ABSTRACT:
Approximately 80000 tons of drilling waste is produced in Poland annually. This type of waste is relocated and deposited in waste neutralization plants or landfills. Eventually, it must be managed. Reuse of solid wastes might constitute a method of their utilization. The article investigates the use of drill cuttings, sewage sludge and sawdust for production of soil-like mixtures. The studies on evaluation of the possibility of economic application of soil-like materials were carried out. The assessment was conducted on the basis of metal content in soil-like materials and plants cultivated on substrates produced of soil-like materials. In accordance with the valid legal regulations, the concentration of metals in soil-like materials enables their application on class II soils, i.e. arable land. The concentration of heavy metals in the plants cultivated on the substrates produced with soil-like materials is low and does not exceed the concentration of metals determined in animal feeding standards.
