AlSiCal will de-risk and develop from TRL 3 to TRL 5 the Aranda-Mastin technology under sustainability and efficiency principles. It will assess and quantify the techno-economic feasibility, the potential value creation for Europe, as well as the impact and risks of this technology upon three key sustainability pillars: economy, society and environment. AlSiCal will also set a roadmap for exploitation of the project results, to foster the later commercialization of the technology. Targeted dissemination and communication actions will contribute to increasing social and industrial engagement for developing innovative sustainable technologies for mineral processing. AlSiCal will be performed by a balanced team of R&D and industrial partners representing the whole value chain.
