aquaponics

That’s where this new research steps in: coupled aquaponics are closed loop systems that recycle much of the fish effluent rather than reusing it outside of the aquaponic system. Where typically the fish solid waste is disposed of, Gross managed to treat it by anaerobic digestion and recover energy and nutrients into the system to form a near zero waste unit. This is the path to resolving the ups and downs and headaches of balancing the nutrient load in the system and what the plants need as they grow. […]
