Abstract
Systems and methods for the treatment of lipid-extracted algae biomass and recycling nutrients are provided. The lipid-extracted algae biomass is hydrolyzed prior to anaerobic digestion, and the products generated by anaerobic digestion are further processed to yield by-products that are of use either for external use or as process inputs to carry out specific steps within an integrated algal growth and anaerobic digestion process designed to minimize economic costs, required costly inputs while improving upon system capabilities.
