Nuno Lapa has been an Assistant Professor at the NOVA School of Science and Technology (NOVA) of NOVA University Lisbon (NOVA) since 2004. Since January 2014, he has served as an Integrated Researcher within the Associated Laboratory for Green Chemistry - Clean Technologies and Processes (LAQV) - REQUIMTE network. Dr. Lapa's current research activities encompass several key areas: 1. Developing innovative strategies for the valorization of organic and inorganic wastes towards a Circular Economy: (i) Production of biochars and nanocarbon materials from organic biowastes. (ii) Utilization of biochars and nanocarbon materials in wastewater treatment, metal recovery, and industrial gas flows. 2. Conducting environmental risk assessments of new materials derived from wastes using chemical and ecotoxicity methods. 3. Optimizing biological processes for organic waste valorization: (i) Enhancing biogas and biomethane production via anaerobic digestion. (ii) Optimizing biohydrogen production through dark fermentation. 4. Assessing the sustainability of new products and processes using the Life Cycle Assessment, Carbon Footprint, and Life Cycle Costing. He holds an h-index of 26, with 2012 citations across 1773 documents and collaborating with 178 co-authors (source: Scopus, January 21, 2025).
