The Circular Material Unlocking the Full Potential of Sargassum

OCEANRESIDUE™ is the nutrient-rich biomass left after Origin by Ocean’s patented biorefinery process. Instead of becoming waste, this fraction is transformed into a versatile, carbon-capturing raw material, supporting applications across agriculture, materials, and nutrition.
Unlike most biomass side-streams, OCEANRESIDUE™ is designed to add value – not cost – into circular product development.
  • Low-cost and abundant: High-volume output unlocks industrial-scale upcycling pilot projects
  • Climate-positive: Can act as a carbon sink when used in concrete fillers, biochar, or soil applications
  • Regenerative by origin: Harvesting invasive Sargassum removes excess nutrients, supports coastal economies, and restores marine balance.
  • Technically versatile: Its composition supports multiple industries, from animal feed to composites and horticulture

Soil Enrichment & Biochar

OCEANRESIDUE™ provides organic carbon, minerals, and moisture retention. When converted into biochar, it enhances fertility and sequesters carbon for long-term climate benefit

Seaweed-based feed also decouples livestock nutrition from land-intensive crops such as soy and corn.

Matertials & Composites

OCEANRESIDUE™ offers a renewable, cellulose-rich filler for:

• bio-based plastics
• construction materials (cement reduction, concrete fillers) • bio-composites

Its use can reduce fossil-derived materials and lower the carbon footprint of various end-products.

Growing Media (Peat Replacement)

The residue provides excellent moisture retention and nutrient availability, offering a sustainable alternative to peat for horticulture and seedlings

Animal Feed Supplements

Rich in essential amino acids and beneficial lipids, the residue has been shown in initial trials to be well tolerated by dairy cows, with no negative effects on intake or milk quality.

Calling for circular innovation

Abundant, low-cost, and available at industrial scale, OCEANRESIDUE™ enables companies to test, validate, and scale circular products without the typical cost and availability barriers of sustainable materials.

As Origin by Ocean moves toward commercial operations in Kokkola in 2028, we are actively seeking innovative partners, technologies, and applications to utilize OCEANRESIDUE™ as locally and efficiently as possible.

We invite startups, scale-ups, industrial players, and research-driven companies to collaborate with us in developing new circular value streams across materials, chemicals, energy, agriculture, and beyond.

This is an opportunity to work with a real industrial side stream, at scale, and shape how circular bio-based systems are built from the ground up.
