360° sludge management – on land and at sea

An example of Bioretur’s integrated solution for semi-closed sea-based farming systems, where sludge is collected in the sea, dewatered on a barge, and transported to shore for drying and further utilisation.

Bioretur is now expanding its services to cover the entire value chain for safe, documented and cost-efficient sludge management.

Whether the sludge originates from land-based RAS facilities, semi-closed sea systems, ensilage processes or fish processing plants, Bioretur can now take responsibility for the full process – from dewatering to a finished, usable resource.

Aquaculture is evolving rapidly, and the demands for documentation, resource utilisation and emission reduction are increasing. With our 360° model, producers get one coordinated and scalable solution that covers their needs across production methods.

What Bioretur’s 360° sludge management includes:

  • Dewatering and thickening through mechanical solutions adapted for both land and sea
  • Drying with our validated SHS technology, producing a hygienised and stable product
  • Transport and logistics through Bioretur Logistics, optimised for both wet and dry material
  • Reception and further processing at regional DryHub locations
  • Sustainable resource utilisation, enabling the sludge to be used in fertiliser or other value chains

Bioretur does not provide the actual collection in cages or pipelines, but takes full responsibility from the moment the sludge is extracted from the production system — through dewatering, drying, transport, treatment and final product.

Integrated, safe and cost-efficient sludge management

By combining technology, logistics and regional infrastructure, Bioretur can now deliver a complete service model that makes it easier for producers to:

  • Maintain control of costs and logistics
  • Reduce emissions and transport needs
  • Meet upcoming requirements for hygienisation and documentation
  • Ensure sustainable and traceable resource utilisation

Where today’s sludge solutions often consist of standalone components, Bioretur now offers a fully integrated system that ensures predictable operations and low total costs.

In short: One supplier. One agreement. Full visibility, and a safe path from sludge to resource.
