Welcome to the personal webpage of Dr Mercedes Regadío-García ♀, where you can read about her research and other academic activities.


Mercedes Regadío is a Marie Curie Individual Fellow (Standard EF – 2016) on High Attenuation Recycling Materials as sustainable barriers for waste disposal sites (HARM), working in the Groundwater Protection and Restoration Group (GPRG), Dept of Civil and Structural Engineering (University of Sheffield, UK). 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 sorption of contaminants in landfill leachates through real 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 by solvometallurgical solvent extraction and leaching (2014-2018). Her interests range from the attenuation of metals in natural soils to immobilize them, 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 mixtures of clays with construction & demolition waste and/or biomass bottom ash. By controlling the key parameters to mimicking the real conditions, different scenarios are tested in both long time and distance scales.
