Microalgae as Sustainable Renewable Energy Feedstock for Biofuel Production

Table 1

Comparison of oil content, oil yield, and biodiesel productivity of microalgae with the first and the second generation biodiesel feedstock source [17, 18, 21, 22].

Feedstock source	Oil content; (% oil by wt. in biomass)	Oil yield (oil in litres/ha/year)	Biodiesel productivity; (kg biodiesel/ha/year)
Oil palm	36	5366	4747
Maize	44	172	152
Physic nut	41–59	741	656
Caster	48	1307	1156
Microalgae with low oil content	30	58,700	51,927
Microalgae with medium oil content	50	97,800	86,515
Microalgae with high oil content	70	136,900	121,104
