The project PILOT aims to develop two types of formulation technologies classes; a new UV hybrid varnish, which will combine the use of organic and silicone epoxy materials cured by the UV technology and a new hybrid solgel coating, where organic/silicone networks are reinforced by using colloidal particles of silica. Both technologies can be applied on a final paint scheme, but each of them has their particularities in terms of formulation, application and final properties. These differences will allow to cover a very large range of possibilities and will increase the chance of success of this project. The approach of the project is to get an efficient optically transparent multifunctional clear coat, which will able to protect the surface of the wings of business jet or HTP. While keeping the laminar flow, the technical solutions will have the capacity to: • Protect the substrate against contamination • Protect the substrate against icing formation • Resist to the erosion • Resist to the UV degradation • Dissipate the electrostatic charges • Be easily repaired To reach the target of the project, the consortium considers two different technologies, which have already shown their ability to match with Aerospatiale needs. For each approach, an existing solution has been selected. Several properties, according to the technical requirements, have been already tested. The project PILOT will fine tune them in order to fulfil the technical specifications. The project will start with a bibliographic study, whose objectives are to make a state of the art of the last updated technologies, a legislation survey, a screening of the commercial raw material in order to design the update formulations coatings. Then, based on the literature, the coatings will be formulated and applied on the required substrates, taking into account industrial constraints. Finally, coatings will be characterized to validate the required functionalities, defined in the topic.

The Green Deal sets up ambitious roadmaps for increasing EU sovereignty while promoting safer and more sustainable approaches. The SSbD framework published by JRC and adopted by the Commission proposes an approach to evaluate the safety, environmental, and socio/economic dimensions of molecules, materials and processes. The applicability of this framework is currently being tested under different typologies of products and maturity levels. PLANETS will demonstrate the applicability of the framework while technically developing alternatives for 3 of the most important classes of molecules in chemical industries (plasticizers, flame retardants and surfactants) at TRL 6 and their incorporation into broadly available consumer goods at TRL7. The new molecules and products will be significantly safer to workers and consumers and will have considerably lower environmental impact, while ensuring economic viability and social awareness throughout the 3 value chains (VC). PLANETS consortium brings together 18 complementary partners from 7 countries, including 8 large companies and 2 SMEs, covering the 3 complete VC, 5 RTO and the 3 non-profit organizations. These actors will bring the expertise required for all the project development: - Development of safer and more sustainable alternatives through SSbD assessments in a tiered approach. - Demonstration of the integration of the new molecules for the manufacturing of new products for various applications (coating, insulation foams and childcare articles). - Social and humanities sciences. - Business plans and market uptake approaches. - Digital Product Passport. - Identification of new skills and training. - Interactions with appropriate stakeholders and citizens and feedback to JRC and the EC. PLANETS ambitions are to strongly contribute to pave the road for the adoption of SSbD framework while proposing a roadmap towards industrialisation and market uptake of the alternative solutions.

Silicones, or polydiorganosiloxanes, are polymers having outstanding performances and great versatility in uses. During their synthesis, some cyclic oligosiloxanes are obtained by a retro-sission side reaction. The presence of these cyclic oligosiloxanes limits the application range of silicones. Taking these considerations into account, the aim of the project SILISCY is to develop new efficient catalysts, easily deactivable or removable that, associated to a specific polymerization process, would lead to the synthesis of silicones having a high degree of purity, without cyclic compounds. To achieve this objective, the SILISCY project is based on a multi-competencies team, located in Elkem Silicones France, LHFAteam in Toulouse, and IMP team in Lyon. The proposed methodology is fully described in the attached scientific file. The success of this project will lead to soft materials safe and robust, which will significantly enlarge the application range of silicones.

In the silicone value chain, from quartz to silicon then chlorosilane intermediates to silicone materials, the carbon impact of the upstream steps (silicon and intermediates) accounts for around 75% of emissions. An appealing recycling route consists of transforming waste silicone-based materials back to chlorosilanes. The direct cleavage of Si-O bond to form back Si-Cl is however very challenging. An indirect pathway has been elegantly discovered using BCl3 as an inorganic source of chloride. Nevertheless, this low temperature (< 60°C) catalytic route has a number of drawbacks (economical viability, access to BCl3, additional recycling loop of boron, etc.). The CARES project propose to address the much more challenging direct cleavage of Si-O bond to form back Si-Cl using all-silicon pathways (via SiCl4 and MeSiCl3 as chloride source). To face this significant reactivity challenge the use of catalysis is mandatory and the CARES project brings two academic laboratory CP2M and IRCE with complementary expertises in homogenous and heterogeneous catalysis and an industrial company Elkem covering the complete value chain from quartz to silicone materials.

Improving the life quality of Europe’s increasingly elderly population is one of the most pressing challenges our society faces today. The need to treat age-related degenerative changes in e.g. articular joints or dental implants will boost the market opportunities for tissue regeneration products like biological scaffolds. State of the art 3D printing technologies can provide biocompatible implants with the right macroscopic shape to fit a patient-specific tissue defect. However, for a real functionality, there is a need for new biomaterials, technologies and processes that additionally allow the fabrication of a scaffold microstructure that induces tissue-specific regeneration. It is not possible to address the complexity in structure and properties of human tissues with a single material or fabrication technique. Besides, there are many types of tissue in the human body, each with their own internal structures and functions. INKplant vision is the fusion/combination of different biomaterials (6 different inks), high-resolution, high throughput additive manufacturing technologies already proved for industrial processes (ceramic sterolithography and 3D multimaterial inkjet printing), and advanced simulation and biological evaluation, to bring a new concept for the design and fabrication of biomimetic scaffolds (3D printed patient specific resorbable cell-free implants) which can address the complexity of the different tissue in the human body, demonstrated for 2 Use Cases. For a successful future translation, INKplant will consider all the relevant clinical adoption criteria already at the beginning of the development process. To address INKplant challenging objective the consortium includes the best expertise from the main areas of relevance to the project: biomaterials, 3D printing technology, tissue engineering, regulatory bodies and social humanities.
