Soil Remediation

Soil that has grown naturally is a scarce, non-renewable resource. It plays a decisive role in the material decomposition and conversion process in the ecosystem and acts as a complex filter system in groundwater recharge. Unstressed soil is therefore a crucial basis for life for flora, fauna and humans. It is also interesting from economic perspectives, because mineral resources and energy sources are stored here.


To date, strategies for land recycling for the purposes of "sustainable resource protection" have been directed at decontaminating contaminated soil and then using it in road construction or for recultivation of industrial and uncultivated land. However, implementation of the sustainability principle in the future must have as its goal the use of soil in an environmentally friendly manner only, without causing permanent damage.
The website includes projects whose findings on this topic deal with the comparative suitability of thermal, washing, extracting and biological decontamination processes for certain cases of damage, or that have determined restrictions on use of individual technologies or conducted cost/benefit analyses. There are also examples regarding the development and use of various research methods as well as of the formulation of risk assessments and decontamination concepts.

Project-Icon(Enhanced) Natural Attenuation als Sanierungsstrategie für die Mineralölraffinerie Schwedt
Das Projekt untersucht, inwiefern kontaminierter Boden und BTEX- sowie MKW belastetes Grundwasser durch (Enhanced) Natural Attenuation (chemische, biologische Selbstreinigungsprozesse) gereinigt werden kann. Es zeigt auf, welche Bedingungen für den Selbstreinigungsprozess besonders förderlich sind und konzipiert eine Sanierungsstrategie. Expand…

Project-IconAsh sediments for improving the water quality of mining lakes
As part of this project, the project partners examine the use of alkaline suspensions to improve water quality of sulphuric post-mining water bodies formed from the remainders of opencast mines with additional CO2-mineralisation. Following the cleaning-up of mining lakes, this allows to derive economic benefit of it, as well as to recycle ash sediments, and lignite filter ash from power plants. Expand…

Project-IconBilateral cooperation between the BMBF and the U.S. EPA; phase II: development and testing of monitoring standards for contaminated sites in the course of German/American cooperation for the clean-up of contaminated land
In the course of German-American cooperation, a number of practical supporting tools for the conduct of operations have been developed: guidelines which, on the German side, can be used to test the technical suitability of decontamination installations; recommendations for a German technical standard on the clean-up of contaminated sites (DETAD) and a procedural instruction for the development and monitoring of reinstated land.

Project-IconBiodegradation of hydrocarbons: microbiological degradation of residual oil fractions using fatty acid-modified amino acids – increase in bioavailability
The degradation of hydrocarbons in soils can be stimulated by the use of newly-developed surfactants. However, the reduction in the residual oil concentration achieved by this method is not sufficient for the thorough decontamination of soils. A combination of this method with other chemical and physical processes is therefore recommended. Expand…

Project-IconBiological degradation of chlorinated aromatics in solids
A microbiological soil clean-up process for the degradation of chlorinated hydrocarbons has been developed and tested on polychlorinated biphenyls, polychlorinated dibenzodioxins/furans and hexachlorocyclohexane. Although decontamination has proved to be difficult, it has been successfully achieved in some instances with the assistance of site-specific micro-organisms. Expand…

Project-IconBiological remediation of contaminated sites from industrial carbon chemistry: Humification of PAH: Metabolism of fungi
In trials using various fungi, a series of strains have been identified which would appear to be suitable for industrial use in soil clean-up processes. The application of these strains is associated with the clear stimulation of PAH degradation, which can be further enhanced by the addition of growth substrates. Expand…

Project-IconBiological remediation of contaminated sites: development of microbiological/adsorptive methods for in-situ decontamination
For in situ and on site treatment of PAH contaminated soils biotechnological methods were developed and applied. Several reactor types for biotreatment of contaminated soil were tested in order to estimate an optimum degree of PAH removal from different types of soil. For the treatment of silty soils a hydraulic fluidized bed reactor proved to be most suitable. Expand…

Project-IconBioremediation of carbo-chemical contaminations: Controlled humification of PAHs (Technological development and process optimisation, coordination)
The decontamination process developed for polycyclic aromatic hydrocarbons in polluted soils allows the technical exploitation of naturally-occurring humification processes for the removal of contaminants. By this method, polycyclic aromatic hydrocarbons are oxidised to form carbon dioxide and water. In practice, this method represents a sustainable and cost-effective clean-up technology. Expand…

Project-IconBioremediation of carbo-chemical contaminations: controlled humification of PAHs (Technological development)
Essential components for the conditioning of contaminated soil material have been developed for the application of the “controlled humification of PAHs” as a clean-up technology. Work undertaken for this project concluded with the completion of scheduled preparations for the experience-based testing of this technological development. Expand…

Project-IconBioremediation of soil -assessment of the long-term behaviour / remobilisation of bound contaminants (TNT and PAH)
The four simulated biological remediation techniques led irreversibly to the determination of polycyclic aromatic hydrocarbons and trinitrotoluol in the humus matrix. These results were determined in long-term experiments on a pilot scale, in order to ensure relevance in practice.
