Mercedes obtained her PhD on Earth Science and the Environment in the Dept of Geology and Geochemistry, Autonomous University of Madrid (UAM), while she was appointed as a teaching assistant (2008-2013). During this period, she studied the attenuation of contaminants from landfill leachates through real underlying clayey substrata. Afterwards, Mercedes joined the Dept of Chemistry, in the Catholic University of Leuven (KU Leuven), where she worked on the recovery of critical metals from industrial process residues and from low ores by solvometallurgical solvent extraction and leaching (2014-2018). Her work also included the challenges of current analytical techniques to measure low concentrated elements in complex matrices. Currently, she is a Marie Curie Individual Fellow (Standard EF – 2016) working on High Attenuation Recycling Materials as sustainable barriers for waste disposal sites (HARM), in the Groundwater Protection and Restoration Group (GPRG), together with the Geotechnical Engineering Group (Geo) of the University of Sheffield, UK. Her interests range from the attenuation of metals in natural soils, to sorption and separation of metals to concentrate them and recover them with a three-fold objective: the supply of critical metals, the recycling of industrial waste and the remediation of soils.
Present research lines
Attenuation of landfill contaminants by compacted liners made of mixtures of non hazardous industrial process residues with clays. By controlling the key parameters to mimicking the real conditions, different scenarios are tested in both long time and distance scales, using geotechnical centrifuge modelling.
