Ex situ Bioremediation as Circular Economy: Microbial Mineralization of Waste Heavy Rezidual Oil Fuel (Mazut) From Belgrade (Serbia) Power Plants and its Reuse for Landfill Stabilization

In our work we have studied the process of bioremediation of waste heavy residual oil fuel (mazut) from the site of the Belgrade heating plants. Bioremediation is performed on the projected biopile adding microbial consortium that was isolated from the pollutet site. We added nutrients (biostimulation) at biopile, and aeration is provided by periodic mixing. Biostimulation and inoculation of biopile for 150 days resulted in a decrease of total petroleum hydrocarbons (TPH) for about 80 times and increased content of humic acids that indicate the beginning of Soilification. This "primitive" soil was used as an overlay for the stabilization of municipal waste landfill after bioremediation. Poster: [https://cer.ihtm.bg.ac.rs/handle/123456789/5470]
