What ACO Marine does

ACO Marine is a specialized maritime wastewater treatment solutions provider, operating as a subsidiary of the German ACO Group, a global water technology conglomerate with a reported US$1 billion valuation. The legal entity ACO Marine s.r.o. is domiciled in the Czech Republic and sells tailored wastewater management systems for six vessel categories: superyachts and megayachts, cruise and passenger vessels, naval vessels, cargo vessels, RoPax and ferries, and offshore drilling platforms, plus refurbishment and retrofit solutions.

The company's product portfolio covers the full wastewater management stack: membrane wastewater treatment systems (MBR), biological sewage treatment systems, the ACO Clarimar flatpack retrofit solution, marine drainage, vacuum generation and collection systems, push-fit pipe systems (ACO PIPE and GM-X galvanized), grease management, lint filtration, storage tanks, lifting and transfer stations, and UV deodorisation units. A consumables line — OXY Aktiv, ACO ToiZYM, and ACO Descalzym — provides recurring treatment agents and cleaning products. Underlying technology centers on membrane bioreactor and biological treatment processes adapted for maritime constraints such as space limitations, vibration, and marine environmental compliance (MARPOL, IMO, REACH, CLP). The company is ISO 9001:2015 certified.

ACO Marine generates revenue through three streams: equipment sales (treatment plants, drainage, vacuum systems, pipe networks), service and maintenance contracts including spare parts and post-warranty support, and recurring consumable sales. Pricing is quote-based and not publicly disclosed. Go-to-market is sales-led through a worldwide network of distribution partners and service points, augmented by dedicated service centres in Italy and Japan, a spare parts warehouse in the Czech Republic, and a planned UK service centre expansion. Marketing channels center on the corporate website, a downloads portal with 30+ documents, and an online service request form. The business is privately held within the ACO Group, with no standalone financials, funding rounds, or M&A activity disclosed.

Products and services

• Marine Drainage Marine-grade drainage systems engineered for shipboard applications, covering deck, wet room, and galley drainage for newbuilds and refits. Designed for compliance with maritime classification standards and shipyard outfitting requirements.
• Vacuum System Vacuum toilet and vacuum generation systems for marine vessels, including a vacuum generation unit that produces vacuum for toilet flushing and grey water collection. Targeted at shipyards and operators needing low-water-consumption sanitary systems.
• Wastewater Treatment Plants IMO-compliant sewage treatment plants for ships and offshore platforms, available in membrane and biological technology variants. Designed for newbuild and retrofit across cruise, naval, cargo, RoPax, superyacht, and offshore vessels.
• Membrane Wastewater Treatment System Membrane-based wastewater treatment system for marine vessels, delivering treated effluent compliant with IMO MARPOL Annex IV discharge standards. Suited to vessels with high organic loads and tight effluent quality requirements.
• Biological Sewage Treatment System Biological (aerobic) sewage treatment system for maritime use, breaking down sewage biologically to meet IMO standards. An alternative to membrane systems for shipyards and operators preferring biological treatment.
• Grease Management Marine grease management systems including biological grease traps and grease separators for shipboard galleys and food service areas. Prevents grease from entering drainage and wastewater systems, supporting compliance and operational reliability.
• Lint Filter Lint filtration systems for marine laundries, capturing lint from laundry discharge before it enters shipboard drainage. Designed for marine onboard laundry operations.
• Tanks Marine tanks (including holding and collection tanks) for shipboard wastewater, sewage, and grey water storage. Sized for vessel classes and compliant with marine classification standards.
• Lifting & Transfer Stations Lifting and transfer stations for moving wastewater between deck levels on vessels where gravity drainage is not possible. Used to pump sewage or grey water to treatment plants or holding tanks.
• UV Deodourisation Unit UV-based deodourisation unit for shipboard wastewater systems, reducing odour from holding and treatment systems using ultraviolet treatment. Applied in marine wastewater and grey water systems.
• Push-fit Pipe System Push-fit marine pipe systems including ACO PIPE (stainless steel) and ACO GM-X (galvanized) variants, with EC-Type certification for shipboard drainage and waste piping. Designed for fast shipyard installation.
• ACO Clarimar Flatpack retrofit wastewater treatment system designed to be shipped as kit and assembled in confined vessel spaces. Enables IMO-compliant sewage treatment upgrades on existing vessels without extensive structural work.
• Marine Consumables Aftermarket consumables for marine wastewater systems, including OXY Aktiv active oxygen dosing product, ACO ToiZYM biological product, and ACO Descalzym descaling/cleaning product. Used by vessel operators to maintain treatment plant performance.

Direct peers

• Evac Group: Evac is a direct peer providing marine wastewater collection, treatment, and vacuum systems for cruise ships, ferries, offshore platforms, and naval vessels — the same product categories ACO Marine serves, making it the closest one-to-one competitor.
• Scanship: Scanship is a direct peer providing wastewater treatment, food waste processing, and waste-handling systems primarily for cruise ships. It overlaps with ACO Marine's cruise and passenger vessel wastewater offering and competes for the same shipyard and retrofit contracts.
• Jets Vacuum AS: Jets Vacuum is a Norwegian direct peer offering marine vacuum toilet and wastewater collection systems for cruise ships, ferries, and offshore platforms, directly overlapping with ACO Marine's vacuum system product line.
• Hamann AG: Hamann AG is a German-based direct peer specialising in marine sewage treatment plants, including biological and membrane systems for yachts, cruise ships, and commercial vessels, overlapping directly with ACO Marine's core Clarimar/Maripur portfolio.

Broad incumbents

• Wärtsilä: Wärtsilä is a broad marine systems incumbent offering integrated environmental solutions including wastewater treatment for cruise, offshore, and merchant vessels. It competes with ACO Marine especially on large shipyard contracts and lifecycle service deals.
• Alfa Laval: Alfa Laval is a broad incumbent in marine separation, heat transfer, and environmental equipment, including wastewater treatment systems for ships. It competes with ACO Marine across cruise, cargo, and offshore segments as part of a much wider portfolio.
• RWO (Veolia Water Technologies): RWO, now part of Veolia, has historically supplied marine water and wastewater treatment systems for offshore and shipping. It represents a broad incumbent alternative with deeper R&D and global service reach than ACO Marine.
• Wabtec / CleanWater (BIO-SEA): Wabtec's BIO-SEA ballast and wastewater treatment product line targets the same marine environmental compliance market as ACO Marine, offering biological sewage treatment for cruise and commercial vessels as part of a broader industrial portfolio.

Emerging players

• De Nora: De Nora is an emerging player in marine wastewater and ballast water treatment using electrochemical and disinfection technologies, representing a potential technology substitution risk and adjacent competitor to ACO Marine's biological and MBR systems.
• Techcross Industries: Techcross is an emerging Korean player in marine wastewater and ballast water treatment, primarily serving shipyards in Asia. It overlaps with ACO Marine in the broader marine environmental equipment space and represents a regional competitor, particularly relevant given ACO Marine's Japanese service centre.
