lower sulfur content, lower aromatic content, and biodegradability. However, govern-
ment policies on biodiesel production can majorly influence the choice of feedstock.
The most commonly commercialized extraction technique, solvent extraction, is
faced with the problem of the environmental unfriendliness of solvents and the release
of VOCs during extraction. The supercritical fluid extraction method proffers solu-
tions to these problems and should be encouraged on a commercial scale. Problems
associated with the supercritical fluid extraction method can be solved if further stud-
ies are carried out. Challenges associated with the production of biodiesel depend
majorly on the feedstock choice and the adopted technique of production. Recent tech-
niques such as reactive distillation and membrane reactor system that solve the prob-
lems of complicated reactant mixture and separation challenges needs to be
encouraged on commercial scale.
