Learning Outcomes

The course refers to toxic and hazardous waste treatment and management. It is defined what is toxic and hazardous waste and its characteristics. The course includes classification, labelling, regulatory principles, physicochemical, thermal and biological treatment processes, recycling, life cycle assessment (LCA) and sanitary landfilling of hazardous waste. Furthermore, basic toxicology terms are analyzed like acute and chronic toxicity. The principles about risk assessment, exposure assessment and hazard measurement are defined.

The student will learn:

  • The toxic and hazardous waste, labeling, transportation, and storage.
  • Integrated management methods for hazardous waste and toxicology.
  • Risk assessment and management for exposure to toxic and hazardous waste.
General Competencies/Skills
  • Autonomous work.
  • Team work
  • Project planning and management
