An aquaponic-system for emission free tomato and fish production in green houses

The aim of the project is to produce vegetables and fish in greenhouses under emission free conditions. In this way water from the aquaculture section containing nutrients is mechanically and biologically purified and given to the plants if necessary. Water and soluble nutrients are taken by the plants.

Evaporated water is extracted from the greenhouse atmosphere via cooling traps and re-fed back into the aquaculture system. Thus water will be re-used and only less than 3% of the make-up water has to be added per day. The energy needed is produced by a photovoltaic plant.
