Since 2004, Nuno Lapa is an Assistant Professor at the NOVA School of Science and Technology (FCT NOVA) of NOVA University Lisboa (NOVA). Currently, he develops teaching activities in the Department of Chemistry (DQ). Dr. Lapa is certified by the Portuguese Open University in Distance and Digital Teaching.Since 2014, he is an Integrated Researcher at the Associated Laboratory for Green Chemistry (LAQV-REQUIMTE) (https://laqv.requimte.pt/), which is funded by Fundação para a Ciência e a Tecnologia (Foundation for Science and Technology) of the Ministério da Ciência e Tecnologia (Ministry of Science and Technology). He holds a Ph.D. in Environmental Engineering (2004) from FCT NOVA in the field of eco-compatibility studies of new materials for civil engineering based on the reuse of bottom ashes from Municipal Solid Waste incineration plants. He is the author or co-author of over 118 national and international papers, books, and chapters in books that have been published since 1994. Dr. LAPA has an h-index of 23 with 1549 citations by 1355 documents and 150 co-authors (source: Scopus, on March 13, 2023).He is an Editorial Board Member of the scientific journal entitled Waste Management (Elsevier) (https://www.journals.elsevier.com/waste-management) (2021 IF: 8.816; 2020 CiteScore: 13.5)He is an External Expert of the Research Executive Agency and the European Innovation Council and SMEs Executive Agency (European Commission) and the National Agency for Innovation (ANI). His research activity is oriented to the chemical and ecotoxicological characterisation of biomass and wastes towards its reuse in new materials and valorisation for energy purposes. Expertise: 1. New strategies for the valorisation of organic and inorganic wastes as secondary raw materials towards a circular economy: (i) Production of biochars and activated carbons from organic biowastes. (ii) Use of biochars and activated carbons in wastewater treatment systems, recovery of metals, and gas flow treatment systems. 2. Environmental risk assessment of new materials derived from wastes through chemical and ecotoxicity methods. 3. Optimization of biological processes for the valorisation of organic wastes: (i) Enhancement of biogas production through anaerobic digestion. (ii) Production of biohydrogen through dark fermentation. 4. Sustainability assessment of new products and processes (Life Cycle Assessment, Carbon Footprint, Water Footprint, and Ecological Footprint).
