Background Technology

[0002] As a key hub of the circular economy, the importance of waste material trading platforms is becoming increasingly prominent. However, the current functions of these platforms mainly focus on transaction matching, lacking scientific and convenient methods for quantifying and tracing the carbon emission reduction benefits generated during the recycling of traded products, especially waste materials.

[0003] Currently, the mainstream method for measuring a product's carbon footprint is life cycle assessment. However, this method is typically complex, costly, and time-consuming, requiring a specialized team to execute it, making it difficult to meet the urgent need of numerous small and medium-sized enterprises in the recycled resources trading market for rapid and low-cost access to carbon footprint data. Furthermore, recycled resources trading products are diverse, with complex origins and varied logistics routes, and their carbon emissions involve multiple stages such as recycling, transportation, dismantling, and remanufacturing. Traditional methods struggle to establish standardized accounting models to adapt to the platform-based batch processing requirements.

[0004] Therefore, there is an urgent need to propose a carbon emission traceability technology solution that can be embedded in a waste material trading platform, integrates scientific rigor and convenience, and supports flexible result correction and value chain sharing. Summary of the Invention

Detailed Implementation

[0023] Embodiments of this application will now be described in more detail with reference to the accompanying drawings. While some embodiments of this application are shown in the drawings, it should be understood that this application can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of this application. It should be understood that the drawings and embodiments of this application are for illustrative purposes only and are not intended to limit the scope of protection of this application.

[0024] It should be understood that the steps described in the method embodiments of this application may be performed in different orders and / or in parallel. Furthermore, the method embodiments may include additional steps and / or omit the steps shown. The scope of this application is not limited in this respect.

[0025] As described in the background section, existing carbon accounting tools are mostly independent professional software or services that fail to deeply integrate with waste material trading platforms. They cannot automatically retrieve transaction data (such as product categories, transaction quantities, and logistics information), forcing users to manually input data repeatedly, resulting in low efficiency and a high risk of errors. Furthermore, there is a lack of refined, configurable carbon emission traceability models for different transaction purposes (such as "remanufacturing" versus "general recycling") and different product categories (such as "metal and rubber parts"). Existing methods struggle to intelligently identify transaction scenarios and match corresponding accounting logic, failing to achieve "one-click" intelligent estimation. Moreover, there are issues with data reliability and flexibility. On one hand, the automated accounting results provided by the platform lack transparency regarding the underlying calculation logic and data sources, affecting the reliability of the results. On the other hand, users cannot verify and correct the automatically generated accounting basis data (activity data), making it difficult to meet personalized requirements for accounting accuracy. The carbon footprint data generated by related technologies is usually confined to a platform or a single user, lacking a convenient and standardized sharing mechanism. This makes it difficult to provide authoritative data input for downstream companies when calculating the carbon footprint of their products and proving the carbon emission reduction benefits of using recycled materials.

[0026] Therefore, there is an urgent need for a carbon emission traceability technology solution that can be embedded in a renewable resource trading platform, combining scientific rigor and convenience, and supporting flexible result correction and value chain sharing.

[0027] refer to Figure 1 This is a schematic diagram of the carbon emission traceability method based on waste material trading provided in the embodiments of this application.

[0028] Step S101: Determine the accounting boundary range for carbon traceability of remanufacturing of waste materials. The accounting boundary range includes the waste material transportation stage, the waste material dismantling stage, the usable material transportation stage, the procurement and transportation stage of other raw and auxiliary materials, and the target product remanufacturing stage; among which, usable materials come from waste materials.

[0029] This step is the primary step in the Life Cycle Assessment (LCA) of the traded waste materials, ensuring the scientific and standardized nature of the accounting and clarifying "where does the remanufacturing of waste materials begin and where does it end," avoiding double counting or omissions. Remanufacturing carbon traceability refers to the process of quantifying and tracking the greenhouse gas emissions of a remanufactured product from cradle to door throughout its complete remanufacturing life cycle using standardized methodologies. Remanufacturing uses professional dismantling, cleaning, testing, repair, and replacement of waste materials to bring them to certain performance and lifespan standards. This is a high-level resource recycling. The key to carbon traceability lies in "source and trajectory." It not only calculates the total carbon emissions but, more importantly, traces the stage at which these emissions originate. The accounting boundary refers to a spatiotemporal and process boundary defined for the system when conducting remanufacturing carbon traceability analysis. It clarifies where the analysis process begins and ends, and which major life cycle stages it includes.

[0030] Step S102: Based on the production process of remanufacturing the target product, determine the carbon emission sources at each stage within the accounting boundary.

[0031] This step breaks down the emission sources at each stage of a typical remanufacturing process. It's important to note that carbon emission sources can be categorized into direct and indirect sources. Direct sources refer to emissions generated by physical or chemical processes within the organization's control. Examples include diesel combustion (CO2) used in dismantling equipment and refrigerant leaks (HFCS) during remanufacturing. Indirect sources refer to emissions from the production of purchased electricity, heat, or steam. This is one of the most significant emission sources in remanufacturing, such as the electrical energy consumed by machine tools and heating equipment.

[0032] Step S103: Based on the survey data of the target product remanufacturing scenario, determine the default values ​​of the activity data in each stage.

[0033] In this step, activity data can refer to the physical or economic quantities that contribute to carbon emissions. Examples include: transport distance (km), electricity consumption (kWh), natural gas consumption (cubic meters), and raw material consumption (kg). "Default value" can be understood as setting a reasonable, industry-average default value for each activity data point based on extensive prior field research and historical data statistics. This allows the platform to immediately generate a benchmark carbon footprint report even without any user data, significantly lowering the barrier to entry for users.

[0034] Step S104: Determine the carbon emission factors of carbon emission sources in each stage.

[0035] In this step, the carbon emission factor is a coefficient representing the carbon dioxide equivalent emission corresponding to a unit of activity data. For example, the average carbon emission factor of a regional power grid (kgCO2e / kWh) or the carbon emission factor of diesel fuel (kgCO2e / L). These carbon emission factors can be derived from recognized and authoritative life cycle databases. Step S105 utilizes the default values ​​of activity data and the carbon emission factors of carbon emission sources in each stage to construct a phased intelligent carbon source tracing and accounting model.

[0036] The intelligent carbon traceability accounting model is not a single formula, but a phased and modular calculation system. It establishes an independent calculation submodule for each phase defined in step S101. Within each submodule, the corresponding activity data list, carbon emission factor, and calculation formula for that phase are embedded. The intelligent carbon traceability accounting model of this application embodiment should allow administrators to configure different activity data lists and default values ​​according to different product categories (such as metal rubber parts and waste plastics), thereby achieving model reuse and expansion.

[0037] Step S106: Based on the actual transaction orders completed on the target platform, generate carbon traceability data for the actual transaction orders through the intelligent carbon traceability accounting model; wherein, the carbon traceability data includes at least the total carbon emissions and the phased carbon emissions for each stage.

[0038] In this step, the system monitors "completed actual transaction orders," automatically extracts key data from the orders (such as product category, transaction weight, and origin and destination of transportation), and matches it with the corresponding intelligent carbon traceability model. The model calls upon order data, default values ​​for activity data, and the emission factor database to automatically complete all calculations. The output is designed to include the total carbon emissions and the phased carbon emissions for each stage.

[0039] As an optional embodiment, the method further includes: in response to a user's instruction to modify the default value of the activity data of the actual transaction order on the target platform, regenerating the phased carbon traceability data of the actual transaction order based on the modified activity data.

[0040] Specifically, this application's embodiments grant users the right to correct their data, transforming the intelligent carbon traceability accounting model from a black box providing an "industry average estimate" into a white box tool that can be verified and optimized by users' own professional knowledge and practical data. Generally, the platform uses default activity data values ​​(industry average, typical survey values) for calculation. The result is the "Platform Intelligent Carbon Traceability Result," a fast and convenient estimate. Furthermore, if the user inputs actual activity data (the true value of this batch of orders), the result is the "User-Corrected Carbon Traceability Result," a more accurate and realistic calculation.

[0041] Based on this, users can place greater trust in results calculated using their own real data. This eliminates users' doubts about whether "default values ​​apply to my specific situation," greatly increasing the credibility and usability of carbon footprint data. The platform is no longer a one-way output of results, but rather an interaction with users. This "modifiable" design gives users a sense of control and establishes a trust relationship between the platform and users. Differences inevitably exist between different users and different transaction orders. This feature allows users to obtain customized carbon footprint reports based on the unique circumstances of each order (such as specific shipping routes or the complexity of specific used parts), achieving refined management. Furthermore, when users repeatedly modify data to seek the most accurate calculation, they are actually comparing the differences in carbon footprint under different data. This process itself can intuitively reveal which activity data has the greatest impact on total carbon emissions, thereby guiding enterprises to focus on key aspects and implement emission reduction measures.

[0042] As an optional embodiment, the method further includes: generating a carbon traceability display interface based on phased carbon traceability data, and displaying the carbon traceability display interface on the target platform.

[0043] Specifically, in this application embodiment, abstract carbon emission data is transformed into an intuitive, readable, and interactive graphical interface through front-end technology.

[0044] As an optional embodiment, the total carbon emissions are the sum of carbon emissions during the waste material transportation stage, the waste material dismantling stage, the usable material transportation stage, the other raw and auxiliary material procurement and transportation stage, and the target product remanufacturing stage.

[0045] Specifically, total carbon emissions are calculated using the following formula, which is embedded in a separate calculation submodule of the intelligent carbon source tracing and accounting model:

[0051] As an optional embodiment, the formula for calculating carbon emissions during the waste dismantling stage is as follows, which is embedded in a separate calculation submodule of the intelligent carbon traceability accounting model:

[0052] in, This indicates the carbon emissions during the dismantling of waste materials, expressed in units of... ; This represents the consumption of the j-th resource or energy in the i-th dismantling stage, expressed in kWh, kg, or... ; This represents the carbon emission factor of the j-th resource or energy source in the i-th dismantling stage, in units of... , or ; This represents the direct greenhouse gas emissions in the i-th dismantling stage, in units of... ; This indicates the weight of the m-th type of non-metallic waste material in the final disposal process, in kg. The carbon emission factor of the m-th type of waste material during the final disposal process is given in units of 1. .

[0053] Furthermore, the carbon emissions during the material transportation phase can be calculated using the following formula, which is embedded in a separate calculation submodule of the intelligent carbon traceability accounting model:

[0054] in, This indicates the carbon emissions during the transportation of usable materials derived from waste, expressed in units of... ; This represents the weight of available materials using transportation method k, in kg. This represents the transport distance using transport mode k, in km. This represents the carbon emission factor based on transportation mode k, in units of... .

[0055] As an optional embodiment, the calculation formula for other raw material procurement and transportation stages is as follows, which is embedded in the independent calculation submodule of the intelligent carbon traceability accounting model:

[0056] in, This represents the total carbon emissions during the procurement and transportation of raw and auxiliary materials, expressed in units of... ; This indicates the carbon emissions during the raw material procurement stage, in units of... ; This indicates the carbon emissions during the transportation of raw and auxiliary materials, expressed in units of... ; This indicates the percentage of recycled material i used, expressed as a percentage. This represents the carbon emissions of recycled material i, in units of... ; This represents the carbon emissions of primary material i, in units of... ; This indicates the weight of the original material i in the component, in kg; This indicates the utilization rate of raw material i during the component processing, expressed in %; The carbon emission factor of primary material i is expressed in units of 1. ; The carbon emission factor of recycled material i is expressed in units of 1. .

[0057] Furthermore, the formula for calculating carbon emissions during the transportation of raw and auxiliary materials is as follows:

[0058] in, This indicates the carbon emissions during the transportation of raw and auxiliary materials, expressed in units of... ; This indicates the weight of raw and auxiliary materials transported by mode k, in kg. This represents the transport distance using transport mode k, in km. This represents the carbon emission factor based on transportation mode k, in units of... .

[0059] Furthermore, the formula for calculating carbon emissions during the product remanufacturing stage is embedded in a separate calculation submodule of the intelligent carbon traceability accounting model:

[0060] in, This indicates the carbon emissions during the product remanufacturing stage, expressed in units of... ; This represents the consumption of the j-th resource or energy in the i-th remanufacturing stage, expressed in kWh, kg, or... ; This represents the carbon emission factor of the j-th resource or energy source in the i-th remanufacturing stage, in units of... , or ; This represents the direct greenhouse gas emissions in the i-th remanufacturing stage, in units of... ; This indicates the weight of the m-th type of waste material in the final disposal process, in kg. The carbon emission factor of the m-th type of waste material during the final disposal process is given in units of 1. In practical implementation, the carbon emission traceability method of this application is applied to the target platform, which is the platform for trading waste materials. For waste materials whose bidding status on the target platform is "sold," a corresponding "carbon emission traceability" module can be added to the waste material information page of the target platform. (Refer to...) Figure 2 This is a schematic diagram of the "carbon emission tracing" module provided in an embodiment of this application. When the user clicks this icon, a pop-up window for "service mode selection" is further provided, see reference. Figure 3This is a schematic diagram of the "Service Method Selection" pop-up window provided in this application embodiment. The "Service Method Selection" pop-up window displays two types of icons: one is "Calculate the carbon footprint of waste materials," and the other is "View the platform's intelligent carbon traceability results." Both icons are preceded by a selection box. When the user clicks the corresponding selection box, the selection box is marked with a "√," indicating that the user has selected that option. In addition, there are "Confirm" and "Cancel" icons. The "Confirm" icon is used to submit the user's selection result, and the "Cancel" icon is used to close the "Service Method Selection" pop-up window. This clear confirmation and exit mechanism provides a clear interaction logic. The design purpose of the "Service Method Selection" is to provide two different levels of service with different costs. Calculating the carbon footprint of waste materials can be understood as corresponding to a paid, professional, and in-depth calculation service. Viewing the platform's intelligent carbon traceability results can be understood as corresponding to a free, fast, and intelligent estimation calculation service.

[0061] Furthermore, when users click the "Calculate Carbon Footprint of Waste Materials" icon, they are redirected to the target platform's carbon footprint modeling platform. This platform supports rapid and accurate modeling of remanufactured products from waste materials, enabling precise calculation and comprehensive management of product carbon footprints. (Reference) Figure 4 This is a schematic diagram of the "Carbon Footprint Modeling Platform" page provided in the embodiments of this application.

[0062] Taking a traded waste material, specifically an electric fan, as an example, in the construction of its life cycle model, the fan can be disassembled into a rotor, magnet, control circuit, casing, power plug, and switch. The rotor can be further disassembled into magnets, fan blades, and shaft. The magnets can be further disassembled into silicon steel sheets, spools, and bearings. The control circuit can be further disassembled into an IC sensing magnet. Based on this precise disassembly, each component can be accurately assigned a value, namely its corresponding material type and weight, and the carbon emission factor of that material can be retrieved from the database. The carbon footprint calculated in this way is far more accurate than the industry average estimate.

[0063] In addition, the target platform can provide a component library, allowing users to build virtual components such as... Figure 4 The system shows a hierarchical structure of electric fans, specifying the material and weight of each end component (such as "silicon steel sheet"), and the platform backend can automatically link to a vast database of carbon emission factors.

[0064] Furthermore, when a user clicks "View Platform Smart Carbon Traceability Results," the platform intelligently identifies the category of the traded product, matches the corresponding smart carbon emission traceability model, and calls upon the platform's internal transaction data to automatically calculate the carbon emissions from the waste material transaction. Users can modify activity data, stage names, and other information based on the aforementioned general model to correct the carbon traceability results.

[0065] In addition, the platform also provides a function for sharing accounting results. This allows the carbon traceability results to be generated into a shared link, providing data support for downstream users to calculate the carbon footprint of their products and accurately measure the carbon emission reduction benefits of using recycled resources.

[0066] Service method: Logged-in users can view the results for free.

[0067] Embedding locations include: Click the “Carbon Emission Tracing” module icon on the platform’s official website interface, and then check “View Platform Smart Carbon Tracing Results” in the “Service Method Selection” pop-up window. The “View Platform Smart Carbon Tracing Results” interface pop-up window will then appear.

[0068] ② Add a "Carbon Services" module to the platform's operating system, and create a "Carbon Emission Tracing" sub-section under this module to store the carbon emission tracing results for each transaction made by platform users; or create a "Carbon Emission Tracing" sub-section within the existing "Personal Information" module to store the carbon emission tracing results for each transaction made by platform users. (Reference) Figure 5 This is a schematic diagram of the "Carbon Emission Tracing" sub-section page provided in this application embodiment. Taking axial remanufacturing as an example, its total carbon emissions are 15,000. Click to view / modify the "View Platform Smart Carbon Traceability Results" interface corresponding to this transaction information.

[0069] It should be noted that the examples in this application are only feasible and reasonable examples. Specific content such as "subject matter", "transaction time", and "carbon emission unit" can be flexibly set according to actual transaction orders or default activity data.

[0070] refer to Figure 6 This is a schematic diagram of the intelligent carbon traceability results page provided in this application embodiment. An example is given where the business type is "remanufactured products" and the primary resource category is "metal and rubber parts raw materials." When activity data is missing, the relevant field content is displayed as "—".

[0071] Figure 6 It is the core display and interactive page of the "Platform Intelligent Carbon Traceability Results". It fully presents the model-based automatic calculation results and allows users to check and share them.

[0072] The display interface mainly includes several key areas, namely the header information area, phased traceability details, accounting results overview, and core interactive icons.

[0073] The header information area includes elements / content such as quantity, unit of measurement, and type of traded product. This information can be obtained by accessing transaction data from the platform, identifying which order is currently being processed. When a user modifies the activity data, some content can be updated synchronously. The header information area also includes images of the traded product, displaying pictures to make the page more intuitive.

[0074] The phased traceability details include elements / content such as the transportation of waste metal and rubber parts, the stripping of waste metal and rubber parts, the transportation of the stripped metal skeleton, the procurement and transportation of other raw and auxiliary materials, and the remanufacturing of metal and rubber parts. The waste metal and rubber parts transportation section includes the transportation method and carbon emissions. The default transportation method is "general truck transportation," and the carbon emissions are calculated using an intelligent carbon emission traceability model based on user-submitted activity data.
