“…Viscosity is the property of rheology that defines the measure of the resistance to deformation. Rheology especially deals with the study of liquid and soft matter [20]. Because the viscosity of the oil is essential to the engine oil's primary functions, including wear control, friction reduction, and load carrying capacity, it must constantly be at an appropriate level.…”

In this research, ultrafiltration membrane made of Polyacrylonitrile (PAN) was employed to recover the lubricating oil from the waste oil in tandem with other treatment methods. FESEM was also used to analyze the structure of the membrane. The resultant recycled oil was monitored with Rheometer, FTIR and UV Spectrometer and it was found that the method successfully removed ˃90% of contaminants and heavy metals from the waste oil and improved the properties of the oil. The proposed method proved to be very economical and gave very promising results to reclaim the waste engine oil that can be re-used for various purposes. Also, the rheological behavior of engine oil is studied by a proposed mathematical model. Given that the suggested model was non-linear, the Gauss-Newton (GN) algorithm was employed to determine the ideal values for the model parameters. The experimental results obtained for virgin, waste and recycled lubricating oils from rheometer were used for validation of the model. The proposed model was compared with Reynold’s exponential model based on statistical methods (co-efficient of determination (R2) and mean square error (MSE)). It was found that that the proposed model can predict the change in viscosity with temperature with very high degree of accuracy (>99%).

“…Morris [176] described rheology as concerned with analysing how materials change or flow when the applied force is initiated, as process conditions in the barrel of the extruder are neither isobaric nor isothermal and are often dissimilar [177]. This rheological study is necessary because it relates to the overall characteristics of plastics, such as the melting and structure of the final generated product [178,179]. Since polyolefins (PP and PEs -high and low) constitute some of the highest percentages of plastics that are recycled due to their inherent properties, such as the ease of recycling and favourable chemical resistance, the need to optimise and model their reprocessing cannot be overemphasized [180].…”

Mechanical recycling of solid plastic wastes on a small-scale level can be accomplished with the correct approaches. Thermoplastics are mostly considered for mechanical recycling because of their physical properties and ease of reprocessing. This paper reviews the mechanical reprocessing techniques of selected thermoplastics (polyethylene terephthalate and polyolefins) since they constitute a significant proportion of plastics used commercially. Furthermore, necessary considerations for effective operation of small-scale plants, including energy requirements of machinery and optimisation in order to improve efficiency and product quality, are discussed. A clearer understanding and addressing of the process-related challenges will lead to successful establishment and management of small-scale mechanical recycling facilities to benefit communities. Efficient small-scale mechanical reprocessing establishments have become essential in reducing the environmental impacts of solid plastic wastes and for energy conservation.
