    Recycling of Waste Cooking Oil into Multifunctional Additives for Lubricants
    (Library Information Services COMSATS University Islamabad Lahore Campus, 2021-02-25) Muhammad Sikandar; SP20-R06-016; Dr. Muhammad Javid Iqbal; LHR TP 7570
    The recycling of waste cooking oils has been focused to build up cost-effective and multifunctional additives. Edible oils are most commonly used in kitchen as well as commercially. Animal fats and vegetable oils are the different sources used worldwide to collect edible oils. Vegetable oil utilization in 2019 has arrived at 204.88 million metric tons and this figure is expanding at a speed of 2% every year. Out of the absolute utilization just 20-30% is reused and when user discarded WCO, it causes problems for the environment and human health ultimately. It is recommended that WCOs can be used as helpful wellsprings of synthetic substances for the creation of bio plasticizers. In view of this, there is a need to develop technique / method to remove these harmful substances as well as to reuse the waste cooking oil as useful lubricant to fabricate multifunctional additives. To get this, we have used toluene as a solvent, Stearyl methacrylate polymer as well as palm oil as waste cooking oil. By using different molar concentration of above mentioned materials, different properties such as viscosity, viscosity index, pour point and flash point of synthesized additives has been investigated. Enhanced impact of above mentioned properties has been observed in the synthesized additives. Their physico-chemical properties has been assessed by different techniques.
