Laboratory of Residues and Soils

The laboratory of solid waste and polluted soil has as main objectives:

  • to conduct research in the field of waste treatment and remediation of polluted soil in order to help advance the understanding of this environmental problem.
  • to offer technological solutions to the problems related to the management of solid waste, sludge and polluted soils, in the form of management studies, analysis and characterization of waste and soils, and treatability studies.

Professors and PhD students belong to the Chemical Engineering Department of UCLM, including ITQUIMA and other research centres or faculties in UCLM.

ELECTROBIOREMEDIATION OF POLLUTED SOIL (2010 – …)

The aim of this research line is to study in-situ treatments for the remediation of polluted soils trough the combination of biological technology (commonly named as bioremediation) and electrokinetics. The fundamentals of this technology are that electrokinetic transport processes into the soil, because of the application of a low voltage direct electric current, allow the mobility of water, pollutants, microorganisms and nutrients into the soil, and thus activating and improving the in-situ bioremediation process. The final objective of this technology is to be applied in reals situations such as the pollution caused by breaks of underground fuel storage deposits or pipes, that is very usual for instance in oil refineries or petrol stations. Some studies have been performed and published about electrobioremediation of Diesel hydrocarbons in soil (2010-2015) and currently it is under study the electrobioremediation of organochlorinated compounds such as herbicides. There are also some technological options under study, such as “biostimulation” (that is electrobiormediation where the soil already contains specialized native microorganisms for pollutant biodegradation) or “bioaugmentation” (that is, using external microorganisms added to the soil trough biological biobarriers). The conceptual summaries of such technologies are included in the following figures.

This research line is included in research projects developed by TEQUIMA Group in UCLM. It is helped by economical support from the Spanish National Research Programme (CTM2006-03314/TECNO, CTM2010-18833, CTM2013-46512-R). Currently there is a Doctoral Thesis under development and collaborations with the Helmholtz Centre for Environmental Research – UFZ, en Lepizig (Germany).
