Surplus energy for biological supply of sustainable cities

Purpose and goal

Systems have been identified that can provide a cost effective biological production and that can provide both an ecocyclic production through a return of residues and high cost efficiency through smart use of surplus heat in customized low temperature system. Set goal has been met by that a single proposal has been described for how systems can be developed for the production of vegetables, fish and fish feed in cities or urban boundary zones either alone or preferably together because the interaction between the different systems provides many synergies.

Results and expected effects

Developing targeted pilot studies and feasibility studies very costeffective development can be done, designing new Swedish food production systems. Following pilot plants are proposed: Akvaponi pilot plant in Härnosand. Combination of fish, fish feed and greenhouse cultivation Test facility at Elleholms tomato cultivation in Karlshamn, development of low temperature systems in greenhouses. Pilot, development and quarantine facility for a combined production of biofloc and tiger prawns Feasibility studies to establish operations in at least seven different locations.

Approach and implementation

Systems have been identified that can provide professional cost effective biological production systems and also professional ecocyclic production through a return of residues. High cost efficiency through is provided throug smart use of surplus heat into customized low temperature systems. Set goal has been met by a single proposal described. Systems are developed for the production of vegetables, fish and fish feed in cities or urban boundary zones either alone or preferably together. The interaction between the different systems provides many synergies and is prefered.
