Biodiversity / Soils

Preserving biodiversity is integral part of PPC’s environmental strategy. The Corporation takes measures, in compliance with effective legislation, with regard to the management of the natural environment in lignite mining and power generation areas. These measures aim to ensure the conservation of natural habitats, indigenous flora and wild fauna.

Actions to preserve Biodiversity in lignite mining and power generation areas: 

  • Rehabilitation of land in mining areas
  • Management and development of artificial lakes in hydroelectric projects, HPPs
  • Dealing with and minimizing the environmental impact of Power Plants

PPC has been implementing extensive land rehabilitation programs for many decades in mining areas and pursues the optimal rehabilitation of the affected areas and the selection of the most appropriate end use.  

The large tracts of woodland that were created from planting trees over many years on rehabilitated mine land create ecosystems of great beauty that contribute to environmental protection and biodiversity.  

In HPP areas, reservoirs have taken on a new dynamic by attracting into the wider area important populations of avifauna species of great importance at National and European level. Moreover, the beautiful scenery around reservoirs has encouraged the development of mild tourism activities. 

As far as technically feasible, Power Plants apply relevant anti-pollution technologies and best practices in order to minimize the impact on the environment and ecosystems from the Company’s activities.

In cooperation with entities such as the Hellenic Centre for Marine Research, the National Institute for Agricultural Research, the Interbalkan Environment Centre, the Institute of Marine Biology, Biotechnology and Aquaculture, the Fisheries Research Institute as well as university departments, PPC elaborates programs to monitor physicochemical parameters, studies and research on the equilibrium of ecosystems in order to develop actions to conserve biodiversity beyond what is specified by the legislation.

In the Lignite Centers of West Macedonia and Megalopolis, PPC S.A. implements the environmental rehabilitation programs included in the Environmental Impact Assessments for the Mines. 

The aim of environmental rehabilitation is to harmonize the project sites with the natural environment after the closure of the lignite mines. 

Environmental programs of land rehabilitation proceed in successive annual phases. Each phase begins as soon as an area is decommissioned of mining operations. The main rehabilitation phases consist of laying the final surfaces, checking the gradient of slopes of gangue material deposit, checking soil fertility and laying topsoil, planting forest tree species and creating terrains for general use. 

The stages of new soil rehabilitation are adjusted to the land use assigned to the area to be rehabilitated. According to the assessments new soils can be allocated to the following uses: 

  • Woodland terrains intended for creating livestock zones, rehabilitated woodland and timber production
  • Farming land to be leased to local farmers at low price
  • Recreational areas. Once the works have been completed, lakes will be created in the final mine pits
  • Special uses involving specialized projects, such as motocross tracks or infrastructure projects for the region.

To this date, PPC has developed in West Macedonia Lignite Center and Megalopolis through its environmental rehabilitation plans:

  • Large tracts of woodland by planting trees over the span of several decades, an activity which is ongoing
  • Large tracts of farmland leased to local farmers for a token rent
  • Greenhouses, a model experimental fruit-tree grove with apple, pear, peach trees and other seasonal fruit under an integrated management system, exhibition centers, theaters, motocross tracks, recreational parks,  game reserve 
  • Artificial lake which is considered to be an artificial wetland in a rehabilitated area at  West Macedonia Lignite Center
  • Green zones at selected locations around Mine excavations and Municipal Districts adjacent to the Mines.  

In order to rehabilitate soils in mining areas and upgrade the environment on its delivery to the local population, the Company, aside from implementing approved environmental rehabilitation plans, has prepared and continues to prepare research projects in cooperation with Universities, Higher-Educational Institutes and reputable research institutes and makes consistent efforts to restructure cultivations on rehabilitated soils.
