“…Biodiesel blends significantly reduced emissions such as carbon monoxide, carbon dioxide with a slight increase in oxides of nitrogen NOx [26,27]. A previous study by Nirmala et al [28] tested pure WCO based biodiesel (WCOBD) and compared the results with that of pure diesel. WCOBD showed 4.2% higher BSFC, 3.6% lower BTE, and 10.8% lower BP than conventional diesel.…”

In this study, waste cooking oil (WCO) was used as a feedstock for biodiesel production, where the pretreatment of WCO was performed using mineral acids to reduce the acid value. The response surface methodology (RSM) was used to create an interaction for different operating parameters that affect biodiesel yield. The optimised biodiesel yield was 93% at a reaction temperature of 57.50 °C, catalyst concentration 0.25 w/w, methanol to oil ratio 8.50:1, reaction stirring speed 600 rpm, and a reaction time of 3 h. Physicochemical properties, including lower heating value, density, viscosity, cloud point, and flash point of biodiesel blends, were determined using American Society for Testing and Materials (ASTM) standards. Biodiesel blends B10, B20, B30, B40, and B50 were tested on a compression ignition engine. Engine performance parameters, including brake torque (BT), brake power (BP), brake thermal efficiency (BTE), and brake specific fuel consumption (BSFC) were determined using biodiesel blends and compared to that of high-speed diesel. The average BT reduction for biodiesel blends compared to HSD at 3000 rpm were found to be 1.45%, 2%, 2.2%, 3.09%, and 3.5% for B10, B20, B30, B40, and B50, respectively. The average increase in BSFC for biodiesel blends compared to HSD at 3500 rpm were found to be 1.61%, 5.73%, 8.8%, 12.76%, and 18% for B10, B20, B30, B40, and B50, respectively.

⎯ this is alternative research fuels in the form of biodiesel from waste cooking oil. In addition, the purpose of this study is to determine the effect of waste cooking oil biodiesel blends in the performance testing of a onecylinder diesel engine simulation modeling. The method used by the author in this study is to use a simulation method. Performance-based diesel motor performance tests are performed using HSD, and also with variations of used cooking oil biodiesel fuel mixtures. From the performance test results at full load, it was found that the comparison of the value of the power mix of biodiesel waste cooking oil with HSD decreased power. At B50 decreased power (6.38%), B60 (7.6%), B70 (8.9%), B80 (10.2%), B90 (11.4%), and B100 (12.7%) at maximum RPM. The torque value obtained in the biodiesel fuel mixture also decreased compared to HSD in the same cycle. The lowest SFOC value is produced by HSD fuel. SFOC HSD value is lower than cooking oil biodiesel mixture which is higher (6.8%) B50 fuel, up (8.3%) B60, up (9.83%) B70, up (11.4%) B80, up (12.9%) B90, and up (14.5%) B100 at full load and maximum RPM conditions.

“…Due to density difference, the washed biodiesel remains at the top allowing the wash water to settle at the bottom. The collected wash water was tested for its pH and the washing cycle was repeated till the pH of wash water collected became neutral (Nirmala et al 2020). Depending on the quality of the waste cooking oil used as the raw material, the number of washing cycles vary from 3 to 5.…”

Food waste has been a complex component added to the Municipal solid waste, making it a major reason for the evolution of greenhouse gases, foul odour and a dwelling habitat for insects and microbes. Diversion of the mixed food waste (unsegregated) to useful materials (activated carbon) would have immense industrial significance. In this study, rice, vegetables, oil and spice (WCVR); mixed fruit peels including banana peel, pomegranate peel, orange peel and lemon peel (MFPW); plain rice (WCR) and mixed food waste (rice, dhal, vegetables, fruits, meat and bones) (MFW) were used. Food waste samples were heated at a temperature of 350 °C for 3 h in an incinerator and then activated with zinc chloride for 2 h in a muffle furnace maintained at 500–600 °C temperature. Zinc chloride activated carbon was characterized through XRD, FESEM and FTIR. WCR carbon resulted to be best-activated carbon, yielding nanomaterials with 2θ = 25.81, 31.76, 34.41 and 56.54, which was in accordance with JCPDS card number. The mixed food waste activated carbon reduced the biodiesel wash water pH from 10 to 6.5 making it suitable for recycle. Turbidity by 98.41%, COD by 41.33%, oil and grease by 99.05% for mixed food waste carbon.
