Issuer: Oceanium Ltd

OCEANIUM develops and makes seaweed-based products to benefit people health and planet health. OCEANIUM’s innovative and highly technical biorefinery process extracts maximum value from the seaweed producing in-demand, plant-based food and nutrition products and sustainable, innovative materials with excellent provenance.

Challenge: Increasing drought conditions, soil erosion and extreme weathers events expose millions to food and job insecurity. Oceanium’s business model establishes an environmentally sound supply chain and generates nutritious food and material products without cleared land, fresh water thus ensuring long term food security, and viable alternatives to plastics.


Solution: We use green chemistry principles to develop a sustainable and scalable bio-refinery manufacturing process utilising the whole seaweed to produce products into large end-markets that compete at current price levels with land-based PLA in the case of packaging, and land-based plants for plant protein, fibre and nutraceuticals. Seaweed is one of the fastest growing plants on earth, absorbing carbon, nitrogen and phosphorous, helping to mitigate ocean eutrohpication.


Business model: We generate profits by converting raw material (seaweed) into high value products for sale to food ingredient distributors and packaging converters.

We are purchasing sustainably farmed kelp from European and North American seaweed farmers and producing biorefinery co-products for sale to blue chip companies as well as innovative multinational food ingredient suppliers and materials companies. We plan to replicate and scale our biorefineries in locations across Europe and North America, in close proximity to sustainable seaweed farms, both as stand-alone facilities and in partnership with existing facilities where appropriate. As we scale up, we will continue to develop new innovative products from new species of regional seaweeds. The biorefinery approach allows us to pivot to meet regional demand for end products.

In the past two years, we have progressed from bench to biorefinery pilot scale up (TRL 6); developed three potential material innovations; achieved TRL 6 on food and nutraceutical products; attracted passionate and creative talent; and established supply chain relationships in UK, EU, and North America.
