If Columbi Farms will get their means, the way forward for rising greens might be right here roundroundCircularity is about reusing sources as a lot as attainable. scale back greenhouse gasoline emissions, scale back environmental air pollution and produce vitality.
And all of it begins with one hatchery hatchery Farmed fish earlier than it’s massive sufficient to be launched on massive farms.deep within the fjord in Malm in Trøndelag.
Right here, cloudy water containing urine and fish feces is transformed into nutritious manure.
Fish droppings as fertilizer
Tens of millions of children swim in Salmar’s thoughts. They eat meals, breathe, urinate and defecate within the water and this subsequently must be modified commonly.
In a sequence of instances, Dagens Næringsliv has revealed that a number of hatcheries are dumping this water into the fjords.
However the soiled water can turn into a gold mine.
On the Salmar manufacturing facility, the water should undergo a sequence of filtration processes. Firstly, a filter that removes most meals particles and sludge. That is transformed into biogas.
The water then goes in pipes to Columbi Farms. There they’ll extract nitrate, phosphorus and potassium – from fish feces. These are substances that crops must thrive and develop.
The clear water is then returned to the hatchery.
Can strengthen meals safety
The manure will probably be utilized in Columbi Farms’ vertical farm. In a vertical farm, farmers place greens on cabinets that they stack on high of one another in excessive towers.
On the cabinets they get mild from LED lamps, water on to the roots and the farmers do not need to make use of pesticides.
Normal Supervisor of Columbi Farms, Ole Nordal, believes that fertilizing the crops with vitamins from the fish farm has many constructive properties:
It may strengthen Norwegian meals safety by permitting farmers to develop all 12 months spherical, whatever the local weather. Farmers may develop extra greens that aren’t so widespread in Norway.Native manufacturing reduces emissions when importing greens.However not solely the Norwegian market can profit from the strategy.

Salad farmer Anders Hørthe from the Hørte farm in Lier is a associate of Columbi Farms.
– For me, as a easy soul of a farmer from Lier, it’s good to take part on this circularity and take into consideration what we will create from the vitality, the nutrient-rich water, he says.
Nice export potential
The fertilizer from Salmar can doubtlessly produce 350 million meals (150 grams of salad) per 12 months. Columbi Farms will be capable of produce 20 million. They’ll subsequently be capable of promote surplus fertilizer to different components of Norwegian agriculture.
Hørthe hopes that their expertise will scale back the necessity for imported fertilizer.
– It is not a lofty purpose, he says.
The method of constructing fertilizer is dangerous to each the surroundings and the local weather. It requires massive quantities of fossil gasoline, along with the truth that acquiring the mandatory minerals converts massive areas of land into mining actions.
Want cash
However there are a number of obstacles on the way in which to the long run.
The ability that Columbi Farms goals of is a large vertical farm with 80 rising towers, every 15 meters excessive and with 72 rising cabinets on every ground. Building of the primary twenty towers is predicted to start within the fall of 2024 and be commissioned in 2025.
The venture has a price ticket of NOK 335 million, and up to now the financing has not been totally secured.
Nordal will not go into element about how a lot funding they’ve or the place from, however that they’ve assist from present house owners. He has confidence:
– We’re involved with market gamers in Norway and Europe. In parallel, we’re engaged on financing the primary building section, and on the similar time we now have a great dialogue with the coverage equipment.
Furthermore, such an influence station requires massive quantities of energy, in a scenario the place Norway may face an influence scarcity as early as 2027.
