A detailed review was conducted to explore waste cooking oil (WCO) as feedstock for biodiesel. The manuscript highlights the impact on health while using used and scope revenue generation from WCO. Up a 20% blend with diesel results in less pollutants, it does not demand more modifications engine. Also, this reduces country’s import bill. Furthermore, suggests alternate sustainable income among...

Abstract Fossil-based production of plastics represents a serious sustainability challenge. The use renewable and biogenic resources as feedstocks in the plastic industry is imminent. Thermochemical conversion enables molecular building blocks materials from widely available resources. Waste cooking oil (WCO) significant fraction these This work provides insights into thermochemical fatty acids...

Two bacterial strains phylogenetically identified as Pseudomonas aeruginosa strains RM1 and SK1 displayed extensive degradation ability on waste engine oil (SAE 40W) in batch cultures. Spectrophotometric analysis revealed the presence of various heavy metals such as lead, chromium and nickel in the waste engine oil. The rate of degradation of waste engine oil by the isolates, for the first 12 d...

due to the high price of virgin vegetable oils and the drawbacks of the homogeneous catalytic transesterification, in this work an economically profitable alternative process was proposed for biodiesel synthesis in which transesterification of the low-cost waste cooking oil (wco) with methanol in a heterogeneous system was done. alumina impregnated with sodium hydroxide was utilized as a solid ...

Reduction of fossil fuels sources, increasing of pollution gases emission, and global warming effects increase the demand of renewable fuels. One of the main candidates of alternative fuels is biodiesel. Biodiesel limits greenhouse gas effects due to the closed CO2 cycle. Biodiesel has more biodegradability, lower combustion emissions such as CO, SOx, HC, PM and lower toxicity than petro diesel...

This work explores the feasibility of using waste cooking oils (WCO) as eco-lubricants. Five WCO from different food facilities were studied. Three them fractionated into both lighter and heavier fractions by molecular distillation. A comprehensive chemical characterization (fatty acids distribution, polar compounds acidity) was carried out on all WCOs their fractions, which led to set relation...

Biodiesel has gained wide acceptance as an alternative to petroleum-derived fuel due its environmentally friendly characteristics such low aromatic and sulfur content, biodegradability exhaust gas emission. Although many types of feedstock could be used produce biodiesel, waste cooking or frying oil (WCO) is a promising multiple-advantage solution. However, the use WCO biodiesel some drawbacks:...

Waste cooking oil (WCO), in many cases, can rejuvenate aged asphalt and restore its properties. However, the influence of WCO qualities on rejuvenation behaviors of aged asphalt has not been investigated in detail. The objective of this paper was to evaluate the effects of WCO viscosity and acid value on the basic, rheological, and chemical properties of a typical rejuvenated asphalt. Penetrati...

Abstract Fatty acid methyl esters (FAMEs) are sustainable biofuel that can alleviate high oil costs and environmental impacts of petroleum-based fuel. A modified 1200 W high-efficiency food blender was employed for continuous transesterification various refined vegetable oils waste cooking (WCO) using sodium hydroxide as a homogeneous catalyst. The following factors have been investigated on th...
