Learning Outcomes:

1. Knowledge based

  • Understanding of the principles of science and technology, which constitute the basis of Integrated Hazardous Waste Management.
  • Familiarization with the European and Greek legislation, which deals with hazardous waste management.
  • Understanding of the definition and the characteristics, which render a waste hazardous, as well as indicative characterization tests.
  • Quantification of acute and chronic toxicity and risk assessment for carcinogens and non-carcinogens.
  • Understanding of the management facilities and of the method used to determine incompatibility of hazardous waste during storage, collection and transport.
  • Understanding of the basic treatment technologies for hazardous waste, such as stabilization/solidification, incineration, chemical oxidation, neutralization and sanitary landfilling.
  • Case studies, such as the management of waste from healthcare facilities.

General Skills:

Skills/Competences acquired
