Industrial symbiosis for recirculating aquaculture

Purpose and goal

The purpose of this pre-study was to enable realisation of industrial symbiosis, giving a high quality and quantity yield of fish or shellfish while recycling nutrients, materials and energy. One of the goals fulfilled are product design of basins in three different scales of models. In accordance with the goals of the project we outlined a specific case study with an industry having an existing source of residual heat and organic waste. This will result in a new biofloc production of the fish Tilapia based on waste heat and nutrients.

Expected results and effects

Apart from the resulting new biofloc production to-be, based on industrial symbiosis, the project has also started dialogues with different actors. We will for example continue developing ideas together with the head waste manager in Gothenburg, other interested industries having waste heat or nutrients, entrepreneurs etc. Another important result of the project is how small scale fish production or aquaponic production offers a possibility to help increase the social sustainability in a city/town.

Planned approach and implementation

The project was run in a collaboration between the four partners and supervised by the reference group. Four meetings were held with the reference group, and the project partners was in contact thorughout the project. In the beginning the pace was slower than expected due to e.g. sickleave. The project partners worked in parallel developing basin designs, calculating costs, evaluating production systems and feed sources, running dialogues on potential new production sites etc.
