The electric power used in the electric furnace EF of the present embodiment is electric power that does not emit carbon dioxide and is generated from a non-fossil power source such as renewable energy. Renewable energy here refers to the following energy sources.
(1) Solar power (2) Wind power (3) Hydro power (4) Geothermal power (5) Biomass (organic matter derived from animals and plants that can be used as an energy source (excluding crude oil, petroleum gas, combustible natural gas, coal, and products manufactured from these. ).)
(6) In addition to the energy sources listed in 1 to 5 above, among energy sources other than crude oil, petroleum gas, combustible natural gas, coal, and products manufactured from these, those that can be used permanently as an energy source for electricity. Those specified by Cabinet Order as permitted

Non-fossil power sources include, for example, nuclear power as well as renewable energy. Electricity generated from non-fossil power sources includes the following two.
1. Value of electricity itself (kWh value, etc.)
2. Non-Fossil Value In the present embodiment, the "non-fossil value" of the above two values is referred to as non-fossil value. The electric furnace EF uses electric power defined as a non-fossil value. The non-fossil value here is the value recorded as a non-fossil power source when calculating the non-fossil power source ratio in Japan's "Energy Supply Structure Advancement Act". Non-fossil value is the value purchased by new electricity retailers to meet the stated target value.

Power, defined by non-fossil values, is obtainable and verifiable, for example, using at least one of the following three means.
(1) Non-fossil certificate (2) Green power certificate (3) J credit

A non-fossil certificate is a certificate that expresses the environmental value of electricity generated by renewable energy.

A green power certificate is a certificate of the environmental value of power generated by renewable energy. A serial number is attached to the Green Power Certificate, making it unique. The green power certificate includes information on the amount of power generated, the period of power generation, the method of power generation, and the date of issuance of the certificate. The green power certificate further includes information on the name of the certification body and the name of the certificate issuer.

J-credit is a system in which the government certifies the emission reduction amount and absorption amount of greenhouse gases such as carbon dioxide as "credits".

Additionally or alternatively, power defined in non-fossil value may also be obtained and verifiable by the following means.
(4) Power generation using solar power generation equipment owned by the company

As an alternative, the power used in the electric furnace EF may be power defined as a zero-emission value rather than power defined as a non-fossil value. The zero-emission value here is the value for which the carbon dioxide emission coefficient in Japan's "Law Concerning Promotion of Global Warming Countermeasures" (hereinafter referred to as the Global Warming Law) is zero. Specifically, the zero-emission value is calculated by multiplying the amount of electricity from the non-fossil fuel certificates procured by the electricity retailer when calculating the post-adjustment emission factor by the "national average factor". A value that can be subtracted from emissions. When power purchasers such as manufacturers report their carbon dioxide emissions to the government based on the Global Warming Law, the carbon dioxide emission factor for power with zero emission value is zero. For example, electricity defined as zero-emission value may be electricity generated by an existing electricity sales company using renewable energy, such as hydropower, or nuclear power. Power, defined as a zero-emission value, is obtainable and verifiable by the following means.
(5) Contracts with electricity retailers (e.g. “Aqua Premium” (registered trademark) and “Aqua Energy 100” provided by TEPCO Energy Partner (registered trademark))

For each of the means (1) to (5) exemplified above, information such as a certificate certifying that the electric power used in the electric furnace EF is defined as non-fossil value or zero emission value is unique It is obtained from a certificate issuing business or a certification authority as unique certification information. The above means (1) to (5) are examples, and can be replaced by any other means that proves that the electric power used in the electric furnace EF is electric power defined by non-fossil value or zero emission value. be.

In the present invention, the method of certifying that the electric power used in the electric furnace EF is electric power defined by non-fossil value or zero emission value is obtained by obtaining the certification information by any of the above (1) to (5). Alternatively, if the certification information cannot be obtained, a method of specifying only renewable energy-derived power using arbitrary certification information (e.g., carbon dioxide emission coefficient (residue)) published by electric power companies, etc. (details will be described later).

The information processing device 1 can communicate with one or more other information processing devices 2 to 5 via the network NW. Although five information processing apparatuses 1 to 5 are connected to the network NW in FIG. 3, the number of information processing apparatuses is arbitrary. Since the hardware configurations of the information processing apparatuses 2 to 5 are the same as the hardware configuration of the information processing apparatus 1, description thereof will be omitted here.

The information processing device 1 is a computer such as a server belonging to a cloud computing system or other computing system. Alternatively, the information processing device 1 may be a mobile device such as a mobile phone, smart phone, wearable device, or tablet. As another alternative, information processing device 1 may be a general-purpose device such as a PC, or a dedicated device. "PC" is an abbreviation for personal computer.

The internal configuration of the information processing apparatus 1 will be described in detail with reference to FIG.

Information processing device 1 includes control unit 11 , communication unit 12 , and storage unit 13 . Each component of the information processing apparatus 1 is communicably connected to each other via a dedicated line, for example.

The control unit 11 includes, for example, one or more general-purpose processors including a CPU (Central Processing Unit) or MPU (Micro Processing Unit). Control unit 11 may include one or more dedicated processors specialized for specific processing. Control unit 11 may include one or more dedicated circuits instead of including a processor. The dedicated circuit may be, for example, an FPGA (Field-Programmable Gate Array) or an ASIC (Application Specific Integrated Circuit). The control unit 11 may include an ECU (Electronic Control Unit). The control unit 11 transmits and receives arbitrary information via the communication unit 12 .

The communication unit 12 includes a communication module compatible with one or more wired or wireless LAN (Local Area Network) standards for connecting to the network NW. The communication unit 12 may include modules compatible with one or more mobile communication standards including LTE (Long Term Evolution), 4G (4th Generation), or 5G (5th Generation). The communication unit 12 supports one or more short-range communication standards or specifications including Bluetooth (registered trademark), AirDrop (registered trademark), IrDA, ZigBee (registered trademark), Felica (registered trademark), or RFID. It may include modules and the like. The communication unit 12 transmits and receives arbitrary information via the network NW.

A semiconductor memory is, for example, a RAM or a ROM. RAM is, for example, SRAM or DRAM. ROM is, for example, EEPROM. The storage unit 13 may function, for example, as a main storage device, an auxiliary storage device, or a cache memory. The storage unit 13 may store information of results analyzed or processed by the control unit 11 . The storage unit 13 may store various kinds of information regarding the operation or control of the information processing device 1 . The storage unit 13 may store system programs, application programs, embedded software, and the like. The storage unit 13 may be provided outside the information processing device 1 and accessed from the information processing device 1 . The storage unit 13 includes a manifest DB.

The network NW is, for example, a distributed ledger (Hyperledger) type blockchain network. In this case, all nodes connected to the network NW hold the same data as one or more blocks in chronological order.

The network NW may be a public network connected to the Internet, or may be a private network.

The storage unit 13 of the information processing device 1 stores the block chain BC as shown in FIG. The blockchain BC is shared by all nodes in the blockchain network NW. Here, for convenience of explanation, a case where the block chain BC includes a first block B1, a second block B2, a third block B3 and a fourth block B4 is explained. The number of blocks included in the blockchain BC is arbitrary.

The first block B1 is the first block of the blockchain BC and contains transaction data T1. In FIG. 5, one block contains three pieces of transaction data. However, the number of transaction data contained in one block is arbitrary.

The second block B2 contains the hash H2 of the previous block, the first block B1, the nonce value N2 corresponding to the hash H2, and the transaction data T2.

For each manifest, the control unit 11 of the information processing device 1 certifies that the manifest information and the electric power used in the electric furnace EF during waste treatment is defined as non-fossil value or zero emission value. Integrate with credentials. Here, the certification information can be obtained by the following method. In order to realize that the electric power used in the electric furnace EF is electric power defined by non-fossil value or zero emission value, first, in the electric furnace EF in which the waste described in the target manifest M is processed The amount of electricity used per ton of waste is calculated from the actual electricity consumption of the factory. The calculation may be performed by the control unit 11 (for example, a process computer) or may be performed manually (the same shall apply hereinafter). Next, by multiplying the amount of power consumption per ton of waste by the amount of waste described in the manifest M, the actual power consumption used to process the target waste is calculated. be. By regarding the power of this actual power consumption as non-fossil power, it is possible to realize and prove that the power used in the electric furnace EF is the power defined by non-fossil value or zero emission value.

As a specific example of the method of integrating the manifest information and the certification information, the control unit 11 associates the manifest information M1 and the certification information V1 with the block B1 of the blockchain BC as shown in the manifest DB of FIG. Stored in the storage unit 13 . That is, the manifest information M1 and the proof information V1 are registered as transaction data in the block B1 of the blockchain BC. The registered information is stored as tokens of the blockchain BC. Alternatively, the certification information V1 may be embedded in the manifest information M1.

The control unit 11 can disclose the manifest information M1 and the certification information V1 to arbitrary third parties on the Internet or the like.

An information processing method by the control unit 11 of the information processing device 1 will be described with reference to FIG.

In step S1, the control unit 11 receives manifest information about waste treatment and proof information proving that the power used for waste treatment is defined as non-fossil value or zero emission value. get.

In step S2, the control unit 11 integrates the manifest information and the certification information by associating them.

In step S3, the control unit 11 registers the associated manifest information and certification information in the network NW (eg, blockchain network NW). Step S3 is optional.

In step S4, the control unit 11 publishes the associated manifest information and certification information on the Internet. Step S4 is optional.

[Modification]
In the above embodiment, the manifest information and the certification information are stored in the storage unit 13 in association with each other. However, there are cases where the control unit 11 cannot obtain certification information such as a green power certificate. Therefore, if the power generation process of the power purchased by the power consumer is a process that uses renewable energy and energy other than renewable energy in combination, the control unit 11 controls the regeneration of purchased and used power. Can only be specified for electricity from renewable energy sources. Such identification can be performed using any certification information (eg, carbon dioxide emission factor (residue)) published by the power company or the like. The control unit 11 may store the certification information in association with the manifest information.

As described above, if the power generation process of the power purchased by the power consumer is a process that uses a combination of renewable energy and non-renewable energy, renewable energy out of the power purchased and used Only the derived power can be specified. The reason why it is possible to specify is as follows at the 15th Ministry of Economy, Trade and Industry Advisory Committee on Natural Resources and Energy, Electricity and Gas Business Subcommittee, Electricity and Gas Basic Policy Subcommittee System Review Working Group (November 28, 2017). This is because In other words, as a result of the auction of non-fossil certificates subject to FIT (Feed-in Tariff), if it is assumed that there will be non-fossil certificates that remain unsold without being contracted, the non-fossil certificates will be It cannot be carried over to the next fiscal year, and will be treated as "surplus non-fossil electricity equivalent". Regarding the zero-emission value among the environmental values related to surplus non-fossil electricity equivalents, in consideration of the fact that consumers bear the cost as FIT surcharge, etc., the value will not be buried, and it will be calculated according to the share of the amount of electricity sold. It was decided to distribute.

In addition, the CO2 emission factors of electric power companies for the current fiscal year may be published after the end of the fiscal year. In this case, the carbon dioxide emission factor for this year can be calculated by the control unit 11 according to the following procedure.
Procedure 1. Based on the carbon dioxide emission coefficient and non-fossil power ratio of the previous year, we estimate the amount of non-fossil power that can be used on the basis of the previous year, and reflect the estimation results in the planned power plan to be used at the factory this year. As an alternative example, the non-fossil power ratio may adopt the renewable energy ratio target value for the current year described in the energy environment plan published by any local government.
Procedure 2. Depending on the customer's request, non-fossil power for this fiscal year will be appropriated.
Step 3. When the carbon dioxide emission factor for this fiscal year is released, we will adjust and finalize the performance of the allocation of non-fossil electricity and the remaining electricity other than non-fossil electricity.

If the power generation process is a process that uses renewable energy and non-renewable energy in combination, the following method is used to identify only renewable energy-derived power among the purchased and used power. can be obtained by In order to realize that the electric power used in the electric furnace EF is electric power defined as non-fossil value or zero emission value, first, the factory power consumption equivalent to one heat of the target electric furnace EF is operated Calculated from actual results. The calculation may be performed by the control unit 11 (for example, a process computer) or may be performed manually (the same shall apply hereinafter). One heat is molten steel that is melted once in the electric furnace EF. Next, by multiplying the amount of power used for one heat by the renewable energy ratio disclosed by the electric power company or the like, the amount of power derived from renewable energy is calculated. Then, the power consumption per ton of waste is calculated from the actual power consumption in the electric furnace EF in which the waste described in the target manifest M is processed. Next, by multiplying the amount of power consumption per ton of waste by the amount of waste described in the manifest M, the actual power consumption used to process the target waste is calculated. be. By regarding the power of this actual power consumption as renewable energy power, it is possible to realize and prove that the power used in the electric furnace EF is the power defined as non-fossil value or zero emission value.

[effect]
As described above, according to the present embodiment, waste is processed in an electric furnace that uses electricity defined as non-fossil value or zero emission value. Here, most of the energy (for example, 80% or more) used in the electric furnace is electric power. Under these circumstances, it is possible to offset the carbon dioxide emitted from coke, etc. used in the process by procuring electricity defined by non-fossil value or zero emission value (e.g., green electricity) and using it in electric furnaces. can. In other words, offsetting means calculating the non-fossil power consumption equivalent to energy such as coke, adding the calculated non-fossil power consumption to the manifest, and This is done by associating with the waste as Thus, the feasibility of carbon-neutral waste disposal can be easily enhanced. Furthermore, almost 100% recycling is possible because the residue in the electric furnace after the waste is melted is almost zero. For this reason, the life of the landfill site is extended.

In contrast, the energy used to treat waste in incinerators is diverse, including city gas, natural gas, heavy oil, and kerosene. In this case, the proof of carbon neutrality requires complicated calculations based on the LCA evaluation, and it is impossible to achieve carbon neutrality even with calculations.

Further, according to the present embodiment, the recycling method is a method of processing waste in an electric furnace using electric power defined by non-fossil value or zero emission value, and recycling the processed waste as a recycling raw material. Nearly 100% recycling is possible because the residue in the electric furnace after the waste is melted is almost zero. For this reason, the life of the landfill site is extended.

Further, according to the present embodiment, the information processing apparatus 1 includes manifest information about waste and a certificate certifying that the power used for processing the waste is defined as non-fossil value or zero emission value. Associate with information. This configuration makes it easy to prove that the waste treatment is carbon neutral.

Also according to this embodiment, the network NW comprises a blockchain network, and the associated manifest information and proof information are registered in the blockchain. When blockchain technology is used in this way, registration information is distributed and shared by all nodes. That is, no central administrator is required. Therefore, the following effects are obtained.
・Difficult to tamper ・Since there is no single point of failure, there is no system down ・Easy to share data with other system . Furthermore, since all data is recorded in the blockchain, traceability is ensured.

Further, according to the present embodiment, the control unit 11 publishes the associated manifest information and certification information on the Internet. With this configuration, the information processing apparatus 1 can show to the outside that the waste treatment is carbon neutral.

Further, according to the present embodiment, if the power generation process of the purchased power is a process that uses renewable energy and energy other than renewable energy in combination, the control unit 11 controls the power generated from the renewable energy. and correlating certification information that certifies that the identified power is renewable energy-derived power with manifest information about the waste to be processed in the electric furnace. With this configuration, the information processing device 1 can prove that the waste treatment is partially carbon-neutral, even if non-renewable energy is used in the power generation process.

Although the present disclosure is described with reference to figures and examples, it should be noted that various variations and modifications may be made by those skilled in the art based on the present disclosure. Other modifications are possible without departing from the scope of the present disclosure. For example, functions included in each means or each step can be rearranged so as not to be logically inconsistent, and a plurality of means or steps can be combined into one or divided.

For example, in the above embodiment, a program for executing all or part of the functions or processes of the information processing device 1 can be recorded in a computer-readable recording medium. Computer-readable recording media include non-transitory computer-readable media, such as magnetic recording devices, optical discs, magneto-optical recording media, or semiconductor memories. Program distribution is performed by selling, assigning, or lending a portable recording medium such as a DVD (Digital Versatile Disc) or a CD-ROM (Compact Disc Read Only Memory) on which the program is recorded. Also, the distribution of the program may be performed by storing the program in the storage of an arbitrary server and transmitting the program from the arbitrary server to another computer. A program may also be provided as a program product. The present disclosure can also be implemented as a program executable by a processor.

A computer temporarily stores, for example, a program recorded on a portable recording medium or a program transferred from a server in a main storage device. Then, the computer reads the program stored in the main storage device with the processor, and executes processing according to the read program with the processor. The computer may read the program directly from the portable recording medium and execute processing according to the program. The computer may execute processing according to the received program every time the program is transferred from the server to the computer. The processing may be executed by a so-called ASP type service that realizes the function only by executing the execution instruction and obtaining the result without transferring the program from the server to the computer. "ASP" is an abbreviation for application service provider. The program includes information that is used for processing by a computer and that conforms to the program. For example, data that is not a direct instruction to a computer but that has the property of prescribing the processing of the computer corresponds to "things equivalent to a program."
