After the production process, preliminary evaluation of the
biodiesel quality was performed in order to estimate critical
properties of the fuel.Table 6gathers all the measured values for
each biofuel.
As seen inTable 7, the measured fuel properties for sunflower oil
biodiesel derived from freshwater or wastewater are conforming
with the quality standards limits. On the other hand, biodiesel
produced from castor oil could not meet viscosity target limits
