[0002] In related technologies, current carbon emission reduction accounting for textile fabric recycling often uses traditional landfill / incineration baseline data. For example, the landfill carbon emission factor is 1.8tCO2 / t, which cannot dynamically reflect the regional carbon emission reduction potential. It also does not integrate the impact of process path selection on carbon emission reduction, resulting in a high error in the calculation of carbon emission reduction. As a result, the calculation results of carbon emission reduction in the textile fabric recycling process are not accurate enough. At the same time, the emission reduction benefits of the textile fabric recycling process have not been fully quantified. Summary of the Invention

[0018] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0019] The following describes, with reference to the accompanying drawings, a method, device, electronic device, and medium for obtaining carbon emission reductions from closed-loop recycling of textile fabrics according to an embodiment of the present application.

[0020] Figure 1 This is a flow chart of a method for obtaining carbon emission reductions from closed-loop recycling of textile fabrics according to an embodiment of the present application. Figure 1 As shown, the method includes:

[0021] S101, obtaining the original weight of the textile fabric.

[0022] It should be noted that the present application does not limit the specific method for obtaining the original weight of the textile fabric, which can be selected according to actual conditions.

[0023] Optionally, the original weight of the textile fabric can be obtained based on a weight sensor.

[0024] S102: Obtain candidate carbon emission reduction methods for textile fabrics, and select a target carbon emission reduction method for textile fabrics from the candidate carbon emission reduction methods.

[0025] It should be noted that candidate carbon emission reduction methods include but are not limited to: physical recovery (e.g. mechanical opening), chemical recovery (e.g. solvent depolymerization), and biological recovery (e.g. enzyme catalysis).

[0026] In the embodiment of the present application, after obtaining the candidate carbon emission reduction methods for the textile fabric, any one of the candidate carbon emission reduction methods can be selected as the target carbon emission reduction method for the textile fabric.

[0027] S103: Based on the original weight, obtaining the target carbon emission of the textile fabric under the target carbon emission reduction mode, and obtaining the baseline carbon emission of the textile fabric under the baseline carbon emission reduction mode.

[0028] In an embodiment of the present application, a first target carbon emission amount of the textile fabric during recycling and transportation can be obtained based on the original weight, and parameter data of the textile fabric can be obtained, wherein the parameter data includes at least a material ratio, a loss factor, and a grid emission factor. Based on the material ratio, the loss factor, and the original weight, a first weight of the first textile fabric corresponding to each material is determined, energy consumption data of the target carbon emission reduction method is obtained, a second target carbon emission amount of the first textile fabric during reprocessing is obtained based on the first weight, the energy consumption data, and the grid emission factor, a recycled material blending ratio is obtained, a second weight of the second textile fabric corresponding to each material is obtained based on the first weight and the recycled material blending ratio, a third target carbon emission amount of the second textile fabric corresponding to each material during the production process is obtained based on the second weight, and a target carbon emission amount is obtained based on the first target carbon emission amount, the second target carbon emission amount, and the third carbon emission reduction amount.

[0029] In an embodiment of the present application, a first baseline carbon emission amount of the textile fabric during landfilling / or incineration can be obtained based on the original weight, and a third weight of the third textile fabric corresponding to each material can be obtained based on the first weight and the second weight. Based on the third weight, a second baseline carbon emission amount of the third textile fabric corresponding to each material during the production process is obtained, and a baseline carbon emission amount is obtained based on the first baseline carbon emission amount and the second baseline carbon emission amount.

[0030] S104: Obtain carbon emission reduction of textile fabrics based on the target carbon emission and the baseline carbon emission.

[0031] In the implementation of this application, after obtaining the target carbon emissions and the baseline carbon emissions, the difference between the baseline carbon emissions and the target carbon emissions can be obtained, and the difference can be determined as the carbon emission reduction of the textile fabric.

[0032] For example, if the target carbon emission of textile fabrics is C and the baseline carbon emission of textile fabrics is C*, then the carbon emission reduction of textile fabrics CER = C* - C.

[0033] The present application proposes a method for obtaining carbon emission reductions from closed-loop recycling of textile fabrics. The method obtains the original weight of the textile fabric, obtains candidate carbon emission reduction methods for the textile fabric, selects a target carbon emission reduction method for the textile fabric from the candidate carbon emission reduction methods, obtains the target carbon emissions of the textile fabric under the target carbon emission reduction method based on the original weight, and obtains the baseline carbon emissions of the textile fabric under the baseline carbon emission reduction method. The carbon emission reductions of the textile fabric are obtained based on the target carbon emissions and the baseline carbon emissions. Thus, the present application integrates the impact of different carbon emission reduction methods on carbon emission reductions by obtaining the target carbon emissions of the textile fabric under the target carbon emission reduction method. Based on the target carbon emissions and the baseline carbon emissions, the carbon emission reductions of the textile fabric can be obtained more accurately and efficiently. The carbon emission reduction benefits of the textile fabric recycling process are fully quantified.

[0034] Figure 2 This is a flow chart of a method for obtaining carbon emission reductions from closed-loop recycling of textile fabrics according to an embodiment of the present application. Figure 2 , the specific process of obtaining the target carbon emissions of textile fabrics under the target carbon emission reduction method based on the original weight is explained, including the following steps:

[0035] S201: Obtain a first target carbon emission amount of the textile fabric during recycling and transportation based on the original weight.

[0036] In an embodiment of the present application, the recycling transportation distance of the textile fabric during the recycling transportation process and the carbon emission factor of the recycling transportation vehicle can be obtained, and the product of the original weight, the recycling transportation distance and the carbon emission factor can be obtained. Based on the product, the first target carbon emission amount C1 of the textile fabric during the recycling transportation process is determined.

[0037] For example, if the textile fabric is waste denim with an original weight of 1 ton, the transportation distance is 200 km, and the carbon emission factor of the diesel truck is 2.89 kg CO2 / km·t, then the first target carbon emission C1 of the textile fabric during the recycling and transportation process is 578 kg, that is, 578 kg of carbon dioxide emissions (200 km × 2.89 kg CO2 / km·t × 1 ton).

[0038] S202: Obtain parameter data of textile fabrics, wherein the parameter data at least includes material ratio, loss factor, and grid emission factor.

[0039] Optionally, with respect to the material ratio of the textile fabric, the material ratio of the textile fabric may be obtained based on an infrared spectrometer.

[0040] For example, if the textile fabric is waste denim, the material purity of the waste denim is tested based on an infrared spectrometer to obtain the material ratio of the textile fabric as: 60% cotton and 40% polyester.

[0041] It should be noted that the international carbon footprint database lacks measured data from Chinese recycled textile companies, forcing export companies to adopt relatively high grid emission factors. At the same time, brands often require suppliers to provide regional grid emission factors. However, existing technologies cannot dynamically match grid emission factors.

[0042] In an embodiment of the present application, the location information and timestamp information of the production of textile fabrics can be obtained, and based on the location information and timestamp information, a pre-built grid emission factor database is queried for dynamic matching to obtain the grid emission factor corresponding to the textile fabric.

[0043] The power grid emission factor database includes the power grid emission factors corresponding to each location and time interval.

[0044] For example, the power grid emission factor in North China in the first half of 2022 is a, and the power grid emission factor in North China in the second half of 2022 is b. If the location information of textile product production is North China, China, and the timestamp information is October 2, 2022, then the power grid emission factor of textile fabrics is b.

[0045] S203: Determine a first weight of the first textile fabric corresponding to each material according to the material proportion, the loss factor, and the original weight.

[0046] In an embodiment of the present application, after obtaining the material proportion, loss factor and original weight, the product of the material proportion, loss factor and original weight can be obtained, and the first weight of the first textile fabric corresponding to each material can be determined based on the product.

[0047] For example, if the textile fabric is waste denim, with an original weight of 1 t, a material ratio of 60% cotton and 40% polyester, and a loss factor of 10%, the weight of the first textile fabric corresponding to cotton is 0.54 t (1 t × 90% × 60%), and the weight of the first textile fabric corresponding to polyester is 0.36 t (1 t × 90% × 40%).

[0048] S204: Obtain energy consumption data of the target carbon emission reduction method, and obtain a second target carbon emission amount of the first textile fabric during the reprocessing process based on the first weight, the energy consumption data, and the grid emission factor.

[0049] Alternatively, if the target carbon emission reduction method is chemical recycling, smart meters can be installed in the depolymerization reactor and the spinning machine, and based on the smart meters, the energy consumption data of the depolymerization reactor and the energy consumption data of the spinning machine can be determined respectively.

[0050] It should be noted that the first textile fabric can be understood as recycled material, which can be used again to produce new products or used as raw material.

[0051] For example, if the target carbon emission reduction method is physical recycling, the energy consumption data can be 0.8-1.2kWh / kg; if the target carbon emission reduction method is chemical recycling, the energy consumption data can be 2.5-4.0kWh / kg.

[0052] In the embodiment of the present application, the product of the first weight, the energy consumption data, and the grid emission factor may be obtained, and the second target carbon emission amount of the first textile fabric during the reprocessing process may be determined based on the product.

[0053] For example, for the first textile fabric corresponding to cotton, if the first weight is 0.54t (540kg), the energy consumption data is 3kWh / kg, and the grid emission factor is 0.763kgCO2 / kWh, the carbon emissions of the first textile fabric corresponding to cotton during the reprocessing process are 1236.06kg, that is, 1236.06kg of carbon dioxide emissions (540kg×3kWh / kg×0.763kgCO2 / kWh); the weight of the first textile fabric corresponding to polyester is The amount is 0.36 t (1 t × 90% × 40%); for the first textile fabric corresponding to polyester, if the first weight is 0.36 t (360 kg), the energy consumption data is 3 kWh / kg, and the grid emission factor is 0.763 kg CO2 / kWh, the carbon emissions of the first textile fabric corresponding to polyester during the reprocessing process are 820.8 kg, that is, 820.8 kg of carbon dioxide emissions (360 kg × 3 kWh / kg × 0.763 kg CO2 / kWh).

[0054] In the embodiment of the present disclosure, after obtaining the carbon emissions of the first textile fabric corresponding to each material, the carbon emissions of the first textile fabric corresponding to each material can be summed to obtain a second target carbon emissions C2 of the first textile fabric during the reprocessing process.

[0055] For example, for a first textile fabric corresponding to cotton and a first textile fabric corresponding to polyester, if the carbon emissions of the first textile fabric corresponding to cotton during the reprocessing process are 1236.06 kg and the carbon emissions of the first textile fabric corresponding to polyester during the reprocessing process are 820.8 kg, then the second target carbon emissions C2 of the first textile fabric during the reprocessing process is 2056.86 kg (1236.06 kg + 820.8 kg).

[0056] S205: Obtain a blending ratio of recycled materials, and obtain a second weight of the second textile fabric corresponding to each material according to the first weight and the blending ratio of recycled materials.

[0057] The second textile fabric can be understood as new material, that is, not recycled or reused.

[0058] Among them, the blending ratio of recycled materials is greater than or equal to 50%.

[0059] For example, if the blending ratio of recycled materials is 50%, that is, the blending ratio of recycled materials to new materials is 1:1, if the first weight of the first textile fabric (old material) corresponding to cotton is 0.54t, then the second weight of the second textile fabric (new material) corresponding to cotton is 0.54t; if the first weight of the first textile fabric (old material) corresponding to polyester is 0.36t, then the second weight of the second textile fabric (new material) corresponding to polyester is 0.36t.

[0060] S206: Based on the second weight, obtain a third target carbon emission amount during the production process of the second textile fabric corresponding to each material.

[0061] Optionally, a public database can be queried to determine the carbon emissions of the second textile fabric corresponding to each material produced by the recycling plant based on the second weight, and the carbon emissions of the second textile fabric corresponding to each material can be summed to obtain a third target carbon emissions C3 during the production process of the second textile fabric.

[0062] For example, for the second textile fabric corresponding to cotton, if the second weight is 0.54 t, by querying the public database, the carbon emissions from producing 0.54 t of the second textile fabric corresponding to cotton are determined to be a1. For the second textile fabric corresponding to polyester, if the second weight is 0.36 t, by querying the public database, the carbon emissions from producing 0.36 t of the second textile fabric corresponding to polyester are determined to be a2. Then, the third target carbon emissions C3 is a1 + a2.

[0063] S207: Obtain a target carbon emission amount according to the first target carbon emission amount, the second target carbon emission amount, and the third target carbon emission reduction amount.

[0064] In an embodiment of the present application, after obtaining the first target carbon emissions, the second target carbon emissions and the third target carbon emission reduction, the first target carbon emissions, the second target carbon emissions and the third target carbon emission reduction can be summed to obtain the target carbon emissions C.

[0065] The present application proposes a method for obtaining carbon emission reductions from closed-loop recycling of textile fabrics. The method comprises obtaining a first target carbon emission amount of the textile fabric during recycling and transportation based on the original weight, obtaining parameter data of the textile fabric, wherein the parameter data includes at least material proportion, loss factor, and grid emission factor. The method then determines a first weight of the first textile fabric corresponding to each material based on the material proportion, loss factor, and original weight, obtains a recycled material blending ratio, obtains a second weight of the second textile fabric corresponding to each material based on the first weight and the recycled material blending ratio, obtains a third target carbon emission amount during the production process of the second textile fabric corresponding to each material based on the second weight, and obtains a target carbon emission amount based on the first target carbon emission amount, the second target carbon emission amount, and the third target carbon emission reduction amount. Thus, the present application can obtain the target carbon emission amount more accurately and can fully quantify the carbon emission reduction benefits of the textile fabric recycling process, thus having important environmental and economic value.

[0066] Figure 3 This is a flow chart of a method for obtaining carbon emission reductions from closed-loop recycling of textile fabrics according to an embodiment of the present application. Figure 3The specific process of obtaining the baseline carbon emissions of the textile fabric under the baseline carbon emission reduction method is explained, including the following steps:

[0067] S301: Obtain a first benchmark carbon emission amount of the textile fabric during landfilling or incineration based on the original weight.

[0068] Optionally, a landfill carbon emission factor of the textile fabric may be obtained, and a first benchmark carbon emission amount C1* of the textile fabric during the landfill process may be obtained based on the original weight and the landfill carbon emission factor.

[0069] Optionally, the incineration carbon emission factor of the textile fabric may be obtained, and based on the original weight and the incineration carbon emission factor, a first benchmark carbon emission amount C1* of the textile fabric during the incineration process may be obtained.

[0070] S302: Obtain a third weight of a third textile fabric corresponding to each material according to the first weight and the second weight.

[0071] Among them, the third textile fabric can be understood as being produced entirely from new materials.

[0072] For example, if the first weight of the first textile fabric (old material) corresponding to cotton is 0.54 t and the second weight of the second textile fabric (new material) corresponding to cotton is 0.54 t, then the third weight of the third textile fabric corresponding to cotton is 1.08 t. If the first weight of the first textile fabric (old material) corresponding to polyester is 0.36 t and the second weight of the second textile fabric (new material) corresponding to polyester is 0.36 t, then the third weight of the third textile fabric corresponding to cotton is 0.72 t.

[0073] S303: Based on the third weight, obtain a second baseline carbon emission amount during the production process of the third textile fabric corresponding to each material.

[0074] For example, for the third textile fabric corresponding to cotton, if the third weight is 1.08 t, by querying the public database, the carbon emissions from producing 1.08 t of the third textile fabric corresponding to cotton are determined to be b1. For the third textile fabric corresponding to polyester, if the third weight is 0.72 t, by querying the public database, the carbon emissions from producing 0.72 t of the third textile fabric corresponding to polyester are determined to be b2. In this case, the second baseline carbon emissions C2* is b1 + b2.

[0075] It should be noted that, under the target carbon emission reduction method, the sum of the second target carbon emissions of the first textile fabric (old material) in the reprocessing process and the third target carbon emissions of the second textile fabric (new material) in the production process can be obtained, which can be understood as the carbon emissions required to produce the third weight of the third textile fabric (new material). Under the baseline carbon emission reduction method, it is the second baseline carbon emissions. According to the carbon emissions required to produce the third weight of the third textile fabric (new material) and the second baseline carbon emissions, the carbon offset and cost savings of replacing old materials with new materials can be calculated, that is, the carbon emission reduction benefits and economic costs can be quantified.

[0076] S304: Obtain a benchmark carbon emission amount according to the first benchmark carbon emission amount and the second benchmark carbon emission amount.

[0077] In the embodiment of the present application, after the first baseline carbon emissions and the second baseline carbon emissions are obtained, the first baseline carbon emissions and the second baseline carbon emissions may be summed to obtain the baseline carbon emissions C*.

[0078] The present application proposes a method for obtaining carbon emission reductions from closed-loop recycling of textile fabrics. The method obtains a first baseline carbon emission amount of the textile fabric during landfilling / or incineration based on the original weight, obtains a third weight of a third textile fabric corresponding to each material based on the first weight and the second weight, obtains a second baseline carbon emission amount of the third textile fabric corresponding to each material during the production process based on the third weight, and obtains a baseline carbon emission amount based on the first baseline carbon emission amount and the second baseline carbon emission amount. Thus, the present application ensures the accuracy of the obtained baseline carbon emission amount, laying the foundation for more accurate acquisition of carbon emission reductions.

[0079] In this embodiment of the present application, after obtaining the target carbon emissions and the baseline carbon emissions, the difference between the baseline carbon emissions and the target carbon emissions can be obtained to obtain the carbon emission reduction rate (CER) of the textile fabric. After obtaining the carbon reduction, the carbon emission reduction range of the textile fabric under a preset confidence level can be obtained.

[0080] Figure 4 This is a flow chart of a method for obtaining carbon emission reductions from closed-loop recycling of textile fabrics according to an embodiment of the present application. Figure 4 The specific process of obtaining the carbon emission reduction range of textile fabrics under a preset confidence level is explained, including the following steps:

[0081] S401: Obtain a carbon emission reduction error value under a preset confidence level.

[0082] It should be noted that the present application does not limit the setting of the preset confidence level, for example, the preset confidence level is 95%.

[0083] In an embodiment of the present application, the variable data and carbon emission reduction amount in the target carbon emission reduction method can be modeled to obtain a carbon emission reduction amount calculation model, obtain sample variable data, obtain sample carbon emission reduction amount based on the sample variable data and the carbon emission reduction amount calculation model, obtain the mean and standard deviation of the sample carbon emission reduction amount, obtain the carbon emission reduction amount interval under a preset confidence level based on the mean and standard deviation of the sample carbon emission reduction amount, and obtain the carbon emission reduction amount error value under the preset confidence level based on the carbon emission reduction amount interval under the preset confidence level.

[0084] For example, if the target carbon emission reduction method is physical recycling, the variable data can be sorting purity, recycling transportation distance, etc.

[0085] S402: Obtaining a carbon emission reduction range of the textile fabric under a preset confidence level according to the carbon emission reduction error value and the carbon emission reduction of the textile fabric.

[0086] For example, if the confidence level is 95% and the carbon emission reduction error is ±5%, then the carbon emission reduction range of textile fabrics at a 95% confidence level is [CER-5%, CER+5%].

[0087] It should be noted that relevant technologies cannot monitor carbon emission data and energy consumption data in each process in real time. At the same time, the data sovereignty mechanism is imperfect, and encrypted transmission between supply chain companies is not achieved through alliance chains such as modular distributed ledgers (Hyperledger Fabric), resulting in poor credibility of data between supply chain companies.

[0088] In an embodiment of the present application, for the target carbon emission reduction method, the carbon emission data of the textile fabric in each process can be hashed to obtain a first hash value of the carbon emission data of the textile fabric in each process, and the material ratio of the textile fabric can be hashed to obtain a second hash value of the material ratio of the textile fabric. The first hash value and the second hash value are stored in the blockchain to improve the credibility of the data.

[0089] In an embodiment of the present application, in response to the recycled material blending ratio passing the Global Recycled Standard (GRS) certification, a GRS certification number is generated, and a carbon emission reduction report for the textile fabric is generated based on the first hash value, the second hash value and the GRS certification number.

[0090] Among them, the carbon emission reduction report of textile fabrics can be in PDF format and comply with the carbon emission reduction report of China Certified Emission Reduction (CCER), which can support subsequent carbon asset trading.

[0091] Optionally, the carbon emission reduction report may also include a carbon label printing link, which is connected to the carbon label printing link through an application programming interface to generate a carbon footprint label containing a QR code, so that the carbon footprint tracking report can be traced by scanning the QR code to achieve accurate tracking.

[0092] The present application proposes a method for obtaining carbon emission reductions from closed-loop recycling of textile fabrics. The method obtains a carbon emission reduction error value under a preset confidence level, and obtains a carbon emission reduction range of the textile fabric under the preset confidence level based on the carbon emission reduction error value and the carbon emission reduction of the textile fabric. Thus, the present application can obtain a carbon emission reduction range of the textile fabric under the preset confidence level based on the carbon emission reduction error value and the carbon emission reduction of the textile fabric, and can correct the carbon emission reduction of the textile fabric to ensure the reliability of the carbon emission reduction range of the textile fabric.

[0093] Figure 5 This is a structural diagram of a device for obtaining carbon emission reductions from closed-loop recycling of textile fabrics according to an embodiment of the present application. Figure 5 As shown, a device 1000 for obtaining carbon emission reductions from closed-loop recycling of textile fabrics includes a first obtaining module 110, a selection module 120, a second obtaining module 130, and a third obtaining module 140, wherein:
