The bulk edible oil by-products are pumped or dumped into a processing tank. This food oil becomes an ingredient in a consummable product. Nonedible oil can be used in the original container or transferred to a distribution vessel in either a bulk form or in a liquid state that is metered into the production operation. 

The specifications for biodiesel are designed to ensure that consumers will not experience operational problems from the fuel s use. ASTM and European Union have standard specifications designed for BlOO FAME used in biodiesel blending, which include GC (gas chromatographic analysis), elemental analysis, as well as physicochemical properties of the produced biodiesel [3,4]. Quality fuel will provide the consumer with improved air quality and enhanced operability. Poor quality fuel will create operability problems and increased maintenance activity. It is really necessary to look for newer approaches for the production of biodiesel particularly for variable quality feed stock employing nonedible oils or used flying oils. 

Heterogeneous strong basic Mg/La catalyst was tested for the transesterification of edible and nonedible oils for producing biodiesel. With oil to MeOH ratio of 1 2.5 and catalyst of 20% complete conversion was observed within 0.3 h at 65° C and 2.2 h at room temperature [86]. The catalyst was shown to exhibit good activity for transesterification even in the presence of water and FFA at room temperature.

Engineering major oil crops that will be able to produce useful oils generally produced only by wild and nonedible oil plants. 

Commonly known as croton, this flowering plant belongs to the Euphorbiaceae family and grows wild in tropical and template areas. Megalocarpus represents one of the numerous species of croton revealed as a profitable substitute for Jatropha in biodiesel production, as well as a solution for desertification in Africa, due to lower water requirements and high oil productivity (Milich, 2009). Endemic in east Africa, its nuts produce 40—45% (w/w) of a nonedible oil rich in free fatty acids (Aliyu et al., 2010) traditionally used for medicinal purposes. 

Cold press extraction is the traditional way to obtain this nonedible oil. The need for a high-yield, high-quality and fast neem oil extraction process was the motivation of Nde et al. to investigate the use of altanative energies (eg, microwaves), demonstrating a... 

Due to ecological and economic issues from the first generation of biodiesel, nonedible vegetable oils have become a robust in biodiesel technology. Numerous studies have reported on the potential of nonedible oil used in the production of biodiesel from sources such as Jatropha (Mofijur et al., 2012 Diana da Silva Araujo et al., 2014 Berchmans and Hirata, 2008 Li et al., 2014), Pongamia (Dwivedi and Sharma, 2014,2015), rapeseed (Pullen and Saeed, 2015), mahua (Shadangi and Mohanty, 2014 ... 

There is considerable potential for ASEAN to produce and supply various biodiesel products to the rest of the world due to its natural resource base. However, the use of biodiesel still presents a number of problems which need to be resolved, especially the high price of raw materials and the quality of biodiesel fuels. In view of these limitations, seeking ways to combine various biodiesel raw materials (eg, edible and nonedible oils) is one strategy that could be used to solve the problems reducing the economic cost, utilizing the avaUabihty of raw materials and improving the quality...
