Green Ports

What Green Ports does

Green Ports Hamburg GmbH is a privately held waste-management company headquartered in Hamburg, Germany, that provides collection, transportation, treatment, and compliant disposal of MARPOL-classified ship-generated liquid waste and hazardous industrial residues. It operates a specialized treatment plant in the Port of Hamburg focused on physico-chemical treatment and biological purification of petroleum residues, along with vessel tank cleaning, oil spill response, and recovered-fuel production. Its core technology centers on a granted 2014 international patent for an oily-waste treatment array that enables zero-waste production and separates water/hydrocarbon mixtures into three recovered streams: high-calorific-value fuel oil, clean water meeting stringent environmental parameters, and a dry solid alternative fuel.

The company is the Northern European arm of the HEC Group (Hellenic Environmental Center), a Greek environmental services group founded in 1993 whose network spans Piraeus, Hamburg, Gibraltar, and Malta. Through exclusive or primary Port Reception Facility contracts in these four locations (including a 35-year concession in Piraeus) and direct industrial-waste services to power generation, cement, and chemical operators, Green Ports delivers an integrated circular-economy platform that converts oily residues into commercially sellable recovered fuels while ensuring MARPOL Convention compliance.

Green Ports monetizes through service-based fees for waste collection, transport, and treatment; product sales of recovered fuel oil to refineries and industrial buyers; and long-term concession contracts with port authorities. The go-to-market is direct enterprise sales to ports, oil and gas platforms, industrial plants, and shipping companies, supported by ISO 9001:2015, ISO 14001:2015, ISO 45001:2018, EfbV, and WHG certifications and active participation in major maritime industry associations. Two Managing Directors (Ioannis Agiostratitis and Georgios Moustakas) lead a team of 50+ employees operating 24/7 across the European footprint.

• Bilfinger: European industrial services provider with environmental and waste-handling offerings to ports, refineries, and industrial plants. Comparable as a broad incumbent serving the same customer verticals (ports, oil and gas, industrial facilities).
• SUEZ (Veolia Group legacy): Historically one of the largest European environmental services groups, now integrated into Veolia but still relevant as a legacy peer. Comparable on regulated waste treatment, water and industrial residue services in European markets.
• REMONDIS: One of Europe's largest privately held waste and water management companies, with strong German industrial and maritime waste operations. Comparable as a broad incumbent operating across overlapping waste streams including industrial residues, hazardous waste, and recovered materials.

Regional players

• FCC Environment: European waste management operator (FCC Medio Ambiente group) with services spanning municipal, industrial, and hazardous waste. Comparable as a regional incumbent in European waste services, with overlapping hazardous and industrial waste capabilities.

Emerging players

• Alfa Laval: Global supplier of heat transfer, separation, and fluid handling equipment — including marine wastewater, bilge, and ballast treatment systems. Comparable at the technology-equipment layer serving the same maritime environmental compliance market, though as a technology vendor rather than a service operator.
• Wärtsilä Environmental Solutions: Marine technology provider offering environmental and ballast water treatment systems. Comparable in maritime environmental technology and waste-handling equipment, though focused on shipboard systems rather than port-based reception facilities.
