The ocean is a major source of renewable resources that remains largely untapped at lower trophic levels. The overall vision of Ocean Bergen is to develop technology and solutions for sustainable production of food, material and energy from the sea.

Filter-feeders are efficient organisms in aquatic environments that are able to feed on low trophic levels. Ocean Bergen is particularly interested in the benthic tunicate Ciona intestinalis, and has explored the use of these organisms as a new resource for both animal feed and biopolymers. In a sister company called  Ocean TuniCell, the tunicate cellulose is refined to a medical grade nanocellulose, TUNICELL, which has excellent properties for use in the biomedical field. The company has built a high technology cGMP facility to produce and deliver TUNICELL to the market.
