“…Other advantages of biodiesel as compared to petro-diesel include reduction of most exhaust emissions, biodegradability, higher flash point, inherent lubricity [2]. Moreover, Production of biodiesel from animal fats is less expensive than traditional methods like extraction of biodiesel from trans-esterification of soyabean oil [3], [4], jatropha, vegetable oils, waste cooking oils [5], [6] etc.…”

Abstract-Electroplating waste samples were collected from various nearby industries in Aligarh, Uttar Pradesh (India), a prominent place for these industries and it was found that the concentrations of Cr +6 , Ni +2 , Cu +2 and Zn +2 ions were much more than the permissible norms of discharge which causes serious damage to the environment. To cater this issue, these heavy metal ions were extracted from the sample and then converted to their respective oxide nanoparticles by chemical precipitation and sol-gel methods respectively. And then, these nanoparticles were characterized by FTIR and XRD techniques. Also one of the major wastes produced in India is the butchery waste which causes severe health problems and is aesthetically unpleasant. This paper mainly focuses on the production of biodiesel from butchery waste by a new pathway utilizing heterogeneous nano-catalysts of Nickel(Ni +2 ) (extracted from electroplating waste) for the process of trans-esterification, which produces biodiesel which are mono-alkyl esters of long chain fatty acids (FAME-Fatty Acid Methyl Esters).

A major hurdle in commercialization of biodiesel from vegetable oil, in comparison to petroleum-based diesel fuel, is its cost of manufacturing, primarily the raw material cost. Waste cooking oil is one of the economical sources for biodiesel production. NaOH and KOH catalyzed processes for prepared of biodiesel expressed of fatty acid methyl ester were comparatively studied for refined sunflower (Helianthus annuus L) oil and waste cooking oil. Transesterification was carried out using 100% excess methanol; i.e. molar ratio of methanol to oil is 6:1 and catalyst concentration of 0.5% at 60 o C. Fuel properties and specifications such as viscosity, flash point, cloud point, pour point, density, cetane number, and acidic value are determined and compared to each other and petroleum diesel. This study characterizes the fuel properties of biodiesel produced from refined sunflower oil and waste cooking oil using two different catalysts (NaOH and KOH) to provide a comprehensive understanding of biodiesels.

“…At room temperature (25°C), the viscosity of waste cooking oil (48 cP) was about 6 times that of diesel fuel (8 cP) in this study. In their study, Phan and Phan (2008) pointed out that the viscosity of waste cooking oil was approximately 10 to 15 times that of diesel fuel possibly due to the presence of higher molecular glycerides (Esteban et al, 2012). Valdés and Garcia (2006) proposed that after heat treatment presence of functional groups with stronger long range dipole-dipole attractions may be responsible for thicker waste cooking oils.…”

Illegal harvesting and recycling of waste cooking oil, also referred to as "gutter oil" in many countries, poses a great food safety threat. Thus, in this study the feasibility of using waste cooking oil as an auxiliary fuel in the furnace of laboratory waste incinerator was evaluated in terms of toxic pollutant emissions. Two fuel blends (W20D80 and W40D60) were blended from varying proportions of diesel fuel (D100), and waste cooking oil (W100) and their physio-chemical characteristics were subsequently determined and compared. Thermogravimetry analysis (TGA) and derivative thermogravimetry (DTG) of D100, W100, W20D80 and W40D60 showed that diesel fuel consist of more volatile short aliphatic hydrocarbons, while the waste cooking oil and its blends had more thermal stable unsaturated long chain molecules. After the de novo synthesis window of 200-400°C, 40% of waste cooking oil and 60% of diesel (W40D60) was injected at around 500-700°C, and reduced the toxicity concentrations of PCDD/Fs and PCBs by an average of 86% and 94%, respectively. This study demonstrated that, by using waste cooking oil as a fuel blend, not only can reduce the possibility of "gutter oil" being put in the food to damage the health of human beings, but also can be recycled as a kind of green fuel to reduce the emissions of persistent organic pollutants (POPs).
