Ämmässuo waste treatment centre receives waste of more than a million inhabitants of the Metropolitan Area, nearly 60,000 enterprises and the public sector. The centre includes, among others, a landfill area, biowaste composting plant, gas power plant and a Sortti station that receives smaller loads.

Local residents and other operators are welcome to bring to the Sortti stations small loads of recyclable waste, hazardous waste and mixed waste. Sortti Stations are located in Kivikko and Konala in Helsinki and in Ämmässuo in Espoo. The Munkinmäki waste station serves the residents of Kirkkonummi.
