The table below classifies the above-mentioned waste materials for recycling from the viewpoint of the type of waste.

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 means the following energy sources.
(1) Solar (2) Wind power (3) Hydropower (4) Geothermal (5) Biomass (organic substances derived from animals and plants that can be used as an energy source (crude oil, petroleum gas, combustible natural gas and coal, and products manufactured from them are excluded). ).)
(Vi) In addition to the energy sources 1 to 5 above, of the energy sources other than crude oil, petroleum gas, combustible natural gas and coal, and products manufactured from these, they can be permanently used as an energy source for electricity. Those specified by government ordinance as permitted

Non-fossil power sources include not only renewable energy, but also nuclear power, for example. The electricity generated from non-fossil power sources includes the following two.
1. 1. Value of electricity itself (kWh value, etc.)
2. 2. Value as a non-fossil In this embodiment, the "value as a non-fossil" out of the above two values is referred to as a non-fossil value. In the electric furnace EF, the power defined by the non-fossil value is used. The non-fossil value here is the value recorded as a non-fossil power source when calculating the non-fossil power source ratio under the "Energy Supply Structure Advancement Law" of Japan. Non-fossil value is the value purchased by a new electricity retailer to achieve a set target.

Power defined by non-fossil value can be obtained and proved using, for example, 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 of the environmental value of electricity generated by renewable energy.

A green power certificate is a certificate of the environmental value of electricity generated by renewable energy. The green power certificate is unique because it has a serial number. The green power certificate contains information on the amount of power generated, the period of power generation, the method of power generation, and the issue date of the certificate. The green power certificate also contains information on the name of the certification body and the name of the certificate issuer.

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

As an additional or alternative example, power defined by non-fossil value can also be obtained and proved by the following means:
(4) Power generation using the solar power generation equipment owned by the company

As an alternative, the power used in the electric furnace EF may be power defined by zero emi value rather than power defined by non-fossil value. The zero-emi value here is the value at which the carbon dioxide emission factor under the "Act on Promotion of Global Warming Countermeasures" (hereinafter referred to as the "warm-to-war method") in Japan is zero. Specifically, the zero emi value is the actual carbon dioxide emissions calculated by multiplying the amount of electricity of the non-fossil certificate procured by the electricity retailer by the "national average coefficient" when calculating the adjusted emission factor. It is a value that can be subtracted from emissions. When a power purchaser in the manufacturing industry reports carbon dioxide emissions to the government based on the warm-air method, the carbon dioxide emission factor of power with zero emi value becomes zero. For example, the electric power defined by the zero emi value may be electric power generated by an existing electric power sales company using renewable energy such as hydropower or nuclear power. Power defined with zero emi value can be obtained and proved by the following means:
(5) Contract with an electric power retailer (eg, "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, there is only information such as a certificate certifying that the electric power used in the electric furnace EF is the electric power defined by the non-fossil value or the zero emi value. Obtained from a certificate issuer or certification body as unique certification information. The above means (1) to (5) are examples and can be replaced by any other means to prove that the power used in the electric furnace EF is the power defined by the non-fossil value or the zero emi value. be.

In the present invention, as a method for certifying that the electric power used in the electric furnace EF is the electric power defined by the non-fossil value or the zero energy value, the proof information is obtained by any of the above (1) to (5). Or if the certification information is not available, use any certification information published by the electric power company (for example, carbon dioxide emission factor (residue)) to specify only the power derived from renewable energy. (Details will be described later).

The waste to be treated is controlled by the manifest M illustrated in FIG. Manifest M is a slip required when consigning the treatment of industrial waste, and is also called an industrial waste management slip. Manifest M may be either D-vote or E-vote.

The waste is associated with the manifest M. As shown in FIG. 2, the manifest M includes, for example, the following manifest information 21 to 25 and the proof information 26, and the manifest information and the proof information are associated with each other.

For example, the manifest information 21 to 25 included in the manifest M and the proof information 26 certifying that the power used in the electric furnace EF is the power defined by the non-fossil value or the zero emi value are the electric furnace EF. It is electronically acquired by the information processing device 1 operated by an administrator or the like and stored in the storage unit 13 of the information processing device 1. As an alternative example, the manifest information and the certification information may be manually input by the user and stored in the storage unit 13 of the information processing apparatus 1.

As shown in FIG. 3, the information processing apparatus 1 is one of the nodes communicably connected to the network NW. The information processing device 1 can communicate with each other with one or more other information processing devices 2 to 5 via the network NW. In FIG. 3, five information processing devices 1 to 5 are connected to the network NW, but the number of information processing devices is arbitrary. Since the hardware configuration of the information processing devices 2 to 5 is the same as the hardware configuration of the information processing device 1, the description thereof is omitted here.

The information processing device 1 is a computer such as a server belonging to a cloud computing system or another computing system. As an alternative example, the information processing device 1 may be a mobile device such as a mobile phone, a smartphone, a wearable device, or a tablet. As another alternative example, the 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.

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

The control unit 11 includes, for example, one or more general-purpose processors including a CPU (Central Processing Unit) or an MPU (Micro Processing Unit). The control unit 11 may include one or more dedicated processors specialized for a specific process. The control unit 11 may include one or more dedicated circuits instead of including the 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 corresponding to one or more wired or wireless LAN (Local Area Network) standards for connecting to the network NW. The communication unit 12 may include a module corresponding to one or more mobile communication standards including LTE (Long Term Evolution), 4G (4th Generation), or 5G (5th Generation). The communication unit 12 communicates with one or more short-range communication standards or specifications including Bluetooth®, AirDrop®, IrDA, ZigBee®, FeliCa®, or RFID. It may include modules and the like. The communication unit 12 transmits and receives arbitrary information via the network NW.

The storage unit 13 includes, but is not limited to, for example, a semiconductor memory, a magnetic memory, an optical memory, or a combination of at least two of them. The semiconductor memory is, for example, RAM or ROM. The RAM is, for example, an SRAM or a DRAM. The ROM is, for example, EEPROM. The storage unit 13 may function as, for example, a main storage device, an auxiliary storage device, or a cache memory. The storage unit 13 may store information on the result analyzed or processed by the control unit 11. The storage unit 13 may store various information and the like related to the operation or control of the information processing device 1. The storage unit 13 may store a system program, an application program, 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 the 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 a private network.

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

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

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

The description of the third block B3 and the fourth block B4 will be omitted in order to avoid duplicate explanations.

The control unit 11 of the information processing apparatus 1 proves for each manifest that the manifest information and the electric power used in the electric furnace EF at the time of processing the waste are the electric power defined by the non-fossil value or the zero emi value. Integrate with proof information. Here, the proof information can be obtained by the following method. In order to realize that the power used in the electric furnace EF is the power defined by the non-fossil value or the zero emi value, first, in the electric furnace EF where the waste described in the target manifest M is treated. The amount of electricity used per ton of waste is calculated from the actual amount of electricity used in 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 electricity used per ton of waste by the amount of waste described in the target manifest M, the actual amount of electricity used to process the target waste is calculated. To. 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 the non-fossil value or the zero emi value.

As a specific example of the method of integrating the manifest information and the proof information, the control unit 11 associates the manifest information M1 and the proof information V1 with the block B1 of the blockchain BC as shown in the manifest DB of FIG. It is stored in the storage unit 13. That is, the manifest information M1 and the certification information V1 are registered as transaction data in the block B1 of the blockchain BC. The registered information is stored as a token of the blockchain BC. As an alternative example, the proof 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 an arbitrary third party on the Internet or the like.

The information processing method by the control unit 11 of the information processing apparatus 1 will be described with reference to FIG. 7.

In step S1, the control unit 11 provides manifest information about waste treatment and proof information certifying that the power used for waste treatment is power defined by non-fossil value or zero emi value. get.

In step S2, the control unit 11 is integrated by associating the manifest information with the proof information.

In step S3, the control unit 11 registers the associated manifest information and certification information in the network NW (for example, the 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 example]
In the above embodiment, the manifest information and the proof information are associated and stored in the storage unit 13. However, the control unit 11 may not be able to obtain certification information such as a green power certificate. Therefore, when the power generation process of the electric power purchased by the electric power consumer is a process in which renewable energy and energy other than renewable energy are used in combination, the control unit 11 regenerates the purchased and used electric power. Only power derived from renewable energies can be identified. Such identification can be performed by using arbitrary certification information (for example, carbon dioxide emission factor (residue)) disclosed by an electric power company or the like. The control unit 11 may store the proof 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 renewable energy and energy other than renewable energy in a complex manner, the renewable energy among the purchased and used power is used. Only the power of origin can be identified. The reasons that can be identified are as follows in the "Ministry of Economy, Trade and Industry 15th Comprehensive Resources and Energy Study Group Electricity and Gas Business Subcommittee, Electricity and Gas Basic Policy Subcommittee System Review Working Group (November 28, 2017)". This is because it was stipulated in. That is, if it is assumed that as a result of an auction of a non-fossil certificate subject to FIT (Feed-in Tariff), an unsold non-fossil certificate will be generated, the non-fossil certificate will be the next. It cannot be carried over after the fiscal year and is regarded as "surplus non-fossil electricity equivalent". Regarding the zero-emi value of the environmental value related to the amount of surplus non-fossil electricity, considering that the consumer bears the cost as a FIT levy, etc., the value is not buried, but according to the share of the amount of electricity sold. It was decided to allocate.

In addition, the carbon dioxide emission factors of electric power companies this year may be disclosed after the end of the year. In this case, the carbon dioxide emission factor for this year can be calculated by the control unit 11 by the following procedure.
Procedure 1. From the carbon dioxide emission factor and non-fossil power ratio of the previous year, the usable amount of non-fossil power on the basis of the previous year is estimated, and the estimation result is reflected in the planned power plan to be used at the factory this year. As an alternative example, for the non-fossil power ratio, the renewable energy ratio target value for this year described in the energy environment plan published by any local government may be adopted.
Step 2. We will allocate non-fossil electricity this year in response to customer requests.
Step 3. When the carbon dioxide emission factor for this year is released, the actual results of the allocation of non-fossil electricity and the allocation of the remaining electricity other than non-fossil electricity will be adjusted and finalized.

If the power generation process is a process that uses both renewable energy and energy other than renewable energy in a complex manner, the method of specifying only the power derived from renewable energy among the purchased and used power is as follows. Can be obtained by In order to realize that the power used in the electric furnace EF is the power defined by the non-fossil value or the zero emi value, first, the factory power consumption corresponding 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 at one time in the electric furnace EF. Next, the amount of electric power derived from renewable energy is calculated by multiplying the amount of electric power used for one heat by the ratio of renewable energy disclosed by the electric power company or the like. Then, the power consumption per ton of waste is calculated from the actual factory power consumption in the electric furnace EF in which the waste described in the target manifest M is treated. Next, by multiplying the amount of electricity used per ton of waste by the amount of waste described in the target manifest M, the actual amount of electricity used to process the target waste is calculated. To. By considering 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 by the non-fossil value or the zero emi value.

[effect]
As described above, according to the present embodiment, the waste is treated in an electric furnace using electric power defined by non-fossil value or zero emi value. Here, most of the energy used in the electric furnace (for example, 80% or more) is electric power. Due to this situation, it is possible to offset the carbon dioxide emitted from coke and the like used in the process by procuring electric power defined by non-fossil value or zero emi value (for example, green electric power) and using it in an electric furnace. can. That is, offsetting means calculating the amount of non-fossil power used corresponding to energy such as coke, additionally describing the calculated amount of non-fossil power used in the manifest, and using the non-fossil power used in waste treatment. It is done by associating with waste. Therefore, the feasibility of carbon-neutral waste treatment can be easily enhanced. Furthermore, since the residue in the electric furnace after the waste is dissolved is almost zero, almost 100% recycling is possible. Therefore, the life of the landfill site is extended.

In contrast, the energy used to dispose of waste in incinerators ranges from city gas, natural gas, heavy oil, kerosene and the like. In this case, the proof of carbon neutral requires a complicated calculation based on the LCA evaluation, and even if the calculation is performed, it is impossible to realize carbon neutral.

Further, according to the present embodiment, the recycling method is a method of treating waste in an electric furnace using electric power defined by non-fossil value or zero emi value, and recycling the treated waste as a recycling raw material. Since the residue in the electric furnace after the waste is dissolved is almost zero, almost 100% recycling is possible. Therefore, the life of the landfill site is extended.

Further, according to the present embodiment, the information processing apparatus 1 has manifest information about waste and proof that the electric power used for processing the waste is the electric power defined by the non-fossil value or the zero emi value. Associate with information. This configuration makes it easy to prove that the waste treatment is carbon neutral.

Further, according to the present embodiment, the network NW includes a blockchain network, and the associated manifest information and certification information are registered in the blockchain. When the blockchain technology is used in this way, the registration information is distributed and shared by all the nodes. That is, no central administrator is required. Therefore, the following effects are achieved.
-Difficult to tamper with-There is no system down because there is no single point of failure-Since data sharing with other systems is easy, the information processing device 1 can realize a system with high safety and low cost. .. Furthermore, since all data is recorded on the blockchain, traceability is ensured.

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

Further, according to the present embodiment, when the power generation process of the purchased electric power is a process in which renewable energy and energy other than renewable energy are used in combination, the control unit 11 is derived from the renewable energy among the electric power. Identifies the power of the electricity and correlates the proof information certifying that the identified power is from renewable energy with the manifest information about the waste processed in the electric furnace. With this configuration, the information processing apparatus 1 can prove that the waste treatment is partially carbon-neutral even when energy other than renewable energy is used in the power generation process.

This disclosure will be described with reference to the drawings and examples, but it should be noted that those skilled in the art may make various modifications and modifications based on the present disclosure. Other changes are possible without departing from the spirit of this disclosure. For example, the functions and the like 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 or divided into one.

For example, in the above embodiment, a program that executes all or part of the functions or processes of the information processing apparatus 1 can be recorded on a computer-readable recording medium. Computer-readable recording media include non-temporary computer-readable media, such as magnetic recording devices, optical discs, opto-magnetic recording media, or semiconductor memories. The distribution of the program is carried out, for example, by selling, transferring, or renting 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. Further, 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. The program may also be provided as a program product. The present disclosure can also be realized as a program that can be executed by a processor.

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