Advantageously, the benefits provided by any of the embodiments and examples equally apply to all other embodiments and examples. EMBODIMENTS

[0023] In the following, embodiments of the present disclosure will be outlined by ways of embodiments and / or example. It is to be understood that the present disclosure is not limited to said embodiments and / or examples.

[0024] "Chemical process(s)" are to be understood as any process that is employed to change the chemical properties of a substance in a way that changes the substance with the aim to create or improve the aroma properties of the changed compared to the unmodified substance, typically the input material. Chemical process(s) used in the invention may employ chemical reactions in situ and I or ex situ and therefore may be a process using chemical means and / or biological means to modify the substance for aroma use. Chemical process(s) also includes the purification step employed after the substance is produced. Examples are chemical processes to produce Citral ((3,7 dimethyl-octa-2,6- dienal), for example as disclosed in the international patent application WO 2008 / 037693, and further aroma chemicals therefrom; or biological processes like fermentation-based methods to produce aroma chemicals for example as in the international patent application WO 2011 / 074954; or processes employing enzymatic conversion of substances or combination of such processes. The examples are given as exemplary illustrations and are not to be taken as limiting the invention.

[0025] “Chemical production network" is to be understood to refer to a network that employs one or more chemical process(s) as defined above in the production of one or more aroma chemicals. In one embodiment the chemical production network produces one or more aroma compositions comprising one or more aroma chemicals made by the chemical production network.

[0026] Any reference to “an aroma chemical" in this application is to be understood to encompass one or more aroma chemicals as well For improved reading the term “an aroma chemical” is used but not meant to be limited to a single or only one aroma chemical. Hence, the term “producing an aroma chemical'' is to be understood to encompass methods or production networks where more than one aroma chemical is produced, and hence producing one or more aroma chemical(s). Each of these may then be associated with an aroma chemical passport or digital asset according to the invention. For clarity similarly phrases like “providing the produced aroma chemical in association with the aroma chemical passport or digital asset” are to be understood to encompass situations where more than one aroma chemical is provided associated each with its aroma chemical passport or digital asset.

[0027] Determining, generating includes initiating or causing to determine, generate. Providing includes “initiating or causing to access, determine, generate, send or receive”. “Initiating or causing to perform an action" includes any processing signal that triggers a computing node to perform the respective action.

[0028] The methods, the systems, aroma chemicals, aroma chemical passports or digital assets and the computer elements disclosed herein provide an efficient, secure and robust way for sharing or exchanging environmental impact data across different participant nodes in value chains. In particular, by providing aroma chemical specific data via the aroma chemical passport or digital asset, environmental impacts can be shared and made transparent from the aroma chemical to the product produced from such aroma chemical. The aroma chemical passport or digital asset enables secure data exchange, since data access can be controlled by the aroma chemical provider, e.g. the entity providing the aroma chemical. The exchanged data assets can be specific to the aroma chemical as produced and tailored to the needs of the consumer of the aroma chemical. This way an improved tracking and tracing of aroma chemicals can be achieved by securely providing environmental impact data in diverse and highly complex value chains. The environmental impact of aroma chemical can hence be tracked leading to simpler, more efficient and sustainable handling of aroma chemical by value chain participants.

[0029] Aroma chemicals, especially fragrances, are of great interest, especially in the field of cosmetics, cleaning and laundry compositions. Another example are flavor substances for food and feed use. Of special interest are aroma chemicals, which can impart one or more distinct sensory impressions to a composition, thereby contributing to a rich and interesting sensory profile, especially an olfactory profile of the composition.

[0030] Small changes in chemical structure bring about massive changes in the sensory properties such as odor and / or flavor, the targeted search for substances with certain and distinct sensory properties such as a certain odor is extremely difficult. The search for new aroma chemicals is therefore in most cases difficult and laborious without knowing whether a substance with the desired odor and / or flavor will even actually be found. Further, the aroma chemicals should be obtainable from readily available starting materials, allowing their fast and economic manufacturing. The endeavor is to obtain new aroma chemicals with more positive environmental attributes as in the past, for example but not limited to those from renewable sources, especially biomass such that the product carbon footprint is reduced. Attempts are also being made to reduce the climate gas emission of the entire production process right from the production plant to the store shelf.

[0031] Aroma chemicals associated with the aroma chemicals passport or digital asset may be selected from the class of hydrocarbons, aliphatic alcohols, aliphatic aldehydes and acetals thereof, aliphatic sulfur-containing compounds, aliphatic nitriles, esters of aliphatic carboxylic acids, acyclic terpene alcohols, acyclic terpene aldehydes and ketones, cyclic terpene aldehydes and ketones, cyclic alcohols, cycloaliphatic alcohols, cyclic and cycloaliphatic ethers, cyclic and macrocyclic ketones, cycloaliphatic aldehydes, cycloaliphatic ketones, esters of cyclic alcohols, esters of cycloaliphatic alcohols, esters of cycloaliphatic carboxylic acids, araliphatic alcohols, esters of araliphatic alcohols and aliphatic carboxylic acids, araliphatic ethers, aromatic and araliphatic aldehydes, aromatic and araliphatic ketones, aromatic and aliphatic carboxylic acids, nitrogen-containing aromatic compounds, phenols, phenyl ethers and phenyl esters, heterocyclic compounds, lactones

[0074] In a preferred embodiment, the composition comprises at least one aroma chemical and at least one antioxidant and optionally at least one aroma chemical different from (i). Deodorant-active agents

[0075] Deodorizing compositions (deodorants and antiperspirants) counteract, mask or eliminate body odors. Body odors are formed through the action of skin bacteria on apocrine perspiration which results in the formation of unpleasant-smelling degradation products.

[0079] Where perspiration is present in the underarm region, extracellular enzymes-esterases, mainly proteases and / or lipases are formed by bacteria and split the esters present in the perspiration, releasing odors in the process. Suitable esterase inhibitors are for example trialkyl citrates, such as trimethyl citrate, tripropyl citrate, triisopropyl citrate, tributyl citrate and, in particular, triethyl citrate. Esterase inhibitors inhibit enzyme activity and thus reduce odor formation. The free acid is probably released by the cleavage of the citric acid ester and reduces the pH value of the skin to such an extent that the enzymes are inactivated by acylation. Other esterase inhibitors are sterol sulfates or phosphates such as, for example, lanosterol, cholesterol, campesterol, stigmasterol and sitosterol sulfate or phosphate, dicarboxylic acids and esters thereof, for example glutaric acid, glutaric acid monoethyl ester, glutaric acid diethyl ester, adipic acid, adipic acid monoethyl ester, adipic acid diethyl ester, malonic acid and malonic acid diethyl ester, hydroxycarboxylic acids and esters thereof, for example citric acid, malic acid, tartaric acid or tartaric acid diethyl ester, zinc glycinate and mixtures of two or more of the aforementioned.

The production operating system 106 may be configured to ingest such environmental attributes and to track the environmental attributes across the chemical production network 102 from input materials 100 to output materials), in particular aroma chemical(s), 104.

[0144] The chemical production network 102 may include multiple interlinked processing steps. The chemical production network 102 may be an integrated chemical production network 102 with interrelated production chains. The chemical production network 102 may include multiple different production chains that have at least one intermediate product in common. The chemical production network 102 may include multiple stages of the chemical value chain. The chemical production network 102 may include the producing, refining, processing and / or purification of gas or crude oil. The chemical production network 102 may include a stream cracker, or a syngas plant connected to multiple production chains that output products 104 from the effluent of such plants. The chemical production network 102 may include multiple production chains that output from one or more input material(s) 100 one or more output material(s), in particular aroma chemical(s), 104. The chemical production network 102 may include multiple tiers of a chemical value chain. The chemical production network 102 may include a physically interconnected arrangement of production sites. The production sites may be at the same location or at different locations. In the latter case the production sites may be interconnected by means of dedicated transportation systems such as pipelines, supply chain vehicles, like trucks, supply chain ships or other cargo transportation means.

[0145] The chemical production network 102 may chemically convert input materials 100 to one or more output material(s), in particular aroma chemical(s), 104. The chemical production network 102 may convert input materials 100 by way of chemical conversion to one or more output material(s), in particular aroma chemical(s), 104.

[0146] The input materials 100 may be fed to the chemical production network 102 at any entry point The input materials 100 may be fed to the chemical production network 102 at the start of the chemical production network 102. Input materials 100 may for example make up the feedstock of a steam cracker. The input material 100 may include non-fossil input material, such as bio-based or recycled material, and / or fossil input material for the manufacture of chemical intermediates and chemical output materials), in particular aroma chemical(s), 104.

[0147] 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 production processes. The system boundary may be defined by the site of the chemical production network 102. The system boundary may be defined by production processes controlled by one entity or multiple entities jointly. The system boundary may be defined by value chain with staggered production processes to an end product, which may be controlled by multiple entities separately. The chemical production network 102 may include a waste collection and sorting step, a recycling step such as pyrolysis, a cracking step such as steam cracking, a separation step to separate intermediates of one process step and further processing steps to convert such intermediates to output material(s), in particular aroma chemical(s), 104 leaving the system boundary of the chemical production network 102.

[0148] 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 the different processes. One process step monitored and / or controlled may be the feed of input materials 100 or the release of output material(s), in particular aroma chemical(s), 104. Another process step monitored and / or controlled may be the registration of environmental attributes associated with input materials 100 entering the system boundary of the chemical production network 102. Yet another process step monitored and / or controlled may be the attribution of environmental attributes to output materials), in particular aroma chemical (s), 104 produced via the chemical production network 102. Yet another process step monitored and / or controlled may be the management of environmental attributes associated with input materials 100 and output material(s), in particular aroma chemical(s), 104 of the chemical production network 102.

[0149] The production operating system 106 may be configured to register inbound environmental attributes and to assign outbound environmental attributes. The production operating system 106 may be configured to access data related the inputs materials 100, the processes and / or the output material(s), in particular aroma chemical(s), 104 used in the chemical production network 102. For example, the production operating system 106 may be configured to register a recycled or bio-based content of the one or more input material(s) 100 used in the chemical production network 102 as environmental attribute. The production operating system 106 may be configured to allocate the environmental attribute to at least one balancing account associated with the recycled or bio-based content of the input materials 100. The production operating system 106 may be configured to allocate at least a part of the environmental attributes from the at least one balancing account to the at least one output material(s), in particular to the aroma chemical (s), 104.

[0150] The production operating system 102 may be configured to handle environmental attributes related to the input materials 100 and output material (s), in particular aroma chemical(s), 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 input materials 100 impacting the environmental property of the chemical production network 102 and the output material(s), in particular aroma chemical(s) 104 produced by the chemical production network 102. Further in particular, the production operating system 102 may be configured to determine environmental attributes associated with the output material(s), in particular aroma chemical(s) 104. This way the production operating system 102 may be configured to store environmental attributes in balancing accounts or to withdraw environmental attributes from the balancing accounts. The environmental attributes may hence be viewed as a credit that may be deposited in an account or deducted from an account related to the input and output material(s), in particular aroma chemical (s), of the chemical production network 102. This way the environmental impact of the production may be tracked and / or traced.

[0151] In chemical production networks 102 multiple value chains may be linked. Additionally different input materials 100 or chemical processes impacting the environmental property of output material(s), in particular aroma chemical(s), 104 produced by the chemical production network 102 may be used. Examples of input materials 100 impacting at least one environmental property of output material(s), in particular aroma chemical(s) 104 produced from such input materials 100 are recycled, renewable or bio-based input materials 104. Examples of chemical processes impacting the environmental property include chemical processes using environmentally friendly technology such as carbon capture, carbon utilization or heat pumps.

[0152] Owing to the processing of chemicals in continuous or semi-continuous production and the complexity of chemical production networks 102, traceability of the input materials through the network may be hampered. In such scenarios, an equivalent environmental attribute signifying the impact on the environmental property of output material(s), in particular aroma chemical(s) 104 produced by the chemical production network may be allocated to balancing accounts and assigned to one or more output material , in particular aroma chemical(s), 104 of the chemical production network 102. The environmental attributes may hence be decoupled from the physical material flow inside the chemical production network 102. Decoupling may be based on the mass balance model in that the equivalent amount assigned to the one or more output material(s), in particular aroma chemical(s) may not exceed the equivalent amount provided by input materials or processes. If an equivalent amount has been allocated to the virtual account of one environmental attribute type, it may not be allocated a second time to another virtual account of the one environmental attribute type. Environmental attribute types may be recycled, bio-based, renewable or the like. Environmental attributes may be provided in the form of digital assets or aroma chemical passports attached to the physical entity of the aroma chemical.

[0153] Fig. 2 illustrates schematically an example of attributing environmental attributes associated with input materials 100 to output material(s), in particular aroma chemical(s) 104 of the chemical production network 102.

[0154] As shown in Fig. 1 the chemical production network 102 and operations of the chemical production network 102 may be monitored and / or controlled by a production operating system 106. The production operating system 106 may be configured to track environmental attributes from input materials 100 fed to the chemical production network 102 to output material(s), in particular aroma chemical(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 materials 100 provided to the chemical production network 102 and to attribute environmental attributes to output material(s), in particular aroma chemical(s), 104 produced by the chemical production network 102.

[0155] The input materials 100 such as pyrolysis oil, bio-naphtha or bio-gas may be provided to the chemical production network 102. The input materials 100 may enter the chemical production network 104 at the entry point, such as a such as a steam cracker or a syngas plant. The input materials 100 may be used in the chemical production network 102 to produce one or more output material(s), in particular aroma chemical(s), 104 from the input materials 100. output material(s), in particular aroma chemical(s), 104 may be provided at exit points of the chemical production network 102.

[0156] On entry of the input material 100, input material data 108 may be provided via a communication network to a computing interface of the production operating system 106. A data provider, such as a QR code reader, may be configured to provide material data 108 related to the one or more input material(s) 100 and respective environmental attributes 108 to a computing interface configured to allocate the environmental attributes associated with the input materials 100. The material data 108 may include the input material identifier and environmental attributes associated with the input materials 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 on, prior or after providing of the one or more input material(s) at entry points to the chemical production network 102.

[0157] The input material identifier may be linked to the environmental attribute(s) associated with the respective input materials) 100, the amount of input material 100 and the certificate certifying the environmental attribute(s). The amount of input material may be a measured amount of input material 100 fed to a plant or storage of the chemical production network 102 for producing one or more output material(s), in particular aroma chemical(s) 104 from the input material(s) 100. The input material identifier associated with the respective input material 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 on entry to chemical production network 102, or the data may be transferred from a computing system to the production operating system 106.

[0158] An inbound allocator 110 may be configured to allocate the one or more environmental attribute(s) to at least one balancing account 112 associated with the respective environmental attribute. For example, one balancing account 112 may relate to environmental attributes from recycled material and another balancing account 112 may relate to environmental attributes from bio-based material. The balancing account may be associated with the respective environmental attribute type, such as bio-based or recycled. Based on such association the balancing account associated with the environmental attribute type of the respective input material 100 may be selected The environmental attributes may be allocated to the selected balancing account. For example, the account 112 for recycled material may be selected and the environmental attribute may be allocated to such account 122.

[0159] To allocate, the one or more environmental attribute(s) may be converted to balancing units and the balancing units may be allocated to the balancing account 122. The conversion may be based on a conversion factor such as mass, weight, carbon atoms, hydrogen atoms, methane equivalents or any other suitable measure for quantifying the environmental impact of the environmental attribute. The conversion factor may hence take into account the difference between producing chemical products from conventional input material(s) and producing chemical products from non- conventional input material(s) or producing chemical products from a mix of conventional and non-conventional input materials. The conversion factor may relate to differences in chemical and / or physical properties of conventional and non-conventional input material(s).

[0160] By using the balancing accounts 112 it can be ensured that environmental attributes of input materials 100 are only used once for assignment to aroma chemicals 104. This way double counting on input or output is avoided to ensure positive environmental impact can be reliable tracked and assigned to aroma chemicals 104. An identifier provider 116 may be configured to provide the aroma chemical identifier associated with the aroma chemical produced by the chemical production network 102 and provided at the exit point from the chemical production network 102.

[0161] An outbound assignor 114 may be configured to assign at least one environmental attribute from the at least one balancing account 112 associated with the respective environmental attribute to the aroma chemical identifier ID2. One or more environmental attribute(s) may be assigned to the at least one aroma chemical identifier ID2. Assignment may include de-allocation of the one or more environmental attributes from the balancing account 112 associated with the respective environmental attribute type. Assignment may include converting one or more balancing unit(s) to one or more environmental attribute(s).

[0162] Assigning at least one environmental attribute associated with input material(s) to aroma chemical(s) may include the linking of the aroma chemicals identifier ID2 with the environmental attribute. The aroma chemical identifier ID2 may be associated with the physical entity of the aroma chemical. This way the virtual identifier of a material may be uniquely linked to the physical material. Such linking may include a physical or virtual link of identifiers uniquely associated with the physical material. For physical linking a tag or code may be physically connected to the material, e.g., by printing a QR code on the packaging. For virtual linking different identifiers associated with the physical material may be linked. For example, an order number, a batch number, LOT number or a combination thereof may be linked.

[0163] The outbound assignor 114 may be configured to provide the environmental attributes associated with the aroma chemical to a data consumer, such as a system associated with a user of the aroma chemical. The outbound assignor 114 may be configured to provide the environmental attributes associated with the aroma chemical to a decentral network as will be described in the example of Fig. 4. Environmental attributes may be provided via the above ID based schema in the form of digital assets or aroma chemical passports associated with the physical entity of the aroma chemical.

[0164] Fig. 3 illustrates schematically an example of attributing environmental attributes of input materials 100 and chemical processes to the aroma chemical 104 of the chemical production network 102.

[0165] As described in the context of Figs. 1 and 2 the chemical production network 102 and operations of the chemical production network 102 may be monitored and / or controlled by a production operating system 106. Input materials 100 such as pyrolysis oil, bio-naphtha or bio-gas may be provided to the chemical production network 102. The input materials 100 may be used in the chemical production network 102 to produce one or more aroma chemical(s) 104 from the input materials 100.

[0166] On entry of the input material 100, input material data 108 may be provided via a communication network to a computing interface of the production operating system 106. A data provider, such as a QR code reader, may be configured to provide material data 108 related to the one or more input material(s) 100 and respective environmental attributes 108 to a computing interface configured to allocate the environmental attributes associated with the input materials 100. The material data 108 may include the input material identifier and environmental attributes associated with the input materials 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 linked to the carbon footprint of the input material 100 as environmental attribute. The material data may be provided on, prior or after providing of the one or more input material(s) at entry points to the chemical production network 102.

[0167] The inbound allocator 110 may be configured to retrieve the one or more environmental attribute(s) and to provide such attributes to the carbon footprint (CF) generator 120. A process data provider 122 may be configured to gather process data associated with the chemical processing of the input material(s) 100 to produce the aroma chemical(s) 104. The process data provider 122 may be configured to gather energy data associated with the energy consumption of the chemical processing. The process data provider 122 may be configured to provide the process data and the energy data to the CF generator 120.

[0168] The CF generator 120 may be configured to determine the carbon footprint of the aroma chemical produced by the chemical production network. The carbon footprint of the of the aroma chemical may be determined based on the process data, the energy data and the carbon footprint of the input material(s) 100 used to produce the aroma chemical.

[0169] An identifier provider 116 may be configured to provide the aroma chemical identifier associated with the aroma chemical produced by the chemical production network 102 and provided at the exit point from the chemical production network 102.

[0170] An outbound assigner 114 may be configured to assign the determined carbon footprint to the aroma chemical identifier ID2 One or more environmental attribute(s) may be assigned to the at least one aroma chemical identifier ID2, such as described in the context of Fig. 2.

[0171] The outbound assigner 114 may be configured to provide the environmental attributes, in particular the carbon footprint, associated with the aroma chemical to a data consumer, such as a system associated with a user of the aroma chemical. The outbound assigner 114 may be configured to provide the environmental attributes associated with the aroma chemical to a decentral network as will be described in the example of Fig. 4. Environmental attributes may be provided via the above ID based schema in the form of digital assets or aroma chemical passports associated with the physical entity of the aroma chemical.

[0172] Fig. 4 illustrates schematically an example of a method or apparatus for providing environmental attributes associated with aroma chemicals to a material user as data consumer via a decentral network.

[0173] The aroma chemical 104 as produced by the chemical production network 102 may be provided in association with the digital asset as described in the context of Figs. 2 and 3. The digital asset may include the aroma chemical identifier. The digital asset may include one or more environmental attribute(s) such as the product carbon footprint, recycled content or bio-based content. The digital asset may relate to one or more environmental attribute(s) such as the product carbon footprint, recycled content or bio-based content. The digital asset may include a digital representation of one or more environmental attribute(s) such as the product carbon footprint, recycled content or bio-based content.

[0174] The digital asset may further include or relate to authentication and / or authorization information linked to the aroma chemical identifier. The authentication and / or authorization information may be provided for authentication and / or authorization of a data providing service 208 and / or data consuming service 210. The aroma chemical identifier may include or relate to a decentral identifier, that is uniquely associated with the aroma chemical. The decentral identifier may be connected to the digital representation of the environmental attributes. The digital representation may include a representation for accessing the environmental attributes or parts thereof. The decentral identifier may include a Universally Unique IDentifier (UUID) or a Digital IDentifier (DID). The decentral identifier may include any unique identifier uniquely associated with a data owner and / or aroma chemical. The data owner may be the producer of the aroma chemical. Via the decentral identifier and its unique association with the data owner and / or aroma chemical access to the material configuration data may be controlled by the data owner.

[0175] The digital asset including the digital representation of one or more environmental attribute(s) such as the product carbon footprint, recycled content or bio-based content may be stored in a decentral data base 200. The one or more environmental attribute(s) such as the product carbon footprint, recycled content or bio-based content may be stored in a data base 202 associated with the data owner, such as the producer of the aroma chemical 104.

[0176] The aroma chemical 104 may be physically delivered to a user of the aroma chemical. The aroma chemical may be connected with a QR-code having encoded the aroma chemical identifier. The user of the aroma chemical may read the QR-code through a QR-code reader 206. The aroma chemical identifier may be provided to a data base 208 associated with the consumer of the aroma chemical 104. 1 n other embodiments the consumer of the aroma chemical may retrieve the aroma chemical identifier through the decentral data base 200.

[0177] The data owner in this example may be the input material producer, the output material producer, the output material user, the end product producer. The data owner may comprise any entity generating data. The data generating node may be coupled to the data owner or the entity owning or producing physical products from or for which data is generated. The data may be generated by a third-party entity on behalf of the entity owning physical products from or for which data is generated.

[0178] The data consuming service 210 may comprise computer-executable instructions for accessing and / or processing data, such as aroma chemical data, associated with the data owner. The data providing service 210 may comprise computer-executable instructions for providing and / or processing data, such as aroma chemical data, associated with the data owner for accessing and / or processing by the data consuming service 214. Based on the received aroma chemical identifier a request to access the environmental attributes associated with the aroma chemical identifier may be triggered by the data consuming service 210 as signified by arrow 212. The aroma chemical identifier may be provided to the data providing service 214 associated with or of the producer of the aroma chemical 104. In addition, authentication and / or authorization information may be provided.

[0179] The request may be authenticated and / or authorized to access the environmental attributes associated with the aroma chemical identifier. Based on successful authorization and / or authentication access to the environmental attributes associated with the aroma chemical identifier may be granted.

[0180] For access the aroma chemical identifier may be provided to the data providing service 214 as signified by arrow 212. The data providing service 214 may use the received aroma chemical identifier to retrieve the environmental attributes associated with the aroma chemical 104 as signified by arrows 218 and 220. The environmental attributes associated with the aroma chemical 104 provided to the data providing service 214 may be provided to the data consuming service 210 as signified by arrow 216. The environmental attributes associated with the aroma chemical 104 may be stored in the data base 208 associated with the user of the aroma chemical 104 as signified by arrow 220.

[0181] Through the output identifier or decentral identifier, the environmental attributes can be uniquely associated with the aroma chemical. Through the decentral network the environmental attributes may be transferred between the producer of the aroma chemical and the user of the aroma chemical. This way the environmental attributes can be shared with unique association to the aroma chemical and without central intermediary directly between the value chain players. This allows for transparency of environmental attributes across the value chain and positive environmental impacts from aroma chemicals produced by the chemical production network 102 can be tracked through the value chain.

[0182] Fig. 5 illustrates schematically an example of a method or apparatus for providing environmental attributes associated with aroma chemicals across value chains via the decentral network.

[0183] In the example of Fig. 5 a fully connected value chain including the chemical production network is illustrated. In the example, the input material provider, the aroma chemical producer, the aroma chemical user and the end product producer may be connected to the decentral network as described in the context of Fig. 4. Environmental attributes may be provided via the ID based schema described in the context of Figs. 2-4 in the form of digital assets or aroma chemical passports associated with the physical entity of the input material, the aroma chemical, any intermediate product or the end product.

[0184] The input material provider may provide the input materials such as bio-gas or pyrolysis oil. The environmental attributes of the input material may be provided through the data providing service connected to the decentral network as described in the context of Fig. 4. The aroma chemical producer may produce the aroma chemical from the input material(s) provided to the chemical production network. The aroma chemical producer may access the environmental attributes associated with the input material through a data consuming service connected to the decentral network as described in the context of Fig 4. The aroma chemical producer may manage the environmental attributes via the production operating system as described in the context of Figs. 1 to 3. The aroma chemical producer may assign the environmental attributes associated with the input materials or environmental attributes associated with the chemical production network such as the carbon footprint, to the aroma chemicals as described in the context of Figs. 1 to 3. The aroma chemical producer may provide the environmental attributes associated with the aroma chemical through the data providing service connected to the decentral network as described in the context of Fig. 4. The aroma chemical user or the end product producer may access the environmental attributes associated with the aroma chemical through the data consuming service connected to the decentral network as described in the context of Fig. 4.

[0185] The respective data owners in this example may be the input material producer, the output material producer, the output material user, the end product producer. The data owner may comprise any entity generating data. The data generating node may be coupled to the data owner or the entity owning or producing physical products from or for which data is generated. The data may be generated by a third-party entity on behalf of the entity owning physical products from or for which data is generated.

[0186] The data consuming service may comprise computer-executable instructions for accessing and / or processing data, such as aroma chemical data, associated with the data owner. The data providing service may comprise computerexecutable instructions for providing and / or processing data, such as aroma chemical data, associated with the data owner for accessing and / or processing by the data consuming service.

[0187] In the example of Fig. 5 the decentral identifier may relate to the end product. Such decentral identifier may be provided to the value chain participants. Via the end product specific decentral identifier data associated with the end product produced from the aroma chemical may be gathered across the production chain and assigned to the end product specific decentral identifier. For example, the one or more environmental attribute(s) associated with the end product may be derived from the environmental attribute(s) associated with the aroma chemical, the input material or any other product entity present in the value chain of the end product.

[0188] This way the environmental attributes of input materials, aroma chemicals and any products produced from aroma chemicals may be tracked through the value chain up to the end product. By tracking the environmental attributes of materials in such way the information can be made transparent across the value chain while the information flow can be controlled by the participants in the supply chain. In addition, the environmental attributes can be handled according to the individual participants needs by production operating systems as described in the context of Figs. 1 to 3. Overall, such tracking enables tracking of positive environmental impact by individual supply chain participants, which makes positive environmental impacts transparent and attributable to individual supply chain participants.

[0189] Fig. 6 illustrates schematically an example of a chemical production network for producing aroma chemicals associated with the digital asset. The example of Fig. 6 is an illustrative example and should not be considered limiting. In the example of Fig. 6 on the left hand side typical input materials with environmental attributes are shown. One exemplary input material could be bionaphtha - for example made from RSPO palm oil - may be provided to the chemical production network for producing as an example citral and other aroma chemicals produced therefrom. Bionaphtha may be the input materials in this example as mixed feedstock for example with naphata derived from petroleum. From bionaphtha isobutylene and other intermediate materials may be produced. From isobutylene fragrance substances and other products, such as intermediate materials or output materials, may be produced.

[0190] Other input material can be input material with a mix of carbon from renewable sources and carbon from fossil sources. Waste material as one example can have a varying degree of renewable carbon, from little in mixed unsorted household waste to more in the bio waste fraction of sorted household waste or essentially all renewable carbon from used cooking oils to name a few examples. Input material could be based on carbon that was captured from the atmosphere ("Captured carbon” in Fig. 6), for example by carbon dioxide sequestration processes to remove carbon dioxide from the atmosphere and / or from industrial off-gases. Some input material may have no renewable carbon, for examples natural gas or naphtha from petroleum, but by using these in conjunction with input material with renewable carbon, the output material may have a certain degree of renewable carbon attributed.

[0191] Another example of input material is biomass or biomass derived materials such as sugars, starches, glycerol and the like (in Fig. 6 summarized as Biomass). Such input material may be used for example in production networks to be converted to intermediates for example terpenes with the help of biological organisms (fermentation-based production network) and / or enzymes isolated therefrom (enzyme-based production network) or combination thereof with chemical processes as well. Taking terpenes as examples, these may be aroma chemicals, for example fragrance and / or flavor chemicals themselves, or intermediates for the production of fragrance aroma chemicals or flavor aroma chemicals or aroma chemicals that have both applications in fragrance and flavor use.

[0192] In the example of Fig. 6 the renewable carbon content of for example bionaphtha as non-fossil input material may be tracked. As described in the context of Fig. 2, the renewable carbon content of bionaphtha at the start of the Citral- based aroma chemical production chain may be registered via the production operating system 106. Here the renewable carbon content may be allocated to the balancing account 112 for renewable carbon content The environmental attribute renewable carbon content is hence detached from the mass flows of the chemical processing in the chemical production network 102 as illustrated in Fig. 6.

[0193] For attribution of the renewable carbon content used to produce the Citral-based aroma chemical, the renewable carbon content may be determined. The renewable carbon content attributable to Citral-based aroma chemical production may be based on mass conservation attributable to the produced Citral-based aroma chemical like Citral, menthol, linalool and others. For example, only half of the renewable carbon content may be attributable to the Citral-based aroma chemical, and the other half may be attributable to other output products resulting from the renewable carbon content as input material. The environmental attribute renewable carbon content may be attributed to such extend to the one or more Citral-based aroma chemical. In the system shown in Fig. 2, the environmental attribute associated with the production of Citral-based aroma chemical may be attributed to the produced Citral-based aroma chemical by associating the decentral ID to the Citral-based aroma chemical and assigning the environmental attribute to the decentral ID. By linking the ID and the environmental attribute, the environmental attribute may be uniquely linked to the produced Citral-based aroma chemical. The Citral- based aroma chemical may be delivered to the Citral-based aroma chemical user. The packaging such as lose bags with Citral-based aroma chemical may include a QR-code. The decentral ID may be included or encoded to the QR code. This way the Citral-based aroma chemical user may access the environmental attributes associated to the Citral- based aroma chemical via the ID based protocol described in the context of Figs. 4 and 5.

[0194] Similarly, to this example the chemical production network for producing Citral-based aroma chemical(s) associated with the digital asset may be based on the method illustrated in Fig. 3 for carbon footprints.

[0195] Other input materials may be used to generate other aroma chemicals with associated environmental attributes or digital assets similarly. Environmental attributes other than renewable carbon may be attributed to input material. For example, terpene-based aroma chemicals may be produced with biomass and biomass derived substances as input material from e.g. ecological or sustainable agriculture as environmental attributes in addition to the environmental attribute of renewable carbon content of the input material. The terpene-based aroma chemicals may then have the associated environmental attribute of being made with input material from such agricultural practices.

[0196] In another aspect, the aroma chemicals are obtained from naturally occurring plant oils or essential oils. These oils comprise complex mixtures of various chemical components and are commonly known for use as fragrances. Essential oils usually have complex compositions (>300 organic compounds, e.g , alkaloids, flavonoids, phenolic acids, saponins and terpenes) and are obtained from botanically defined plant raw materials by dry / steam distillation or a suitable mechanical process (without heating). The yield of such processes is approximately in the range of 1% Such processes lead to increased carbon footprint and / or climate gas emission due to the usage of energy in the form of steam for the extraction process, use of water or other solvents for the extraction essential oils / fragrances. If agricultural plants for example are used as a source for essential oils, the land use for their production can be a negative factor, as it may compete for the agricultural land and water needed to produce food plants. Use of the wild plants or animals also depletes limited natural resources and has adverse effects on biodiversity. As an alternative, biotechnology production networks create accessible and affordable offerings for the rising demand for natural food and flavor ingredients. Fermentation technology can be used to obtain fragrances with fewer impact on the environment and by overall reducing the carbon footprint of the product and in addition carry other positive environmental attributes. Such products obtained by the fermentation process are non-synthetic and may also use biomass / biofuel as the starting material. Thus, a sustainable network between the natural resources, biomass and newer technologies like biotechnology I fermentation process can be established to produce new flavour and fragrance compounds (i.e. aroma chemicals), and the present invention allows to provide the associated environmental attributes to products of such production networks or aroma chemicals. Recycled plastics and polymers and other fossil-based material ("Recycled fossil carbon” in Fig. 6) may be the source for yet other input material, and albeit the environmental attribute of renewable carbon will be similar to other fossilbased input material, these input materials have the environmental attribute of recycling derived material, which can also be an environmental attribute associated with the output material.
