According to present disclosure, there is disclosed an algae growth and cultivation system that provides a cost-efficient means of producing algae biomass as feedstock for algae-based products, such as, fertilizer, feed, biofuel manufacture, and desirably impacts, nutrient recovery from waste streams for valued byproducts production, recycle water, and alternative/renewable energy production. The system as discussed herein is an integrated systems approach to wastewater treatment, algal strains selection for byproducts production, and recycle of algal biomass-processing waste or additional algae harvested as feedstock for products such as fertilizer production. Embodiments of a system as discussed herein present an economically viable algae production system and process that allows algae-derived products such as fertilizer, feed, biofuels, etc. to compete with non-organic or petroleum products in the marketplace.
