Technical Environmental Restoration Study of the Uncontrolled Waste Disposal Site at “Vorato” location

This study concerns the restoration of the Uncontrolled Waste Dump Site of the Municipality of Kefalonia, located in the area of “VORATO” within the Municipal Unit of Paliki. The purpose of the Technical Study was to specify the required restoration work for the site in accordance with the circular issued by the Ministry of Environment, Energy, and Climate Change (P.N. 109974/3106/22-10-2004) on “Standard Specifications for the Restoration of Uncontrolled Waste Disposal Sites,” to issue the Restoration Permit, and then develop the Final Study of the Restoration Works. The Uncontrolled Waste Dump Site in question did not have a Restoration Permit, and no previous study has been conducted on this landfill. The precise characteristics of the site were recorded and studied. Based on this Technical Study, the Restoration Permit was requested to be issued.


The works for the preparation of the Environmental Restoration Technical Study began with a visit to the Uncontrolled Waste Disposal Site located in the area of “VORATO” of the Paliki Municipal Unit. During the visit, the characteristics that the site presents were recorded. Following the recording of the data and based on the technical and environmental characteristics presented by the site, the minimum technical specifications for its restoration were derived. Additionally, reference was made and solutions were proposed for the management of the Municipality’s solid waste after the restoration. Finally, proposals were given for the funding bodies of the restoration of the aforementioned Uncontrolled Waste Disposal Site.

The operation of uncontrolled waste disposal sites causes serious problems both in the environment and in public health and their restoration should begin gradually up to the full operation of waste management facilities (landfills, waste treatment plants, etc.) provided for each Regional Unit. The risks caused by the operation of such sites can be summarized as follows:

  • Pollution of surface (seas, rivers) and underground (irrigation and drinking water sources) waters.
  • Air pollution from the decomposition of organic waste and the production of unpleasant odors.
  • Release of toxic chemicals into the air originating from spontaneous combustion or deliberate burning of waste.
  • Aesthetic degradation of the environment.
  • Starting of fires with risks to public health and the natural environment.
  • Dispersion of waste to neighboring areas.

Restoration measures may include the following:

  • Collection of scattered light “micro-waste” and their transportation to landfills. If this is not feasible, their deposition on a controlled landfill site.
  • Arrangement of the landfill site of hazardous waste so that the slope of the final upper surface of the restored landfill site is at least 5%.
  • Surface covering with concentrated soil materials suitable for planting.
  • Anti-corrosion measures.
  • Construction of works for obstructing lateral inflow of rainwater into the landfill site.
  • Construction of works for collecting and transporting rainwater from the surface of the landfill site.
  • Fire protection measures.
  • Demarcation/fencing and guarding.
  • Periodic inspection of the landfill site, without requiring subsequent care works.
