Travessa Alexandre da Conceição s/n 3830-196


ALGAplus is a portuguese SME originated in the transference of academic knowledge to a business activity. We produce, process and commercialize sustainable and high quality seaweeds and seaweed-based products. ALGAplus seaweeds are mostly produced in land-based cultivation systems, under the Integrated Multi-Trophic Aquaculture (IMTA) sustainable concept. Infra-structures for production include a indoor nursery, a land-based tank cultivation system with several capacities as well as earthen-ponds with variable sizes (starting at approx. 3000m2) with water renewal related to the tidal cycles. Processing currently includes washing, low-temperature drying and milling. We keep a strong focus in R&D activities to continuously optimize processes and bring new seaweed-based high value products into the market. In a near future we intend to offer also seaweed-derived products, such as seaweed extracts, fully characterized in terms of bioactive properties, to be used in food, nutraceutical and cosmetics products. ALGA+® seaweeds are the solution for the food, cosmetic and feed customers seeking a natural and healthy ingredient assured with quality, traceability, organic certification, stability of supply and a small carbon-foot print that can help to differentiate their products. Our customers benefit from continuous support that includes biomass customisation, development of new seaweed-based products and the domestication of new species of interest. In order to boost the western seaweed market, we also work close to the final consumer. Tok de Mar® (food) and SeaOriginals® (well-being) products are developed in-house and in partnership with universities and ALGA+® customers. After one year in the market, our products can be found all over Portugal and also in France, UK, Poland, Switzerland and Australia. Food companies, speciality retailers (natural, organic, gourmet and seafood) and restaurants are now our main customers.

Ulva, Porphyra and, if possible, a kelp species will be grown using specific cultivation methodologies adapted to each species traits according to the knowledge gained so far on these species production. Comparisons on yields, bioremediation efficacy and chemical composition will be done between our own cultivation site (North of Portugal) and the cultivation facilities at IPMA.
