Composting on properties
Composting is a natural part of the waste management of detached houses in the Helsinki metropolitan area. You can compost garden, food and toilet waste. Compost maintenance is easier and more fun than you think.
Every year we offer free composting courses that are open to all. The courses are suitable for both beginners and experienced composters.
Spring 2020 courses and advice sessions have been cancelled due to the coronavirus pandemic. The autumn course schedule will be available below on this page as it is updated during the summer and autumn.
Useful information about composting
- For composting kitchen biowaste, you need a compost container that is protected against pests.
- Garden waste can be composted in a clean, well-maintained open compost heap, such as inside a frame.
- For composting toilet waste, you need a composting toilet designed for this purpose that is properly enclosed and well-ventilated, or a toilet device that prevents runoff water from entering the soil.
- The compost must be placed and maintained so that there is no harm to health or the environment.
- Please take neighbours into consideration when choosing the location of your composter. Try to place the compost at least five metres away from the border of the neighbouring lot.
Notify HSY of composting if
- there are five or more apartments participating in the composting
- you are composting toilet waste
- you are applying for the emptying interval of the mixed waste container to be extended (to eight weeks)

Composting at holiday homes
Composting is also worthwhile at a holiday home!
If you compost the biowaste generated at your holiday home, you can extend the emptying interval of the mixed waste container to up to eight weeks if desired. Submit a composting notification to us if you wish to extend the emptying interval to eight weeks. If necessary, you can also order additional collections from us if the utilisation rate of your holiday home varies during the year.
If you compost biowaste at your holiday home and recycle other waste so that only a small amount of mixed waste is generated, you can apply for a longer emptying interval of more than eight weeks, using an exemption application.
Please note that you can enter into a seasonal contract for waste transport for a holiday property that is in summer use. This contract is only valid for the summer season, i.e. weeks 18–40. The seasonal contract does not need to be suspended separately, and there is no need to apply for an exemption from the waste management regulations at the end of the season.More information about the waste management of holiday homes
