The aim of this work was to study the biodegradation of different types of automotive lubricant oils adapted to the aqueous medium using a base inoculum and an aqueous inoculum. Four treatments were carried out in two consecutive and similar experiments: T1 (control); T2 (half-synthetic oil); T3 (mineral oil); T4 (used oil). The results showed the following decreasing order of CO2 production in the Bartha and Pramer respirometers: T4 > T2 > T3 > T1. Thus, the used lubricant oil showed with highest biodegradability, followed by the half-synthetic one and the mineral oil. It was also observed that the mineral lubricant presented a longer period of adaptation compared to the half-synthetic one.

Soil contamination with used lubricating oil from automobiles is a growing concern in many countries, especially in Asian. This research was conducted on a laboratory scale. The plant used in this research was Spathiphyllum spp. in comparison with controlled (no-plant). The size of reactor used in this research was set at 20 cm width, 20 cm length, and 40 cm height with working volume of the reactor was 0.016 cm3. Moreover, a pH value was controlled in a range of 7 to 8. The soil contaminated with used lubricant oil collected from automobile shop in Nonthaburi province. Soil contaminated and treated soil were extracted by solid-phase extraction (SPE) and analyzed by gas chromatography with mass spectrometer (GC–MS). The results showed that Spathiphyllum spp. could be growth during time operation. Spathiphyllum spp. has a potential in reclaiming hydrocarbon-contaminated soil such as Benzene, Toluene, Ethylbenzene, and Xylene (BTEX) approximately 20 to 60 days operation.

Used Lubricant Oil

Used Lubricant Oil (ULO) is a hazardous waste resulting from lubricant oil used in motorized equipment to reduce friction between moving surfaces that, over time, wear outs and becomes contaminated. The purpose of this study is to compare the sustainability of two ULO management systems in Brazil: one designated in this study by the TTR scenario (which includes transportation, trans-shipment, and re-refining phases), the other designated by the TsTR scenario (without the trans-shipment phase) to evaluate which scenario is socially, economically, and environmentally more efficient. The study uses the life cycle sustainability assessment (LCSA) methodology. As a combination of life cycle assessment (LCA), life cycle cost (LCC), and social life cycle assessment (s-LCA), it integrates the three sustainability dimensions (environmental, social, and economic). The sustainability index was calculated by aggregating data from eight environmental indicators, five economic indicators, and five social indicators. The results showed that the TsTR scenario presented the best values for the sustainability assessment than the TTR scenario. The TsTR scenario had the best social and economic performance, and the TTR scenario had the best environmental performance. The differences observed in those scenarios’ performances were noted by the absence or presence of the trans-shipment center. The absence of this center improved the social and economic performance of the scenario. The social dimension was improved by the elimination of the stage that causes problems related to social and economic dimensions by reducing several costs that can be associated with it. The presence of the trans-shipment center improves the environmental performance scenario by reducing the number of hazards that could impact the re-refining phase. The LCSA methodology enables a comparative life cycle assessment of two alternative system evaluations of ULO management by the sustainability index of each scenario. This index helps to analyze the contributions of each of the 18 categories and subcategories in the perspective of the sustainability dimensions and, consequently, to carry out their integrated evaluation, aiming to define the best sustainability scenario.

Used Lubricant Oil

The co-pyrolysis of used lubricant oil blended with plastic waste, namely high-density polyethylene (HDPE), polypropylene (PP), and polystyrene (PS), to produce a diesel-like fuel was studied. The proportions of the raw materials were optimized using laboratory scale pyrolysis at atmospheric pressure at a final temperature of 450 °C without a catalyst. The ratios of used lubricant oil (Oil) and plastic waste (Oil:HDPE:PP:PS) investigated were 50:30:20:0, 50:30:0:20, 50:0:30:20, and 50:30:10:10 by weight. It was found that the oil produced using an Oil:HDPE:PP:PS ratio of 50:30:20:0 exhibited most of the properties of standard diesel oil as specified by the Ministry of Energy (Thailand), except for its flash point, which was lower than the standard. Therefore, this proportion was utilized for the scaled-up testing in the co-pyrolysis prototype (10 kg/day). Three reactor temperature ranges (less than 400 °C, 400–425 °C, and 425–450 °C) were studied, and the properties of the oil products were analysed. The oil products produced at 400–425 °C exhibited diesel-like fuel properties.
