A new form of aquaculture, designed for vertical farming, has been patented by an Australian company which uses rocks specifically formed to support a wide variety of microbes to supply nutrients to the food plants grown in the system. Newcastle woman, Lyndal Hugo is the inventor and owner of the company Orlarock. The system has been prototyped in Vietnam in conjunction with the Dutch Business Association of Vietnam. Lyndal Hugo showcased the system at COP26 this week and has received interest from international financiers interested in industrially scaling the solution.
