“…The metal components, e.g., zinc, appear in the drained engine oil in the form of oxide or mixed phosphate/sulfate glass. While there are methods proposed and developed for removing hazardous elements from used engine oils, the removal of sulfur, phosphorus, and (heavy) metals poses challenges. If one considers the obtained chemical information on the carbonaceous matrix and (ZnO:P,S) nanoparticles with respect to the generally accepted suggestion of potential toxicity for soot particles, our approach allows us to predict nanoparticle-based hazards from mechanochemical applications.…”

Lubrication of an internal combustion engine is critical for energy and material losses. Engine lubricants contain a number of functional additives including zinc dialkyldithiophosphate, which is a commonly used antiwear additive that forms by in situ decomposition a protective interface at the metal surface. Here, we present a detailed nanoscale investigation of carbonaceous soot nanoparticles generated from real engine conditions. By combining macroscale XPS with high-resolution STEM-EELS-EDX, we reveal that such a soot nanoparticle matrix contains also 3–5 nm ZnO-based nanoparticles with additions of phosphorus and sulfur, originating from the organometallic antiwear additive. Under the consideration of the obtained chemical information on the carbonaceous matrix and (ZnO:P,S) nanoparticles and the generally known suggestion of potential toxicity for soot nanoparticles, our method allows us to predict nanoparticle-based hazards from mechanochemical applications and also their formation mechanism. These are critical information and also the basis of toxicity assessment, both for theoretical predictions and experimental testing for the estimation of overall life-cycle analysis, including the environmental impact. Our results unravel the tribofilm decomposition under real field conditions and hint toward potentially unidentified toxicological nanoparticle hazards with respect to organophosphate-containing lubricants.

“…Numerous researches have been undergoing particularly for recycling the waste lube oil [1]. Various surfactants have been intensively studied for evaluating their efficiencies for the treatment of used lube oil [7,8]. The waste lube oil spillage into the soil contaminates and leads to the water pollution and in long run clog the aquifers and contaminate the ground water [9].…”

The oily petroleum hydrocarbon discharge lead to the soil pollution, become harmful to both human being and the environment by long run. This present work is carried out systematically to evaluate the efficiency of Brij-35 for washing used lubricant oil. For this study, the soil and waste engine oil which was collected from local service station are characterized. The soil under study was categorized through soil gradient test. The permeability of the soil was also determined. The soil fraction which was obtained by sieving through mm sieve was used for the present analysis. All the characteristic properties of the soil and oil were tested by a prescribed method. The used lube oil density was 0.853 gm/cc at 15C. The interfacial tension of the oil under study was 52.1 mN/m. This important finding helpful in finding the solution for soil contamination by improper disposal of oily hydrocarbon wastes like waste lube oil.

“…Waste lubricating oil refers to the engine oil, transmission oil, hydraulic, and cutting oil after use. It is also referred to as the degradation of the fresh lubricating components that are contaminated by metals, ash, carbon residue, water, varnish, gums, and other contaminating materials, in addition to asphaltic compounds which result from the bearing surface of the engines (Riyanto et al, 2018). This waste engine oil may harm the environment when dumped into the ground or water streams, including sewers, resulting in soil and groundwater contamination (Udonne and Onwuma, 2014).…”

Recycling waste or crude lubricant oil is the best alternative to incineration. This article used the vacuum distillation method to recycle of waste lubricant oil. About 90% of lubricating oil was recovered from waste oil within the temperature range of 60-360 0C. Every measured property like density, viscosity, flash point, pour point, sulfur content, carbon residue, ash content, and water content were investigated and compared with fresh oil. Pour point was found not to improve through vacuum distillation but rather decreased. Similarly, vacuum distillation could not improve the viscosity and density of recycled material but rather decreased. Adding 2% EPDM, SPO ESPRENE V0141, and pellet form of rubber as additives increased those two properties significantly. Finally, 0.1% NaNO3 was also added as an antioxidant. So, lastly, it can be concluded that the vacuum distillation process can effectively recycle waste lubricant oil in an economical and environmentally friendly manner. J. Bangladesh Acad.
