With their higher sustainability index, biofuels, environmentally-friendly and renewable nature is a viable alternative energy source in the transportation sector. This study presents effect of waste cooking oil (WCO) biodiesel on performance, combustion, emission from compression ignition engine. The was blended with diesel varying proportions 5% 95% (designated as B5), 10% (B10), 15% (B15), 2...

Cooking conditions affect oil properties and consequently, the quality of derived biodiesel. Nevertheless, little information regarding impact cooking process on biodiesel is currently available, especially for palm Therefore, this study examined effect temperature, time use, length reuse, selected produced from palm-based waste oils (WCO). Several WCO collected restaurants belonging to four ca...

One of the most concerned components in world’s food system challenges is waste, and it particularly a critical issue developed countries. Waste cooking oil (WCO) one liquid wastes that are recyclable. A proper recycling practice WCO helps to reduce adverse impact on environment can be reused by converting into industrial products such as biodiesel soap. With rising cost crude global market dep...

The recyclability of waste cooking oil (WCO) as rejuvenator for aged asphalt mixture improved the serviceability pavement itself. Currently, researcher is exploring new potential WCO modifier binder modification. However, issue compatibility properties in modification with arises since poor mechanical performance globally recorded thus reflected weakness adhesion bonding inside material. Basica...

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 ...

BACKGROUND Oleaginous yeasts are fast emerging as a possible feedstock for biodiesel production. Yarrowia lipolytica, a model oleaginous yeast is known to utilize a variety of hydrophobic substrates for lipid accumulation including waste cooking oil (WCO). Approaches to increase lipid content in this yeast include metabolic engineering which requires manipulation of multiple genes in the lipid ...

Biodiesel is biodegradable and non-toxic has a low carbon content, high lubricity, <p>Biodiesel higher ash point than diesel. The purpose of this study was to obtain data on the physicochemical properties biodiesel from waste cooking oil (WCO) produced with different amounts catalyst in transesterification process. Methods This research carried out two-step process: (1) esterification an ...

Microbial synthesis of wax esters (WE) from low-cost renewable and sustainable feedstocks is a promising path to achieve cost-effectiveness in biomanufacturing. WE are industrially high-value molecules, which widely used for applications chemical, pharmaceutical, food industries. Since the natural resources limited, production mostly rely on chemical rather expensive starting materials, therefo...

Biodiesel obtained through the transesterification in methanol of vegetable oils, such as soybean oil (SO) and waste cooking (WCO), cannot be used a biofuel for automotive applications due to presence polyunsaturated fatty esters, which have detrimental effect on oxidation stability (OS). A method upgrading this material is catalytic partial hydrogenation acid methyl ester (FAME) mixture. The t...
