On the basis of above mentioned issues, macroalgae which is called as ‘‘the 3rd generation biomass’’ is gaining increasingly more attentions as alternative renewable sources of inputs for biofuel production since it can deal with these drawbacks of terrestrial biomass and produce sustainable bioenergy and materials. Macro-algae (seaweed) have several advantageous characteristics such as high yield, low energy cost of production, low cost, low contami- nant levels and low nutrient requirements, which can be confirmed
from the results shown in Table 1 ( Park, 2012 ). Macroalgae do not need land and freshwater for cultivation which is advantageous to the countries lack of land. In addition, macroalgae have a lower cost of the production of food and energy than other energy crops
like corn and wheat. Because seaweed markets are mainly existed in a few East Asian countries where seaweed is utilized as food, hydrocolloids, fertilizer and animal feed (Jung et al., 2013). Macro-algae can convert solar energy into chemical energy with higher
photosynthetic efficiency (6–8%) than terrestrial biomass (1.8–2.2%) (Jung et al., 2013). Moreover, the process of macroalgae pro-duction introduces no contaminants, such as soil which can subse-quently lead to operation problems (McKendry, 2002). Comparing to the terrestrial plants, no utilization of chemical fertilizers and pesticides also reduce the contaminants produced during the bio-mass cultivation. Therefore, macroalgae have high potential as the feedstock of energy production, and may be the best choice as a feedstock for biodiesel production.
content plants, it is meaningless to use the edible oils for biodie-sel production.
