[0002] Polyester, which is a representative recyclable material resulting from resource circulation, is widely used across all industrial fields, including electrical and electronic applications, automotive applications, textile applications, and packaging applications. Such polyester material, depending on the manufacturing method during productization, is distributed in various processed forms, and the ease of collection and classification varies according to the processed and distributed form, resulting in differences in recycling rates.

[0003] Meanwhile, the success of the system for processing resource circulation, which includes classification, preprocessing, pulverization, materialization, productization, and collection of various recyclable materials such as polyester, may be determined by optimizing carbon emissions and cost over the entire life cycle of the corresponding product through tracking of resource-circulated raw materials.

[0005] However, the problem to be solved by the disclosure is not limited to that mentioned above, and other problems to be solved that are not mentioned may be clearly understood by those of ordinary skill in the art to which the disclosure belongs from the following description.

[0006] According to a first aspect, there is provided a method for providing solutions for a value chain for resource circulation, to be performed by a computer apparatus that supports the value chain for the resource circulation, wherein the value chain for the resource circulation produces resource-circulated products through recycling treatment for waste, the method comprising: classifying for at least a part of the waste as a target for a closed-loop in which at least a portion of the resource-circulated products is re-circulated as a secondary waste for the recycling treatment, the resource-circulated products being produced through the recycling treatment and a predetermined chemical recycling treatment to have a shape corresponding to shape of the waste in order that the portion of the produced resource-circulated products is reusable for the secondary waste; and classifying at least a portion of the target for the closed-loop as a resource circulation material that is to be processed into a chemical recycling raw material to be input into a production process of the resource-circulated products.

[0008] According to a third aspect, there is provided a computer-readable storage medium storing a computer program, in which the computer program includes instructions that, when executed by a processor, cause the processor to perform the method for providing solutions for a value chain for resource circulation.

[0009] According to a fourth aspect, there is provided a computer program stored in a computer-readable storage medium, in which the computer program includes instructions that, when executed by a processor, cause the processor to perform the method for providing solutions for a value chain for resource circulation.

[0010] According to a fifth aspect, there is provided a system for processing resource circulation.

[0023] Hereinafter, embodiments of the disclosure will be described in detail with reference to the accompanying drawings so that those with ordinary skill in the art to which the disclosure pertains may easily carry out the embodiments. Further, a part irrelevant to the description will be omitted to clearly describe the disclosure with reference to the drawings.

[0024] FIG. 1 is a conceptual diagram for describing a closed-loop resource circulation structure supported by a system for processing resource circulation according to an embodiment of the disclosure.

[0025] With reference to FIG. 1, a closed-loop resource circulation structure refers to a structure in which resources circulate in the sequence of waste collection, waste classification and preprocessing, material production using the preprocessed waste, consumption and disposal during the production process of the products using the material, and collection of waste after product use, etc. Such a closed-loop resource circulation structure enables resource-circulated products to be produced to be identical or similar to original waste through recycling treatment and specific chemical recycling treatment to allow at least a portion of the resource-circulated products to be re-circulated as waste for recycling treatment. Although the implementation of such a closed-loop resource circulation structure has constraints, such as requiring that the waste be industrial waste or post-industrial waste (PIR) discharged during the manufacturing process, it has advantages in that the cost required for waste collection and waste classification and preprocessing is reduced, and the quality of the produced resource-circulated products is superior.

[0026] FIG. 2 is a block diagram of the system for processing resource circulation according to an embodiment of the disclosure, and FIG. 3 is a block diagram of a computer apparatus that may be mounted on a waste classification device constituting the system for processing resource circulation according to an embodiment of the disclosure.

[0027] With reference to FIGS. 2 and 3, a system 200 for processing resource circulation according to an embodiment includes a waste collection device 210, a waste classification device 220, and a product production device 230.

[0028] The waste collection device 210 collects waste of at least a portion of the resource-circulated products and provides it to the waste classification device 220. For example, the waste collection device 210 may include hardware components capable of collecting and transporting waste that may be referred to as used resource-circulated products. Alternatively, the waste collection device 210 may be implemented separately from the hardware components and may be interlocked therewith. In this case, the waste collection device 210 may control the process of collecting and transporting waste by the hardware components, and may be communicatively connected to the waste classification device 220 and the product production device 230 to support the closed-loop.

[0029] The waste classification device 220 may include a computer apparatus 310, and the computer apparatus 310 may provide a solution for a resource circulation value chain that produces resource-circulated products through recycling treatment for waste. The computer apparatus 310 may include a memory 311 and a processor 312, and may further include an input / output unit 313 and / or a waste classifier 314. The computer apparatus 310 will be described again below.

[0030] The product production device 230 processes the resource circulation material, which has been preprocessed by the waste classification device 220, into a chemical recycling raw material, and then produces a resource-circulated product. For example, the product production device 230 may include hardware components that produce a resource-circulated product to be identical or similar to original waste through specific chemical recycling treatment. Alternatively, the product production device 230 may be implemented separately from the hardware components that produce the resource-circulated product and may be interlocked therewith. In this case, the product production device 230 may control the resource-circulated product production process performed by the hardware components that produce the resource-circulated product and may be communicatively connected to the waste classification device 220 and the waste collection device 210 to support the closed-loop.

[0031] The waste collection device 210, the waste classification device 220, and the product production device 230 constituting the system 200 for processing resource circulation support a closed-loop in which waste is converted into a resource-circulated product through a chemical recycling raw material, and at least a portion of the converted resource-circulated product is collected and provided to the waste classification device 220 as waste.

[0032] The memory 311 of the computer apparatus 310 stores an application including instructions. For example, the memory 311 may store a computer program configured to perform a method of providing a solution for a resource circulation value chain for a closed-loop resource circulation structure when the instructions are executed by the processor 312.

[0033] By executing the instructions stored in the memory 311, the processor 312 of the computer apparatus 310 loads the application including the instructions and performs the method of providing the solution that is capable of supporting the resource circulation value chain that produces resource-circulated products through recycling treatment for waste. The processor 312 classifies, for the waste, a target for a closed-loop in which resource-circulated products are produced to be identical or similar to original waste through recycling treatment and specific chemical recycling treatment, so that at least a portion of the resource-circulated products is re-circulated as waste for recycling treatment. In addition, the processor 312 classifies at least a portion of the classified target for the closed-loop as a resource circulation material that may be processed into a chemical recycling raw material to be input into the production process of the resource-circulated products.

[0034] Further, the processor 312 may classify, for the waste, a target for an open-loop that is not re-circulated through the closed-loop, and may classify at least a portion of the target for the open-loop as a resource circulation candidate material that allows resource circulation through a chemical recycling treatment other than the specific chemical recycling treatment.

[0035] Additionally, the processor 312 may determine a preprocessing step including at least one of water washing treatment, chemical treatment, or physical treatment based on the material properties of the waste, either before or after classifying the target for the closed-loop. Here, the processor 312 may determine the preprocessing step based on a comparison result between the content of heterogeneous components relative to main components of the waste and a preset threshold value.

[0036] In addition, the processor 312 may acquire information on the corresponding waste and resource circulation tracking information from digital certification information corresponding to the waste, and may classify the target for the closed-loop or classify the target as a resource circulation material based on the information acquired from the digital certification information. Here, the information included in the digital certification information may be ensured for transparency by utilizing a distributed ledger based on blockchain technology. In addition, the digital certification information may be generated or updated by the computer apparatus 310 or by another computer apparatus involved in the resource circulation value chain, such as a computer apparatus mounted on or interlocked with the waste collection device 210 or a computer apparatus mounted on or interlocked with the product production device 230.

[0037] The input / output unit 313 of the computer apparatus 310 may receive data necessary for various processing of the processor 312 as input or output various processing results performed by the processor 312. For example, the input / output unit 313 may include at least one of an interface capable of inputting and outputting various data, an input device through which a user may input various commands, a display or printer that outputs various processing results to be visually recognizable on a screen or printed material, etc., and a communication module capable of transmitting and receiving various data through a communication channel.

[0038] The waste classifier 314 of the computer apparatus 310 may be hardware components configured to identify various types of waste under the control of the processor 312 and to classify and process the various types of waste according to the classification determined by the processor 312. Such a waste classifier 314 employs well-known technical ideas used in conventional waste classification processes for resource recycling, and thus a detailed description thereof will be omitted.

[0039] Hereinafter, with reference to FIGS. 1 to 4, a method of providing solutions of a value chain for resource circulation, which is performed in a system for processing resource circulation according to an embodiment of the disclosure to support a closed-loop resource circulation structure, will be described.

[0040] As previously described with reference to FIG. 2, the waste collection device 210 may include or interlock with hardware components capable of collecting and transporting waste, the computer apparatus 310 of the waste classification device 220 may include the waste classifier 314, and the product production device 230 may include or interlock with hardware components for producing resource-circulated products. Further, these hardware components may be said to employ well-known technical ideas used in conventional waste classification processes for resource recycling. In the following description, focus will be placed on the process in which the waste collected by the waste collection device 210 is provided to the waste classification device 220, and the waste classification device 220 then classifies the waste such that the waste may be supplied to appropriate locations to smoothly support the closed-loop resource circulation structure.

[0041] First, the waste classification device 220 acquires information on the waste provided by the waste collection device 210 and resource circulation tracking information, and classifies a target for the closed-loop among the waste based on the acquired information.

[0042] The closed-loop refers to a structure in which resource-circulated products are produced to be identical or similar to original waste through recycling treatment and specific chemical recycling treatment, so that, after the corresponding resource-circulated products is used, at least a portion thereof is re-circulated as waste for recycling treatment. For example, when the waste is industrial waste or post-industrial waste discharged during a manufacturing process, the corresponding waste may be supplied in a uniform state with separated shapes. For instance, when the waste is film, it may be supplied only as film without being mixed with other shapes; when the waste is trays, it may be supplied only as trays without being mixed with other shapes; and when the waste is textile, it may also be supplied only as textile without being mixed with other shapes. In this case, classification is relatively easy, and thus the waste is more likely to be classified by the waste classification device 220 such that it may be supplied to appropriate locations.

[0043] The waste classification device 220 may determine whether the information acquired from the waste is suitable for recycling treatment and specific chemical recycling treatment to support the closed-loop. For example, when determining that the corresponding waste is suitable for depolymerization treatment or glycolysis treatment, etc., the waste classification device 220 may classify the corresponding waste as a target for the closed-loop.

[0044] Here, when the waste is provided and distributed to the waste classification device 220, digital certification information corresponding to the corresponding waste may be provided and distributed together. In this case, the waste classification device 220 may acquire information on the corresponding waste and resource circulation tracking information from the corresponding digital certification information and may classify the corresponding waste as a target for the closed-loop based on the acquired information. For example, a token based on a blockchain platform may be used as the digital certification information. In this case, the corresponding waste may be classified as a target for the closed-loop based on the waste information and resource circulation tracking information acquired from the corresponding token (S401).

[0045] In addition, the waste classification device 220 may classify, among the waste, a target for the open-loop based on the information on the waste and the resource circulation tracking information. The success of the system for processing resource circulation depends on whether carbon emissions and cost may be reduced over the entire life cycle of the corresponding product, and when the waste is maximally classified as a resource circulation target or candidate material, the proportion of waste that is not recycled and is completely discarded is relatively reduced, thereby enabling the reduction of carbon emissions and cost. For example, when the corresponding waste is not suitable for a specific chemical recycling treatment (e.g., depolymerization treatment, glycolysis treatment, etc.), but is suitable for a chemical recycling treatment (e.g., pyrolysis, gasification, or solid refuse fuel (SRF) processing) other than the specific chemical recycling treatment, the waste classification device 220 may classify the waste as a resource circulation candidate material that allows resource circulation. Waste PE / PP / PS / ABS, which is highly contaminated to the level that it is difficult to recycle mechanically, may be classified as a candidate for pyrolysis, because pyrolysis oil may be produced through pyrolysis, and waste that may be decomposed into synthesis gas by applying high heat may be classified as a candidate suitable for gasification. Alternatively, waste that is advantageous for processing in solid form may also be classified as a candidate for solid refuse fuel (SRF) processing. Of course, pyrolysis, gasification, and SRF processing are merely examples of chemical recycling treatment and are not limited thereto (S402).

[0046] Subsequently, the waste classification device 220 may determine a preprocessing step including at least one of water washing treatment, chemical treatment, or physical treatment, for the target for the closed-loop and / or the target for the open-loop, based on the material properties of the corresponding waste. For example, the waste classification device 220 may determine the preprocessing step based on a comparison result between the content of heterogeneous components relative to the main components of the waste and a preset threshold value. For instance, when the content of heterogeneous components is equal to or greater than the preset threshold value, the preprocessing step may be determined to include solvent immersion, physical separation, chemical / physical separation, and the like for the corresponding waste. When the content of heterogeneous components is less than the preset threshold value, the preprocessing step may be determined not to include solvent immersion, physical separation, chemical / physical separation, and the like for the corresponding waste. The preprocessing process of the corresponding waste, based on the preprocessing step thus determined, may be performed by the waste classification device 220 or by separate preprocessing equipment interlocked with the waste classification device 220 (S403).

[0047] The threshold value used to determine the preprocessing step in step S403 may be a value preset so as to minimize carbon emissions and cost associated with the preprocessing and the chemical recycling treatment of step S404 that will be subsequently performed (e.g., depolymerization treatment, glycolysis treatment, etc.).

[0048] Meanwhile, although the above description describes an example in which the preprocessing process of step S403 is performed after the execution of step S401 and / or S402, the preprocessing process may be performed prior to step S401 and / or S402. Alternately, the classification process of step S401 and / or S402 may be divided into a primary classification before the preprocessing process and a secondary classification after the preprocessing process.

[0049] Next, the waste classification device 220 classifies, among the waste that has been classified as a target for the closed-loop in step S401 and then has undergone the preprocessing process of step S403, at least a portion thereof as a resource circulation material that may be processed into a chemical recycling raw material to be input into the production process of resource-circulated products. Here, classifying at least a portion as a resource circulation material may imply that, even after undergoing the preprocessing process of step S403, a portion of the waste may fail to meet the criteria for resource circulation material. Information on the resource circulation material thus classified may be provided to the product production device 230, or the corresponding resource circulation material may be provided to the product production device 230 so that material production and product production / processing may be performed through a specific chemical recycling treatment (e.g., depolymerization treatment, glycolysis treatment, etc.) (S404).

[0050] In addition, the waste classification device 220 may classify, among the waste that has been classified as a target for the open-loop in step S402 and then has undergone the preprocessing process of step S403, at least a portion thereof as a resource circulation candidate material that allows resource circulation through a chemical recycling treatment (e.g., pyrolysis, gasification, SRF processing, etc.) other than the specific chemical recycling treatment. Likewise, classifying at least a portion as a resource circulation candidate material may imply that, even after undergoing the preprocessing process of step S403, a portion of the waste may fail to meet the criteria for the resource circulation candidate material. The resource circulation candidate material thus classified may be transferred to a space for another chemical recycling treatment (e.g., pyrolysis, gasification, SRF processing, etc.) by a separate transport means, etc. For example, the resource circulation candidate material may be provided not to a first operator that performs material production and product production / processing through a specific chemical recycling treatment (e.g., depolymerization treatment, glycolysis treatment, etc.), but to a second operator that performs another chemical recycling treatment (e.g., pyrolysis, gasification, SRF processing, etc.) (S405).

[0051] As described above, according to an embodiment, waste is classified to be optimized for a closed-loop in which resource-circulated products are produced to be identical or similar to original waste through recycling treatment and specific chemical recycling treatment, so that at least a portion of the resource-circulated products is re-circulated as waste for recycling treatment. Accordingly, the total cost of resource circulation processing may be reduced by reducing the production cost of the resource-circulated products.

[0052] Further, by classifying resource circulation candidate materials from among waste classified as an open-loop, i.e., not forming a closed-loop, which allow resource circulation through chemical recycling treatment other than the specific chemical recycling treatment, it is possible to minimize disposal by external classification of the process and further reduce the total cost of resource circulation processing.

[0053] In addition, by generating, updating, and distributing digital certification information including information on the corresponding waste and resource circulation tracking information in response to the waste, there is an effect of facilitating the tracking of information on the waste and improving the ease and accuracy of waste classification.

[0054] Meanwhile, a computer program stored in a computer-readable storage medium may be implemented so as to include instructions for causing a processor to perform each step included in the method of providing solutions of a value chain for resource circulation according to the above-described embodiment.

[0055] In addition, the computer program including instructions for causing a processor to perform each step included in the method of providing solutions of a value chain for resource circulation according to the above-described embodiment may be recorded in a computer-readable storage medium.

[0056] Combinations of steps in each flowchart attached to the disclosure may be executed by computer program instructions. Since the computer program instructions can be mounted on a processor of a general-purpose computer, a special purpose computer, or other programmable data processing equipment, the instructions executed by the processor of the computer or other programmable data processing equipment create a means for performing the functions described in each step of the flowchart. The computer program instructions can also be stored on a computer-usable or computer-readable storage medium which can be directed to a computer or other programmable data processing equipment to implement a function in a specific manner. Accordingly, the instructions stored on the computer-usable or computer-readable storage medium can also produce an article of manufacture containing an instruction means which performs the functions described in each step of the flowchart. The computer program instructions can also be mounted on a computer or other programmable data processing equipment. Accordingly, a series of operational steps are performed on a computer or other programmable data processing equipment to create a computer-executable process, and it is also possible for instructions to perform a computer or other programmable data processing equipment to provide steps for performing the functions described in each step of the flowchart.

[0057] In addition, each step may represent a module, a segment, or a portion of codes which contains one or more executable instructions for executing the specified logical function(s). It should also be noted that in some alternative embodiments, the functions mentioned in the steps may occur out of order. For example, two steps illustrated in succession may in fact be performed substantially simultaneously, or the steps may sometimes be performed in a reverse order depending on the corresponding function.

[0058] The above description is merely exemplary description of the technical scope of the disclosure, and it will be understood by those skilled in the art that various changes and modifications can be made without departing from original characteristics of the disclosure. Examples of such various modifications and variations will now be described.

[0059] <First Modification Example>

[0060] Products such as multilayer structural layers consisting of at least one of adhesives or coating layers of acrylic, silicone, urethane, olefin, etc. which are included in release films, protective films, carrier films, trays, etc., used for electrical and electronic applications, may be consumed and discarded during an electrical and electronic production process, and may be provided to the waste classification device 220 through waste collection. The waste classification device 220 may perform a primary classification of target materials for the closed-loop among the materials of the waste and provide them to the product production device 230. For the coating materials, etc. other than target materials for the closed-loop present in the waste, the waste classification device 220 may compare the results of the component analysis of the foreign substances with a preset threshold value, perform a physical / chemical preprocessing process that are determined based on the comparison result, and provide target materials for the closed-loop reclassified through a secondary classification of the preprocessing result to the product production device 230.

[0061] <Second Modification Example>

[0062] Waste including a coating layer such as silicone included in automotive airbags collected from junkyards may be provided to the waste classification device 220. The waste classification device 220 may compare the analysis result of foreign substances for coating materials, etc. other than target materials for the closed-loop present in the waste with a preset threshold value, remove the foreign substances through a physical / chemical preprocessing process determined based on the comparison result, and provide target materials for the closed-loop reclassified through a secondary classification of the preprocessing result to the product production device 230.

[0063] <Third Modification Example>

[0064] Textile waste such as clothing and hygiene products that are discarded or collected from production processes in various industries may be provided to the waste classification device 220. The waste classification device 220 may determine an optimal preprocessing process based on the result of comparing the analysis result of foreign substances for materials other than target materials for the closed-loop present in the waste with a preset threshold value. For example, when textile materials other than polyester material, which is depolymerizable, are mixed at a ratio equal to or greater than a specific threshold value, a preprocessing process for chemically separating the polyester material from the other textile materials may be performed. Thereafter, the preprocessing result may be provided to the product production device 230, and the polyester material may be depolymerized by the product production device 230 and re-circulated in the form of a closed-loop.
