A succesful design, deployment and operation of biometric systems depends highly on the results for existing biometrical technologies and components. These existing technologies as well as new solutions need to be evaluated on their performance. However it is often forgotten that the biometric (iris, finger, face e.g.) is only one part of a fully deployed application. As biometric (sub)systems are often not designed with security and or privacy in mind, system integrators will need to address the requirements of the deployed application in this light. The fears and concerns of a significant segment of the user population need to be addressed as early as possible in the design process, to ensure that appropriate mechanisms are in place to reassure such users. These concerns may relate to privacy or to safety issues, which may be adressed in part through legal and regulatory measures.

What are the circular possibilities for materials and productsavailable in the Griffiersveld pilot and how can this informationbe presented? Interviews with stakeholders have led to a list ofrequirements for the material passports and what informationthey should include. Existing and experimental materialpassports have been collected and analysed to see whetherthey meet the requirements. The construction materials on siteare identified and circular possibilities of these materials arelisted. Finally an advice is given for the municipality ofApeldoorn for a circular renovation approach.

CC-BY 4.0 In this report the research focusses on designing a method to circularly redesign a road in neigbourhood participation. Municipalities are becoming more aware of their environmental footprint. The construction andrenovation of public spaces come with the transport and processing of large volumes of concrete, clay bricks and asphalt. We are in the transition towards a circular economy. In the CityLoops project we propose the following composite definition for the circular economy, drawing on the work of different academics in the field.

The transition to a circular economy requires innovative digital solutions to extend the lifespan of electrical and electronic appliances (EEA) and reduce the volume of waste generated by this product stream. Digital Product Passports (DPPs) make product and usage information accessible to supply chain partners and serve as a crucial tool for optimising circular strategies. DPP data on performed maintenance, upgrades, (sensor) data on EEA usage, diagnostics and repairs support supply chain actors throughout the product lifecycle in carrying out their circular responsibilities. This project focuses on the application of DPPs in the "Middle-of-Life" phase of EEA products, specifically dishwashers and coffee machines. The central research question is: How can the EEA supply chain design and actively manage a DPP in a way that creates value for all stakeholders in the Middle-of-Life phase and contributes to product life extension and circularity? The applied methodology is based on Design Science Research (DSR) and Co-design, in which manufacturers, repair services, collection partners and DPP solution providers collaborate on a practice-oriented implementation. In co-design sessions, the requirements and functionalities of DPPs are defined based on identified circular roles and related information needs. These are then translated into a DPP "Proof of Concept", which is tested by partners across the electronics value chain. The intended outcome is an implemented and validated DPP concept that unlocks product data, optimises circular processes, and strengthens collaboration within the supply chain. This project contributes to strategic policy agendas on digitalisation and circularity and offers a blueprint for the broader application of DPPs in the EEA sector. The project partners – ATAG Benelux, E-Care, Beekman B.V., Holland Circulair, Eviden, Saxion University of Applied Sciences, and HU University of Applied Sciences Utrecht – combine their expertise to develop a future-proof, scalable and practice-based DPP solution.
The DPP4CD project, “Digital Product Passport(s) for Circular Denim: From Pilot to Practice,” focuses on delivering pilot and scalable Digital Product Passports (DPPs) in the circular denim industry. This aligns with the upcoming European Ecodesign for Sustainable Products Regulation (ESPR), making DPPs mandatory for textiles from 2027. A DPP for circular denim should clearly detail material composition, production methods, repair records, and recycling options to meet EU rules like ESPR, Corporate Sustainability Reporting Directive (CSRD) and European Sustainability Reporting Standards (ESRS). It combines dynamic lifecycle data into a standard, interoperable system that boosts traceability, cuts SME admin burdens, and supports sustainable, circular practices. Led by Saxion and HvA, the multidisciplinary project is based on a real-world Dutch use case with MUD Jeans, a leader in circular denim. The project combines circular economy principles with existing digital technologies, working with partners such as tex.tracer, Tejidos Royo, bAwear, Denim Deal, MODINT, EuFSI and, GS1 Netherlands. Instead of developing new tools, the project applies scalable technologies (augmented DPP extension) and methods e.g. blockchain, life cycle assessments, and traceability standards to denim supply chains. The project defines legal, environmental, technical, and user requirements for DPPs in circular denim and designs a modular, data-driven, and ESPR-compliant system that integrates offline and online components while ensuring interoperability, affordability, reliability, accountability, and scalability. It develops a data framework for material tracking, supported by interoperable digital solutions to improve data-sharing and transparency. A pilot DPP with MUD Jeans will cover the full lifecycle from production to recycling, enabling scalable DPP. The project aims to address societal challenges related to circularity, ensure scalable and implementable solutions, and create a digital platform where knowledge can be developed, shared, and utilised. By combining circular practices with digital technologies, DPP4CD will help textile businesses transition towards sustainable, transparent, and future-proof supply chains.
A major challenge in the textile sector is achieving true circularity while preventing fraud, including false sustainability claims and material mislabelling. The complexity of supply chains and outdated certification systems have resulted in a lack of accountability and transparency. This project addresses these issues by developing and implementing Digital Product Passports, integrated with digital trust mechanisms as verifiable credentials, to create a transparent, responsible, and accountable textile supply chain. The project traces the journey of a corporate fashion t-shirt from cotton sourcing in India to production and distribution in the Netherlands, ensuring full transparency and traceability. Its goal is to drive a shift towards a circular economy by fostering collaboration across the supply chain and empowering stakeholders, particularly Tiers 3 and 4 in the Global South. Schijvens Corporate Fashion leads the effort with regenerative cotton sourcing through Raddis®Cotton, utilising Aware™’s technology solution. Adopting a ‘Fibre-Forward’ approach, the consortium ensures traceability by integrating data from raw material sourcing to end-user. This approach benefits all stakeholders, from farmers to garment producers, by providing verifiable information on fibre origins, social conditions, and ecological impacts. By tracking each fibre and collecting direct data, the project removes the opacity that can undermine sustainability claims. The project enhances accountability and sustainability compliance by utilising decentralised technologies for product verification. Integrating digital identity wallets for individuals and organisations, secured with verifiable credentials, enhances trust and accountability, fostering circular economy practices. Rather than seeing DPPs as the end goal, the project views them as catalysts for systemic change. It prioritises continuous improvement, collaboration, and shared benefits, aiming to establish a regenerative circular economy. Through a practical toolkit, the project will help organisations and policymakers navigate DPP adoption, strengthening transparency and creating a scalable, inclusive system for supply chains across the Global South and -North.
