Ottavio R. D. R. Carmignano is graduated in Law (Faculdade Milton Campos, MG-Brazil, 1996) and has a master’s degree in Socioeconomic Environmental Sustainability from the Universidade Federal de Ouro Preto (UFOP, MG-Brazil, 2015). He is Manager Partner of Pedras Congonhas Ltda. since 1992. His research is based on new applications for serpentinite rock in industrial markets. Currently, he is a PhD student in innovation at the Universidade Federal de Minas Gerais (UFMG, MG-Brazil).

Sara S. Vieira is a professor of Chemistry at Universidade Federal Fluminense (Brazil) since 2021. She received her PhD (2014) in Science from Universidade Federal de Lavras (Brazil) in partnership with the Center of Structural Chemistry of Instituto Superior Técnico (IST) of the University of Lisbon (Portugal). She did a Post-Doc at UNIFAL-MG, Brazil (2014-2016) and in the Chemistry Department at UFMG, Brazil (2016- 2020), developing research involving the evaluation of potential adsorbents and catalysts based on mesoporous silicates, iron oxides, and mining residues. The studies mainly evaluated the applicability of these materials as catalysts for the production of biofuel and products of greater added value.

Ana Paula C. Teixeira is a professor of Chemistry at Universidade Federal de Minas Gerais (Brazil) since 2013. She received her PhD in Inorganic Chemistry at this same university. She did a Post-Doc at Rice University (Houston, TX, USA, 2019-2020) developing research in the area of carbon materials for environmental application in the group of professor P. M. Ajayan. Her research interests include carbon materials synthesis for environmental applications and the use of mineral waste for technological applications.

Fernando S. Lameiras is graduated in Physics from Universidade Federal de Minas Gerais (1976) with a Specialization in Nuclear Technology (UFMG/NUCLEBRÁS, 1978) and has a master’s degree in Nuclear Science and Techniques (UFMG, 1982), and PhD in Metallurgical and Mining Engineering (UFMG, 1991). He is a researcher at Centro de Desenvolvimento da Tecnologia Nuclear (CDTN) since 1977 and a professor at the Post-Graduate Program in Science and Technology of Radiation, Minerals, and Materials (master’s and doctorate). He works in the area of materials engineering (nuclear fuel, ceramic materials, gem processing). Since 2005 he has been involved in the use of mining tailings in Portland cement and alkali-activated materials.

Paulo Roberto G. Brandão is a Mining Engineer (Universidade Federal de Minas Gerais, 1968). He obtained master’s and PhD degrees from the University of British Columbia, Vancouver, Canada, in 1982. He is a professor of the Department of Mining Engineering at Universidade Federal de Minas Gerais. He retired in 2003 and was awarded the title of Professor Emeritus. His areas of interest include ores and industrial minerals characterization and processing; reagents for minerals processing; recycling of mineral wastes, aggregation, and dispersion of mineral slurries; ironmaking, ceramics, and refractories.

Rochel M. Lago is graduated from the University of Campinas (UNICAMP, São Paulo State, Brazil) with MSc under the supervision of Prof Ulf Schuchardt. In 1992, he spent one year at Gifu University (Japan) followed by a PhD at Oxford University (United Kingdom) under the supervision of Prof M. L. H. Green and a Post- Doc with Prof J. L. G Fierro at the Institute of Catalysis and Petrochemistry (Madrid, Spain) working always in the area of catalysis. In 2005, he went to the University of Montreal (Canada) as a Visiting Researcher at the laboratories of Prof Richard Martel to work with carbon nanotubes and a Post-Doc at the business school HEC (Heutes Etudes Commerciales, Canada) with Prof L. J. Filion on the theme of technological entrepreneurship. He works at the Department of Chemistry at Universidade Federal de Minas Gerais (UFMG, Minas Gerais State, Brazil) since 1997.
