The decentralized identifier may be issued by a centralized or decentralized identity issuer. The decentralized identifier may be linked to authentication and/or authorization information. Access to the polyamide composition data can be controlled by the polyamide composition producer via the decentralized identifier and its unique association with the polyamide composition producer and the polyamide composition data (e.g., environmental attributes). This is in contrast to a centralized organization scheme in which identifiers are provided by such a centralized organization and access to data is controlled by such a centralized organization. In this context, decentralized refers to the use of the identifier being controlled by the data owner (such as the polyamide composition producer) at the time of implementation.

The dispersion identifier may be uniquely associated with the polyamide composition or with a physical entity of the polyamide composition, such as shipping to a consumer of the polyamide composition after packaging. The decentralized identifier may be unique to one or more environmental attributes. The polyamide composition pass or digital asset may include one or more digital representations that point to polyamide composition data that includes or point to a portion of the environmental attribute(s). The digital representation may include at least one interface to a data providing service. It may further comprise at least one interface to a data consumption service. It may comprise an endpoint for data exchange or sharing (resource endpoint) or an endpoint for service interaction (service endpoint), which is uniquely identified via a communication protocol. The digital representation(s) directed to the polyamide composition data or a portion thereof may be uniquely associated with the dispersion identifier.

The polyamide composition pass or digital asset may include or be connected to a digital representation of polyamide composition data, such as environmental attribute(s). The digital representation may include a representation for accessing polyamide composition data, such as environmental attribute(s) or a portion thereof. The digital representation may include a representation of polyamide composition data, such as environmental attribute(s). The polyamide composition pass or digital asset may include or be connected to data related to polyamide composition data such as environmental attribute(s), authentication information, and a distributed identifier. The data related to the polyamide composition data, such as the environmental attribute(s), may include a digital representation of the polyamide composition data, such as the environmental attribute(s).

Detailed Description

Fig. 1 illustrates an example of a chemical production network 102 that is combined with a production operating system 106 that includes an attribute management system to produce one or more output materials, particularly polyamide composition(s) 104, from one or more input materials 100.

To produce one or more output materials, particularly polyamide composition(s) 104, different input materials 100 may be provided as physical inputs to the chemical production network 102. The physical input material(s) 100 and the output material(s) (particularly the polyamide composition(s) 100, 104) may be associated with one or more characteristics related to environmental impact. The characteristics associated with the environmental impact may be digitized in the form of environmental attributes, such as the recycled content or biobased content of the input material. The production operating system 106 may be configured to acquire such environmental attributes and track them throughout the chemical production network 102 from the input material 100 to the output material(s), particularly the polyamide composition(s) 104.

The chemical production network 102 may include a plurality of interrelated processing steps. The chemical production network 102 may be an integrated chemical production network 102 having interconnected production chains. The chemical production network 102 may include a plurality of different production chains having at least one common intermediate product. The chemical production network 102 may include multiple stages of a chemical value chain. Chemical production network 102 may include production, refining, processing, and/or purification of gas or crude oil. The chemical production network 102 may include a steam cracker or a syngas facility that is connected to a plurality of production chains that output chemical products 104 from the effluent of such a facility. The chemical production network 102 may include a plurality of production chains that output one or more output materials, particularly polyamide composition(s), from one or more input materials 100. The chemical production network 102 may include a multi-layered chemical value chain. The chemical production network 102 may include an arrangement of production sites that are physically interconnected. The production sites may be located at the same location or at different locations. In the latter case, the production sites may be interconnected by a dedicated transportation system such as a pipeline, a supply chain vehicle (e.g., truck), a supply chain ship, or other cargo conveyance.

The chemical production network 102 may chemically convert the input material 100 into one or more output materials, particularly the polyamide composition(s) 104. The chemical production network 102 may convert the input material 100 into one or more output materials, particularly the polyamide composition(s) 104, by way of chemical conversion.

The input material 100 may be fed to the chemical production network 102 at any entry point. The input material 100 may be fed to the chemical production network 102 at the beginning of the chemical production network 102. For example, the input material 100 may constitute a feedstock for a steam cracker. The input material 100 may include non-fossil input materials (such as bio-based or recycled materials) and/or fossil input materials for use in the manufacture of chemical intermediate and chemical output material(s), particularly polyamide composition(s) 104.

The chemical production network 102 may include a plurality of production steps. The production steps included in the chemical production network 102 may be defined by system boundaries of the chemical production network 102. The system boundaries may be defined by the location or control of the production process. The system boundaries may be defined by the sites of the chemical production network 102. The system boundaries may be defined by a production process commonly controlled by an entity or entities. The system boundaries may be defined by a value chain with staggered production processes, which may be controlled separately by multiple entities, until the final product is formed. The chemical production network 102 may include waste collection and sorting steps, recovery steps (such as pyrolysis), cracking steps (such as steam cracking), separation steps for separating intermediates of one process step, and further processing steps for converting such intermediates into output material(s) (particularly polyamide composition(s) 104) that exit the system boundaries of the chemical production network 102.

The production operating system 106 of the chemical production network 102 may be configured to monitor and/or control the chemical production network 102 based on operating parameters of different processes. One process step monitored and/or controlled may be the feeding of the input material 100 or the release of the output material(s), particularly the polyamide composition(s) 104. Another process step that is monitored and/or controlled may be the registration of environmental attributes associated with the input material 100 entering the system boundary of the chemical production network 102. Yet another process step monitored and/or controlled may be to impart environmental properties to the output material(s) produced via the chemical production network, particularly the polyamide composition(s) 104. Yet another process step that is monitored and/or controlled may be the management of environmental properties associated with the input material 100 and the output material(s) (particularly the polyamide composition(s) 104) of the chemical production network 102.

Production operating system 106 may be configured to register inbound environment attributes and assign outbound environment attributes. The production operating system 106 may be configured to access data related to the input material 100, process, and/or output material(s) (particularly the polyamide composition(s) 104) of the chemical production network 102. For example, the production operating system 106 may be configured to register the recovered content or biobased content of one or more input materials 100 used in the chemical production network 102 as an environmental attribute. Production operating system 106 may be configured to assign environmental attributes to at least one balance account associated with the reclaimed content or biobased content of input material 100. The production operating system 106 may be configured to assign at least a portion of the environmental attributes from the at least one balance account to at least one output material, particularly the polyamide composition(s) 104.

The production operating system 102 may be configured to process environmental attributes associated with the input material(s) 100 and the output material(s) (particularly the polyamide composition(s) 100/104) of the chemical production network 102. For example, the production operating system 106 may be configured to determine environmental attributes associated with the use of the input material 100 that affect environmental characteristics of the chemical production network 102 and the output material(s) (particularly the polyamide composition(s) 104) produced by the chemical production network 102. Further, in particular, production operating system 102 may be configured to determine environmental properties associated with the output material(s), particularly polyamide composition(s) 104. As such, production operating system 102 may be configured to store environmental attributes in or extract environmental attributes from the balance account. Thus, environmental attributes may be considered credits that may be deposited into or deducted from an account associated with the input material and output material(s) (particularly polyamide composition (s)) of the chemical production network 102. In this way, environmental impact of production can be tracked and/or traced.

In chemical production network 102, multiple value chains may be linked. In addition, different input materials 100 or chemical processes that affect the environmental characteristics of the output material (particularly the polyamide composition(s) 104) produced by the chemical production network 102 may be used. Examples of such input materials 100 that affect at least one environmental characteristic of the output material(s) (particularly the polyamide composition(s) 104) produced from the input material 100 are recycled, renewable, or bio-based input materials 104. Examples of chemical processes that affect environmental characteristics include chemical processes that use environmentally friendly techniques such as carbon capture, carbon utilization, or heat pumps.

Due to the processing of chemicals in continuous or semi-continuous production and the complexity of the chemical production network 102, traceability of the input material throughout the network may be hindered. In this case, equivalent environmental attributes representing the impact on the environmental characteristics of the output material(s) (particularly the polyamide composition(s) 104) produced by the chemical production network may be assigned to the balance account 122 and assigned to the one or more output materials of the chemical production network 102, particularly the polyamide composition(s) 104. Thus, the environmental attribute may be decoupled from the physical material flow within the chemical production network 102. The decoupling may be based on a mass balance model, i.e. the equivalent weight assigned to one or more output materials, in particular the polyamide composition(s), cannot exceed the equivalent weight provided by the input material or process. If an equivalent has been assigned to a virtual account of one environmental attribute type, it may not be assigned again to another virtual account of this environmental attribute type. The environmental attribute types may be recycled, bio-based, renewable, and the like. The environmental attribute may be provided in the form of a digital asset attached to a physical entity of the polyamide composition or a polyamide composition pass.

Fig. 2 schematically illustrates an example of imparting environmental properties associated with an input material 100 to an output material(s) (particularly polyamide composition(s) 104) of a chemical production network 102.

As shown in FIG. 1, the chemical production network 102 and the operation of the chemical production network 102 may be monitored and/or controlled by the production operating system 106. The production operating system 106 may be configured to track environmental attributes from the input material 100 fed to the chemical production network 102 to the output material(s) (particularly the polyamide composition(s) 104) produced by the chemical production network 102. For tracking, the operating system 106 may be configured to register environmental attributes associated with the input material 100 provided to the chemical production network 102 and to impart the environmental attributes to the output material(s) produced by the chemical production network 102, particularly the polyamide composition(s) 104.

An input material 100, such as pyrolysis oil, bio-naphtha, or biogas, may be provided to a chemical production network 102. The input material 100 may enter a chemical production network 102, such as a steam cracker or syngas facility, at an entry point. The input material 100 may be used in a chemical production network 102 to produce one or more output materials, particularly polyamide composition(s) 104, from the input material 100. Output material(s), particularly polyamide composition(s) 104, may be provided at an exit point of chemical production network 102. Further output material(s) may be MDI, TDI, PA, EPS, PC, polyol, caprolactam, adipic acid, HMD, polyamide.

Upon entry of the input material 100, the input material data 108 may be provided to a computing interface of the production operating system 106 via a communication network. A data provider (such as a QR code reader) may be configured to provide material data 108 related to one or more input materials 100 and corresponding environmental attributes 108 to a computing interface configured to assign environmental attributes associated with the input materials 100. The material data 108 may include an input material identifier and environmental attributes associated with the input material 100. The input material identifier may be associated with a physical entity of the input material 100 entering the chemical production network 102. The material data may be provided at, before, or after the entry point provides one or more input materials to the chemical production network 102.

The input material identifier may be linked to the environmental attribute(s) associated with the respective input material(s) 100, the amount of input material 100, and a certificate certifying the environmental attribute(s). The amount of input material may be a measured amount of input material 100 fed to a facility or storage device of the chemical production network 102 for producing one or more output materials (particularly polyamide composition(s) 104) from the input material(s) 100. The input material identifiers associated with the respective input materials 100, the environmental attribute(s) associated with the respective input material(s) 100, and the amount of input material(s) 100 provided to the chemical production network 102 may be provided to the production operating system 106. Such data may be provided via a communication network upon entry into chemical production network 102 or may be communicated from a computing system to production operating system 106.

The inbound distributor 110 may be configured to distribute one or more environmental attributes to at least one balance account 112 associated with the respective environmental attribute. For example, one balance account 112 may relate to environmental attributes from recycled material, while another balance account 112 may relate to environmental attributes from bio-based material. The balance account may be associated with a corresponding environmental attribute type (such as bio-based or recycled 100). Based on such associations, a balance account associated with the environmental attribute type of the respective input material 100 may be selected. The environmental attribute may be assigned to the selected balance account. For example, an account 112 for reclaiming material may be selected and environmental attributes may be assigned to such an account 122.

To assign, one or more environmental attributes may be converted to balance units and these balance units may be assigned to balance account 122. The conversion may be based on conversion factors such as mass, weight, carbon atoms, hydrogen atoms, methane equivalent, or any other suitable measure for quantifying the environmental impact of environmental attributes. Thus, the conversion factor may take into account the difference between the production of a chemical product from a conventional input material(s) and the production of a chemical product from an unconventional input material(s) or the production of a chemical product from a mixture of conventional and unconventional input materials. The conversion factor may be related to differences in chemical and/or physical properties of the conventional and non-conventional input material(s).

By using the balance account 112, it can be ensured that the environmental properties of the input material 100 are only used to assign to the polyamide composition 104 once. This way, repeated counting of inputs or outputs is avoided to ensure that positive environmental effects can be reliably tracked and assigned to the polyamide composition 104.

The identifier provider 116 may be configured to provide a polyamide composition identifier associated with a polyamide composition produced by the chemical production network 102 and provided at an exit point of the chemical production network 102.

The outbound assigner 114 may be configured to assign at least one environmental attribute from the at least one balance account 112 associated with the respective environmental attribute to the polyamide composition identifier ID2. One or more environmental attributes may be assigned to the at least one polyamide composition identifier ID2. Assignment may include deallocating one or more environmental attributes from the balance account 112 associated with the corresponding environmental attribute type. The assignment may include converting one or more balance units to one or more environmental attributes.

Assigning at least one environmental attribute associated with the input material(s) to the polyamide composition(s) may include linking the polyamide composition identifier ID2 with the environmental attribute. The polyamide composition identifier ID2 may be associated with a physical entity of the polyamide composition. In this way, the virtual identifier of the material may be uniquely linked to the physical material. Such links may include physical or virtual links to identifiers uniquely associated with the physical material. For physical links, a label or code may be physically attached to the material, for example, by printing a QR code on the package. For virtual links, different identifiers associated with physical materials may be linked. For example, order numbers, LOT numbers, or combinations thereof may be linked.

The outbound assigner 114 may be configured to provide the environmental attribute associated with the polyamide composition to a data consumer, such as a system associated with a user of the polyamide composition. The outbound assigner 114 may be configured to provide environmental attributes associated with the polyamide composition to a decentralized network as will be described in the example of fig. 4. The environmental attribute may be provided in the form of a digital asset associated with a physical entity of the polyamide composition or a polyamide composition pass via the ID-based schema described above.

Fig. 3 schematically illustrates an example of imparting environmental properties of an input material 100 and a chemical process to a polyamide composition 104 produced by a chemical production network 102.

As described in the context of fig. 1 and 2, the chemical production network 102 and the operation of the chemical production network 102 may be monitored and/or controlled by the production operating system 106. An input material 100, such as pyrolysis oil, bio-naphtha, or biogas, may be provided to a chemical production network 102. The input material 100 may be used in a chemical production network 102 to produce one or more polyamide compositions 104 from the input material 100.

Upon entry of the input material 100, the input material data 108 may be provided to a computing interface of the production operating system 106 via a communication network. A data provider (such as a QR code reader) may be configured to provide material data 108 related to one or more input materials 100 and corresponding environmental attributes 108 to a computing interface configured to assign environmental attributes associated with the input materials 100. The material data 108 may include an input material identifier and environmental attributes associated with the input material 100. The input material identifier may be associated with a physical entity of the input material 100 entering the chemical production network 102. The input material identifier may be linked to a carbon footprint of the input material 100 as an environmental attribute. The material data may be provided at, before, or after the entry point provides one or more input materials to the chemical production network 102.

The inbound distributor 110 may be configured to retrieve one or more environmental attributes and provide such attributes to the Carbon Footprint (CF) generator 120. The process data provider 122 may be configured to collect process data associated with the chemical processing of the input material(s) 100 for producing the polyamide composition(s) 104. The process data provider 122 may be configured to collect energy data associated with energy consumption of the chemical process. The process data provider 122 may be configured to provide process data and energy data to the CF generator 120.

CF generator 120 may be configured to determine a carbon footprint of a polyamide composition produced by a chemical production network. The carbon footprint of the polyamide composition may be determined based on the process data, energy data, and carbon footprint of the input material(s) 100 used to produce the polyamide composition.

The outbound assigner 114 may be configured to assign the determined carbon footprint to the polyamide composition identifier ID2. One or more environmental attributes may be assigned to the at least one polyamide composition identifier ID2, as described in the context of fig. 2.

The outbound designator 114 may be configured to provide environmental attributes associated with the polyamide composition, particularly the carbon footprint, to a data consumer, such as a system associated with a user of the polyamide composition. The outbound assigner 114 may be configured to provide environmental attributes associated with the polyamide composition to a decentralized network as will be described in the example of fig. 4. The environmental attribute may be provided in the form of a digital asset associated with a physical entity of the polyamide composition or a polyamide composition pass via the ID-based schema described above.

Fig. 4 schematically illustrates an example of a method or apparatus for providing environmental properties associated with a polyamide composition to a user of a material as a data consumer via a decentralized network.

The polyamide composition 104 produced by the chemical production network 102 may be provided in association with a digital asset, as described in the context of fig. 2 and 3. The digital asset may include a polyamide composition identifier. The digital asset may include one or more environmental attributes such as product carbon footprint, recovery content, or biobased content. The digital asset may relate to one or more environmental attributes, such as product carbon footprint, recovery content, or biobased content. The digital asset may include a digital representation of one or more environmental attributes, such as product carbon footprint, recovery content, or biobased content.

The digital asset may further include or relate to authentication and/or authorization information linked to the polyamide composition identifier. Authentication and/or authorization information may be provided for authenticating and/or authorizing the data providing service 208 and/or the data consuming service 210. The polyamide composition identifier may include or relate to a dispersed identifier uniquely associated with the polyamide composition. The decentralized identifier may be connected to a digital representation of the environmental attribute. The digital representation may include a representation for accessing an environmental attribute or a portion thereof. The decentralized identifier may include a Universally Unique Identifier (UUID) or a Digital Identifier (DID). The distributed identifier may comprise any unique identifier uniquely associated with the data owner and/or the polyamide composition. The data owner may be the producer of the polyamide composition. Access to the material configuration data may be controlled by the data owner via the decentralized identifier and its unique association with the data owner and/or the polyamide composition.

Digital assets including a digital representation of one or more environmental attributes, such as product carbon footprint, recovery content, or biobased content, may be stored in the decentralized database 200. One or more environmental attributes, such as product carbon footprint, recovery content, or biobased content, may be stored in the database 202 associated with the owner of the data, such as the producer of the polyamide composition 104.

The polyamide composition 104 may be physically delivered to a user of the polyamide composition. The polyamide composition may be linked to a QR code that has encoded an identifier of the polyamide composition. A user of the polyamide composition may read the QR code through the QR code reader 206. The polyamide composition identifier may be provided to a database 208 associated with a consumer of the polyamide composition 104. In other embodiments, the consumer of the polyamide composition may retrieve the polyamide composition identifier through the decentralized database 200.

The data owners in this example may be input material producers, output material users, end product producers. The data owner may include any entity that generates data. The data generating node may be coupled to the data owner or to an entity that owns or produces a physical product from or for which data is generated. The data may be generated by a third party entity that is representative of an entity that owns the physical product from which or for which the data was generated.

The data consumption service 210 may include computer-executable instructions for accessing and/or processing data associated with a data owner, such as polyamide composition data. The data providing service 210 may include computer-executable instructions for providing and/or processing data (such as polyamide composition data) associated with a data owner for access and/or processing by the data consuming service 214.

Based on the received polyamide composition identifier, the data consumption service 210 may trigger a request for access to the environmental attribute associated with the polyamide composition identifier, as indicated by arrow 212. The polyamide composition identifier may be provided to a data providing service 214 associated with the producer of the polyamide composition 104 or the data providing service of the producer of the polyamide composition. In addition, authentication and/or authorization information may be provided.

The request may be authenticated and/or authorized to access the environmental attribute associated with the polyamide composition identifier. Based on successful authorization and/or authentication, access to the environmental properties associated with the polyamide composition identifier may be granted.

For access, the polyamide composition identifier may be provided to a data providing service 214, as indicated by arrow 212. The data providing service 214 may use the received polyamide composition identifier to retrieve the environmental properties associated with the polyamide composition 104, as indicated by arrows 218 and 220. Environmental attributes associated with the polyamide composition 104 provided to the data-providing service 214 may be provided to the data-consuming service 210, as indicated by arrow 216. The environmental attributes associated with the polyamide composition 104 may be stored in a database 208 associated with a user of the polyamide composition 104, as indicated by arrow 220.

By outputting an identifier or a dispersion identifier, the environmental attribute can be uniquely associated with the polyamide composition. Through the decentralized network, environmental properties can be transferred between the producer of the polyamide composition and the user of the polyamide composition. In this way, environmental attributes can be shared directly among the value chain participants through unique associations with the polyamide composition and without the need for a central intermediary. This achieves transparency of environmental attributes across the value chain and can track the positive environmental impact of the polyamide composition produced by the chemical production network 102 through the value chain.

Fig. 5 schematically illustrates an example of a method or apparatus for providing environmental properties associated with a polyamide composition across a value chain via a decentralized network.

In the example of fig. 6, a fully connected value chain comprising a chemical production network is schematically shown. In this example, the input material provider, polyamide composition producer, polyamide composition consumer, and end product producer may be connected to a decentralized network as described in the context of fig. 4. The environmental attributes may be provided in the form of digital asset or polyamide composition passes associated with the physical entities of the input material, polyamide composition, any intermediate product or end product via the ID-based schema described in the context of fig. 2-4.

The input material provider may provide an input material such as biogas or pyrolysis oil. The environmental properties of the input material may be provided by a data provision service connected to a decentralized network as described in the context of fig. 4. Polyamide composition producers can produce polyamide compositions from input material(s) provided to a chemical production network. The polyamide composition producer may access the environmental properties associated with the input material through a data consumption service connected to a decentralized network as described in the context of fig. 4. The polyamide composition producer may manage environmental attributes via a production operating system as described in the context of fig. 1-3. The polyamide composition producer may assign environmental attributes associated with the input material or environmental attributes associated with the chemical production network (such as carbon footprint) to the polyamide composition, as described in the context of fig. 1-3. The polyamide composition producer may provide environmental attributes associated with the polyamide composition through a data provision service connected to a decentralized network as described in the context of fig. 4. The polyamide composition user or end product producer can access the environmental properties associated with the polyamide composition through a data consumption service connected to a decentralized network as described in the context of fig. 4.

The corresponding data owners in this example may be input material producers, output material users, end product producers. The data owner may include any entity that generates data. The data generating node may be coupled to the data owner or to an entity that owns or produces a physical product from or for which data is generated. The data may be generated by a third party entity that is representative of an entity that owns the physical product from which or for which the data was generated.

The data consumption service may include computer-executable instructions for accessing and/or processing data associated with a data owner, such as polyamide composition data. The data providing service may include computer-executable instructions for providing and/or processing data (such as polyamide composition data) associated with the data owner for access and/or processing by the data consuming service.

In the example of fig. 5, the distributed identifier may be associated with the end product. Such a decentralized identifier may be provided to the value chain participant. Via the end product specific dispersed identifier, data associated with the end product produced from the polyamide composition can be collected across the production chain and assigned to the end product specific dispersed identifier. For example, the one or more environmental properties associated with the final product may be derived from the environmental property(s) associated with the polyamide composition, the input material, or any other product entity present in the value chain of the final product.

In this way, the environmental properties of the input material, the polyamide composition and any products produced from the polyamide composition can be tracked through the value chain to the final product. By tracking environmental properties of materials in this manner, information can be made transparent throughout the value chain, while information flow can be controlled by participants in the supply chain. In addition, the production operating system as described in the context of fig. 1 and 3 may process environmental attributes as desired by the individual participants. In general, such tracking enables tracking of the active environmental impact of individual supply chain participants, which makes the active environmental impact transparent and can be imparted to individual supply chain participants.

Fig. 6 schematically illustrates an example of a chemical production network for producing a polyamide composition 618 associated with a composition pass or digital asset. The example of fig. 6 is an illustrative example and should not be considered limiting.

In the example of fig. 6, fossil feedstock, biological feedstock, and recycled feedstock may be provided to a chemical production network (see, e.g., fig. 1-5) for producing, e.g., polyamide 6 polymer 616. Polyamide 6 polymer 616 is one example of a polyamide composition that may be part of or may be formed from polyamide composition 618.

The chemical production network 202 may include a syngas facility and a steam cracker. Mixed feeds may be fed to the syngas facility, including fossil feeds, biological feeds, and recycled feeds. The biological feedstock may include biological methane, biological naphtha, or mixtures thereof. The recycled raw material may include pyrolysis oil, such as pyrolysis oil produced from scrap tires. The fossil feedstock may include natural gas and/or naphtha produced from crude oil. The steam cracker may be fed with fossil feedstock, biological feedstock and recycled feedstock. The recycled raw material may include, for example, pyrolysis oil produced from mixed plastic waste. The biological feedstock may include bio-naphtha, bio-diesel, or a mixture thereof. The steam cracker may be fed with a mixed feedstock, such as a synthesis gas plant. The steam cracker may be fed by products produced from a synthesis gas plant and vice versa.

Ammonia, nitric acid, hydroxylamine and other intermediate materials may be produced from fossil raw materials, biological raw materials and recycled raw materials (see C ₁ value chain 620). Caprolactam 614 and other materials, such as intermediate or export materials, may be produced from nitric acid, hydroxylamine and other intermediates. Benzene 608, cyclohexane 610, and other C ₃ and C ₄ intermediates (see C ₆ value chain 622) can be produced from fossil feedstocks, biological feedstocks, and recycled feedstocks. Intermediate products from C ₆ value chain 622, such as p-propenone (anolone) 612, may be combined with intermediate products from C ₁ value chain 620 to produce other intermediate products, such as caprolactam 614. Different polyamide polymers 616, such as those listed above, may be produced from caprolactam 614.

In addition, the biobased or recovered intermediate may enter the production network in an intermediate step. For example, benzene produced from bio-based or recycled raw materials may be used instead of benzene as shown in fig. 6.

In the example of fig. 6, the biomethane content of biomethane and/or the pyrolysis oil content of pyrolysis oil as non-fossil input materials may be tracked. As described in the context of fig. 2, the biomethane content and/or pyrolysis oil content at the start of the production chain of the polyamide composition 618 (such as polyamide 6 616) may be registered via the operating system 108. Here, pyrolysis oil content may be assigned to balance account 210 associated with metadata (such as metadata indicating that the balance account is assigned to recycled material). The biomethane content may be assigned to the balance account 212 associated with metadata (such as metadata indicating that the balance account is assigned to the biobased material). Thus, the environmental attributes of the biomethane content and/or pyrolysis oil content are separated from the mass flow of the chemical processes in the chemical production network 202, as shown in fig. 6.

To impart a biomethane content and/or a pyrolysis oil content for producing a polyamide composition, such as a polyamide composition comprising polyamide 6 616, the biomethane content and/or the pyrolysis oil content may be determined. The biomethane content and/or pyrolysis oil content that can be imparted to the production of the polyamide composition can be based on conservation of mass that can be imparted to the produced polyamide composition. For example, only half of the biomethane content and/or pyrolysis oil content may be imparted to the polyamide composition, while the other half may be imparted to other output products produced from the mixed feedstock as input material. Environmental attributes of the biomethane content and/or pyrolysis oil content may be imparted to the polyamide composition in such proportions.

Registering the biomethane content and/or pyrolysis oil content of the input material and imparting the registered environmental attributes to the produced polyamide composition 618 may be performed as described with respect to fig. 2. In the system shown in fig. 2, by associating a dispersed ID with a polyamide composition and assigning an environmental attribute to the dispersed ID, the environmental attribute associated with the production of polyamide composition 618 can be imparted to the produced polyamide composition. By linking the ID and the environmental attribute, the environmental attribute can be uniquely linked to the polyamide composition produced. The polyamide composition may be delivered to a consumer of the polyamide composition, such as a producer of other products produced using the received polyamide composition. The package (e.g., bag) containing the polyamide composition may include a QR code. The decentralized ID may be included or encoded into the QR code. In this way, a consumer of the polyamide composition may access the environmental properties associated with the polyamide composition via an ID-based protocol as described in the context of fig. 4 and 5.

Similarly to this example, registering carbon footprint data associated with the input materials and production process and assigning the carbon footprint to the polyamide composition may be based on the method illustrated in fig. 3 for the carbon footprint.
