Lingalaks purchases Framo LiftUP’s sludge collection technology

August 15, 2022  By RAStech staff

Lingalaks will be the first fish-farming company in Norway to commercially utilize sludge collection technology from Framo LiftUP at its premises.

The sludge collection system is due to be installed in four net pens at Lingalaks’ farming site in Djupevik in the Hardangerfjord. The company trialled the technology on a small scale in 2019, and have now decided to go for more extensive use.

“This waste is a vast unexploited resource, which is why we are investing. We have collected sludge to some extent before, but with the Framo LiftUP technology we have an opportunity to do this on a large scale,” said Kristian Botnen, CEO, Lingalaks. “It currently costs money to dispose of the waste, and we wish to take the lead and create a circular economy. We believe that exploiting these resources is the way forward.”


The technology has been developed in collaboration with environmental organizations, and has recently been trialled as part of a 16-month Innovation Norway funded project at Lerøy Sjøtroll in Osterfjorden; a site that has facilitated pioneering testing of the new sludge collection technology.

Project manager Georg Melcher in Lingalaks points out that the company started using algal oil as a replacement for fish oils in the feed in 2018, and now uses the sustainable product as a standard ingredient in the feed.
