“…Biodiesel contains more energy than diesel Biodiesel carries 4.5 units of energy against each unit of fossil fuels [3]. Also, plants can be harvested completely by modern technology and the tops could be burned in the high efficiency distilleries or boilers, which can be used for gasification and could increase the total energy return up to 40% [7] Biodiesel decreases the reliance on petroleum [3] Biodiesel provides and alternative which means when oil runs out we will not be solely dependent on it which will positively impact on the transportation market [3] Biodiesel can be produce locally from renewable sources Biodiesel is possible to manufactured using edible, nonedible, waste oils, fats and oil seeds [3,7,11,21] Biodiesel is biodegradable, non-toxic and nonflammable [3,9,13,22] Bio-diesel degrades four times faster than diesel [9]. The higher flash point makes the storage safer [9] Biodiesel can be used in Compression Ignitions engines without need for modification [9,11,13,14].…”

“…Biodiesel will give and efficient performance in existing diesel engines [14] with no substantial modifications to the engine [9] Biodiesel is environmentally friendly by emitting less pollutants [11,22] Biodiesel has the potential to be a carbon neutral fuel [9,21], due to balance between the amount of CO2 emissions and the amount of CO2 absorbed by the plants producing vegetable oil being equal [9]. Also in general it has reduced greenhouse gas (GHGs) emissions [14] by 78% when compared to petroleum diesel [13].…”

Renewable sources include plants and animal fats, which are the main components of biofuels. Biofuels are free from sulfur, aromatics, metals, and crude oil residues. Since biofuels are more lubricating than petroleum diesel fuel, they are nonflammable and extend the life of diesel engines. As a result of this study, the main chemical and physical properties of biofuels were investigated, including their lubricity, viscosity, calorific value, and cetane number, which indicate the quality of renewable fuels, and compared with the other. We examined and compared the combustion characteristics of various types of biofuels as an alternative fuel, as well as their emissions characteristics. Biodiesel and biodiesel blends are compared to mineral diesel, as well as their performance in CI engines in this study’s review. With modified combustion equipment, biodiesel fuels can potentially reduce air pollution in diesel engines and are a very good substitute for fossil fuels. There is a need for more research and technological development in order for biofuels to become economically viable. Biofuel/biodiesel research should therefore be supported with policies that make their prices competitive with other conventional sources of energy. In the current state of affairs, biofuels are more effective when used alongside other sources of energy.

The increasing awareness of the depletion of fossil fuel resources and the environmental benefits of biodiesel fuel has made it more attractive in recent times. Its primary advantages deal with it being one of the most renewable fuels currently available and it is also non-toxic and biodegradable. It can also be used directly in most diesel engines without requiring extensive engine modifications. However, the cost of biodiesel is the major hurdle to its commercialization in comparison to petroleum-based diesel fuel. Biodiesel is proved to be a potential candidate for partial substitute of mineral diesel oil. The environmental issues associated with the use of fossil-based energy sources have informed the search for more sustainable energy alternatives. This work investigated the potential of producing biodiesel from waste cooking oil (WCO). The work gives ample evidence that oil from eateries in WCO could be used in producing high quality biodiesel in an easy, one-step transesterification reaction without the need for acid esterification which increases the overall cost of the production process.
