In this study the ex-situ bioremediation of waste heavy residual oil fuel was examined.
Microbial consortium was isolated from the polluted site at Belgrade Heating Plants (Serbia) and was added to the projected biopile. The nutrients, aeration-periodic mixing was used during process. The biopile was inoculated and biostimulated for 150 days. As a result, the total petroleum hydrocarbons (TPH) decreased by approximately 80 times. Also, the content of humic acids increased which indicated
the beginning of pedogenesis phase – soil formation (soilification). Level of humic acids during process at the end is higher about 40%. Also, bioremediation microorganisms from the inorganic matrix (river sand) generate clay minerals (content increases by about 50%) which are characteristic of the soil. At the same time, due to the microbial generation of organic acids, the concentration of carbonate
minerals from sand (calcite and dolomite) decreases. All these indicators confirm the efficiency of... bioremediation and the simultaneous formation of man-made soil (MMS) as new resource for agriculture, landscaping and reforestation. The obtained soil was used for the stabilization of municipal waste as an overlay at this time. In conclusion: bioremediation that generates some useful geo-material
is a great example of a circular economy that is different from the usual ones (such as aluminum can and paper recycling).
