Construction has begun on what will become the largest land-based aquaculture facility in Iceland, Vísir reports. The company, Landseldi ehf. (also known in English as Deep Atlantic Salmon Project) bases its operations in Þorlákshöfn, South Iceland and eventually plans to raise 40,000 tons of salmon annually. It is also committed to utilizing all of the farm’s biproducts, or sludge, as a rich, “biologically perfect” fertilizer.
Founded in 2017 by entrepreneurs with experience in aquaculture, the construction industry, geothermal energy, and finance, Landeldi, ehf. says its mission is no less than to “inspire the global transition to fully sustainable food production, use terraforming aquaculture to rear an abundance of salmon on land, fertilize the earth, and regenerate the climate.” While fish farming in sea pens has been criticised for its environmental impact, fish farming in tanks on land eliminates many problems such as the possibility of farmed salmon mixing with wild fish and pollution from waste gathering on the ocean floor. Such operations require more energy, but Landeldi claims that Iceland’s geothermal energy can keep the production carbon-neutral and that 100% of the water used in its facility is renewable and sourced from boreholes in its ownership.
Will bring 170 new jobs to booming Þorlákshöfn
Landeldi’s current expansion is part of a three-phase plan. As the company’s website explains, their “production quantity will double every two years. Starting at 5,000 tons in 2022 it will have grown to at least 20,000 tons by 2027.”
The current phase will will create 170 new jobs in the town, which has itself seen enormous expansion in recent years, not least due to a local boom in land-based fish farming. When Landeldi began its first construction phase in 2021, three other companies were developing land-based aquaculture facilities there as well.
“The main construction will be of some 150 to 160 tanks, which will be carried out for a cost of around ISK 70 billion [$4.85 million; €4.59 million] over the next 10 years,” says Rúnar Þór Þórarinsson, Landeldi’s head of sustainability and development. “It’s a really big project and we’re well underway. We’ve had a hatchery at Öxnalækur [a land-based aquaculture farm not far from Þorlákshöfn], where we completely renovated the facilities, and which we bought as soon as the environmental assessment was done. We’ve got salmon in seawater tanks in Þorlákshöfn—big tanks, 15-20 m [49-65 ft]—and we’re building 25 and 30-meter [82 and 98-ft] tanks this year.”
‘The environmental friendliness of land-based aquaculture is close to our hearts’
Þorlákshöfn is particularly well-situated for land-based aquaculture, says Rúnar Þór. “The conditions are unique there because we’ve got the sea, which Iceland itself filters for us. The strata are quite permeable, alternating between sand and [porous] rock, [which started out as lava] in volcanic eruptions 7,000 – 20,000 years ago. And the sea cleans out parasites, plastic particles, and other things that can harm the fish.” (See a more detailed description of this process on the Landeldi website, in English, here.)
Landeldi is also particularly proud of the unique system it has developed to utilize all of its facilities’ biowaste.
“The environmental friendliness of land-based aquaculture is close to our hearts,” says Rúnar Þór. “This is in our DNA as a company. We intend to collect the fish manure and work with other fish farms to utilize it for the good of the land and support agriculture with fertilizer, biochar, and compost production by any means necessary.”
