Combustible waste

Combustible waste used for energy recovery. From Stormossen’s area, combustible waste is delivered to Westenergy’s incineration plant where it is converted to district heating and electricity.

What can be sorted as combustible waste?

  • eggshell
  • plastic objects that are not packaging or dirty plastic packaging
  • cardboard, paper and cardboard that are wet and dirty and are not suitable for other forms of recycling
  • disposable containers
  • textiles, shoes, bags, rubber, leather
  • hygiene items, nappies, sanitary products, makeup, razors, brushes
  • office accessories; files, plastic folders, CDs and DVDs
  • ash, cigarette butts
  • cat sand, dog waste bags, animal litter
  • dust bags
  • certain types of light bulbs, ceramic, porcelain and glass items

In properties with 1-4 homes, biowaste can be sorted as combustible waste if the property lacks a separate collection container for biowaste. We recommend that all households sort biowaste separately because material recycling is more sustainable than energy recovery.

What should not be sorted as combustible waste?

  • hazardous waste
  • electrical and electronic scrap
  • metal
  • large objects that do not burn
  • large amounts of objects that do not burn
  • waste that can be recycled

How are non-combustible items sorted?

Small quantities of light bulbs, porcelain, ceramics, ovenware, mirror glass and cat litter may be sorted as combustible. They do not burn but they cannot be recycled in any other way either. Westenergy’s incineration plant can handle small amounts from households; larger quantities are received at the waste reception station.

Non-combustible objects remain in the bottom slag at Westenergy. It is then delivered to Suomen Erityisjäte where it is recycled into products such as paving etc.
