Environmental attributes may include environmental features, technical features, recyclability features, or circularity features associated with the environmental impact of input materials, chemical processes, chemical production networks, and / or olefin compositions.

[0053] Environmental attributes may include one or more characteristics attributable to the environmental impact of input materials, chemical processes, chemical production networks, and / or olefin compositions. Environmental attributes may include environmental features, technical features, recyclability features, or circulation features associated with the environmental impact of input materials, chemical processes, chemical production networks, and / or olefin compositions. One or more environmental attributes may be attributable to the environmental impact of the olefin composition. One or more environmental attributes may be associated with the environmental features, technical features, recyclability features, circulation features, and / or complementary risk features of the olefin composition.

[0054] Environmental characteristics can identify or quantify ecological criteria associated with environmental impacts. Environmental characteristics may be or derive from measurements obtained during the life cycle. Environmental characteristics may be determined at any stage of the life cycle, but can characterize the environmental impacts at or up to such a stage. Environmental characteristics may include, for example, carbon footprint, greenhouse gas emissions, resource use, air emissions, ozone depletion potential, water pollution, noise pollution, energy consumption, waste reduction, or eutrophication potential. Environmental characteristics may also include, for example, product characteristics related to the production of products such as bio-based, plant-based, animal-based, halogen-free, fluorine-free, vegan, halal, kosher, palm oil-free, natural, tox-fee-free, volatile organic compound-free, or any combination thereof.

[0055] Technical features can identify or quantify product performance that is at least indirectly associated with environmental impact. Technical features may be measurements obtained during the lifecycle, or may be derived from such measurements. Technical features may be determined at any stage of the lifecycle, but may characterize performance at or up to such a stage. Technical features may include, for example, chemical composition data, raw material composition, bio-based or recycled input material contents specifying, for example, x% non-fossil contents and y% fossil contents, bills of materials, product specification data, for example, product purity, product form (as an indicator of impact on dust formation / release), safety data, product extractability, migration data, toxicity data or ecotoxicity data, product component data, safety data, application characteristics data, application instructions, quality data, or any combination thereof.

Circulation features may be determined at any stage of the lifecycle, characterizing reuse or regeneration performance at or up to such a stage. Circulation features may include, for example, regeneration data, reuse rate, regeneration rate, regeneration loop, reuse performance, reuse quality, or any combination thereof.

[0057] Recyclability features can identify or quantify lifecycle features associated with recycling. Recyclability features may include the composition of a material containing specially formulated components that produce a material suitable for recycling. Recyclability features may be measurements obtained during the lifecycle, or may be derived from such measurements. Recyclability features may be recycling data recorded in one or more past lifecycles, or may be derived from such data. Recyclability features may be determined at any stage of the lifecycle, characterizing recycling performance at or up to such a stage. Recyclability features may include, for example, recycling data, reuse count, recyclate composition, recyclate quality, waste flow composition, waste flow quality, or any combination thereof.

[0058] In one embodiment, an olefin composition passport or digital asset associated with an olefin composition may include mass-balanced environmental attributes related to the input materials. These mass-balanced environmental attributes may include environmental attributes of the input materials used to produce the olefin composition, tracked by the mass attributable to the olefin composition. The environmental impact of the input materials may be determined based on the input materials used in the chemical process producing the olefin composition. For example, the bio-based, renewable, and / or recycled contents of the input materials used to produce the olefin composition may be tracked. Furthermore, for example, the castor oil or palm oil contents of the input materials used to produce the olefin composition may be tracked. Further, for example, properties related to the environmental impact of the input materials may include RSPO palm oil, palm oil-free, and castor oil, and these properties may be tracked. Even further, for example, the properties of the chemical process used to produce the olefin composition may be tracked. Examples of tracked process characteristics related to environmental impact include water consumption, CO2 emissions and / or greenhouse gas (GHG) emissions, waste generation, mixed material generation, recycling design, energy consumption, and treatment characteristics, such as waste reduction or reduction of characteristic loss. These characteristics may be tracked based on certification from an accreditation body. These characteristics may also be tracked based on inherent physical characteristics derived from measurements.

[0059] In one embodiment, the produced olefin composition is linked to a decentralized identifier that physically identifies the produced olefin composition. The production control device may be configured to provide a decentralized identifier associated with the physical entity of the produced olefin composition. The production control device may be configured to associate the decentralized identifier with the physical identifier of the produced olefin composition. The production control device may be configured to assign the decentralized identifier to a physical identifier linked to the produced olefin composition. The production control device may be configured to assign the decentralized identifier to a physical identifier physically linked to the produced olefin composition.

[0060] In one embodiment, a decentralized identifier may relate to data associated with at least one product produced from an olefin composition, and one or more environmental attributes associated with at least one product may derive from one or more environmental attributes associated with the olefin composition. One or more environmental attributes associated with the olefin composition may be associated with one or more input materials and / or chemical processes used to produce the olefin composition. A decentralized identifier may relate to any identifier uniquely associated with the olefin composition. A decentralized identifier may be associated with a physical entity of the olefin composition. A decentralized identifier may refer to a single batch of the olefin composition. A decentralized identifier may be associated with a group of olefin compositions. This identifier may refer to multiple physical entities of the olefin composition. A decentralized identifier may be associated with a continuous or semi-continuous flow of the olefin composition. This identifier may refer, for example, to a flow of the olefin composition over a particular period of time or from a particular source.

[0061] In one embodiment, one or more environmental attributes associated with an olefin composition are provided from at least one balancing account configured to store environmental attributes associated with an input material. The balancing account may be associated with metadata, such as a storage structure associated with an environmental attribute type. For example, the balancing account may be associated with metadata indicating that the environmental attribute type is a recycled content or a biosystem. An inbound allocator may be configured to assign one or more environmental attributes associated with an input material to at least one balancing account when, for example, an input material enters a chemical production network. The balancing account may be associated with a corresponding environmental attribute type. An outbound assigner may be configured to assign at least one environmental attribute from at least one balancing account associated with a corresponding environmental attribute to a decentralized identifier. At least one decentralized identifier may be assigned one or more environmental attributes. The assignment may include deassigning one or more environmental attributes from the balancing account associated with the corresponding environmental attribute type. The use of balancing accounts ensures that the environmental attributes of the input material are reliably tracked and assigned to the olefin composition.

[0062] In one embodiment, one or more environmental attributes associated with an olefin composition are provided from at least one equilibration account configured to store environmental attributes associated with input materials. An inbound allocator may be configured to assign one or more environmental attributes to at least one equilibration account associated with corresponding environmental attributes when, for example, input materials enter the chemical production network. The equilibration account may be associated with corresponding environmental attribute types. One or more environmental attributes associated with input materials may be assigned to an equilibration account associated with corresponding environmental attribute types. An outbound assigner may be configured to assign or associate at least one environmental attribute from at least one equilibration account associated with corresponding environmental attribute types to a decentralized identifier. This may include deassigning one or more environmental attributes from the equilibration account associated with corresponding environmental attribute types. The use of equilibration accounts allows environmental attributes to be tracked by the chemical production network. In this way, environmental attributes can be decoupled from the material flow. The attribution of environmental attributes may be based on the mass balance of the chemical production network. In this method, the total mass of the input material and the olefin composition, as well as the attribution of corresponding environmental attributes associated with the input material and the olefin composition, are equilibrated.

[0063] In one embodiment, one or more environmental attributes are associated with at least one characteristic relating to the environmental impact of one or more input materials and / or chemical processes. One or more environmental attributes may identify the environmental characteristics of the input materials used to produce the olefin composition, and / or identify the environmental characteristics of the chemical processes used to produce the olefin composition. One or more environmental attributes may be generated from the environmental characteristics of the input materials used to produce the olefin composition, process data associated with the chemical treatment of the input materials, and / or energy data associated with the energy consumption of the chemical treatment. One or more environmental attributes may include recycled content associated with the input materials and that can be allocated to or assigned to the olefin composition, renewable content associated with the input materials and that can be allocated to or assigned to the olefin composition, and / or the product carbon footprint associated with the olefin composition.

[0064] In one embodiment, the production operation device is configured to collect environmental attributes associated with the produced olefin composition before, during, and / or after production of the olefin composition by the chemical production network. The environmental attributes associated with the produced olefin composition may be related to the input material. The environmental attributes associated with the input material may be provided before, during, and / or after production of the olefin composition by the chemical production network. The environmental attributes associated with the input material may be assigned to at least one equilibration account before, during, and / or after production of the olefin composition by the chemical production network. The environmental attributes associated with the produced olefin composition may be related to environmental characteristics generated from process data associated with the chemical treatment of the input material and / or energy data associated with the energy consumption of the chemical treatment. The environmental attributes associated with the produced olefin composition may be generated before, during, and / or after production of the olefin composition by the chemical production network. Process data associated with the chemical treatment of the input material and / or energy data associated with the energy consumption of the chemical treatment may be collected before, during, and / or after production of the olefin composition.

[0065] In one embodiment, an olefin composition passport or digital asset may include a decentralized identifier associated with an olefin composition, and one or more environmental attributes associated with the decentralized identifier. One or more environmental attributes may be associated with a decentralized identifier contained in the olefin composition passport or digital asset. One or more environmental attributes may be stored in a database associated with an olefin composition producer, or in the olefin composition producer's database, for access by any olefin composition consumer. One or more environmental attributes may be stored in a database associated with an olefin composition producer, or in the olefin composition producer's database, for transfer to the olefin composition consumer, for example, when the olefin composition is accessed or provided. The decentralized identifier may include any unique identifier uniquely associated with the olefin composition producer and olefin composition data, such as environmental attributes. The decentralized identifier may include a Universally Unique Identifier (UUID) or a Digital Identifier (DID). The decentralized identifier may be issued by a centralized or decentralized identity issuer. Decentralized identifiers may be associated with authentication and / or authorization information. Through a unique association of the decentralized identifier with the olefin composition producer and the olefin composition data, such as environmental attributes, access to the olefin composition data may be controlled by the olefin composition producer. This is in contrast to a centralized system where identifiers are provided by such a central authority and access to the data is controlled by such a central authority. In this context, decentralized refers to the use of identifiers in implementations controlled by the data owner, such as the olefin composition producer.

[0066] A decentralized identifier may be uniquely associated with an olefin composition or a physical entity of an olefin composition, for example, packaged for transport to an olefin composition consumer. The decentralized identifier may be unique to one or more environmental attributes. An olefin composition passport or digital asset may include one or more digital representations pointing to olefin composition data containing environmental attributes, or portions thereof containing environmental attributes. A digital representation may include at least one interface to data delivery services. This may further include at least one interface to data consumption services. This may include endpoints for data exchange or sharing (resource endpoints) or endpoints for service interaction (service endpoints) uniquely identified via a communication protocol. A digital representation pointing to olefin composition data or portions thereof may be uniquely associated with a decentralized identifier.

[0067] An olefin composition passport or digital asset may include, or be linked to, a digital representation of olefin composition data, such as environmental attributes. The digital representation may include a representation for accessing olefin composition data, such as environmental attributes or parts thereof. The digital representation may include a representation of olefin composition data, such as environmental attributes. An olefin composition passport or digital asset may include, or be linked to, olefin composition data, such as data related to environmental attributes, authentication information, and decentralized identifiers. The data related to olefin composition data, such as environmental attributes, may include a digital representation of olefin composition data, such as environmental attributes.

[Modes for carrying out the invention]

[0070] Figure 1 shows an example of a chemical production network that produces one or more output materials, specifically olefin compositions 104, from one or more input materials 100, in relation to a production operation system 106 that includes an attribute management system.

[0071] Different input materials 100 may be provided as physical inputs to the chemical production network 102 in order to produce one or more output materials, specifically olefin compositions 104. The physical input materials 100 and the output materials, specifically olefin compositions 104, may be associated with one or more properties related to environmental impact. Properties related to environmental impact may be digitized in the form of environmental attributes, such as the regeneration of input materials or bio-based contents. The production operation system 106 may be configured to take in such environmental attributes and track them across the chemical production network 102 from the input materials 100 to the output materials, specifically olefin compositions 104.

[0072] The chemical production network 102 may include a plurality of interconnected processing steps. The chemical production network 102 may be an integrated chemical production network 102 that includes interconnected production chains. The chemical production network 102 may include a plurality of different production chains that have at least one intermediate product in common. The chemical production network 102 may include a plurality of stages in the chemical value chain. The chemical production network 102 may include the production, refining, processing, and / or purification of gas or crude oil. The chemical production network 102 may include a synthesis gas plant connected to a plurality of production chains that output product 104 from a stream cracker or synthesis gas plant effluent. The chemical production network 102 may include a plurality of production chains that output one or more output materials, specifically olefin compositions 104, from one or more input materials 100. The chemical production network 102 may include a plurality of hierarchies in the chemical value chain. The chemical production network 102 may include a physically interconnected arrangement of production sites. Production sites may be located in the same place or in different locations. In the latter case, production sites may be interconnected by dedicated transportation systems, such as pipelines, supply chain vehicles like trucks, supply chain ships, or other means of freight transport.

[0073] The chemical production network 102 can chemically convert the input material 100 into one or more output materials, specifically olefin compositions 104.

[0074] The input material 100 may be supplied to the chemical production network 102 at any inlet point. The input material 100 may be supplied to the chemical production network 102 at the start of the chemical production network 102. The input material 100 may, for example, constitute the raw materials 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 producing chemical intermediates and chemical output materials, specifically olefin composition 104.

[0075] The chemical production network 102 may include multiple production steps. The production steps included in the chemical production network 102 may be defined by the system boundary of the chemical production network 102. The system boundary may be defined by location or control over the production process. The system boundary may be defined by the site of the chemical production network 102. The system boundary may be defined by a production process controlled by one entity or jointly by multiple entities. The system boundary may be defined by a value chain having alternating production processes to a final product, which may be controlled separately by multiple entities. The chemical production network 102 may include a waste collection and sorting step, a recycling step, e.g., pyrolysis, a cracking step, e.g., steam cracking, a separation step for separating intermediates of one process step, and further processing steps for converting such intermediates into output materials, specifically olefin compositions 104 that exit the system boundary of the chemical production network 102.

[0076] The production operation system 106 of the chemical production network 102 may be configured to monitor and / or control the chemical production network 102 based on different process operation parameters. One process step to be monitored and / or controlled may be the supply of input material 100 or the release of output material, specifically olefin composition 104. Another process step to be 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 to be monitored and / or controlled may be the attribution of environmental attributes to output material, specifically olefin composition 104, produced through the chemical production network 102. Yet another process step to be monitored and / or controlled may be the management of environmental attributes associated with the input material 100 and output material, specifically olefin composition 104, of the chemical production network 102.

[0077] The production operation system 106 may be configured to register inbound environmental attributes and assign outbound environmental attributes. The production operation system 106 may be configured to access data related to input materials 100, processes, and / or output materials, specifically olefin compositions 104, used in the chemical production network 102. For example, the production operation system 106 may be configured to register the regenerated or bio-based contents of one or more input materials 100 used in the chemical production network 102 as environmental attributes. The production operation system 106 may be configured to assign environmental attributes to at least one equilibration account associated with the regenerated or bio-based contents of the input materials 100. The production operation system 106 may be configured to assign at least a portion of the environmental attributes from at least one equilibration account to at least one output material, specifically olefin compositions 104.

[0078] The production operation system 102 may be configured to handle environmental attributes related to the input materials 100 and output materials, specifically olefin compositions 104, of the chemical production network 102. For example, the production operation system 106 may be configured to determine environmental attributes associated with the use of input materials 100 that affect the environmental properties of the chemical production network 102, and output materials, specifically olefin compositions 104, produced by the chemical production network 102. More specifically, the production operation system 102 may be configured to determine environmental attributes associated with output materials, specifically olefin compositions 104. In this way, the production operation system 102 may be configured to store environmental attributes in an equilibration account or to retrieve environmental attributes from an equilibration account. Thus, environmental attributes can be considered as credits that can be deposited into or withdrawn from accounts related to the input materials and output materials, specifically olefin compositions, of the chemical production network 102. In this way, the environmental impact of production can be tracked and / or followed.

[0079] Multiple value chains may be interconnected within the chemical production network 102. Furthermore, various input materials 100 or chemical processes may be used that affect the environmental properties of the output material produced by the chemical production network 102, specifically the olefin composition 104. An example of an input material 100 that affects at least one environmental property of the output material produced from such input material 100, specifically the olefin composition 104, is a recycled, renewable, or bio-based input material 104. Examples of chemical processes that affect environmental properties include environmentally friendly technologies, such as chemical processes using carbon capture, carbon utilization, or heat pumps.

[0080] Due to the processing of chemicals in continuous or semi-continuous production, and the complexity of the chemical production network 102, traceability of input materials through this network may be hindered. In such scenarios, equivalent environmental attributes indicating the impact on the environmental properties of the output material produced by the chemical production network, specifically the olefin composition 104, may be assigned to an equilibration account and then assigned to one or more output materials of the chemical production network 102, specifically the olefin composition 104. Thus, environmental attributes may be separated from the physical flow of materials within the chemical production network 102. The separation may also be based on a mass balance model, in that the equivalents assigned to one or more output materials, specifically the olefin composition, may not exceed the equivalents provided by the input material or process. If equivalents are assigned to a virtual account of one environmental attribute type, a second assignment to another virtual account of the same environmental attribute type should not be made. Environmental attribute types may include recycled, bio-based, renewable, etc. Environmental attributes may be provided in the form of a digital asset attached to the physical entity of the olefin composition or in the form of an olefin composition passport.

[0081] Figure 2 schematically illustrates an example of attributing environmental attributes associated with input material 100 to output material of chemical production network 102, specifically olefin composition 104.

[0082] As shown in Figure 1, the chemical production network 102 and its operation may be monitored and / or controlled by a production operation system 106. The production operation system 106 may be configured to track environmental attributes from input materials 100 supplied to the chemical production network 102 to output materials produced by the chemical production network 102, specifically olefin compositions 104. For tracking purposes, the production operation system 106 may be configured to register environmental attributes associated with the input materials 100 provided to the chemical production network 102 and to attribute these environmental attributes to the output materials produced by the chemical production network 102, specifically olefin compositions 104.

[0083] The input material 100, for example, pyrolysis oil, bionaphtha, or biogas, may be supplied to the chemical production network 102. The input material 100 may also enter the chemical production network 104 at an inlet point, for example, a steam cracker or a synthesis gas plant. By being used within the chemical production network 102, the input material 100 may produce one or more output materials, specifically olefin compositions 104. The output materials, specifically olefin compositions 104, may be supplied to an outlet point of the chemical production network 102. Further output materials may be MDI, TDI, PA6, EPS, PC, polyols, caprolactam, adipic acid, HMD, or polyamides.

[0084] When input material 100 is received, input material data 108 may be provided to the computing interface of the production operation system 106 via a communication network. A data provider, such as a QR code® reader, may be configured to provide material data 108 associated with one or more input materials 100 and corresponding environmental attributes 108 to the computing interface, which is 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 the physical entity of the input material 100 entering the chemical production network 102. The material data may be provided at the time of, before, or after the provision of one or more input materials at the entry point leading to the chemical production network 102.

[0085] The input material identifier may be associated with the corresponding input material 100, its associated environmental attributes, the quantity of the input material 100, and a certificate proving the environmental attributes. The quantity of the input material may be the measured amount of the input material 100 supplied to the plant or storage unit of the chemical production network 102 for producing one or more output materials, specifically olefin compositions 104, from the input material 100. The input material identifier associated with the corresponding input material 100, the associated environmental attributes, and the quantity of the input material 100 supplied to the chemical production network 102 may be provided to the production operation system 106. Such data may be provided via a communication network upon entry into the chemical production network 102, or it may be transferred from a computing system to the production operation system 106.

[0086] The inbound allocator 110 may be configured to assign one or more environmental attributes to at least one equilibration account 112 associated with the corresponding environmental attribute. For example, one equilibration account 112 may be associated with environmental attributes from recycled materials, while the other equilibration account 112 may be associated with environmental attributes from bio-based materials. The equilibration account may be associated with the corresponding environmental attribute type, for example, bio-based or recycled. Based on such associations, an equilibration account associated with the corresponding input material 100 environmental attribute type may be selected. The environmental attribute may be assigned to the selected equilibration account. For example, an account 112 for recycled materials may be selected, and the environmental attribute may be assigned to such an account 122.

[0087] For allocation purposes, one or more environmental attributes may be converted into equilibration units, which may then be assigned to equilibration account 122. The conversion may also be based on a conversion factor, e.g., mass, weight, carbon atoms, hydrogen atoms, methane equivalent, or any other preferred measure for quantifying the environmental impact of the environmental attribute. Thus, the conversion factor may take into account the difference between producing a chemical product from conventional input materials and producing a chemical product from non-conventional input materials, or producing a chemical product from a mixture of conventional and non-conventional input materials. The conversion factor may relate to the difference in the chemical and / or physical properties of the conventional and non-conventional input materials.

[0088] The use of the equilibration account 112 ensures that the environmental attributes of the input material 100 are used only once for assignment to the olefin composition 104. In this way, double counting of inputs or outputs is avoided, ensuring that positive environmental impacts are reliably tracked and assigned to the olefin composition 104.

[0089] The identifier provider 116 may be configured to provide olefin composition identifiers associated with olefin compositions produced by and supplied at the exit points from the chemical production network 102.

[0090] The outbound assigner 114 may be configured to assign at least one environmental attribute from at least one equilibration account 112 associated with a corresponding environmental attribute to the olefin composition identifier ID2. At least one olefin composition identifier ID2 may be assigned one or more environmental attributes. The assignment may include deassigning one or more environmental attributes from the equilibration account 112 associated with a corresponding environmental attribute type. The assignment may include converting one or more equilibration units to one or more environmental attributes.

[0091] Assigning at least one environmental attribute associated with the input material to the olefin composition may include associating the olefin composition identifier ID2 with the environmental attribute. The olefin composition identifier ID2 may be associated with the physical entity of the olefin composition. In this way, the virtual identifier of the material may be uniquely associated with the physical material. Such associations may include physical or virtual links of identifiers uniquely associated with the physical material. In a physical association, for example, a tag or code may be physically attached to the material by printing a QR code (registered trademark) on the package. In a virtual association, various identifiers associated with the physical material may be associated. For example, an order number, batch number, lot number, or a combination thereof may be associated.

[0092] The outbound signer 114 may be configured to provide environmental attributes associated with the olefin composition to data consumers, for example, systems associated with users of the olefin composition. The outbound signer 114 may be configured to provide environmental attributes associated with the olefin composition to a decentralized network, as illustrated in the example in Figure 4. The environmental attributes may be provided in the form of digital assets associated with the physical entity of the olefin composition or an olefin composition passport via the ID-based schema described above.

[0093] Figure 3 schematically illustrates an example of attributing the environmental attributes of the input material 100 and the chemical process to the olefin composition 104 of the chemical production network 102.

[0094] As described in the context of Figures 1 and 2, the chemical production network 102 and its operation may be monitored and / or controlled by the production operation system 106. Input materials 100, such as pyrolysis oil, bionaphtha, or biogas, may be supplied to the chemical production network 102. The input materials 100 may be used in the chemical production network 102 to produce one or more olefin compositions 104 from the input materials 100.

[0095] When input material 100 is received, input material data 108 may be provided to the computing interface of the production operation system 106 via a communication network. A data provider, such as a QR code® reader, may be configured to provide material data 108 associated with one or more input materials 100 and corresponding environmental attributes 108 to the computing interface, which is 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 the physical entity of the input material 100 entering the chemical production network 102. The input material identifier may be associated with the carbon footprint of the input material 100 as an environmental attribute. The material data may be provided at the time of, before, or after the provision of one or more input materials at the entry point leading to the chemical production network 102.

[0096] The inbound allocator 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 treatment of the input material 100 to produce the olefin composition 104. The process data provider 122 may be configured to collect energy data associated with the energy consumption of the chemical treatment. The process data provider 122 may be configured to provide the process data and energy data to the CF generator 120.

[0097] The CF generator 120 may be configured to determine the carbon footprint of an olefin composition produced by a chemical production network. The carbon footprint of the olefin composition may be determined based on process data, energy data, and carbon footprint of the input material 100 used to produce the olefin composition.

[0098] The identifier provider 116 may be configured to provide olefin composition identifiers associated with olefin compositions produced by and supplied at the exit points from the chemical production network 102.

[0099] The outbound assignor 114 may be configured to assign the determined carbon footprint to an olefin composition identifier ID2. At least one olefin composition identifier ID2, for example, as shown in the context of Figure 2, may be assigned one or more environmental attributes.

[0100] The outbound assigner 114 may be configured to provide data consumers, for example, systems associated with users of olefin compositions, with environmental attributes, specifically carbon footprints, associated with the olefin composition. The outbound assigner 114 may be configured to provide environmental attributes associated with the olefin composition to a decentralized network, as illustrated in the example in Figure 4. The environmental attributes may be provided in the form of digital assets associated with the physical entity of the olefin composition or an olefin composition passport via the ID-based schema described above.

[0101] Figure 4 schematically illustrates an example of a method or apparatus for providing environmental attributes associated with olefin compositions to material users as data consumers via a decentralized network.

[0102] The olefin composition 104 produced by the chemical production network 102 may be provided in association with digital assets described in the context of Figures 2 and 3. The digital assets may include an olefin composition identifier. The digital assets may include one or more environmental attributes, e.g., the product's carbon footprint, recycled content, or bio-based content. The digital assets may be associated with one or more environmental attributes, e.g., the product's carbon footprint, recycled content, or bio-based content. The digital assets may include digital representations of one or more environmental attributes, e.g., the product's carbon footprint, recycled content, or bio-based content.

[0103] The digital asset may further include, or may be associated with, authentication and / or authorization information linked to the olefin composition identifier. Authentication and / or authorization information may be provided for authentication and / or authorization of data provision service 208 and / or data consumption service 210. The olefin composition identifier may include, or may be associated with, a decentralized identifier uniquely associated with the olefin composition. The decentralized identifier may be linked to a digital representation of environmental attributes. The digital representation may include a representation for accessing the environmental attributes or parts thereof. The decentralized identifier may include a universally unique identifier (UUID) or a digital identifier (DID). The decentralized identifier may include any unique identifier uniquely associated with the data owner and / or the olefin composition. The data owner may be the producer of the olefin composition. Access to the material composition data may be controlled by the data owner through the decentralized identifier and its unique association with the data owner and / or the olefin composition.

[0104] Digital assets, including one or more environmental attributes such as the carbon footprint of a product, recycled contents, or bio-based contents, may be stored in a decentralized database 200. One or more environmental attributes, such as the carbon footprint of a product, recycled contents, or bio-based contents, may also be stored in a database 202 associated with the data owner, such as the producer of the olefin composition 104.

[0105] The olefin composition 104 may be physically delivered to a user of the olefin composition. The olefin composition may be associated with a QR code® encoding an olefin composition identifier. The user of the olefin composition can read the QR code® using a QR code® reader 206. The olefin composition identifier may be provided to a database 208 associated with consumers of the olefin composition 104. In another embodiment, consumers of the olefin composition can retrieve the olefin composition identifier using a decentralized database 200.

[0106] In this example, the data owner may be the input material producer, output material producer, output material user, or final product producer. The data owner may include any entity that generates the data. The data generation node may be connected to the data owner or an entity that owns or produces the physical product on which the data is generated. The data may be generated by a third-party entity on behalf of the entity that owns the physical product on which the data is generated.

[0107] The data consumption service 210 may include computer executable instructions for accessing and / or processing data, such as olefin composition data associated with a data owner. The data provision service 210 may include computer executable instructions for providing and / or processing data, such as olefin composition data, associated with a data owner for access and / or processing by the data consumption service 214.

[0108] Based on the received olefin composition identifier, a request to access the environmental attributes associated with the olefin composition identifier may be triggered by the data consumption service 210, as indicated by arrow 212. The olefin composition identifier may be associated with or provided to the producer of the olefin composition 104 or to the producer's data provision service 214. Furthermore, authentication and / or authorization information may be provided.

[0109] A request may be authenticated and / or authorized to access environmental attributes associated with an olefin composition identifier. Based on the success of the authorization and / or authentication, access to the environmental attributes associated with the olefin composition identifier may be granted.

[0110] For access, the olefin composition identifier may be provided to the data provision service 214, as indicated by arrow 212. The data provision service 214 may use the received olefin composition identifier to retrieve environmental attributes associated with the olefin composition 104, as indicated by arrows 218 and 220. The environmental attributes associated with the olefin composition 104 provided to the data provision service 214 may be provided to the data consumption service 210, as indicated by arrow 216. The environmental attributes associated with the olefin composition 104 may be stored in the database 208 associated with the user of the olefin composition 104, as indicated by arrow 220.

[0111] Environmental attributes can be uniquely associated with olefin compositions using output identifiers or decentralized identifiers. A decentralized network allows for the transmission of environmental attributes between producers and users of olefin compositions. In this way, environmental attributes can be shared among value chain players without direct mediation by a central intermediary, thanks to their unique association with olefin compositions. This enables transparency of environmental attributes across the value chain, allowing for the tracking of positive environmental impacts from olefin compositions produced by the chemical production network 102 throughout the value chain.

[0112] Figure 5 schematically illustrates an example of a method or apparatus for providing environmental attributes associated with olefin compositions across a value chain via a decentralized network.

[0113] The example in Figure 5 illustrates a fully connected value chain, including a chemical production network. In this example, input material providers, olefin composition producers, olefin composition users, and end-product producers may be connected to a decentralized network as described in the context of Figure 4. Environmental attributes may be provided in the form of digital assets or olefin composition passports associated with the physical entities of input materials, olefin compositions, any intermediate products, or end products, via an ID-based schema described in the context of Figures 2-4.

[0114] An input material provider may supply input materials, such as biogas or pyrolysis oil. The environmental attributes of the input materials may be provided by a data provision service connected to a decentralized network, as described in the context of Figure 4. An olefin composition producer may produce olefin compositions from input materials provided to a chemical production network. The olefin composition producer may access environmental attributes associated with the input materials by a data consumption service connected to a decentralized network, as described in the context of Figure 4. The olefin composition producer may manage environmental attributes through a production operation system, as described in the context of Figures 1 to 3. The olefin composition producer may assign environmental attributes associated with the input materials, or environmental attributes associated with the chemical production network, such as carbon footprint, to the olefin composition, as described in the context of Figures 1 to 3. The olefin composition producer may provide environmental attributes associated with the olefin composition by a data provision service connected to a decentralized network, as described in the context of Figure 4. An olefin composition user or end product producer may access environmental attributes associated with the olefin composition by a data consumption service connected to a decentralized network, as described in the context of Figure 4.

[0115] In this example, the corresponding data owners may be input material producers, output material producers, output material users, and final product producers. Data owners may include any entity that generates data. A data generation node may be connected to a data owner or an entity that owns or produces the physical product on which the data is generated. Data may be generated by a third-party entity on behalf of the entity that owns the physical product on which the data is generated.

[0116] A data consumption service may include computer executable instructions for accessing and / or processing data associated with a data owner, such as olefin composition data. A data provision service may include computer executable instructions for providing and / or processing data associated with a data owner for access and / or processing by the data consumption service, such as olefin composition data.

[0117] In the example in Figure 5, the decentralized identifier may be associated with the final product. Such a decentralized identifier may be provided to value chain participants. Through the final product-specific decentralized identifier, data associated with the final product produced from the olefin composition can be collected across the production chain and assigned to the final product-specific decentralized identifier. For example, one or more environmental attributes associated with the final product may originate from environmental attributes associated with the olefin composition, input materials, or any other product entity present in the value chain of the final product.

[0118] In this way, the environmental attributes of input materials, olefin compositions, and all products produced from olefin compositions can be tracked throughout the value chain to the final product. By tracking the environmental attributes of materials in this manner, information can be made transparent across the value chain, and the flow of information can be controlled by the participants in the supply chain. Furthermore, environmental attributes can be handled by the production operation system according to the needs of each participant, as described in the context of Figures 1 to 3. Overall, such tracking makes positive environmental impacts transparent and attributable to individual supply chain participants, as it enables tracking of positive environmental impacts by individual supply chain participants.

[0119] Figures 6A–6C schematically illustrate examples of chemical production networks for producing olefin compositions associated with olefin composition passports or digital assets. The examples in Figure 6 are illustrative and should not be considered limiting.

[0120] In the example shown in Figure 6A, bionaphtha and fossil naphtha may be supplied to a chemical production network for producing ethylene, butene, and propylene in the first step, and oligomerized butene and isobutylene in the second step, as an example. Ethylene, propylene, butene, isobutylene, and oligomerized butene are examples of olefin compositions. Bionaphtha and fossil naphtha may be input materials as mixed raw materials in this example. Several intermediate or output materials may be produced from bionaphtha and fossil naphtha. In the illustrated example, ethylene, propylene, and butene may be intermediate or output materials. Butene may include a mixture of various butenes, e.g., 1-butene, 2-butene, and isobutylene. From the mixture of butenes, isobutylene, oligomerized butene, and other products, e.g., intermediate or output materials, may be produced.

[0121] In the example in Figure 6A, the bio-contents of bionaphtha can be tracked as a non-fossil input material. As described in the context of Figure 2, the bio-contents of bionaphtha at the start of the olefin composition production chain can be registered via the production operation system 106. Here, the bio-contents of bionaphtha can be assigned to the equilibration account 112 for bio-contents. Thus, the environmental attributes of the bio-contents of bionaphtha are separated from the mass flow of chemical processing in the chemical production network 102, as shown in Figure 6A.

[0122] The bio-contents of bionaphtha can be determined based on the attribution of the bio-contents of bionaphtha used to produce olefin compositions. The bio-contents of bionaphtha, attributable to the production of ethylene, propylene, butene, isobutylene, and oligomerized butene, may also be based on the conservation of mass attributable to the produced olefin composition. For example, half of the bio-contents of bionaphtha may be attributable to a mixture of butenes, while a quarter may be attributable to ethylene and propylene, respectively, derived from bionaphtha as input materials. The environmental attributes of the bio-contents may thus be due to their distribution across various olefin compositions.

[0123] In the example shown in Figure 6B, pyrolysis oil and fossil naphtha obtained from chemical recycling may be supplied to a chemical production network for producing ethylene, butene, and propylene in the first step, and oligomerized butene and isobutylene in the second step. Ethylene, propylene, butene, isobutylene, and oligomerized butene are examples of olefin compositions. Pyrolysis oil and fossil naphtha obtained from chemical recycling may be input materials as mixed raw materials in this example. Several intermediate or output materials may be produced from pyrolysis oil and fossil naphtha obtained from chemical recycling. In the illustrated example, ethylene, propylene, and butene may be intermediate or output materials. Butene may include mixtures of various butenes, e.g., 1-butene, 2-butene, and isobutylene. From the mixture of butenes, isobutylene, oligomerized butene, and other products, e.g., intermediate or output materials, may be produced.

[0124] In the example in Figure 6B, the contents of pyrolysis oil obtained from chemical recycling can be tracked as a non-fossil input material. As described in the context of Figure 2, the pyrolysis oil regeneration system contents at the start of the olefin composition production chain can be registered via the production operation system 106. Here, the pyrolysis oil regeneration system contents can be assigned to the equilibration account 112 for regeneration system contents. Thus, the environmental attributes of the pyrolysis oil regeneration system contents are separated from the mass flow of chemical processes in the chemical production network 102, as shown in Figure 6B.

[0125] The contents of a pyrolysis oil regeneration system can be determined based on the attribution of these contents to the pyrolysis oil used in producing olefin compositions. The contents of a pyrolysis oil regeneration system attributable to the production of ethylene, propylene, butene, isobutylene, and oligomerized butene may also be based on the conservation of mass attributable to the produced olefin composition. For example, half of the contents of a pyrolysis oil regeneration system may be attributable to a mixture of butenes, while a quarter may be attributable to ethylene and propylene, respectively, derived from the pyrolysis oil as input materials. The environmental attributes of the contents of the regeneration system can thus be attributable to various olefin compositions.

[0126] In the example in Figure 6C, bionaphtha, pyrolysis oil obtained from chemical recycling, and fossil naphtha may be supplied to a chemical production network for producing ethylene, butene, and propylene in the first step, and oligomerized butene and isobutylene in the second step. Ethylene, propylene, butene, isobutylene, and oligomerized butene are examples of olefin compositions. Bionaphtha, pyrolysis oil obtained from chemical recycling, and fossil naphtha may be input materials as mixed raw materials in this example. Several intermediate or output materials may be produced from bionaphtha, pyrolysis oil obtained from chemical recycling, and fossil naphtha. In the illustrated example, ethylene, propylene, and butene may be intermediate or output materials. Butene may include a mixture of various butenes, e.g., 1-butene, 2-butene, and isobutylene. Butene mixtures can produce isobutylene, oligomerized butene, and other products, such as intermediate or output materials.

[0127] In the example in Figure 6C, the bio-contents of bionaphtha and the contents of pyrolysis oil obtained from chemical recycling may be tracked as non-fossil input materials. As described in the context of Figure 2, at the start of the olefin composition production chain, the bio-contents of bionaphtha and the recycled contents of pyrolysis oil may be registered via the production operation system 106. Here, the bio-contents of bionaphtha and the recycled contents of pyrolysis oil may be assigned to the equilibration account 112 for bio-contents and recycled contents. Thus, the environmental attributes of the bio-contents of bionaphtha and the environmental attributes of the recycled contents of pyrolysis oil are separated from the mass flow of chemical processing in the chemical production network 102, as shown in Figure 6C.

[0128] The bio-contents of bionaphtha and the recycled contents of pyrolysis oil used to produce olefin compositions can be determined for their respective purposes. The bio-contents of bionaphtha and the recycled contents of pyrolysis oil, which are attributed to the production of ethylene, propylene, butene, isobutylene, and oligomerized butene, may also be based on the conservation of mass attributed to the produced olefin composition. For example, half of the bio-contents of bionaphtha and half of the recycled contents of pyrolysis oil may be attributed to a mixture of butenes, while a quarter of the bio-contents of bionaphtha and a quarter of the recycled contents of pyrolysis oil may be attributed to ethylene and propylene derived from bionaphtha and pyrolysis oil as input materials, respectively. The environmental attributes of the bio-contents and the recycled contents may be attributed to various olefin compositions to this extent.

[0129] In the system shown in Figure 2, environmental attributes associated with the production of an olefin composition can be attributed to the produced olefin composition by associating a decentralized ID with the olefin composition and assigning the environmental attributes to the decentralized ID. By relating the ID to the environmental attributes, the environmental attributes can be uniquely associated with the produced olefin composition. The olefin composition can be delivered to the olefin composition user. The packaging or means of transport may include a QR code®. The decentralized ID may be included in or encoded within the QR code®. In this way, the olefin composition user can access the environmental attributes associated with the olefin composition via the ID-based protocol described in the context of Figures 4 and 5.

[0130] Similar to this example, a chemical production network for producing olefin compositions associated with digital assets may also be based on the carbon footprint method shown in Figure 3.
