Biowaste

Biowaste is organic decomposing waste:
  • leftovers
  • old food
  • fruit and vegetable peelings
  • animal innards and other waste
  • solid fats
  • coffee grinds and tea leaves
  • teabags
  • filter paper
  • kitchen towels, napkins, paper tissues
  • bone
  • plant parts, withered flowers, cut flowers
  • eggshell
  • egg packaging etc.

Why should biowaste be sorted?

When biowaste is sorted separately, it can be reused as raw material for compost soil and eco-friendly vehicle fuel. In combustible waste, biowaste does more harm than good because the wet waste draws on the energy value at the combustion plant.

Which bag can I use?

Stormoss’s own paper bags for biowaste can be obtained free of charge from all our waste reception stations, citizens’ info points in Vaasa or Vähäkyrö and at our office in Koivulahti (Kvevlax).

Other bag options:

  • paper bag of folded newspapers
  • biowaste paper bag
  • envelopes without windows
  • empty flour bag or other paper bag
  • brown-coloured biodegradable Bioska Kotikomposti or Bioska + bag

DO NOT use plastic bags or so-called biodegradable bioplastic bags. They get tangled in the plant and make the process more difficult.

Tips for easy biowaste sorting:

  • Let the juices and other liquids (not oil) run into the drain. If possible, allow wet waste to dry for a while before putting it in the biowaste bag.
  • You can place strips of egg carton, kitchen towels or newsprint at the bottom of the biowaste bag to soak up excess moisture.
  • Change the bag at least every other day.

Where is biowaste collected?

Properties with five apartments or more have their own biowaste container in the yard. For properties with fewer homes, sorting biowaste is voluntary. You can compost in your own compost, use a multi-bin container, separate biowaste container or use a biowaste pass to the waste reception station. You can also share biowaste bins with your neighbour.

What happens to biowaste?

Biowaste is processed at Stormossen’s biogas plant to become biogas and compost soil. The biogas is sold at the refuelling station next to the waste management centre, Stormossenintie 3. A second station will be opened in the year 2019 at the ABC Service Station (Runsor). Compost soil can be purchased at Stormossen.
