The rapid development and adoption of Artificial Intelligence (AI) and Machine Learning (ML) technologies have brought significant opportunities and challenges. While AI has the potential to revolutionise industries and improve lives, there are growing concerns related to privacy, security, fairness, transparency and the environmental footprint. The Olympics motto "Faster, Higher, Stronger" also applies to recent impressive AI advancements, but now is the time to update it to "Lighter, Clearer, Safer". We propose ACHILLES to build an efficient, compliant, and trustworthy AI ecosystem. At its core is an iterative development cycle inspired by clinical trials encompassing four modules. It begins with human-centric methodologies, followed by data-centric operations, model-centric strategies, and deployment-centric optimisations. It returns to human-centric approaches, focusing on explainability and model monitoring. This iterative cycle aims to enhance AI systems' performance, robustness and efficiency while ensuring they comply with the legal requirements and highest ethical standards. Another innovation is the development of an ML-driven Integrated Development Environment (IDE). The ACHILLES IDE will facilitate seamless integration between the iterative cycle's modules, enabling users to develop efficient, compliant, and trustworthy AI solutions more effectively and responsibly. The project aims to significantly impact European AI development, aligning with the region's guidelines and values. Through innovative techniques and methodologies based on the collaboration of a multidisciplinary team of 16 partners from 10 countries, ACHILLES will foster a strong AI ecosystem that respects privacy, security, and ethical principles across various sectors. By validating the results in real use cases (including healthcare, ID verification, content creation and pharmaceuticals), ACHILLES will showcase its practical applicability and potential for widespread adoption.

H4C Europe project will create a European Community of Practice (ECoP). It will provide a community, knowledge platform, and exchange structures that will help the existing and future hubs in creation, management, and growth, by overcoming barriers to IS/I-US/C. The ECoP is set up to be self-sustaining. 10 existing Hubs have committed to join as ECoP Founding Members. The ECoP will preserve the findings of IS/I-US/C research and innovation projects, especially those funded by the EC and member states. It will organize a continuous exchange of ideas and best practices and facilitate in-depth exchanges between experts to identify bottlenecks, evaluate the outcomes of related projects, and propose innovative approaches to overcome bottlenecks. Possible topics include the financing and operation of IS infrastructures, matching demand and supply in IS and I-US, sharing benefits, cross-border exchange of materials, water, and waste-water systems, regulatory issues in the use of secondary raw materials, the tension between re-use and use of waste as feedstock, to name a few. Digitalization is a transversal enabling aspect of IS/I-US/C and the usage of digital tools will be an important aspect of each expert group. In line with the call and to achieve its vision, the CSA will work along four axes: 1) Sustainable Community building and establishment of an IT knowledge platform as a tool, 2) Consolidation and creation of available knowledge by analysis of the state of the art, in-depth discussions of leading experts, and field trials of business models and financial strategies a.o. for large-scale demonstrators, 3) Development of a KPI toolkit for the assessment of the maturity of IS/I-US/C regional initiatives towards H4C and independent evaluation of H4Cs as candidates for lighthouse projects, as well as the elaboration of policy recommendations, 4) Promotion of the H4C concept, societal engagement, and policy recommendations.

SisAl Pilot aims to demonstrate a patented novel industrial process to produce silicon (Si, a critical raw material), enabling a shift from today’s carbothermic Submerged Arc Furnace (SAF) process to a far more environmentally and economically alternative: an aluminothermic reduction of quartz in slag that utilizes secondary raw materials such as aluminium (Al) scrap and dross, as replacements for carbon reductants used today. SisAl Pilot represents a path-breaking approach, and a strong contribution to “circularity” through industrial symbiosis where the Al industry will act as both a raw material supplier and end user to the Si industry. Across sectors, SisAl Pilot will give substantial reductions in material yield losses, enhanced valorisation of waste- and by-product streams, at a 3 X lower energy consumption and radically lower emissions of CO2 and harmful pollutants, at a considerably lower cost. The SisAl Pilot project brings together raw material provider (Erimsa), silicon and aluminium key actors (Wacker, Elkem, DOW, Silicor, SiQAl, Hydro, FRey, Befesa, MYTIL), SME´s/consultants/ equipment manufacturers (BNW, SIMTEC, WS and SBC) and research organisations (NTNU, RWTH, NTUA, ITMATI, SINTEF, HZDR, MINTEK) to demonstrate the SisAl process with different raw materials and product outputs in 4 different countries. These pilots will be accompanied by environmental, economic and technological benchmarking, and industrial business cases will be assessed for locations in Norway, Iceland, Germany, Spain and Greece. The timing of SisAl Pilot is impeccable; the transformation to a circular economy, the strongly enhanced focus on climate and future expected EU-ETS CO2 allowances with associated risk for carbon leakage from Europe, the rapidly increased difficulty of exporting aluminium scrap from Europe to China, and modern society’s ever-increasing need for silicon metal. With SisAl, all these challenges are turned into new European opportunities.
