“…Their study indicated that almost 92% of TPHs were removed from the soil at 360 days of incubation. Similar results were also reported by Fitri and colleagues [ 49 ], Shah and others [ 50 ], Hamza and colleagues [ 51 ], Ishrat [ 52 ], Mittal and coworkers [ 53 ], and Singh and others [ 54 ]. It is already known that petroleum waste contaminated soil is a hub of thousands of hydrocarbon-degrading genera.…”

Nano-bioremediation application is an ecologically and environmentally friendly technique to overcome the catastrophic situation in soil because of petroleum waste contamination. We evaluated the efficiency of oil-degrading bacterial consortium and silver nanoparticles (AgNPs) with or without fertilizer to remediate soils collected from petroleum waste contaminated oil fields. Physicochemical characteristics of control soil and petroleum contaminated soils were assessed. Four oil-degrading strains, namely Bacillus pumilus (KY010576), Exiguobacteriaum aurantiacum (KY010578), Lysinibacillus fusiformis (KY010586), and Pseudomonas putida (KX580766), were selected based on their in vitrohydrocarbon-degrading efficiency. In a lab experiment, contaminated soils were treated alone and with combined amendments of the bacterial consortium, AgNPs, and fertilizers (ammonium nitrate and diammonium phosphate). We detected the degradation rate of total petroleum hydrocarbons (TPHs) of the soil samples with GC-FID at different intervals of the incubation period (0, 5, 20, 60, 240 days). The bacterial population (CFU/g) was also monitored during the entire period of incubation. The results showed that 70% more TPH was degraded with a consortium with their sole application in 20 days of incubation. There was a positive correlation between TPH degradation and the 100-fold increase in bacterial population in contaminated soils. This study revealed that bacterial consortiums alone showed the maximum increase in the degradation of TPHs at 20 days. The application of nanoparticles and fertilizer has non-significant effects on the consortium degradation potential. Moreover, fertilizer alone or in combination with AgNPs and consortium slows the rate of degradation of TPHs over a short period. Still, it subsequently accelerates the rate of degradation of TPHs, and a negligible amount remains at the end of the incubation period.

“…Petroleum sludge is a thick and viscous combination of solid residue, waste oil products, hydrocarbons, and water, that is generated during the crude oil refining processes, storage, as well as vessel cleaning [ 23 , 24 , 25 ], and it is produced more than 6 million tons annually in China [ 26 , 27 ]. The main areas of producing petroleum sludge are crude oil storage vessels and the separation of water from oil [ 23 ].…”

Petroleum sludge is a waste product resulting from petroleum industries and it is a major source of environmental pollution. Therefore, developing strategies aimed at reducing its environmental impact and enhance cleaner production are crucial for environmental mortar. Response surface methodology (RSM) was used in designing the experimental work. The variables considered were the amount of petroleum sludge ash (PSA) in weight percent and the ratio of sodium silicate to sodium hydroxide, while the concentration of sodium hydroxide was kept constant in the production of geopolymer mortar cured at a temperature of 60 °C for 20 h. The effects of PSA on density, compressive strength, flexural strength, water absorption, drying shrinkage, morphology, and pore size distribution were investigated. The addition of PSA in the mortar enhanced the mechanical properties significantly at an early age and 28 days of curing. Thus, PSA could be used as a precursor material in the production of geopolymer mortar for green construction sustainability. This study aimed to investigate the influence of PSA in geopolymer mortar.

“…The effect of petroleum in the environment are enormous and has been extensively reviewed by several authors [2,3,4]. Asides from spills, petroleum processing and equipment maintenance processes also results in the creation of considerable amount of hazardous solid waste such as oily sludge [5,6,7] which are usually disposed into the environment treated or untreated. These oily sludges are thick viscous, pasty semisolid mixture made of sand (a mixture of clay, silica and oxides), sediment, hydrocarbon, oil, water and chemicals used in petroleum processing and vessel or equipment cleaning [5,7].…”

Oily sludge (OS) degrading potentials of single and consortium autochthonous bacterial population was carried out using standard analytical procedures. Three autochthonous bacterial species; Pseudomonas aeruginosa, Bacillus cibi and Bacillus subtilis were associated with the OS. The isolates exhibited varying OS utilizing and biosurfactant producing potentials. P. aeruginosa was the best OS utilizer while B. subtilis was the best biosurfactant producer (emulsification index of 15.6%). Degradation of the OS with single culture of the best OS utilizer (P. aeruginosa) and consortium of the best OS utilizer and best biosurfactant producer (B. subtilis) revealed that the consortium exhibited a remarkable potential to reduce the total petroleum concentration in the OS from 100.73 ppm to 41.39 ppm (58.91% degradation) as compared to 51.74 ppm (48.7% degradation) achieved by the single culture. The saturated fraction of the OS was the most susceptible to degradation followed by the aromatic faction while the NSO and asphaltene fraction were the least degraded. P. aeruginosa was able to reduce the saturated hydrocarbon content in the OS by 87.4% while a 95.5% reduction was recorded for the consortium. Similarly, the concentration of PAH in the OS was reduced from 27.94 ppm to 16.74 ppm by the single culture and 12.75 by the consortium. The potentials of these bacterial communities can be explored for broader use in remediating oily sludge contaminated soil as well as managing oily sludge waste in the oil and gas industry.
