Responsible Management of Waste

Responsible Management of Waste

In line with our environmental policy, we remain committed to the correct collection and utilisation of our waste, adopting waste collection and disposal practices on a large-scale. The production processes of our subsidiaries generate liquid and solid waste, which are separated at the source and collected by suitably licensed professionals for overall management.

The waste produced by the mining activities for obtaining raw materials and by the aluminium production process represent the largest part of the waste generated by the Company. Our efforts for the correct and effective management of this waste focus on the following:

  • Use of a network of collection means (with suitable signage and numbering) covering all installations within the plant of ALUMINIUM OF GREECE.
  • Training and updating of personnel about the methods of use and the collection points by category of waste.
  • Optimisation of the operation of industrial installations to reduce the leakage of materials regarded as waste (bauxite grinding mills etc.).
  • Removal of waste quantities for utilisation or recycling (through third parties). For the quantities for which utilisation is not possible, ALUMINIUM operates premises for the permanent disposal of waste (hazardous, inert and non-hazardous) in the Ag. Athanasios area. These premises serve as the plant’s landfills for separated Disposal of Hazardous and Non-Hazardous Waste, and are operated in accordance with the licensing acts of the Sterea Regional Administration and the Viotia Prefectural Administration, respectively.
  • With respect to managing bauxite residues, relevant efforts focus on exploring the possibilities to use this material in a variety of applications, such as cement production, road works and roof-tile and brick production, and as a component for soil enrichment and improvement (on the basis of relevant completed research carried out by Greek Universities). Additional efforts include activities to attract interest from potential users, as the current trend is to declassify this material from the “waste” category and designate it as a “by-product” of the process for producing bauxite from alumina.

In EPC Projects sector, where METKA is active in the construction of turn-key energy projects, the correct management and disposal of the waste generated is promoted through actions that include the following:

  • Development of a Site Waste Management Plan (SWMP) for every project carried out by the Company. The SWMP, which is developed prior to the commencement of all construction activities, aims to minimise the generation of waste by the project and to examine ways to reuse or recycle this waste.
  • Definition of waste types, categories (urban wastewater, non-hazardous waste and hazardous waste) and quantities, so that waste can be classified for reuse, recycling or disposal using other means.
