ELDI Aqua has taken a major step towards the commercialisation of its BioSeize sludge management technology after signing an agreement to deliver a full-scale pilot facility to Lerøy Sjøtroll.
The project marks the first commercial installation of the BioSeize system and represents a significant milestone for ELDI Aqua as it moves from technology development and testing into industrial deployment.

The delivery follows an extensive research, development and testing programme run in close collaboration with Rotor Aqua and Lerøy Sjøtroll.
“Lerøy’s decision to select BioSeize for its sea-based farming facility at the Blom site confirms that the technology addresses a genuine need for a leading player in the industry,” said Thomas Myrvold, chief executive of ELDI Group.
“This is an important breakthrough in the transition from development to the commercial phase.”
Unlike conventional systems, BioSeize is engineered to preserve the quality of collected sludge throughout the handling process. By reducing mechanical stress on the material, the technology can lower processing requirements, improve the potential value of recovered resources and create better opportunities for reuse in applications such as fertilizer production or biofuel generation.
The technology has also been developed to meet industry demands for operational reliability, energy efficiency and future digital integration.
“BioSeize has been developed to handle sludge more gently, while also significantly reducing energy consumption and requiring less space onboard the feeding barge,” said Yngve Askeland, chief technology officer of ELDI Group.
“The design of the net and collection system ensures complete separation of sludge and mortalities, while greatly simplifying installation, operation and maintenance.”
ELDI Aqua said the Lerøy project is expected to serve as an important reference installation as interest in the BioSeize technology continues to grow in aquaculture markets worldwide, supporting more sustainable and resource-efficient fish farming operations.
