This symposium, originally founded in 2013 by Universidade Nova de Lisboa, Universidad de Zaragoza and University of Yamaguchi, is conceived as an international forum for the dissemination and reinforcement of research collaboration among the participating institutions. Different institutions have been invited to participate in subsequent editions. University of Cantabria had the opportunity to participate in the 2nd and 5th edition, and we are honoured to organize the present 6th conference, that unfortunately, was forced to be celebrated remotely due to the COVID-19 global pandemic. This edition continues with the topics discussed in the previous symposium. Scientific topics are aligned with the 2030 Agenda for Sustainable Development, and aimed at the study of key-enabling technologies and processes to ensure a sustainable industry for the society of the future. As a novelty in this edition, the symposium will consist of two events that will take place in parallel: • Live online scientific seminars given by reputed experts in the field of Chemical Engineering and related complementary scientific areas. • Students workshop aimed at the dissemination of the research activities of PhD and MS candidates. A special seminar session has been included, devoted to the dissemination of research goals and collaborative outcomes of the X-MEM project (5th EIG-Concert Japan joint call on «Porous structured materials»), with a partnership composed of researchers from University of Cantabria (Spain), University of Yamaguchi (Japan), Atilim University (Turkey), Ege University (Turkey), Hacettepe University (Turkey) and Jerzy Haber Institute of Catalysis and Surface Chemistry (Poland).
