Predecessor of this event used to be three clustering events on Open-Innovation organized 2022 in Brussels (Belgium), 2023 in Esch-surAlzette (Luxembourg) and 2024 in Kaiserslautern (Germany), where digitalization aspects of B2B2B value chain integration had been discussed from an open-innovation facilitation angle. The follow up DPP4EU-25 conference was initiated, conceptualized and organized by three EU-funded projects: DigiPass CSA, CIRPASS-2 and THESEUS, greatly supported and guided by the European Commission Directorates-General DG-RTD and DG-CNECT, and assisted by the European Commission Health and Digital Executive Agency (HaDEA). In particular, the organization committee of DPP4EU-25 is thankful to Sophia Fantechi (DG RTD), Fani Tsirantonaki (HaDEA), Martin Policar (DG RTD), and Thomas Ebert (DG CNECT), for their dedication, support and help. Moreover, the organization committee would like to thank all projects and authors who discussed from a multi-disciplinary perspective the DPP development, challenges and possible solutions. Short Overview: The DPP4EU-25 was dedicated to digitalization, Digital Product Passport (DPPs) and management of materials,product information & data as a tool to support sustainability, and circularity. The conference had been designed as a clustering event and as a forum for experts from European-funded initiatives related to DPP developments. Open questions and the exchange of insights regarding DPPs’ technical implementation, the role of IT infrastructures, implications for digitalization of manufacturing, correlations with Safe and Sustainable by Design (SSbD) frameworks, and digital business models were discussed in 7 technical sessions, aposter session, a Panel Discussion on the “DPP and Material Digitalization Future” and an Open Microphone session. The event addressed topics relevant to multiple European Commission DGs: DG RTD, DG CNECT, DG GROW, and DG ENVI, and representatives from all these DGs actively participated in the conference. The technical sessions were focused on the following aspects: •Ecodesign for Sustainable Products Regulation (ESPR) and other related regulations and their links to Digital Product Passports (DPPs) →Session 1: Regulations & Standards. •DPPs’ contributions to circular economy goals such as reuse, recycling, and waste reduction →Session 2: DPPs Barriers, Challenges and Opportunities. •Digital platforms and tools (Large Research Infrastructures, Open Innovation Platforms and Test Beds, Materials Acceleration Platforms, Factories of the Future, and Digital Innovation Hubs) supported the successful implementation of DPPs. →Session 3: Technical Requirements and Implementation of DPPs. •Role of Artificial Intelligence and emerging technologies in the development and optimization of DPPs and materials digitalization systems →Session 4: Emerging Technologies for DPPs. •Digitalization of Safe and Sustainable by Design (SSbD) principles and research-driven methodologies for seamless integration into industrial production and supply chains →Session 5: Bridging Sustainable by Design Principles, Innovation and Manufacturing through DPPs. •Manufacturing process data used to enhance DPPs, including business-to-business (B2B) and business-to-research (B2RTO) data sharing →Session 6: Enabling industrial and manufacturing data ecosystems. •Business potential/value of DPPs as assets in digital platforms, open innovation strategies, and sustainable business models across multiple industries →Session 7: From research to commercial valorization.

Page 9 ID: 106 Time: 16:20Title: BatteryPass-Ready: Enabling Digital Product Passports for Batteries in the EU Regulatory Landscape Project Reference: BatteryPass-Ready; German Ministry for Economic Affairs and Climate Action Johannes Simb¨ ock Acatech [email protected] Abstract: With the entry into force of the EU Battery Regulation No. 2023/1542, Digital Product Passports (DPP) will be mandatory for all electric vehicle and light transport vehicle batteries as well as for industrial batteries >2 kWh by February 2027. A decentralised system made up of interlinked components will be operated by the European Commission (registration), the distributor (decentralised data storage and provision) and IT service providers (backup). In view of the complexity of the overall project and its degree of novelty, the Batterypass-Ready consortium develops a test environment allowing distributors and service providers to check their individual solutions for conformity with standards during the development phase. This environment should cover the following core functionalities, which would otherwise have to be created by each individual provider: •Definition of test procedures •Analysing ongoing developments for mandatory data points and generating test data or incorporating test data provided by the user •Execution, monitoring, and logging of tests •Creation of emulation environments, in particular for components by the European Commission (e.g. registry) •Connection of the systems to be tested and the data sources. The test environment is used from a technical perspective (e.g. for interaction tests), for initial development and for maintenance and expansion. Furthermore, testing is carried out for the conformity of the DPP for new or updated products. In addition, the solution is to be used, for example, for connecting partners in the value-added system (e.g. for repair workshops). The work is carried out in close coordination with supporting stakeholders such as associations, e.g. VDA, VDMA, ZIV, and BITKOM. At the conference we would like to showcase the project set-up, its goals and involvement options. We further discuss challenges and the approach for a test environment in the current legislative landscape.

The project aims to demonstrate DPP interoperability between the different pilots and confirm viable cross-sectoral, large-scale deployment of the DPP in real-life settings for identifiable and measurable environmental and economic benefits. Towards this goal, the project works towards the development of a proposal for a reference architecture for the European DPP system and a proposal for a core ontology. The objective is that these proposals both align with the requirements of European legislation and standards but also with the beyond-regulatory needs of industry. The project also aims to closely follow and align to international frameworks and standards for DPPs, such as the United Nations Transparency Protocol. This talk will present the CIRPASS-2 project’s strategy for wide-scale piloting thanks to its 13 pilot ecosystems. It will then present in more detail one of the project’s pilots led by BEKO. Keywords: Textiles, Electronics, Tyres, Construction, EU Regulation, Wide-scale deployments of DPP, B2B circular use cases Page 17 Session 2 - Part 1: DPPs Barriers, Challenges and Oportunities. Chairs: Salim Belouettar, Natalia Konchakova This session explores how DPPs contribute to circular economy goals such as reuse, recycling, and waste reduction. Discussions will address implementation challenges, including data availability, privacy concerns, infrastructure, and costs. Case studies will showcase successful DPP applications across industries, demonstrating their potential to foster sustainability, compliance, and consumer trust.

In the energy storage sector, vanadium redox flow batteries (VRFBs) and their carbon felt electrodes are of strategic relevance due to their high modularity, recyclability, and extended life. In this context, DPPs can play an important role in documenting material provenance, performance metrics, and end-of-life management introduced under the Ecodesign for Sustainable Products Regulation (ESPR) and further align with EU Battery Regulation [3]. This study advances the EU’s digital and green transition by developing a robust, scalable, and compliant DPP system in view of the technical requirements of VRFBs and carbon felt electrodes, addressing essential regulatory demands and practical challenges identified as critical factors in lifecycle management and circularity objectives. The DPP framework is designed to meet Annex XIII attributes requirement. Recent LCA research on VRFBs highlights the difficulty of capturing electrolyte cycles and carbon felt degradation data [4]. By addressing these data challenges, our implementation showcases more actionable circularity insights for vanadium-based storage systems. To Implement effective DPPs for VRFBs and carbon felt electrodes to ensure data-driven traceability and sustainability compliance across the battery value chain, our research explored a prototype architecture by utilizing Flutter, an open-source framework for cross-platform mobile/web development from a single codebase [1], and Firebase, a managed backend-as-a-service platform providing real-time database and user authentication support[2]. However, due to Firebase’s U.S. based data infrastructure, there are challenges for adaptability to varied deployment environments. Although this setup facilitated rapid development, it raised concerns about data residency and GDPR compliance with default data processing outside the European Union and poses potential compliance issues for European stakeholders, who might require on-premises solutions to meet data protection regulations. To address this, a comparative analysis between the existing Firebase-based architecture and a proposed migration to a backend system architecture based on Django (a Python web framework) and PostgreSQL (a relational database) is underway, focusing on aspects such as control over data residency, scalability, and better regulatory compliance. This architecture enables secure, on-premises deployment or integration with EU-compliant cloud services. It aligns with GDPR principles and supports the structured management of access rights for different stakeholders, a requirement highlighted in the Battery Passport Technical Guidance[3].

Grant Agreement ID: 101192702; CINEA Werner Rom SYRION - Systemic Research and Innovation [email protected] Abstract: The maritime sector faces significant challenges in the transition to fully electric, sustainable vessels. Key barriers include the low energy density of current battery systems, safety concerns, and the need for durable, sustainable materials. Economic viability also remains a major hurdle to widespread adoption. The planned EU Digital Battery Passport (DBP) is crucial to improve the uptake of batteries across the maritime sector, both on board and offshore, for 1st and 2nd life use. However, unlike the automotive industry, there has been relatively little focus on developing a DBP for maritime applications. To address this gap, the EU project “eWAVE - Efficient high-voltage-electric modular battery and distribution systems for sustainable waterborne vessels” aims to develop a DBP specifically for maritime batteries. This passport is intended to serve as a core element for sustainable business models and to strengthen the circular economy. First, it will facilitate a “second life” for marine batteries — enabling their reuse in mobile or stationary applications, mainly on land — and support economically viable business models. Second, it will provide essential information on materials and design (e.g., recyclability, bio-based components, flame-retardant materials, system disassembly, etc.) in line with Design for Circularity as well as Safety and Sustainability by Design principles. Building on pioneering initiatives such as the German Battery Pass project — mainly geared toward the automotive sector — eWAVE will focus on the specific conditions and requirements of shipping. A key feature of the project is the use of blockchain technology to ensure traceability, transparency, and real-time access to a battery’s historical data, enabling secure tracking throughout its lifecycle for both 1st and 2nd life applications. Ultimately, the project will develop tailored recommendations for the implementation of a DBP in electrified maritime applications.

Grant Agreement ID: 101060375; REA Guy Buyle Centexbel [email protected] Abstract: The project CISUTAC (Circular and Sustainable Textiles and Clothing) aims at increasing circularity and sustainability in textiles and clothing in Europe. The production and consumption of textile products continue to grow, together with their impact on the environment, due to a lack of reuse, repair and recycling of materials. The objective of CISUTAC is to minimise the sector’s total environmental impact by developing sustainable, novel, and inclusive large-scale European value chains. CISUTAC contributes to the DPP development by bringing important input/standardized data to software platforms for customized product information retrieval. It targets a wide range of stakeholders, focusing on the professional actors along the value chain. The project wants to help to cover industry needs and gaps for data and the harmonisation of vocabulary and formats. A guide on open data and its many facets is being compiled. This guide will include best practice recommendations and will focus on garments in general. It will include the experiences gained in the project. Therefore, the CISUTAC open data guide will provide formats that support consistent data input, use and exchange between stakeholders, ensuring for example access to data that enables sorting, reuse, repair and recycling. The CISUTAC work on the DPP is implemented as much as possible in an aligned way with relevant other initiatives, e.g. the IRISS project, thanks to the involvement of several CISUTAC partners in such initiatives.

The inclusion of safety data into the digital tracking of materials properties is not only a useful and sensible extra at this stage; rather, it is of utmost importance that the complex relationships between the structure, functionality and safety of a material are included into the data and design models that are being developed now to form the basis of the ‘by design’ character of fully digitalised materials value chains. The MACRAM´ E Project has therefore devised an R&I approach, that widens the development of harmonised test guidelines (TGs) and guidance documents (GDs) (OECD) and standards (CEN, ISO) to market-relevant Advanced Materials (AdMas) s in their complex product matrices. This will be achieved by defining the R&I Strategy through life-cycle assessment for five market-relevant industrial MACRAM´ E Use-Cases for the development of improved reporting guidelines combining community standards for materials characterisation and safety data with detailed descriptions of the complex product, biological and environmental matrices. In this course, the MACRAM´ E Information Hub has become the one-stop sharing platform for all Project partners; it ultimately aims to become directly integrated into advanced analysis, grouping and read-across applications, with the aim to strengthen European competitiveness. MACRAM´ E’s results ultimately aim to be processed and integrated into computational models for automatic data-gap filling and simulations, allowing the extension of models and approaches towards semi-automated digital workflows and guidance for future developments of decision support systems based on AI and machine learning.

Important challenges are, however, faced when considering testing different life stages of a product. In the Horizon Europe project iCare (icareproject.eu), performance standards were used and adapted to generate representative samples for the use and end-of-life stages of various prototype products (i.e., car tyres, concrete, battery casings, printed inks, and storage tanks). Concentration and size selection protocols were deployed on the collected samples to meet (eco)toxicity assay requirements (e.g., size below 10 µm, 1 mg/L, and dispersible). The relevance and applicability of such (eco)toxicity results will be discussed in the context of regulatory compliance (e.g., general product regulation, construction product regulation) and safe and sustainable frameworks, with developments regarding the implications of such data for product lifecycle information and environmental impact assessments. This project has received funding from the EU Horizon Europe programme under Grant number 101092971, and its outcomes are critical for advancing the understanding of how product data can be used to evaluate the sustainability and safety of innovative products across their entire lifecycle.

The key potential of the concept of Product Service System (PSS), besides radical improvements in the use of products, is a reduction of environmental footprint of products and services. The overall footprint of PSS is still insufficiently investigated. The services within PSS are an important, insufficiently used source of (digitalized) data on the product and its use. It is likely that digital means facilitating provision of consistent “track and trace” information on the origin, composition and entire life cycle not only of a product but of all services offered and used around the product, will offer important contribution towards achievement of full circularity for manufacturing. The key idea of PSS-Pass is to investigate how extension of DPP to Digital Product Service System Passport (DPSSP) can be effectively achieved and how it will allow for improved circularity of the manufacturing industry. The overarching hypothesis is that LCA underpinned by Machine Learning (ML) methods and informed by dynamic data paves the way to more accurate LCA while supporting PSS life cycle decision making. The collected and sharable data from DPSSP will allow to effectively apply ML as well as Digital Twin (DT) for more reliable decision-making processes concerning circularity of PSS. The project will provide Methodological Framework for definition, development and update of DPSSP, Digital Environment for DPSSP built on existing interoperability architectures, a set of ontologies and context sensitive methods and tools used in a semantic layer for improved interoperability at DPSSP Environment, novel DT-based Simulation Framework, for PSS lifecycle analysis, and AI based method/tool to forecasts the environmental impact of PSS. The PSSPass solutions will be tested and evaluated within 3 pilots in diverse sectors: home appliances, complex equipment, and textile industry. 1ATB Institut f¨ ur angewandte Systemtechnik Bremen GmbH Keywords: Digital Product Service System Passport (DPSSP), Circularity, Manufacturing, Machine Learning (ML), Life Cycle Assessment (LCA), Digital Twin (DT), Sustainability, Interoperability, Data Sharing, Methodological Frameworks, Ontologies, Context-Sensitive Tools Page 25 Session 2 - Part 2: DPPs Barriers, Challenges and Oportunities.

Achieving this requires reliable, accessible information. To support sustainable production and resource efficiency, the EU mandates Digital Product Passports (DPPs) to ensure trustworthy product data. However, the surge in data requires standardized processing and interpretation to drive real impact. Launched in 2023, the Horizon Europe CE-RISE project aims to establish an open-access information system by 2026. This proof-of-concept will demonstrate how smarter information management can enable sustainable, circular practices across the electronics value chain. Data will be aggregated from various DPP service providers, ERP systems, and organizational inputs. CE-RISE will support structured data reading/writing across platforms, ensuring interoperability and system cohesion. By merging, harmonizing, and processing product data, CE-RISE will supply key functionalities for circular strategies. These include open access to information on critical raw materials, hazardous substances, R-strategy potential (repair, reuse, remanufacture, etc.), handling guides, disassembly manuals, and more. The system will also provide open access to Product Environmental Footprint (PEF) calculations, ensuring circularity aligns with broader sustainability goals. Secure data sharing among value chain actors will be supported, maintaining confidentiality while enhancing collaboration. This presentation explores CE-RISE’s data model development to tackle interoperability challenges. We’ll show how the model enables seamless integration of diverse data sources—ERP systems, DPP providers, manual inputs—and enhances DPP usability. Finally, we’ll highlight its role in shaping DPP structures for electronics and its potential to serve as a blueprint across other sectors.

The project targets the production of high-quality end products for four specific case studies: the pharmaceutical, ammonia, fertilizer, and polymer industries. It also addresses the necessary steps for achieving market uptake. From a DPP data perspective, the project explores: •Potential DPP content for electronic devices at end-of-life, •The economic viability of tracking DPP data across different processes, •The concept of material passports for critical raw materials, and •The integration of product and material passports into the new DPPs of upcycled products. The general transformation of product and material passports is also addressed. The development of the NEO-CYCLE DPP data ecosystem actively involves all key stakeholders along the value chain from public authorities to WEEE recycling companies, technology developers, industry associations, NGOs, SMEs, and commercial companies in the targeted sectors. Special attention is given to the calculation of social sustainability KPIs. From a DPP system-perspective, the focus lies on the UNTP. The project builds on the DPPrelated open-source results (implemented with distributed ledger and blockchain) developed by the University of Catalonia and others, such as: https://ereuse.org/en/tag/dpp/ and https://idhub.pangea.org/help/en/community/ Keywords: Page 33 ID: 207 Time: 09:50Title: Governance Framework for Digital Product Passports in the Furniture Sector – The REvolve Project Project Reference: Horizon Europe Project R-Evolve, DG RTD, Project Number 101182221 Holger Berg Wuppertal Institut [email protected] Abstract: The contribution will present the approach to and the results of creating a governance framework for Digital Product passports (DPP) for the furniture sector under development in the project R-Evolve. The Framework shall stimulate Circular Economy (CE) and incentivise data sharing while aiming to cater for the protection requirements of the stakeholder groups involved. Such governance frameworks are only just being developed for most DPP-oriented projects and approaches. These frameworks aim to complement DPP-technology and system architecture development by determining the rules, rights and obligations of the stakeholders participating in DPP systems. They also complement regulations and standards by explicating more distinctively rules for the use and employment of DPP systems as well as the (CE-oriented) cooperation and data exchange therein. The governance framework is created on the premises of the current legislative and standardisation processes (ESPR and JTC 24 respectively), furniture-specific approaches to Circular Economy, co-creation sessions with stakeholders, and the creation of dedicated use cases and user stories. For the latter we build on the involvement of R&D pilots in REvolve that address the realisation of several Circular Economy strategies through data provision. R-evolve focuses on developing solutions for furniture design and business models that prioritise sustainability. It aims to systematically support the furniture industry’s transition, emphasizing CE-oriented Product-System Innovations, including CE-oriented Business Models, circular material and product design strategies, and the use of the Digital Product Passport.

As part of DYMAN, we are advancing our Ecowise integrated suite of Digital Product Passports (DPPs) and Digital Building Logbooks (DBLs) tailored for the cooling and HVAC sector and their host buildings. Ecowise DPPs and DBLs will support the first deployment of a dynamic, lifecycle-based DPP for cooling technologies, compliant with emerging interoperability standards. These DPPs will include energy consumption data, durability indicators, and circularity metrics such as maintenance logs and usage data, enabling assessment of end-of-use value and informed refurbishment decisions. The DBLs, in parallel, will provide building-level traceability and KPI reporting for data centres aligned with (EU) 2024/1364. This will also mark the first integration of linked DPPs and DBLs in the cooling domain—enabling technical data exchange (e.g. COP, capacity), lifecycle records (manufacturing to disposal), and energy data visualisation. Ecowise systems will interface with existing Building Management Systems (BMS) and the DYMAN management platform, ensuring interoperability and verifiability from a single-entry point. These innovations will be validated at TRL 4–5 through virtual piloting, with real-use data expected to support advancement toward TRL 5. Keywords: Digital Building logbooks, data centers, linked DPPs Page 35 Session 3: Technical Requirements and Implementation of DPPs. Chairs: Peter Klein, Natalia Konchakova This session will explore digital platforms and tools that can support the successful implementation of DPPs. Discussions will cover data interoperability, governance structures, and integration of open digital infrastructures to support circularity. Specific topics include the European Open Science Cloud (EOSC), the EUDAT collaborative data infrastructure and role of national research data infrastructures, material data repositories, semantic interoperability, decentralized digital identities and persistent identifiers, data immutability and blockchain solutions. Additionally, the session addresses open research data and intellectual property rights (IPR) in data sharing. Contributions from Large Research Infrastructures (LRIs), Open Innovation Platforms and Test Beds (OIPs and OITBs), Materials Acceleration Platforms (MAPs), Factories of the Future (FoF), and Digital Innovation Hubs will be explored. ID: 301 Time: 11:00Title: Innovation by Design – supporting Digital Maturity of Advanced Materials Communities Project Reference: DigiPass CSA Natalia Konchakova Helmholtz Zentrum Hereon [email protected] Abstract: DigiPass EU project has as one overarching objective to bolster the digital maturity of European stakeholders from different materials development communities, with a particular emphasis on small and medium enterprises (SMEs). In this talk, we will present an overview on an inventory of information sources and accreditation processes used by communities and stakeholders involved in advanced materials design and manufacturing for composites and prepainted metals industries. We will also discuss the importance to increase the level of digital maturity of European universities and academia. In particular, the increase of the TRL level of scientific data will enable their utilization in Digital Product Passports (DPP) and thus drive innovation-by-design approaches. Another central objective of DigiPass CSA is to couple regulatory aspects with collaborative products innovation processes on federated dataspaces, thus allowing for a seamless transition from research to production. The Ecodesign for Sustainable Products Regulation (ESPR) is the central document which strives to improve for instance on products’ circularity, carbon footprint, and other environmental sustainability aspects. Effective legislation and regulation supporting the digital transformation is currently under way, enforcing Digital Product Passports (DPP) for some industrial areas and products. The DPPs need to get implemented as part of industrial production in a collaborative fashion along distributed productionand value-chains. The integration and role of the Safe and Sustainable by Design (SSbD) principles for establishment of a DPP will be discussed. We will point the importance of the SSbD community input to collect requirements and limitations in the advanced materials data documentation and management correlated to the Digital Passport. Moreover, an example to support a digital maturity of universities and SMEs by digitalization of materials‘ data and integration of AI/ML and physics-based modeling approaches to VIPCOAT Open Innovation Platform will be showcased. The contributions of both DigiPass and VIPCOAT projects would support industry and academia to follow the Competitiveness Compass of the European Commission.

The goal is to provide support for information flows in the Circular Economy, grounded in open web standards. Key project results include a technology platform and methods for secure, decentralized data sharing of materials and product data globally, which can provide a basis for DPP data sharing. Three use cases, from different industry domains (i.e. textile, electronics, construction), have driven the research and development activities and served as test beds and demonstrators for cross-industry applicability. The presentation will demonstrate key components of the project results, including (1) the Circular Economy Ontology Network (CEON), for CE data documentation, (2) the Open Circularity Platform, showcasing how the Solid (https://solidproject.org) family of emerging standards can facilitate CE data sharing, and (3) an enhanced Circularity Thinking methodology, expanding the current Climate KIC approach (https://www.climate-kic. org/spotlight-initiatives/circularity-thinking-programme/) with new tools for innovation and analysis of CE value networks. In addition, we will show example material and information flow mappings across the three industry domains studied, along with evaluations of the aforementioned solutions in these three cases. Finally, we will exemplify how a Digital Product Passport Ontology (DPPO) (https://w3id. org/dppo/) can be modelled and used to address semantic interoperability and data sharing for DPP systems, using the same set of technologies, which is further validated based on examples from the textile and electronics use cases in Onto-DESIDE.

Key EU frameworks (Battery Regulation, ESPR, CS3D) require DPPs to include detailed supply chain information to improve product traceability. The MaDiTraCe project recognizes that DPPs can be more than regulatory tools. When integrated within an architecture based on trust and data sovereignty, they can enhance compliance, sustainability, and circularity. This contribution presents the modular architecture developed in MaDiTraCe to support DPPs for critical raw materials. It ensures that all data is accurate, traceable, and issued by a legitimate source, enabling compliance with verification processes. The architecture relies on self-sovereign identity (SSI), verifiable credentials (VCs), and decentralized identifiers (DIDs). DPP data attributes are stored in standardized formats, aligned with cross-sectoral initiatives like Catena-X, CIRPASS, and the Battery Pass Consortium. To ensure interoperability, open standards such as W3C VCs enable direct connectivity among stakeholders using SSI principles. The did:ebsi identifier, based on the European Blockchain Services Infrastructure, is used to ensure DPP data and verifications remain accessible over time. A preliminary risk analysis identified the need for data security and integrity. In response, an optional blockchain layer enables on-demand notarization, reinforcing data trustworthiness without compromising modularity. An ongoing research direction explores integrating material and artificial fingerprints into the DPP. While these offer strong potential to anchor physical products—and their geographical provenance—to digital counterparts, challenges remain in standardization, interoperability, and secure linkage to verifiable credentials.

Central to its approach is the DPP, a blockchain-enabled repository that securely manages product traceability, lifecycle data, and sustainability metrics. ENCIRCLE aims to deploy and scale DPP implementations in two manufacturing use cases: the steel and home appliances industries. A key technical contribution of ENCIRCLE is the development of a blockchain-enabled track-and-trace framework, which equips each product with a DPP prototype at market readiness. This passport builds upon ZINQ’s existing prototype DCPP for the steel industry and integrates sustainability and circularity data—both directly measured and AI-estimated—and is stored on secure, tamper-proof blockchain infrastructure. Energy efficient consensus algorithms (e.g., Proof-of-Stake) are leveraged to maximize energy efficiency, while authentication and authorization protocols verify that only validated stakeholders (e.g., manufacturers, distributors, recyclers) can access appropriate product data. Industrial IoT sensors coupled with AI-driven methodologies, such as soft sensors and Digital Twins, establish a Virtual Production Line, facilitating real-time monitoring and lifecycle auditing from production to end-of-life, enriching the DPP with actionable and updatable data. To support the circular economy, ENCIRCLE introduces an AI-supported DPP wallet mobile app based on decentralized applications. This consumer oriented wallet targeting the home appliances use case enables users to register, track, and manage their products. A Digital Marketplace powered by AI recommendation systems delivers personalized offers to consumers for product recycling, resale, or refurbishment. AR enhanced by Computer Vision algorithms (semantic segmentation, object detection) provides real-time sustainability insights and interactive guidance for product repair and maintenance, accessible through smart glasses or mobile devices.

It targets the manufacturing sector with three pilot products from aeronautics, consumer electronics, and warehousing. For each pilot, a Digital Product Passport (DPP) solution has been developed among other DaCapo tools. The DaCapo DPP is designed not only for regulatory compliance but also as a facilitator for circular economy practices, serving as an enabler and gateway for applications such as the Electronic Maintenance Book. The technical design of the DaCapo DPP is based on Asset Administration Shells (AAS), combined with the Eclipse Dataspace Components (EDC) framework to address data sovereignty requirements. Tooling frameworks such as Semantic Treehouse are being explored for semantic modeling of DPP data and for mapping DPP data to FAIR (Findable, Accessible, Interoperable, Reusable) ontologies. The development of the DaCapo DPP focuses on minimum-viable prototyping, relevance to project use cases, post-project extensibility, and adherence to legislation and industry best practices. The DPP integrates with various other DaCapo tools: the Modular Digital Thread tool functions as a product-centered data management scheme within the OEM, linking product, process, and resource data flows, while the GRETA sustainability calculation tool provides updated assessments of sustainable and circular economy indicators for DPP. The DaCapo platform also includes middleware featuring an Orion Context Broker establishing a data lake and interoperable layer for the DaCapo platform. Validation of the DaCapo platform and DPP will occur through didactic factory facilities of DaCapo RTOs as well as real production environments. Further development of the DPP concept will proceed under another EU Horizon project, DigInTraCE, through the integration of smart tagging solutions into DPP.

Soeteman-Hernandez National Institute for Public Health and the Environment [email protected] Abstract: The Ecodesign for Sustainable Products Regulation (ESPR) is a major European legislative initiative aimed at improving the environmental sustainability of products sold in the European Union (EU). The regulation is part of the European Green Deal and the Circular Economy Action Plan. The ESPR contributes to the objectives of EU industrial policy to boost the supply of and demand for sustainable goods, deliver on sustainable production, and ensure a level playing field for products sold on the internal market. Key Ecodesign product aspects include (a) product durability and reliability; (b) product reusability; (c) product upgradability, reparability, maintenance and refurbishment; (d) the presence of substances of concern in products; (e) product energy and resource efficiency; (f) recycled content in products; (g) product remanufacturing and recycling; (h) products’ carbon and environmental footprints; (i) products’ expected generation of waste materials. From an innovation perspective, the European Commission’s (EC) Joint Research Center (JRC) has developed a Safe and Sustainable by Design (SSbD) framework and methodological guidance as a voluntary approach to guide the innovation process for chemicals, materials, products and manufacturing processes. SSbD aims to i) steer the innovation process towards the green and sustainable industrial transition, ii) minimise the production and use of substances of concern, in line with, and beyond existing and upcoming regulatory obligations, and iii) minimise the impact on health, climate and the environment during sourcing, production, use and end-oflife of chemicals, materials, products and manufacturing processes. The SSbD framework is composed of a (re-)design phase and an assessment phase that are applied iteratively as data becomes available. The (re-)design phase consists of the application of guiding principles to steer the development process. The goal, the scope and the system boundaries – which will frame the assessment of the chemical or material – are defined in this phase. The assessment phase comprises of hazard, workers exposure during production, exposure during use and lifecycle assessment. The assessment can be carried out either on newly developed chemicals and /or materials, or on existing chemicals and or materials to improve their safety and sustainability performance during production, use and /or end-of-life. The alignment between the ESPR key Ecodesign aspects and the EC JRC SSbD framework and methodological guidance, as well as how to couple the innovation process seamlessly with the digital product passport (DPP), will be discussed. This can be done by for instance, feeding the SSbD assessment data into the DPP [e.g., Composition (incl. critical raw materials), Lifecycle data (CO2, water, energy), Safety data (toxicology, exposure), Repair /disassembly instructions] and ensuring compatibility with upcoming EU DPP Delegated Acts (e.g., battery passport standards). In a feedback loop, the DPP can support not only traceability but also continuous improvement of product safety and sustainability.

The objective is quality control of recycled and virgin plastic—from specification to use, EOL, and recycling. The approach enables full traceability of ABS plastic and its constituents, designed to be applicable to any material type. A principal approach to total material quality control was conceptualized, defining the two main necessary components and steps for data specification, acquisition, and exchange. Two main components were identified: (1) the combined physical and digital identification and traceability solution, and (2) the essential information needed for circular material traceability. The traceability solution (1) aligns with the EU’s DPP concept: each material sample receives a unique digital ID, either for a distinct material object or as a reference to a larger batch. Each object—e.g., a package of pellets or a single component—is physically marked, such as with a QR code, or identified by statistically significant property measurements enabling batch or category identification (outside the DPP scope). To determine the essential information (2), a model was developed based on industry practices. It analyzed how companies secure material properties for products, beginning with specification of key properties—chemical, physical, mechanical—as well as quality indicators such as chemical purity and durability. These are typically defined via standardized analysis and test methods, implicitly requiring accredited laboratories. This is a central quality control aspect enabling trust in DPP data. Additional essential information includes environmental exposure—such as production, logistics, temperature, and mechanical stress—throughout the product’s life. This enables each material sample, batch, or component to carry data on optimal processing, use, sorting, EOL, and recycling, as well as its actual handling history. Such traceability is vital for circular material management and quality control, forming a kernel for a robust DPP. Associating material objects with their unique traceable data provides stakeholders with immediate insight into relevant material characteristics. Building on this conceptualization, a logical model was developed, followed by a strict relational model, which was then mapped to ISO 10303 standard application protocols AP242 and AP235. This preserves the data model and ensures end-to-end traceability of both virgin and recycled materials. Based on the generalized conceptual model, this approach is extendable to any material or product category. AP242 is widely used in mechanical design (3D CAD) with embedded manufacturing data. The adoption of STEP standards enhances model robustness and compatibility across all product lifecycle phases: ’as designed’, ’as manufactured’, ’as tested’, ’as recycled’, ’as disposed’, and ‘as reused’. Thus, the conceptual model for ABS plastics traceability and quality control developed in ABSolEU is generalized into a solution for circular traceability and material quality control, potentially serving as a compliant module within the European digital product passport framework.

The Initiative MaterialDigital was launched to enable and support a joint effort of MSE specialists from different materials domains and experts in semantic web technologies, scientific workflows and IT architecture to explore and find the best digitalisation approaches for materials data handling according to the FAIR (Findable, Accessible, Interoperable, and Reusable) principles. The MaterialDigital (PMD) platform aims to provide prototypical solutions for all the processes involved, including data acquisition, structuring, storage and processing. These different aspects are addressed within the platform’s focus areas of IT architecture, semantic interoperability and workflows, and disseminated through the focus area community interaction working group. Achieving semantic interoperability of material data across different material domains in an industrial data space is the fundamental goal of the initiative. The MaterialDigital projects cover a wide range of material domains in their research, from steel and copper to ceramics, semiconductors and rubber. This ensures that the digitalisation approaches developed in the platform can be applied to any MSE challenge. The platform also actively connects to other related national, European and international activities such as NFDI, Gaia-X or the DPP.

The results will be used to revise and recalibrate outdated models used to derive composite structure mechanical properties. Updating those models will allow us to more accurately predict the fatigue lifetimes of critical composite structures such as aerofoils used in wind turbines and jet engines. Test datasets are generated and provided bymultiple partners, each using their own customary way-of-working. Collecting datasets in various formats, massaging them into a uniform, standardized format, and managing the data in a consistent, traceable fashion, has been a major project challenge. Additionally, we have made pertinent contributions to the CHADA v2 standard, and recently presented our data processing and management journey as part of the EMMC’25 conference. Several challenges have included: •Ensuring that metadata from different lab tests are recorded and preserved with uniform structure and quality; •Making those metadata searchable in an effective, efficient, and useful way; •Ensuring that source data can be consistently and reliably stored, discovered, accessed, and retrieved; •Coupling materials characterization metadata into the EMMO ontology In addition the DPP endeavours to include LCA data in order to aid reuse and recycling of composites. 1Royal Netherlands Aerospace Centre (NLR) Keywords: Composite Materials, Digital Product Passport (DPP), Life Cycle Assessment (LCA), Aerospace, Wind Energy, Sustainability, Circular Economy, Data Standardization, Material Characterization, EMMO Ontology, EU Regulation Page 52 ID: 505 Time: 17:40Title: Digital Material and Product Passports: Advancing SSbD in the PINK Project Project Reference: PINK (Horizon Europe, Grant agreement No. 101137809) Thomas Exner Seven Past Nine [email protected] Abstract: To achieve the goals of the European Green Deal and the new Clean Industrial Deal, advanced materials and chemicals are needed to provide new or improved functionalities and, at the same time, be both safe and sustainable. These materials need to be developed following the Safe-and-Sustainable-by-Design (SSbD) paradigm. There is consensus that covering the demand across all material innovation markets is only possible by heavily relying on digital approaches for data collection, sharing, and gap filling. It is also essential that all stakeholders, starting with raw material providers, materials designers, integrators, distributors, waste managers, and recyclers, are integrated into the process of creating realistic views on material and product life cycles and complex, interlinked, and partly circular value chains. Additionally, all the required data must be collected for the holistic assessment needed for SSbD. The PINK project is currently designing and implementing major components for a technical and semantic Interoperability Framework to integrate data from all SSbD dimensions and stakeholders into a federated data system. These components are meant to be further generalized and made publicly available for adoption by other projects as part of a European digital material ecosystem. However, supporting all stakeholders is not only a question of data and tool availability. They also need to be interoperable and trustworthy. Data and tools from different providers must work together, and the results must be understandable and demonstrate accuracy and confidence to allow informed decisions. Digital material and product passports could play a key role here, as they could become a harmonized and trusted source for sharing SSbD data with clear provenance trails. This presentation will elaborate on the benefits of integrating additional SSbD criteria in digital passports and utilizing these passports for data sharing along the value chain.

This is a four-year project funded under the Horizon EU call HORIZONCL4-2024-RESILIENCE-01-08 which started in October 2024. The project partners cover the entire REE value chain starting from mineral exploration, through mineral processing, recovering rare earths from side streams and refining to metal production and magnet making as well as recycling. The project incorporates a safe and sustainable by design framework including design for Re-X (recycling, reuse, refurbishment, repurposing, reduction of HREE and REE) approach integrating easy dismantling and circularity properties. The Re-X technologies for rare earths and valuable metals will be developed, along with electric machine designs that facilitate permanent magnet recycling. The design framework towards digital passport formation will follow the development procedure by: •Improving recyclability by design: The new electric machine design concept will follow the scalability and Design to Re-X aspects governed by digital twins, with minimal rare materials and high specific power density, allowing easy dismantling and using only a fraction of the energy currently needed for magnet extraction. For existing machines, energy-optimized dismantling processes will be developed. •Geo-based traceability: Primary REE production chains will utilize geochemical and isotopic signatures to track raw material origin and associated sustainability data. A coding system will make this info accessible across the supply chain. •Digital twinning and digital passport: an over-the-life cycle digitalised REE closed chain will be introduced, from different material sourcing via novel production process to guarantee optimal choices in different phases of the REE cycle. The digital twins will enable reducing and optimising the overall energy usage as well as to minimise the emission pollution. Permanent magnet (PM) digital passport in form of QR code will contain properties and chemical composition (list and amount of REE material inside the magnets) with their dismantling procedure, realising all aspects of Re-X approach after magnets’ end-of-life. By introducing the permanent magnet digital passport, we are introducing safe and sustainable usage of chemicals and materials from the early stages of innovation and along their entire life cycle This approach introduces a safe and sustainable usage framework for chemicals and materials throughout their entire life cycle.

Digital Product Passports (DPPs) are emerging as a foundational tool to support this transformation by providing accessible, structured, and dynamic product information throughout a product’s lifecycle. SMARTChain, an EU-funded Horizon Europe project, is developing and piloting dynamic DPPs in collaboration with industrial actors across the steel, automotive, consumer goods, and machinery sectors. These passports enable end-to-end traceability, improved product quality, and more sustainable decision-making, aligning with upcoming requirements from regulatory frameworks such as the Ecodesign for Sustainable Products Regulation [2]. The project also focuses on building an Industrial Data Space to ensure secure and interoperable data exchange across the value chain—from steelmakers to steel users. Pilot activities are being carried out with a group of high-profile industrial partners, to test DPP solutions in real operational environments. These pilots demonstrate how data on material properties, production processes, and environmental performance can drive circularity, improve collaboration, and unlock new value for both manufacturers and end-users. This work will explore the enabling role of interoperable digital infrastructure and highlight how DPPs can lay the groundwork for a more circular, transparent, and data-informed industrial future.

For example, eco-advance from the German Federal Ministry for the Environment. Ana Gabriela Vergara United Nations Environment Programme [email protected] Abstract: The Digital Product Information Systems (DPIS) Global Framework represents an overarching vision to harmonize product sustainability data systems globally. It sets out the guidelines and principles that will steer the development, implementation, and harmonization of DPIS across diverse industries and regions. Key objectives of the framework include achieving global consensus on the data categories of DPIS, promoting the adoption of high-level principles on data governance and technology architecture aligned with the Global Environmental Data Strategy. It champions the sustainability priorities of the Global South, ensuring that DPIS are designed to serve environmental and development goals equitably across all regions. The framework also recommends the adoption of financial mechanisms and capacity-building strategies for the implementation of DPIS, ensuring that these systems benefit all countries without creating trade barriers. Core principles guiding the framework include inclusion and stakeholder centricity, which prioritize regional adaptability and accessibility, particularly for SMEs and actors in the Global South. The framework also promotes interoperability across diverse systems without mandating specific technologies. With a sector-agnostic approach, it ensures applicability across industries and facilitates the smooth exchange of sustainability data worldwide. Through systems thinking, it acknowledges the complexities of global value chains and emphasizes the interconnectedness of stakeholders, regions, and data flows. Adopting this framework will reduce trade barriers, increase inclusivity, enhance efficiency, and improve scalability. It minimizes redundancy in data exchange, harmonizes efforts across regions, and fosters transparent value chains, ultimately contributing to the widespread adoption of sustainable practices and advancing global sustainability goals.

Chairs: Franz Pirker, Stella Georgali This session will explore the business potential of DPPs, focusing on their value in digital platforms, open innovation strategies, and sustainable business models across multiple industries. The EU 27 contributes only 4 percentage of global capital investment in the digital economy, in strong contrast to the United States’ 74 percentage, dominated by major players like Google, Apple, etc. This disparity reflects Europe’s untapped potential, stemming largely from widespread misconceptions about digitalisation. Digitalisation extends far beyond data spaces, software development, ontologies, or digital twins; it is fundamentally about leveraging digital technologies to redefine business models, unlock new revenue streams, and create value. According to Gartner, “Digitalisation is the use of digital technologies to change a business model and provide new revenue and valueproducing opportunities; it is the process of moving to a digital business.” ID: 701 Time: 13:20Title: A large scale DPP initiative in France and in Europe Project Reference: A collaboration between the CE-RISE and CircThread projects Xavier Lantoinette WEEE Forum a.i.s.b.l. [email protected] Abstract: This pilot is led by Ecosystem, a French Producer Responsibility Organization (PRO), with support from the WEEE Forum and the Circular Intelligence Association. It involves manufacturers, retailers, and repairers, with the goal of tracing approximately two million appliances over a two-year period, tracking their lifecycle stages from manufacturing to reuse, repair, and recycling. Key aspects of the project include: •Openness to all stakeholders, including manufacturers, retailers, repairers, and recyclers, ensuring broad participation. •Rapid pilot launch with a limited number of initial stakeholders and gradual expansion. •The use of non-proprietary blockchain technology to facilitate data sharing and governance among participants. •A dedicated working group responsible for the governance of the data and platform. The pilot will track the environmental performance of the solution by evaluating the avoided impacts of extending the product lifespan through repair, reuse, and remanufacture. The project began in October 2024, and the first DPPs were created just a few weeks ago. Initial participating companies include BEKO (Producer), DARTY (Retailer, Producer, and Re-pairer), and ENVIE (Repairer, Reuse, and Remanufacturer). GS1 France is also involved, with discussions underway to bring in more producers and retailers. The initiative aligns with the EU’s Ecodesign for Sustainable Products Regulation (ESPR) and seeks to demonstrate the value of collective deployment in scaling DPPs across the sector. Through this initiative, the project will contribute to the transparency, traceability, and circularity of products, fostering greater consumer trust in refurbished and reused products.

It‘s lead by Intesi group and msg. TRACE4EU designs and implement use cases on productand material traceability with clear focus on digital product passport using the European Blockchain Service Infrastructure (EBSI) and so strength European Digital Sovereignity. Technically TRACE4EU is based on EBSI and adds a Traceability Toolbox developed in the project as building block for European Companies and authorities. Practically we combine organizational wallets and identities concerning the new eIDAS Regulation with (qualified) attestation of attributes representing the DPPP and the evidence fior the supply chain (Traceability). The use case is e.g. Digital product Passport for batteries acc. to EU regulation. Means, every part of the product developed within the product life-cycle is made evident with single attestation of attributes issued by certain producer (or independent trust service) into the related wallet - the whole DPP is created within the supply chain - so that the one for full product contains the evidences for each component as a container which represents the DPP. Additionally to fulfil also the requirements on EU Regulation on Supply Chain TRACE4EU ensures that each step in the supply chain is track and traced as traceability event in EBSI and linked to the corresponding evidence (Attestations). Means the DPP makes also the supply chain evident to 3rd parties as each event can contain qualified timestamp and/or qualified seal acc. to eIDAS. With this combination of components coming from eIDAS so combination of digital identities, attestations and transactions using EBSI , the TRACE4EU project shows how the use of European Infrastructures with governmental trust anchor (as EBSI provided by EU member states), wallets and trust services shape core initiatives and regulations in the EU and strength European Digital Sovereignity. We aim to present the approach, challenges and solutions to the audience. This also includes how results from TRACE4EU are contributed to European & international standardization on DPP and eIDAS in CEN JTC 24, CEN JTC 19, ETSI and ISO to ensure international interoperability and provability.

In light of this, we propose the establishment of a cross-project working group to explore these questions collaboratively across EUand nationally funded initiatives. The working group would aim to develop a common understanding of high-impact circular strategies supported by DPPs in electronics, addressing challenges such as the trade-off between product durability and technological upgrade cycles, as well as the environmental footprint of components versus entire systems. A further objective would be the development of a simplified assessment approach to identify and prioritize promising use cases. Based on these insights, the group would also work towards policy recommendations concerning the data requirements of the DPP and additional regulatory needs, such as performance standards and liability considerations. The proposed working group seeks to create synergies across research efforts and contribute to the strategic alignment of DPP implementation with circular economy objectives.
