SEPROSYS

What SEPROSYS does

SEPROSYS SAS is a privately held French engineering services firm founded in 2009 by Stanislas Baudouin and Delphine Dufour, headquartered in La Rochelle, France. The company specializes in molecular and basic purification processes, applying separative technologies including tangential filtration, preparative chromatography, ion exchange, chemical and enzymatic catalysis, and membrane filtration (microfiltration, ultrafiltration, nanofiltration, reverse osmosis). It operates a B2B consulting and project-based model serving the chemical, pharmaceutical, and agri-food industries as primary segments, with additional applications in mining and metals (hydrometallurgy), aquaculture (fish farming water treatment), and cosmetics (marine algae-derived actives).

The company monetizes through three main streams: consulting, audits, training and patent development in separative techniques; the design, supply, and rental of custom-built pilot plants (Taylor-made Pilot Units) ranging from liters to cubic meters per day, available as manual or fully automated skid-mounted systems and deployed via on-site pilot tests; and laboratory services including physico-chemical analyses of ion exchange resins and process evaluation. It has built a portfolio of at least 11 granted patents spanning macroalgae fractionation, metal separation at over 99% purity without organic solvents, fruit juice deacidification, cane sugar vinasses valorization, carboxylic acid separation, tobacco extract treatment, and aquaculture water treatment. Two branded cosmetic ingredients, R001-SYS (anti-ageing) and P001-SYS (dermocosmetics), extend the service business into proprietary ingredients.

The firm runs with a small employee base of 8, is founder-owned with no external funding or institutional investors disclosed, and operates primarily at regional/Western European scope. It holds strategic research partnerships with the Marine farm of Douhet (sustainable algae sourcing under the Neuronalg Project) and the University of La Rochelle (biological activity evaluation, co-published patents and thesis research). Its competitive positioning rests on total confidentiality of engineering processes, a green/eco-extraction approach, and the ability to produce semi-industrial representative batches for industrial extrapolation.
