Wild Olive Oil as a Novel and Sustainable Feedstock for Biodiesel Production: Overviewed Various Feedstock, Methodologies and Reaction Mechanisms of Different Catalysts.

The over-consumption of petroleum fuel due to the progressive increase in population, transportation, industrialization, modernization as well as improvement in the lifestyle of the society leads to the fast declining of non-renewable resources. Therefore, it is important to discover low cost, environmentally friendly and sustainable surrogates of petroleum fuels. In this regard, biodiesel production is one of the gorgeous solutions for the research community. Contrary to the benefits, the high cost of the biodiesel is the main disadvantage, greatly reliant on the feedstock. In this sense, wild olive oil was explored for the first time as a suitable and novel feedstock for biodiesel technology development. The fatty acid composition was identified by GC–MS analysis whereas various physiochemical properties were determined by ASTM and EN methods. Furthermore, this review paper conveys a detailed overview of biodiesel production technologies, various generation feedstocks and types of catalyst along with their plausible mechanism.
