“…The water content of the blended domestic FOG was on average 4.2 ± 2.3% (Table 2), being slightly higher than that reported for UCOs generated from the food industry, ranging from 0.04% to 1.4% with an average of 0.2% (Cheah et al, 2016; Hailei & Hui, 2014; Sanford et al, 2009; Sanli et al, 2011; Supple et al, 2002). This result was posited related to the more complex generation pathways with domestic FOG than UCOs.…”

“…The collected FOG had FFA content similar to UCOs, with FFA levels measured at 2.7 ± 0.3%. UCOs typically contain between 0.1% and 9.0% FFAs and are considered a good biodiesel feedstock (Berrios et al, 2010; Cheah et al, 2016; Sanford et al, 2009; Sanli et al, 2011). By contrast, FFA concentrations are higher in FOG collected from grease separators, ranging from 0.7% to 97.8% with a median value of 34.3% (Canakci, 2007; Karnasuta et al, 2007; Kobayashi et al, 2016).…”

In comparison to fats, oils and grease (FOG) found in commercial and industrial effluents, very little is known about FOG discharged at household level. To address this shortcoming, household FOG production was calculated following a year‐long monthly collection at 2.3 kg/year per household, equivalent to 0.8 kg/year per capita. In the United Kingdom, these numbers translate in an annual estimated FOG production of 62 380 tonnes. Physico‐chemical characterization of household FOG showed promising results for biodiesel production. Biomethane yield was measured at 875 mL CH4/g VSadded, twice as much that of sewage sludge, making it a desirable substrate for anaerobic digestion. It was thus estimated that energy recovery from household FOG through anaerobic co‐digestion or biodiesel production could generate about 490 GWh/year in the United Kingdom. However, insights from participants revealed that most of this waste is currently not recovered, requiring the development of schemes fitting with households' routine to maximize collection rates.

“…Furthermore, a high level of free fatty acid in the feedstock is desirable for the production of synthetic diesel hydrocarbon fuels as it could alleviate the severity of deoxygenation conditions considerably by eliminating the triglyceride hydrolysis step. As reported by Cheah et.al [31], the intrinsic viscous property of neat vegetable oil may impose a higher pumping power and energy consumption requirements due to the frictional resistance to flow freely through the pipeline and catalysts bed under room temperature. As a whole, one can conclude that the desired feedstock for RD production must consists of the following criteria: (i.)…”

“…However, rapeseed, sunflower, and soybean oils are generally unsuitable to be used as feedstock in the Southeast Asia region due to their low crop availability. Thus, many researchers in Southeastern Asia regions, especially Malaysia, Thailand, and Indonesia have incorporated palm oil as the main feedstock for the production of synthetic diesel hydrocarbons due to its abundancy and sustainability [31]. In fact, Malaysia is the world's largest producer and exporter of palm oil today followed by Thailand and Indonesia, contributing over 49.5 % of the world production and 64.5% of global exports [31].…”

The quest of moving from conventional diesel fuels to alternate fuels is never-ending.Renewable diesel stands out as it has a similar molecular structure to that of diesel.Renewable diesel from hydroprocessing of Jatropha oil in presence of ruthenium catalyst is not much researched and the same has been worked upon in this paper. The objective of this paper is to analyze physiochemical properties of renewable diesel (R100), biodiesel (B100), and blends of diesel (D100) and renewable diesel and to check the operational feasibility. Renewable diesel was mixed in 10%, 20%, 30%, 40%, and 50%, by volume in diesel. It was observed that renewable diesel had better cold flow properties than diesel. Calorific value (CV) of renewable diesel and biodiesel was 1.84% and 3.92% less than diesel respectively. Present study shows up to 30% renewable diesel in diesel is a substitute fuel, as their viscosities (2.55, 2.60, 2.64cSt), densities (834.4 kg/m 3 , 831.87 kg/m 3 , 830.6 kg/m 3 ) and CVs (42.42 MJ/kg, 42.30 MJ/kg, 42.09 MJ/kg) are close to diesel (2.42cSt, 837 kg/m 3 and 42.57 MJ/ kg). This is also confirmed by a storage stability test conducted for 24 weeks. Cetane number of blends of R100 greater than 30% are found to be high; this can interfere with engine power output hence requiring amendments in current engines, which is not possible, therefore it is feasible to use blends only up to 30% of R100. GC-MS and Fourier transform infrared radiation showed a higher number of hydrocarbon atoms with diminutive oxygen percentage in R100, vis-a-vis, higher levels of unsaturation with more oxygen in B100.
