Sorting
We accept invasive alien species from household customers delivered by passenger car, van or trailer at all our waste treatment areas. The Kapula, Lumikorpi and Metsä-Tuomela waste treatment sites have separate skips for invasive plant species. When delivering invasive alien species to the Puolmatka and Karanoja waste treatment sites, please report to the scale and our personnel will guide with unloading. We can only accept larger skip loads of invasive alien species at the Puolmatka waste treatment site in Järvenpää and the Karanoja waste treatment site in Hämeenlinna.
Invasive alien species are accepted at the sites as invasive alien species waste. Invasive plant species are accepted only when packed. Suitable packing materials include, for example, garbage bags or a tarpaulin in which the invasive plant species can be wrapped. The packages must be manually movable and carefully sealed.
Below are more detailed instructions for the disposal of various invasive alien species.
Invasive alien species
Invasive alien species are plants, animals or other organisms introduced outside their natural range with the help of humans, whether unintentionally or deliberately.
Invasive plant species designated as invasive alien species of national concern include, for example, hogweed, Himalayan balsam, garden lupin and rugosa rose. Small amounts of invasive plant species can be sorted into the property’s mixed waste container when packed.
The Spanish slug has been designated an invasive alien species of national concern. Live slugs must not be disposed of as waste. Small numbers of dead slugs can be sorted into the property’s mixed waste container. The slugs should be packed in a sealable plastic container or two plastic bags, one inside the other. Dead slugs can also be buried in the yard to a depth of about 0.5 metres.
Larger numbers of dead slugs and raking waste containing Spanish slug eggs are accepted at waste treatment sites as invasive alien species waste. The raking waste should be packed in two sealed garbage bags, one inside the other. Other invasive alien slugs and copse snails can also be disposed of in accordance with these instructions.
Prevention measures of invasive alien species
If there are harmful invasive plant species in your yard, the property owner must see to their eradication so that the invasive alien species cannot reproduce and spread into the surroundings.
The eradication of an invasive alien species often requires long-term and persistent prevention measures for up to several years. Spring and early summer are the best times for the prevention of invasive alien species, as they have not yet been able to reproduce and grow large. By detecting, identifying, reporting and preventing harmful invasive alien species, you are maintaining biodiversity.
Mechanical prevention of plants covers a wide range of methods from weeding to starving the plant, breaking off the flowers, digging up the roots, and covering the plant with mulch. Chemical prevention seeks to eradicate harmful plants, plant diseases or pests with the help of chemical pesticides. Environmental warnings and restrictions on the use of the products must be taken into account in chemical prevention, seeking to choose the most environmentally friendly option.
Before starting prevention work, it is a good idea to verify the invasive plant species and find out about any protective equipment. For example, care must be taken when eradicating hogweed because of the harmful sap it contains. To avoid skin injuries, the eradication of the plants should be carried out in cloudy weather. Protective clothing, respirator and eye protection are essential equipment when handling hogweed.
