Waste cooking oil (WCO) resulted from the frying process with same repeatedly. The use of used can pose a danger to human body, and continuous disposal harms environment sustainability life. This problem was found in Wates Village, Sumbergempol District, especially housewives who are also members Rukun Makmur KRPL village. community service aims provide socialization training (education) making...

Synthesis of biodiesel from various plant oils is realized by the transesterification triglycerides with methanol or a reaction usually defined as methanolysis. The usage low-quality oils, such waste cooking oil (WCO), followed undesirable side reactions result increased content free fatty acids (FFA), and water. presence FFA in WCO requires pretreatment stage before subjecting it to In present...

In the present study, experimental analyses were conducted by using biodiesel derived from second-generation feedstock. terms of cost and accessibility, feedstock has gained more attention due to its environmental approach. Waste-cooking-oil-derived methyl ester was produced through a transesterification reaction in presence synthesized magnesium zirconate (Mg2Zr5O12) heterogeneous catalyst. Th...

This study isolated a novel halotolerant Pseudomonas aeruginosa M4, that was able to degrade oil and produce rhamnolipids. Various carbon sources, nitrogen inoculum ratio, pH, temperature were tested optimize the degradation conditions. The highest rate of 85.20% lipase activity 23.86 U/mL obtained under optimal conditions (5% at 35 °C pH 8). components products different times analyzed explore...

The potential for biodiesel to become the main fuel in future seems be getting brighter with enactment of government policies related implementation Euro 4 standard. In addition, has also launched de-carbonization reduce greenhouse effect by referring International Maritime Organization (IMO) plan which sets a target reducing world carbon emissions 40% 2030 and 70% 2050. To answer this challeng...

Biodiesel from waste sources can be considered as the cheapest and most viable fuel alternative to depleting mineral diesel. In this work, biodiesel has been produced different of oil; grilled chicken oil (GCWO) which is animal based source cooking (WCO) vegetable using transesterification method. The impact variables such temperature, time, amount catalyst on conversion yield were investigated...

Recently, the application of lipase enzyme as biocatalyst in conversion waste cooking oil (WCO) to free fatty acids and glycerol has been trending well. Therefore, present study attempts use WCO which is found abundance Malaysia substrate for halal microbial can be exploited food industry. The workability conversion, however suffers severely due potential denaturation extended reaction time. Th...

Increase in organic waste generation, dwindling nature of global oil reserves coupled with environmental challenges caused by waste oil disposal and burning of fossil fuels necessitated the need for alternative energy resources. Waste cooking oil obtained from the frying fish outlet was analyzed for its physicochemical properties using ASTM D-975 methods. Acid and Iodine values of the oil were ...

We entrapped lipase from Pseudomonas cepacia in polyallylamine-mediated biomimetic silica, and then applied entrapped lipase to the synthesis of biodiesel with soybean oil or waste cooking oil as a feedstock. The effects of reaction temperature, substrate molar ratio (methanol/oil) and n-hexane content (w/w of oil) were evaluated using response surface methodology (RSM) combined with Box-Behnke...
