Aldibereko teknika biologikoen bitartezko lurzoru kutsatuen erremediazioa

Abstract

Anthropogenic activities led to the proliferation of polluted sites or potentially polluted sites around the world; including Basque Country. Technologies to remediate or clean these soils, mainly polluted by heavy metals or organic pollutants are diverse and of different nature. On the one hand, classic physicochemical remediation techniques can be found; with high yields and short application times; but, high costs and high ecological impacts. On the other hand, biological techniques could be found. These technologies are cheaper and more environmental-friendly; but, they require long application times. Among most used bioremediation technologies plant-based phytoremediation, worm based vermiremediation, and mibrobia based bioremediation (or bioaugmentation) can be found. This paper deals with the main features of these techniques and their applicability; both as single remediadion techniques or combined.
