Hazardous waste

Problem waste may also be called hazardous waste. Problem waste must always be separated from other waste.

Medication can be returned to the pharmacy, explosives to the police and electrical devices and batteries to their respective collection points. For example batteries are collected at many supermarkets.

Hazardous waste will be processed in order to render it harmless, and any emissions are controlled with highly developed processes. Problem waste does not end up piling up at the collection facility – only waste that cannot be reused will be sent to a repository. Other waste will be incinerated and the heat from this process will be converted into electricity and heat for district heating systems. The remains of the incinerated items may be reused for example as earthwork materials.

Examples of problem waste:

  • old medication
  • fluorescent tubes, compact fluorescent lights and energy-saving bulbs
  • electrical devices
  • batteries, button cell batteries
  • mercury thermometers
  • solvents, like turpentine, and solvent-based detergents
  • paints, glues, varnishes, resins and wood treatment and preservation oils
  • aerosol cans
  • alkaline detergents
  • pesticides and disinfectants
  • new year's tins
