Necton - Companhia Portuguesa De Culturas Marinhas, S.a.

What Necton - Companhia Portuguesa De Culturas Marinhas, S.a. does

Necton - Companhia Portuguesa De Culturas Marinhas, S.A. is a privately held Portuguese industrial food and marine biotechnology company founded in 1997 as a spin-off from the Catholic University of Portugal's Superior School of Biotechnology. Headquartered in Belamandil, Olhão, within the Ria Formosa natural park on the Algarve coast, Necton operates two autonomous business units: a Traditional Sea Salt unit and a Microalgae unit. The Traditional Sea Salt unit produces hand-harvested sea salt, Fleur de Sel, and flavoured salts under the Marnoto, Belamandil, and (since 2024) Marisol brands, using ancestral Roman-era methods combined with modern quality management systems and a stack of international certifications (BRCGS, ISO 9001, ISO 22000, Organic, Kosher, Halal, EcoVadis). The Microalgae unit produces phytoplankton concentrates under the Phytobloom brand via Flat Panel Bioreactors (since 1997), Tubular PBRs (since 1999), an 80-cubic-metre production unit (since 2016), and freeze-drying capacity (since 2017), supplying aquaculture hatcheries, aquariums, and research centres. Revenue is generated through three streams: branded retail sales (gourmet shops, supermarkets, and e-commerce in retail pack sizes from 75g to 1kg), a B2B Private Label program serving the majority of major Portuguese retail brands and international partners with customizable packaging and bulk SKUs up to 1000kg, and professional/food-service distribution. Necton exports to 21 country-destinations spanning Europe, North America, South America, Asia, and the Middle East, and has expanded via two material acquisitions (Salina dos Caliçős in 2019 and Allmicroalgae in 2023) alongside the 2024 Marisol brand integration.
