Test facilities will turn sludge from fish farming into food and energy

The contract was signed at the BlueFish trade fair in Ålesund by Knut Eilert Røsvik, Hofseth International AS (right), and Erlend Haugsbø Hyperthermics AS.

Hofseth Aqua AS signed an agreement with Hyperthermics AS for handling sludge.

Norwegian company Hofseth Aqua is expanding its land-based post-smolt plant in Tafjord and is choosing Hyperthermics as a partner for sludge management solutions. - We consider this a breakthrough for our commercial efforts in land-based aquafarming, says Erlend Haugsbø, CEO of Hyperthermics AS.

The plant will verify Hyperthermics' unique system for converting sludge from closed farming into commercial quality products. Hyperthermics is now working specifically on several significant projects within land-based farming and closed farming in the sea. Hofseth's giant project World Heritage Salmon in Røbbervika is one of these.

Project director of Hofseth International AS, Knut Eilert Røsvik, hopes to see new value chains for the sludge during the verification phase in Tafjord.

- The Hofseth Group has a high focus on utilizing resources in the best possible way, both when it comes to getting the most food out of the fish we produce and doing this in as energy-efficient and intelligent a way as possible. Hyperthermics' solutions are innovative and future oriented. The company will be an essential partner for us in the work of building a circular sustainable aquaculture industry, says Knut Eilert Røsvik.

Erlend Haugsbø, CEO of Hyperthermics, is naturally very happy with this agreement:

-The aquaculture industry makes considerable investments to become greener, he says. - With our biotechnology, we will contribute to solving an environmental problem by making the waste into high-quality products, and the verification in Tafjord will open up great opportunities for us. More and more land-based and closed fish farms are built worldwide, and environmental requirements are tightened in most countries.

The plant will be ready for start-up in the first quarter of 2023.
