O desenvolvimento do Passaporte Digital de Produto (PDP), no âmbito da Agenda Mobilizadora "Ecocerâmica e Cristalaria de Portugal" (Agenda ECP) do PRR, resulta da colaboração entre a APICER e o INOV, focada na transição digital e verde do setor cerâmico nacional. O PDP é uma ferramenta que permite recolher e transmitir informação ao longo do ciclo de vida do produto e da cadeia de valor, incluindo dados de impacte ambiental, requisitos de ecodesign e circularidade. A arquitetura técnica, desenvolvida pelo INOV, baseia-se numa plataforma de interoperabilidade com modelo de dados extensível e normalizado, suportado por modelos semânticos que asseguram integração com diferentes sistemas. Inclui mapeamento para ambientes IFC/bSDD, permitindo ligação aos Product Data Templates (PDT) no BIM, bem como APIs, protocolos abertos de comunicação máquina a máquina e mecanismos robustos de autenticação e autorização. O sistema está alinhado com as normas em desenvolvimento pela CEN/CENELEC/JTC 24, com participação da APICER e do INOV via CT 228 do IPQ, e cumpre o quadro regulatório europeu, nomeadamente os Regulamentos (UE) 2024/1781 e 2024/3110. Os resultados incluem protótipos funcionais validados, permitindo testar fluxos de dados entre fabricantes e plataformas, contribuindo para maior competitividade, sustentabilidade e transparência da informação do produto.

This paper presents the design and validation of the ResourceNet platform, a digital solution with an architecture developed to support the circular economy by valorizing ceramic waste as Secondary Raw Materials (SRMs). Aligned with the EU Circular Economy Action Plan and the Waste Declassification Framework, the platform addresses the logistical and compliance challenges faced by SMEs in remote regions by facilitating the structured exchange of SRM data via an omnichannel digital marketplace. The proposed architecture integrates formal visual modeling techniques and complies with existing standards to ensure transparency, modularity, and traceability. The research adopts a Process-Driven Architecture (PDA) approach, complemented by a Model-Driven Architecture (MDA), to model the digital logistics of the SRM supply chain. The methodology utilizes BPMN and UML to map business workflows, data interactions, and system behavior. A context diagram anchors the architectural views, supporting alignment between stakeholder concerns and system capabilities. The findings, validated through a case study in the ceramics sector, demonstrate that integrating PDA and MDA enables an interoperable, standards-based platform that supports waste declassification, facilitates SRM traceability, and fosters industrial symbiosis. This positions ResourceNet and the corresponding lessons learned as a scalable solution for advancing digital circular economy ecosystems.

This paper presents ResourceNet, a modular web-based digital infrastructure designed to accelerate the transformation of ceramic waste into Secondary Raw Materials (SRMs), contributing directly to the achievement of circular economy (CE) objectives in the ceramics sector. Addressing the recycling dimension, the platform supports structured waste collection, classification, and traceable logistics through an omnichannel digital marketplace that connects waste producers, processors, and end-users. Its architecture is grounded in formal modelling and internationally recognised data and process standards, forming a composable service ecosystem that ensures SRM exchange integrity and lifecycle traceability. To address the disposal dimension, ResourceNet embeds compliance with waste declassification policies and integrates with downstream treatment operations (e.g., pre-treatment or heat-based processing). By bridging upstream collection and downstream processing, it promotes landfill diversion and enables more sustainable waste management pathways. From a synergy perspective, the design integrates Process-Driven Architecture (PDA) and Model-Driven Architecture (MDA) to align stakeholder concerns with system functionalities, enhancing interoperability and cross-enterprise collaboration. Modelling techniques (BPMN for processes, UML for data and behavior) support lifecycle material flow tracking and promote industrial symbiosis, particularly in resource-scarce regions. A sectoral case study validates how PDA-MDA integration fosters traceability and underpins circular valorisation pathways across industrial domains.
