“…On the one hand, surfactants would adsorb onto the oil-wet calcite surface as with nanofluids [ 45 , 46 , 47 ]. On the other hand, surfactants could solubilize heavy oil molecules—that is, some heavy oil components would be released from the mineral surface—which made the water-wet calcite surface exposed [ 48 , 49 ].…”

In recent years, unconventional oils have shown a huge potential for exploitation. Abundant reserves of carbonate asphalt rocks with a high oil content have been found; however, heavy oil and carbonate minerals have a high interaction force, which makes oil-solid separation difficult when using traditional methods. Although previous studies have used nanofluids or surfactant alone to enhance oil recovery, the minerals were sandstones. For carbonate asphalt rocks, there is little research on the synergistic effect of nanofluids and surfactants on heavy oil recovery by hot-water-based extraction. In this study, we used nanofluids and surfactants to enhance oil recovery from carbonate asphalt rocks synergistically based on the HWBE process. In order to explore the synergistic mechanism, the alterations of wettability due to the use of nanofluids and surfactants were studied. Nanofluids alone could render the oil-wet calcite surface hydrophilic, and the resulting increase in hydrophilicity of calcite surfaces treated with different nanofluids followed the order of SiO2 > MgO > TiO2 > ZrO2 > γ-Al2O3. The concentration, salinity, and temperature of nanofluids influenced the oil-wet calcite wettability, and for SiO2 nanofluids, the optimal nanofluid concentration was 0.2 wt%; the optimal salinity was 3 wt%; and the contact angle decreased as the temperature increased. Furthermore, the use of surfactants alone made the oil-wet calcite surface more hydrophilic, according to the following order: sophorolipid (45.9°) > CTAB (49°) > rhamnolipid (53.4°) > TX-100 (58.4°) > SDS (67.5°). The elemental analysis along with AFM and SEM characterization showed that nanoparticles were adsorbed onto the mineral surface, resulting in greater hydrophilicity of the oil-wet calcite surface, and the roughness was related to the wettability. Surfactant molecules could aid in the release of heavy oil from the calcite surface, which exposes the uncovered calcite surface to its surroundings; additionally, some surfactants adsorbed onto the oil-wet calcite surface, and the combined role made the oil-wet calcite surface hydrophilic. In conclusion, the study showed that hybrid nanofluids showed a better effect on wettability alteration, and the use of nanofluids and surfactants together resulted in synergistic alteration of oil-wet calcite surface wettability.

“…Our previous study also reported that the composting process using yard waste and rumen residue increases the degradation of petroleum hydrocarbons in crude oilpolluted soil by 31 times compared to untreated soil over 120 days (Sari et al, 2019). It might be supported by in-situ bio-based surfactants which are formed during composting process (Kulikowska et al, 2015;Sari et al, 2018c).…”

“…According to Li The reduction of solubilized hydrocarbon levels was caused by the inhibition of in-situ biobased surfactant formation due to nutrient depletion of SW during the composting process, indicated by C/N ratio from 34.30 to 17.01 (Sari et al, 2019). In the 40 th to 60 th day-period of cHAL formation, there was strongly suggested that cHAL had become humin increase (Kulikowska et al, 2015;Sari et al, 2018c).

“…In-situ bio-based surfactants are divided into compost humic acid like substances (cHAL) and biosurfactants which are formed during organic waste decomposition by many indigenous bacteria in composting process. Our previous study reported that cHAL obtained from crude oil-polluted soil composting process using yard waste and rumen residue on day 40 th was able to solubilize petroleum hydrocarbons and reduce surface tension by 10,621 μg g -1 and 21.65 mN m -1 , respectively (Sari et al, 2018c).

Bacterial co-metabolism in composting process has been widely used to remove hydrocarbons, aided by in-situ production of bio-based surfactants, in terms of compost humic acid-like substances and biosurfactants. The properties of compost humic acid-like substances have been shown in previous studies as potential surface tension reducers and emulsifiers for hydrocarbons. The current study aimed to analyze the properties of biosurfactant of surface tension decrease, emulsification activity, and hydrocarbon solubilization ability. Four indigenous bacteria consortia were isolated from composted materials of yard waste, rumen residue, crude oil-polluted soil, and the mixture of polluted soil with organic waste (1:1, w/w) at day 0 th , 20 th , 40 th , and 60 th . Organic waste consists of yard waste and rumen residue in the ratio of 1:1. The isolated indigenous bacteria consortia were incubated for 7 days in different media, i.e., organic waste extract, 6.00% of crude oil, and a mixture of organic waste extract with 6.00% crude oil. The results indicated that the surface tension decrease and emulsification activity of biosurfactants were 8.35-52.90 mN m -1 and 0.00-12.00%, respectively, which showed the potential as surface tension reducers with low emulsification activity. The higher hydrocarbon solubility was shown by the biosurfactant from the rumen residue (13 620 µg g -1 ) and the mixture (10 998 µg g -1 ) at day 40 th , which was comparable to 1.50% of Tween 80. The biosurfactants in the current research were produced with the same materials, process, and time as compost humic acid-like substances which acts as in-situ bio-based surfactants. The respective ability to solubilize hydrocarbon might be combined and estimated to be higher than Tween 80 of 24 329 µg g -1 and 21 619 µg g -1 for rumen residue and the mixture, respectively. Therefore, it was concluded that the best composition for in-situ bio-based surfactant production to assist the degradation of hydrocarbon through composting process is polluted soil with organic waste (1:1, w/w). The solubility of hydrocarbons can be increased without synthetic surfactants addition, but through providing nutrients to maintain in-situ bio-based surfactant production with intermittent addition of organic waste every 40 days. This method is expected to be an appropriate approach in composting development as a cost-effective sustainable bioremediation technique for polluted soil.
