Patent Granted for Sirputis Seaweed Harvesting Equipment

Innovation in Seaweed Harvesting Equipment

Sirputis, in collaboration with Metal Production and Norwegian seaweed growers, has been granted a patent for its advanced seaweed harvesting equipment. This innovative system represents a major step forward in sustainable seaweed farming and industrial-scale biomass collection.

The technology is designed to address key challenges in modern seaweed cultivation, including operational safety, harvesting efficiency, and biomass quality.

How the Seaweed Harvester Works

At the core of the system is a high-pressure water jet that gently separates seaweed from cultivation ropes. Unlike traditional cutting methods, this approach preserves the root system, allowing seaweed to regrow naturally and ensuring continuous production cycles.

The absence of blades eliminates contamination risks and reduces maintenance requirements, making the system more reliable and cost-efficient for operators.

Key Features of the Harvesting System

• Gentle harvesting using water jet technology

• Preservation of seaweed root structure for regrowth

• Integrated rope cleaning for reuse in reseeding

• Modular design adaptable to different species and farm sizes

• Compatibility with conveyors, cranes, and tank systems

• Improved operator safety and reduced maintenance

This modular approach enables flexible integration into different seaweed farming operations.

Application in Sustainable Seaweed Farming

The patented seaweed harvesting equipment has already been successfully tested in Norway, demonstrating its ability to improve harvesting efficiency while maintaining high biomass quality.

By enabling cleaner and more controlled harvesting, the system supports the development of the global blue bioeconomy and scalable seaweed cultivation systems.
