DEVELOPMENT OF AN INTEGRATED METHODOLOGY FOR THE MANAGEMENT, TREATMENT AND VALORISATION OF HAZARDOUS WASTE

Abstract: 

Huge quantities of hazardous wastes are produced annually in Greece. Due to the strict environmental legislation and absence of hazardous waste landfills, the only management option is their transportation and treatment abroad, resulting in dramatical increase of the total waste management cost.

The objective of this project is the development of innovative integrated schemes for the treatment of hazardous wastes and contaminated marine sediments to

  • recover containing metal values,
  • produce high added value glass-ceramic end-products, and finally
  • stabilize the pre-treated or untreated wastes, sediments, or residues produced from metal recovery processes by applying conventional or innovative Stabilization/Solidification (S/S) methods, vitrification techniques, active capping options, or surface coating techniques aiming at their environmentally safe disposal. Therefore, either no wastes or stabilized wastes are produced.

The development of integrated systems requires a multi-scientific approach. 4 research teams and a visiting researcher participate in the project.

Seven WPs were proposed; the WPs corresponding to the main objectives of the project and the results anticipated from its implementation are:

  1. The development of innovative combined metallurgical and benefication schemes for the recovery of metal values from hazardous waste (tanneries sludges and ashes, bauxite residues) (WP3).
  2. The development of high added value commercial glass-ceramic products from wastes and residues of their metals recovery process (Task 5.3).
  3. The S/S of tanneries sludges and ashes (Task 4.1) and vitrification of wastes (Task 5.2).
  4. The S/S of marine (harbour) sediments using industrial wastes, nanomaterials, mixtures of sand and active materials or by applying phytostabilization techniques (Task 4.2).
  5. The development of artificial coatings on sulphidic surfaces to prevent oxidation and acid generation (Task 4.3).
