As shown in Fig. 6, fossil-derived electricity consumption, animal feed substitution, and biocrude substitution are the most impactful parameters to the LCA. Favorable ecosystem quality and water depletion impacts for the combined fuel-and-feed scenarios result from the beneficial substitution of algae meal for conventional animal feed (it is assumed that 75% of the algae meal replaces soybean meal and 25% of the algae meal replaces corn feed).
