truly circular – reusing nutrients from aquaculture
2020
Columbi Farms is established to reuse nutrients from land-based fish farms as fertilizer for plant production. We focus on finding circular solutions to create new values and reduce environmental footprint.
2021 - 2025
Together with our research partners, Columbi Farms is carrying out research projects to identify synergies between aquaculture and agriculture.
Circular food production
The food gap will require us to produce 56% more crop calories than we produced in 2010. Columbi Farms will produce more food with fewer resources.
2050
We need to significantly increase the food production volume in the years to come. Columbi Farms will contribute to bridging the gap between future demand for sustainable food production and current practices.

PRODUCING SALAD WITH WATER EMITTED FROM SALMON FARMING
Columbi Salmon, NIBIO, Morefish, and BioMar, have conducted a study which concludes that there is great potential in growing plants in the same system as fish. The innovation supports the UN sustainability goals and Columbi Salmon seeks to realise this… -

COLUMBI SALMON INITIATES RESEARCH PROJECT TO MAKE SALMON FARMING CARBON NEUTRAL
(Åfjord, Norway) Columbi Salmon has partnered with Norwegian Institute of Bioeconomy Research (NIBIO), Morefish and Biomar on a research project aimed at reducing the carbon footprint of salmon farming in Recirculating Aquaculture Systems (RAS).
Our process
Circular food production
We reuse nutrient-rich fresh water, free of particles, from the early stages in fish production farms nearby. This water contains essential nutrients for plants, such as macronutrients N, P, K and Ca, Mg and S, and micronutrients B, Cu, Fe, Cl, Mn, Mo and Zn.
The elements are essential for plants development and growth. In our farms, the plant roots are constantly in contact with the nutrient-rich water. We give them their required conditions to effectively assimilate the nutrients from this water, e.g. suitable pH and oxygen levels.
