What GREENFLOW does

GREENFLOW is a privately held Portuguese engineering, marine, and chemical services group headquartered in Coimbra, Portugal, founded around 2020 and operating through wholly-owned subsidiaries including GREENFLOW Marine (S.A.), GREENFLOW Chemicals (Lda.), GREENSPAIN (S.L., Spain), and formerly Greenflow Engineering (merged into Greenflow Marine effective December 30, 2025). The company provides integrated waste management and treatment solutions to maritime ports, industrial waste generators, and chemical product buyers across Iberia, South Asia, and emerging markets in Central Asia. Its core technology is the M-Concept modular port reception facility system, a containerized turnkey platform combining M-CARBON, M-EBS, M-PRESS, M-DAF, M-STRIP, and M-STU modules using coagulation, flocculation, dissolved air flotation, and emulsion treatment to process MARPOL Annex 1, 4, and 5 waste streams.

The business operates three primary revenue streams: (1) engineering and design of waste treatment plants and port reception facilities sold as project-based engagements to ports, port authorities, and industrial clients; (2) maritime waste management services, including direct PRF operations at the Port of Lisbon and a 2023 contract with Lamor Corporation for Bangladesh's first full port reception facility at Mongla Port; and (3) commercialization of industrial solvents and chemical products (demulsifiers, flocculants, coagulants, anti-foam agents, glycols, ketones, etc.) for automotive, pharmaceutical, paints, coatings, resins, and metalworking sectors. Distribution is conducted via direct enterprise field sales, with strategic channel partnerships (Lamor Corporation, Ecoslops) extending global reach; pricing is project-specific and quote-based with no public rate cards. The group holds NP EN ISO 9001, 14001, and 45001 certifications on Portuguese entities, ranks among the Top 5% Best SMEs in Portugal (SCORING 2024 and 2025), and reported combined 2023 turnover of approximately €12.8M from its Marine and Chemicals entities.
