network 700. The communication network 700 may be the Internet 700.

[0141] (Biotincture Credit Management System) The biotincture credit management system 1 allows device B of a mobile charcoal production device 31, whose MAC address is registered with management server A, to transmit biotincture production-related data received from various measuring instruments 12 of the mobile charcoal production device 31 to management server A via its transceiver B3. Management server A can then store the biotincture production-related data received from device B in its database. Furthermore, device C, which is registered with management server A, can access management server A and view the biotincture production-related data stored in its database if certain conditions are met.

[0142] (Blockchain) As described above, the biochar credit management system 1 can store biochar production-related data received from device B in the database of management server A. Furthermore, the biochar credit management system 1 according to the present invention can guarantee the authenticity of the biochar production-related data by recording the hash value of this biochar production-related data on the public blockchain 710. The configuration of the biochar credit management system 1 of this embodiment that utilizes the public blockchain 710 and the method of recording biochar production-related data on the public blockchain 710 will be described below with reference to Figure 12.

[0143] (Private Key, Public Key, and ID Address) In this embodiment, the biochar credit management system 1 has a device B of the mobile charcoal production apparatus 31 equipped with a secure element B2, which can generate a random private key and store it in the secure element B2. Device B generates a public key from the private key using a predetermined program and hashes it using a predetermined hash function. Then, it generates an ID address from this hashed public key according to a predetermined rule and records and registers it in the database of the management server A along with the MAC address of device B.

[0144] Here, the predetermined program is, for example, secp256k1, and the predetermined hash function is, for example, Keccak256. The predetermined rule for generating the ID address is, for example, an Ethereum-style rule that prefixes the last 20 bytes of the hash value of the public key with 0x.

[0145] (Message z, signature) Next, device B hashs the biochar production-related data received from the various measuring instruments 12 of the mobile charcoal production apparatus 31 and stored in its memory B4 to generate message z. Then, using the public key generated from the private key, it generates a signature for message z in a predetermined signature format and sends the signature data consisting of this signature and the generated message z to the management server A. The predetermined signature format is, for example, the Ethereum signature format.

[0146] (Verification of signature data) In this manner, the management server A, which has received signature data from device B of the mobile charcoal production device 31, recovers the public key from the received signature data in the predetermined signature format and hashes it using the predetermined hash function. Then, it can generate a verification ID address from this hashed public key according to the predetermined rules.

[0147] Management server A compares this verification ID address with the ID address of device B, which is recorded and registered in its database along with its MAC address, to check if they match. If they match, it can be confirmed that the signature data received from device B of the mobile charcoal production device 31 was generated using the same public key that generated the previously registered ID address.

[0148] (Public Blockchain) As described above, in the biochar credit management system 1 according to this embodiment, the management server A compares the verification ID address received from device B of the mobile charcoal production device 31 with the ID address of device B. If the two match, the management server A records the signature data message z received from device B on the public blockchain 710 to prevent tampering.
