Biowaste
Small actions matter.
Give biowaste a chance to be useful
About 25% of the mixed waste collected from households is biowaste. Biowaste placed in mixed waste is incinerated at the waste-to-energy plant, causing important nutrients and humus to be lost from circulation. The calorific value of moist biowaste is also much lower than that of dry waste. When biowaste is separated from mixed waste in sorting, the biowaste can be recovered. You can influence the amount of biowaste at home through wise choices, by buying and preparing only as much food as is needed.
Biowaste treatment
There are differences in the treatment of biowaste in our operating area. Separately collected biowaste from Hattula, Hausjärvi, Hyvinkää, Hämeenlinna, Janakkala, Loppi, Mäntsälä, Riihimäki and Valkeakoski is processed at Envoer Ltd and Gasum Ltd. The remaining pulp is used to produce biogas and fertiliser.
Separately collected biowaste from Järvenpää, Nurmijärvi, Kerava ja Tuusula is processed at the Kekkilä composting plant. Composting is carried out in a controlled manner in a tunnel indoors, and the exhaust gases generated in the process are handled appropriately. You can also compost biowaste on your own property.

Sort into biowaste
- fruit and vegetable peels
- waste from meat and fish
- coffee grounds, filter papers and tea bags
- leftover food, small bones
- eggshells
- spoiled food
- kitchen towel and other soft paper
Only biowaste from the kitchen may be placed in the biowaste container. Drain liquids from leftovers before placing them in the biowaste container. You can also put soft paper or an egg carton at the bottom of the bag to bind moisture. Kitchen towel can be used to soak up small amounts of cooking oil and then placed in biowaste. Larger amounts of oil should be packed in a closed plastic bottle and sorted into mixed waste. You can avoid bad odours by taking care of the cleanliness of the container.
