ELDI, a subsidiary of Hampiðjan in the aquaculture sector, and the Norwegian technology company Rotor Systems have jointly established Rotor Aqua, a company aimed at developing, implementing, and marketing new technologies and solutions for processing workflows and digital management in aquaculture.
The establishment of Rotor Aqua follows a two-year development collaboration between ELDI and Rotor Systems on a new technology called BioSeize, designed to handle organic waste in aquaculture. The solution was presented at the AquaNor aquaculture exhibition last summer and has already been implemented, attracting considerable attention within the industry. It represents a significant step forward in managing waste that would otherwise settle beneath aquaculture cages.
The BioSeize system was developed to collect uneaten feed pellets along with waste from farmed fish, pump it to the surface, and transport it for onshore processing. A key feature of this technology is that it preserves the waste in its original form and transports it 
using clean water. Traditional methods typically crush and mix everything into a saline slurry, making onshore sorting extremely difficult. With the BioSeize method, the value of the waste increases, while also supporting stricter requirements for traceability, 
biosecurity, and sustainability in aquaculture.
“The BioSeize system, consisting of Fish/It® and ConeCollect, is a clear example of the results achieved when technological development and operational experience work closely together. ConeCollect gathers the waste, and Fish/It is the pumping system that delivers it intact to the surface. The past two years have shown that this collaboration creates significant value for our customers, and with Rotor Aqua we now have a much stronger foundation for continued development and growth,” say Eskil Hansen, CEO of Rotor Systems, and Thomas Myrvold, CEO of ELDI.
Technology Developed to Meet Aquaculture Requirements
A model of BioSeize. The solution has attracted considerable attention at trade exhibitions within the industry.
The aquaculture sector faces increasing demands for operational efficiency, improved resource utilization, traceability, and sustainability. According to the partners, there is a strong need for solutions that enhance visibility and control over complex processes and can be easily integrated into existing operations.
“Our strength lies in the interplay of process expertise, automation, and digital solutions. With BioSeize, we have developed a solution that ensures gentler handling of organic waste while also being designed to meet industrial requirements and support further digital development,” says Yngve Askeland, CTO of ELDI.
Next Steps
In the initial phase, the company will focus primarily on the continued development and sales of solutions for waste management, process automation, sensor technology, and digital platforms. The goal is to develop equipment and solutions that deliver measurable operational and financial benefits for aquaculture companies, both in the short and long term.
