Soil Treatment

Soil contaminants are not always very well-known and clearly identifiable. Therefore, this type of decontamination activity requires a higher amount of commitment and technical expertise compared to other sectors. Differences in soil typologies and a diversified range of pollutants make this activity particularly challenging for the operators.

SetCar is a renowned expert in this field, utilising both indirect thermal desorption (ITD) and direct thermal desorption (DTD) methods.

SetCar’s laboratories are performing tests on the use of Grafysorber® for such activities, with the aim of proving that this technology is viable on an industrial scale.

Case History

Rehabilitation of historically polluted site – Romania

The project consisted in collecting and disposal of 250 tons of hazardous and non hazardous wastes, excavation of 64.000 m3 contaminated soil, sorting and washing treatment of 36.000 tons soil contaminated with Cr+6, As, Pb, heavy metals and chemical wastes; evacuation and treatment of 4.500 m3 contaminated resulted sludge; stabilisation/ solidification treatment of 75.000 tons of soil contaminated with Cr+6, As, Pb, heavy metals and chemical wastes; filling soil import, refilling, compaction, revegetation and monitoring.

GRAFYSORBER® for soil treatment

Given its exceptional absorbency against hydrocarbons, GRAFYSORBER® has also been tested in the laboratory for the decontamination of sands and soils, giving excellent results.
A pilot plant is under development to test the technology on real terrain.
