Don’t waste biowaste!

Biowaste is food scraps and kitchen waste that are decomposable and compostable. When you sort biowaste into the property's biowaste bin, its nutrients can be reused, and it can be used to produce renewable energy.

According to HSY, about half a million kilograms of biowaste were collected from our properties in 2022. That is over ten per cent of all waste collected from our properties. 

However, that is just the amount of biowaste that is sorted into the biowaste bin. A lot of biowaste ends up in mixed waste bins, too. HSY has conducted a waste survey, which showed that in the Helsinki Metropolitan Area, nearly 40 per cent of the waste in mixed waste bins is biowaste. 

It is important that we sort biowaste in the right bin, because it is the only way to reuse the nutrients in biowaste and to use it for renewable energy. Biowaste is used to make biogas and nutrient-rich compost soil.

How to sort

Put into the biowaste bin

Organic, decomposing and solid waste:

  • Fruit and vegetable peels and skins
  • Congealed fats (liquid fat must not be poured into biowaste!)
  • Bones and fishbones
  • Egg cartons
  • Plants, withered flowers and flower soil
  • Coffee grounds, tea leaves, tea bags and filter papers
  • Wood-based bedding for pets (wood shavings and pellets, for example).
  • Tissue paper, such as paper towels, napkins and handkerchiefs
  • Small amounts of raking waste
  • Food scraps

Do not put into the biowaste bin

  • Food packaging 
    Sort empty food packaging into the small metal, plastic, cardboard or glass bins.
  • Plastic bags
    Sort plastic bags into the plastic bin.

Please note! Do not pour grease down the drain. Sort liquid fat into the mixed waste bin in a sealed container. You can soak up residues of cooking oil in a paper towel and sort the paper towel into the biowaste bin.
