TETRAS

In the project TETRAS, public authorities trigger fish and shrimp farming on land, which reuses water from industries related to energy production and geothermal resources.
In the spotlight

TETRAS aims to improve the economic and environmental sustainability of RAS by demonstrating how these systems can be placed strategically or combined with industrial processes to increase resource use efficiency while producing affordable and healthy food.

One process's waste or residual is another process's resource. 

The TETRAS project addresses a challenge common to regions across the Baltic Sea Region: how to harmonise economic development with social and environmetal goals. Much of the excess water or energy used in industry is lost to the environment. What if we could capture these resources and use them for food production? Specifically, how can we use water in a smart way that balances the needs of industry with state-of-the-art food production systems? The solution is RAS: Recirculating Aquaculture Systems. On its own, RAS are expensive and energy-intensive. However, as industrial "add-ons", RAS can be highly efficient methods of food production. For example, in combination with geothermal heat exchange, water re-use (e.g. so-called "technical" water) or agri-aqua symbioses like aquaponics. Besides food, RAS creates additional revenue streams, e.g. by-products for use in cosmetics, bioplastics, fertiliser, or biogas. TETRAS will show how RAS can be placed in strategic geographic locations, or combined with industrial processes to increase efficiency, while producing affordable, healthy food. The partnership will co-develop regional pilots and standardised tools for municipalities to assess and monitor RAS applications and match them with suitable industries. These tools will allow public authorities to integrate RAS into regional development strategies, contributing to both sustainable waters and the transition to a circular economy in a win-win scenario.

      For two days, Klaipeda Science and Technology Park welcomed TETRAS project partners.
      Getting to know each other. To break the ice, project partners shared about their first projects in the Blue Economy.
      Getting to know TETRAS pilots: Annette Løttrup-Moore describes Pilot #1 which will be located in Lolland-Falster in Denmark with the aim of treating RAS water to be used as technical water.
      Getting to know the pilots: Nele Rogenbaum from IVIA shares about the concept and goals of the Estonian Industrial Symbiosis Agropark (Pilot #3).
      Getting to know the pilots: Nerijus Nika from Klaipeda University presented Pilot #2 which is focused on investigating the potential symbiosis between geothermal resources and RAS.
      Getting to know the pilots: Hilary Karlson and Mette Jørgensen from Guldborgsund Municipality present Pilot #4. The pilot will be housed within the Guldborgsund Zoo and Botanic Garden facilities and aims to establish a small-scale RAS to improve social awareness of RAS.
      During the kick-off meeting, TETRAS project partners worked on a Business Model Canva for each of the pilots.

      "RAS are more than just a way to produce fish or shrimp, they are a way to produce food in a more sustainable, efficient, and responsible manner. By maximising the use of resources through industrial symbiosis, we can create a more circular economy that benefits the environment and the economy, while providing tasty and healthy food."
