Waste Guide provides comprehensive instructions for sorting waste in the Helsinki metropolitan area. The service, produced by HSY, includes information about waste fractions, collection points, and sorting guidelines. The search tool contains thousands of keywords to help you determine what type of waste an item is and where it should be delivered. If you are only looking for sorting instructions, you can find the Waste Guide at https://www.hsy.fi/jateopas.
The Waste Guide’s open data is published as a REST API in JSON format. It contains the same information as the browser version available on HSY’s website. The API is suitable for purposes such as recycling advice, application development, and gamified solutions. Usage requires registration. Detailed instructions for using the API: PDF instructions. (In Finnish)
Note: The API cannot be accessed directly via the download link. You must create credentials—see the instructions.
