Marking a milestone in the commercialisation of the BioSeize technology, this first full-scale market installation represents a significant step forward for the solution. It follows an extensive development and testing program carried out in close collaboration between ELDI Aqua, Rotor Aqua, and Lerøy Sjøtroll. BioSeize is designed specifically for the gentler collection and handling of sludge in marine aquaculture operations.

The system preserves the quality of the collected material throughout the entire process. Compared with traditional solutions, the sludge is handled more gently, which reduces processing requirements, potentially increases the value of the end product, and provides better conditions for further utilisation – for example, as fertiliser or biofuel.

“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. This is an important breakthrough in the transition from development to the commercial phase,” said Thomas Myrvold, chief executive of ELDI Group, in a press release.

The solution has been developed to meet clear industrial requirements for operational reliability, energy efficiency and future digital integration capabilities.

“This delivery marks a clear transition from pilot testing to industrial application. BioSeize has been developed to handle sludge more gently, while also significantly reducing energy consumption and requiring less space onboard the feeding barge. The design of the net and collection system ensures complete separation of sludge and mortalities, while greatly simplifying installation, operation and maintenance,” added Yngve Askeland, chief technology officer of ELDI Group.

This delivery to Lerøy represents an important step in ELDI Aqua’s continued investment in sludge and waste management solutions for the aquaculture industry. The company is also experiencing growing interest in BioSeize from other markets.
