Hazardous waste is what the name suggests. Batteries, accumulators, energy-saving light bulbs, paints, solvents and New Year’s tin are a threat to health and the environment when they end up in the wrong place. 

Hazardous waste includes substances or objects that have been removed from use and pose a special risk to health or the environment.

Hazardous waste includes, for example:

  • energy-saving light bulbs and other fluorescent lights 
  • batteries
  • medicines, needles and syringes
  • accumulators
  • waste oil, oil filters and other oily waste 
  • solvents, such as turpentine, paint thinner, acetone, petrol, fuel oil and solvent-based cleaning agents
  • wet paint, glue and varnish (including nail polish)
  • pressurised packages, such as aerosol cans (that slosh or hiss) 
  • alkaline washing and cleaning agents 
  • pesticides and disinfectants 
  • fire extinguishers and gas cylinders 
  • New Year’s tin
  • mercury thermometers.
