RISERS advances steadily toward creating a comprehensive IS Standardisation Roadmap through six key action lines: Action Line 1: Mapping the IS Standardisation Landscape: DIN reviewed ~800 international and European Technical Committees (TCs) for relevance to IS themes, visualized in an interactive diagram (image uploaded below). A stakeholder survey captured how TCs and practitioners address IS and identified unmet standardisation needs and barriers (image uploaded below). Action Line 2: Defining Priority IS Synergies and Resource Flows: Led by UGent, RISERS assessed 600+ IS synergies from databases (SCALER, AIDRES, EPOS, MAESTRI), compiling 300+ Materials, Energies, and Services streams by source and sink sectors. A Legal, Economic, Spatial, Technical, Social analysis shortlisted ~50 high-impact cases, followed by 'People, Planet, Profit' evaluation selecting the top 10 cross-sector synergies with greatest potential (image uploaded below). These synergies span sectors like steel, cement, chemicals, refineries, energy, bio-based industries, textiles, and batteries. They align with EU resilience and CE priorities, relevant to multiple sectors. This prioritisation grounds the Working Groups’ roadmap development in real-world, high-impact IS practices. Action Line 3: Stakeholder-Driven Co-Creation of the Roadmap via Thematic Working Groups (WGs). In 2025, RISERS launched ten WGs to co-create the Roadmap: seven sectoral groups (e.g. metals, batteries) and three horizontal groups on cross-cutting themes (e.g. end-of-waste, data exchange) (image uploaded below). Their work is informed by: Policy consultations (FhG and ISL) on regulatory bottlenecks like End-of-Waste criteria and by-product classifications; Interviews with policymakers (FhG) and IS practitioners (UGent) providing real-time technical and operational perspectives; Action Line 4: Aligning Technical and Policy Frameworks for IS RISERS prioritised aligning IS standardisation with evolving EU regulatory frameworks, especially the interplay between End-of-Waste (EoW) criteria and by-product definitions. Consultations with policymakers led to policy recommendations published June 2025, guiding the WGs. In-depth interviews captured diverse stakeholder insights on gaps, bottlenecks, and limitations in the IS standardisation landscape, informing the roadmap’s second phase. Action Line 5: Advancing Integration of R&I into Standardisation RISERS laid groundwork for translating IS R&I into standardisation through coordination with projects like Horizon Europe CORALIS, SYMBA, EURO-TITAN, LIAISE COST Action, TRILATE, and DEREMCO, exploring synergies. Action Line 6: Communication and Dissemination RISERS implemented a broad communication strategy, showcasing the project at 21 events and organising 11. It reached over 1,000 external participants and 300 project event attendees. 14 communication materials were published, a LinkedIn community grew beyond 300 followers, and the project website attracted 2,500+ unique visitors. These efforts foster an engaged IS standardisation community across Europe.
