During an excursion to the soil treatment facility of the Bauer Resources GmbH we learned what can be done if prevention has failed and in-situ treatment of polluted soil is not an option – and at which cost.
See the image captions for details.
We meet with Dr. Uwe Schlenker of Bauer Resources GmbH and Dr. Axel Fischer (TU Dresden).
Dr. Schlenker, a CIPSEM alumnus, explains how a former pig farm has been transformed into a soil treatment facility.
He answers a long series of questions about how different kinds of soil pollutions can be treated in-situ and ex-situ, in this treatment facility.
After optimising our outfits towards maximising visibility and lowering the risk for spreading pollutants, we set out for a tour of the premises.
This is one of the halls in which soil bacteria are provided good conditions (through regulation of aeration and temperature as well as addition of nutrients) for multiplying and breaking down pollutants.
Activated carbon, mainly from coconut shells, is for example used to treat emissions from the ventilation system of the facility.
The soil is partially being processed by machines and techniques used in composting plants.
Some of the processing is also done outdoors, on a sealed surface. All the run-off from this area is being collected and treated.
Dr. Schlenker activates the installation which cleans the wheels of lorries leaving the treatment facility.
The treated soil can be used for construction, not for food production.
