Algae as a feedstock have been used for many products and applications, and new ones are constantly being discovered. With the recent surge in interest to use algae as a feedstock for biofuels, there is growing interest in utilizing the algal biomass in an optimal manner – not just to produce fuel but also valorizing the co-products of the process. Such an optimal utilization could make algae based biofuels more economically viable.
Valorization of co-products is an attractive option, given the fact that the world has the experience of using algae for a wide array of products. In addition to oil and biodiesel, the starch component of the biomass makes a suitable feedstock for the production of ethanol. The residue that is left over could then be used for conventional animal, fish or poultry feed, or for other nutraceuticals. There are emerging technologies using which the residue could be used to make products such as bioplastics.
