During this period, the company focused mainly on providing services in the field of ship maintenance, in particular on repairs and maintenance of ship automation equipment. The collection and disposal services for used oils from marine vessels were also started.

In connection with the lawsuit pending before the International Tribunal in The Hague, initiated in 1990 by a foreign shipowner against the then state-owned port enterprise for alleged monopolistic practices, violation of the MARPOL Convention, and improper operation of the ship when receiving oily ballast water, the Chief Inspector of Marine Environmental Protection of the Maritime Office in Gdynia at that time encouraged the COMAL Company to engage in ecological activities aimed at protecting the waters of the Bay of Gdańsk and port channels. This encouragement included offering administrative and legal assistance during the country's deep economic crisis.

After years of investments and collaboration with research centers such as the University of Gdańsk and the AGH University of Science and Technology in Krakow, as well as environmental protection specialists, the first (and currently the only) installation in Poland was constructed on the shipyard premises. This installation comprised a mechanical-chemical-biological treatment plant for oily water with a saltwater biocenosis, exceeding the standards set by the Helsinki Convention in terms of filtration and disinfection of sewage from seagoing vessels. The installation incorporates proprietary technological solutions that fulfill all sewage requirements in terms of quality, environmental impact, and sanitation, thereby safeguarding the marine ecosystem.

The industrial sewage treatment plant, referred to by the abbreviated name Oily Water Treatment Plant (OWZ), received a water law permit in May 1995, allowing it to discharge treated sewage into the port canal.

In the mid-nineties, a significant demand in repair and production shipyards for services in the field of anti-corrosion works determined the decision to purchase the expansion of specialized equipment and equipment for carrying out maintenance and painting works, as well as modern methods of cleaning steel and concrete surfaces. These services were successfully performed on the orders of the Gdańsk Shipyard "Remontowa", the Naval Shipyard in Gdynia, the Repair Shipyard "Nauta", Gdynia Shipyard and other industrial plants on the coast.

In the 3rd National Competition "Friendship for the Environment", organized in 2001 under the patronage of the President of the Republic of Poland, the company was awarded in the final of the competition in the "Technology Worth Recommending" category. For the progress in the company's development and technological achievements, the company also received individual congratulatory letters from the Minister of Environmental Protection and the Pomeranian Voivode.

The Integrated Permit has been granted to operate a hazardous waste recovery and disposal facility. The quality results of technological processes achieved by the company have been recognized and highly appreciated by the Environmental Protection Departments of the Voivodship and City Office in Gdańsk.
