About Us

Our Group

Our Group (HEC) is one of the world’s largest providers of management services for environmentally harmful streams. It is a prominent force in the industry with unparalleled experience, internationally recognized for the quality, and reliability of its services.

It began in 1993 with the founding of HEC to manage the liquid residues of ships calling at the port of Piraeus

With continuous investments in both know-how and logistical infrastructure, our company has evolved to not only meet but also exceed the ever-increasing requirements of international environmental legislation. This advancement has led to the creation of a nationwide and, subsequently, a global network of Global Green Ports reception facilities.

Global Green Ports specializes in providing integrated port facility services for the receipt and management of residues, including collection, transportation, storage, and treatment, with a focus on liquid petroleum residues.

Our dynamic partnership includes environmental companies in strategic locations: Greece (HEC S.A.), Germany (Green Ports Hamburg GmbH), Gibraltar (Green Ports Gibraltar), and Malta (Green Ports Malta). These companies, part of our Group, aim to expand environmental protection infrastructure in international ports governed by the MARPOL 73/78 Convention.

Since our establishment, our Group’s headquarters have been located in Piraeus, serving as the central hub for managing our activities. Our operations are supported by state-of-the-art facilities specializing in the treatment of oil residues from marine and industrial sources. These facilities use innovative methods, setting a global standard for process innovation

Our fundamental business activities include:

  • The proper management of residues, including collections, transportation, sorting, and treatment of varied waste types – including oily waste or hazardous substances – both onshore and at sea.
  • The efficient and safe  residue storage, coupled with advanced processes that facilitate waste recovery, recycling and material re-generation.
  • The production of recovered fuel and raw materials tailored for refinery operations and other key sectors such as material and cement industries.

We convert the useless into useful, the harmful into valuable and the pollutant into an energy resource, thus adding another crucial link in the chain of life.
