The main objective of the SOLRESS project is to propose an integrated biorefinery system to replace the chemical origin of some of the most widely used solvents in the industry, such as ethyl acetate, ethyl lactate and butyl acetate with a bio-based origin from second generation sugars from post-consumer coffee grounds and lignocellulosic feedstocks. The aim is to reinforce the integration of bio-based research and innovation throughout industrial bio-based systems. Moreover, in the valorisation process of these feedstocks, not only the cellulose fraction will be valorised, but also the hemicellulose fraction to obtain 2 of the most notorious green solvents of today, 2-MeTHF and GVL, from an additional line dedicated to the processing of furfural. The challenges will lie in improving downstream purification (DSP) processes and the techniques employed to achieve a technology that is efficient and cost-competitive with current chemical production systems for solvents. At the end of the project, all solvents will be validated in at least 3 of the most relevant applications (productive processes, formulations and recycling technologies) & at least 3 of the sectors with the greatest use of solvents (paints & coatings, cosmetics & materials processing) with the aim of evaluating its performance in comparison with its fossil-based counterparts, but also as a replacement for other dangerous and toxic solvents, such as NMP, CCL4, THF or toluene. Thus, the ambition of the SOLRESS project is triple: To replace the use of fossil, non-renewable raw materials with specific bio-based feedstocks in the production of some of the most widely used solvents. Offer SSbD alternatives to controversial solvents in terms of danger & toxicity (including the ones under the SVHC & SoCs categories). To improve the competitiveness of these processes by incorporating new methods & technologies that increase efficiency & sustainability, demonstrating their scalability & industrial applicability.

In order to maintain the leadership of the European aeronautics, the SuCoHS project will investigate potential weight and cost savings in expanding the use of composite materials in areas of demanding high thermal conditions (high temperature and fire). In particular, this project envisages new structural concepts with novel multi-material composites to provide high resistivity against thermal, mechanical and fire loading. These developments also cater for high production rates, providing a cost competitive manufacturing process at minimum material and energy consumption, while reducing the requirement for visual inspection or rework. New solutions for structural health monitoring are considered within the structures to enable condition-based maintenance taking into account actual loading and structural conditions. Instead of an isolated investigation of innovative technologies the project will develop an integrated framework for the adaption of these promising technologies to different aeronautic components to increase efficiency during design, manufacturing and operation. Three industrial use cases are defined from real industrial design challenges to set requirements, to validate new technologies and to demonstrate technical feasibility near to operation environment: a high temperature resistance nacelle component, a composite aircraft interior shell and a tail cone panel substructure. The SuCoHS project gathers 14 partners from 7 European countries, amongst which 2 technical universities, 3 research centers, 4 SMEs and 8 large companies. The requested EU funding amounts to 6 638 944 Euros for a 3-year project duration.
