The First Conference on “Sustainable Zeolites: Advances in Synthesis and Applications” took place at the campus of Instituto de Ciencias de la Construcción Eduardo Torroja (IETcc-CSIC) in Madrid, Spain. The full-day event was part of the dissemination activities of the Z-ONA4LIFE project, which aims to show, on a pilot scale, that making synthetic zeolite is a practical and cost-effective technology to advance aluminium circular foundries. Organised by Z-ONA4LIFE project coordinator, Grupo Medes (IETcc-CSIC), in collaboration with Trust-IT Services, the event provided a platform for researchers, scientists and industry professionals to share and exchange knowledge on the latest advancements being made in the field of zeolites and spotlight the alternative research efforts being made to achieve cleaner and more sustainable processes for the production of zeolites.
