EPE successfully completed the management and cleanup operation of waste improperly disposed of at a Kosovo Energy Corporation (KEK) power plant in Kosovo.  The project, financed by the World Bank through its Clean-up and land reclamation project, followed international good practice and innovative procedures.


The Power Plant includes gasification and fertilizer plants which are no longer operational and  represented an environmental hazard due to potentially hazardous chemicals that were still contained in materials remaining in pipes and in equipment located on the premises. This waste proved a hazard and dangerous to the communities living and working in the area.


An initial feasibility study and conceptual project for the clean-up and disposal of hazardous and non- hazardous products and waste stored in parts of the tanks and containers of the gasification plant located on the premises were carried out. The Environmental Impact Assessment study was subsequently carried out and then study for clean-up works took place.

The extension of the scope of works of the clean-up was defined by the funds made available by the Dutch Government and the World Bank, and focused on the characterization, on-site treatment and final disposal of hazardous and non-hazardous chemicals which are stored in the tanks and facilities of the plant.  EPE won this project through an international tendering procedure.

The project lasted almost three years, EPE managed the containment, packaging and export from the site of the varying types of wastes.

The project included:


  • The removal and treatment of 20.000 tons of hazardous liquid and solid waste, including organic phenolic waste, solvents, diisopropylether and tar sludge from various tanks at the old lignite gasification plant of KEK.
  • Cleaning of around 20 tanks from historical phenolic liquids and sludges of variable viscosities.
  • Packaging of high contaminated waste.
  • Treatment of 15.000 tons of phenolic liquid waste by employing the Fenton reaction, treatment of sulphates, precipitation of metals and treatment of produced filter cake.
  • Issuance of bilateral agreements between Kosovo and Sweden / Belgium for the export and disposal of 5.000 tons of hazaradous liquid and solid waste, in accordance with the provisions of the Basel Convention for countries not part to the Convention.


This project was important because not only did it eliminate hazardous waste that was affecting the population surrounding the area, but it also helped establish and promote safe practices, including proper waste management, in a country where such precautions were not previously taken.  Remediating land and properly disposing of waste is essential to reviving the environment and life, but establishing safe practices including proper waste management and disposal for current and future operations will protect against future harm.


CHIMA S.A. solvent storage facilities took fire and caused the spill up of almost all solvents which were stored in the plant. Several tanks went off and some exploded causing contamination outside the boundaries of the plant, including the shoreline and sea.


EPE responded to the spill from both sea and ground level.  Spill response operations commenced within a couple of hours from the event.


Soil, water and groundwater samples were collected and analyzed for the classification of the waste and the mapping of contamination. Hot spots were identified and remediated with priority. An environmental remediation proposal was prepared and site remediation actions commenced soon after the event.


All tanks and other structures were demolished to ground level and the site was rehabilitated to its former condition. Follow-up monitoring was being conducted for several months after completion of rehabilitation works.


EPE undertook the rehabilitation of the former phosphoric and sulphuric fertilizer plant in Vassiliko, Cyprus. The project was funded by the Ministry of Commerce of Cyprus and lasted more than one year.


The project began with the clean-up of tanks and pipings from hazardous sludges and acids. The anhydrous ammonia spheres were emptied and cut separately. Waste was treated on site with physicochemical methods. A hazardous landfill was created for the disposal of NORM waste. Enclosures were set up in many locations for the removal of asbestos waste.


Once all hazardous waste was removed from the plant, demolition operations commenced.  Several buildings were demolished including the stack, ammonia spheres, tanks and several other steel and concrete structures.


During the Israeli army invasion of Lebanon in 2006, a number of fuel tanks at the power plant located 30 km south of Beirut, were destroyed, which caused a major ecological disaster. A series of international tenders issued by UNDP and HRC were awarded to Environmental Protection Engineering SA (EPE) for the oil spill clean-up of Lebanon sites, collection, transportation and temporary storage of wastes and development of shoreline survey. For the implementation of the projects, EPE mounted large-scale operations in Lebanon providing experts who have a wealth of experience and knowledge in provision of response and environmental services, trained manpower and specialized equipment and other resources.


Main facts:

    • Following the tanks’ destruction, 15,000 tons of Heavy Fuel Oil were released
    • 100-120km of the Lebanese coastline were polluted
    • More than 20 Lebanon sites were cleaned up by EPE and delivered to Lebanese authorities and public
    • EPE assigned more than 200 personnel for the implementation of the projects
    • 645m3 waste generated from the oil spill were repackaged, labelled and transported for temporary storage
    • 230 km of shoreline were inspected by our experts team 3 years after the oil spill including sea based, land based and underwater surveys

While approaching a mooring off the cliffside tourist town of Thira on Santorini Island (Greece) on April 5, 2007, the cruise ship SEA DIAMOND came into contact with an uncharted extension of rocky reef and suffered hull damage. An emergency evacuation of the 1156 passengers and 391 crew members was carried out. As a result of an oil spillage from the wreck, approx. 6km of shoreline was polluted in what is one of the most touristic areas worldwide.


The backbone of the emergency response and also the project-phase clean-up work was provided by Environmental Protection Engineering S.A. (EPE), contracted by the SEA DIAMOND owners in the early hours of the emergency. EPE quickly began mobilizing its resources from its various bases around the country and arrived on site on April 6 with boom, skimmers, and the first two of the four self-propelled (‘AKTAIA’) skimming vessels it would use in the response. Vacuum trucks, more booms, support vessels, and further ‘AKTAIA’ skimming vessels arrived soon afterwards.


Our group organized and implemented recovery of oil from the sea, plus the protection of the marine and shoreline environment. Among the many services we provided were mobilization of several pollution response/clean-up vessels, specialized equipment and personnel. After completion of the oil collection at sea, shoreline cleanup operations continued, performed by our teams of oil spill technicians and experts which included remediation of all affected rocky and sandy beaches. In 2009, our group returned to the site to assist with offloading of oils and other liquids from the wreck. On this occasion our response included, expanding and maintaining the oil boom/containment area encircling the wreck, hull inspection and cutting/tapping by use of ROVs, pumping, temporary storage and final disposal of recovered oils.
