Objectives:
In European Union it is expected that landfills will remain the major waste disposal method. The increase of the public awareness and the legislative pressure, after accession of both partner countries to EU, led to development of modern landfill design and management concepts.

OBJECTIVES Main objective:

  • Investigation of advanced oxidation techniques for the removal of hazardous pollutants from landfill leachates.

Specific objectives:

  • Study design and experiment initiation;
  • Optimization and elaboration of lab scale method for the oxidative treatment of landfill leachates.
DESCRIPTION In European Union it is expected that landfills will remain the major waste disposal method. The increase of the public awareness and the legislative pressure, after accession of both partner countries to EU, led to development of modern landfill design and management concepts. The APOLLO project will facilitate the exchange of knowledge and experience between the researchers from the two teams and will contribute to the progress of knowledge concerning landfill leachate treatment procedures. In addition, the project will allow the formation of a joint researcher team that will assure a better exploitation of the obtained results. The Romanian team will gain knowledge about oxidative treatment methods of leachate and about toxicity and bioavailability test methods. The Slovenian team will learn about the determination of organic contaminants using instrumental techniques. In addition, the present project will facilitate a faster communication between both partners and a detailed knowledge about the research interest of the two partners for future common project proposals. The experience gained during this project will be the base for further common project proposals. The necessity of collaboration between the two research team result from the experience of the Slovenian partner in advanced oxidative treatment of the landfill leachates, the experience of the Romanian partner in organic analysis and the existence of up to date instrumentation in the laboratories of the Romanian partner.
