“…In a conventional aquaponics system, the waste is removed from the fish farms to be used in the hydroponic units as nutrients, in this study the waste is retained in a decanter that feeds the biodigester and after the end of the anaerobic digestion process the residue, now biofertilizer, it is mixed with the water that irrigates the plants. The integrated system provides benefits for both systems, with savings of 90% in water consumption (LIMA et al, 2021) In this context, the generation of biogas is a sustainable alternative, considering the benefits to the environment, economics, among others (BANERJEE, 2021).…”
