This Environmental Microbiology and Biotechnology research group is the centre of environmental risk assessment and soil remediation in Hungary. Its reference works, in collaboration with various partners, include bioremediation (i.e. enhanced bioremediation with cyclodextrin) of several hydrocarbon contaminated sites, environmental risk assessment of the Gyöngyösoroszi sulphide ore mining site and development of a combined chemical and phytoremediation technology, environmental risk assessment of the Ajka red mud flood-affected area, development of cyclodextrin-based water treatment technologies, development of soil amelioration technologies with waste utilisation and development of landfill cover systems utilising suitable wastes.
