Ämmässuo eco-industrial centre

Due to the coronavirus pandemic, we do not currently organise visits to our locations or accept visit requests.

The Ämmässuo eco-industrial centre is a modern circular economy cluster that includes, among other things, an anaerobic digestion plant and composting facility for biowaste, a biogas power plant, a gas power plant utilising landfill gas, and a Sortti Station accepting small loads of waste. The ash and slag from the waste-to-energy plant can also be treated in the area. In addition to HSY, the Ämmässuo eco-industrial centre houses several companies that utilise waste materials and renewable energy generated in the area in their own operations.

We offer opportunities for a guided tour of the eco-industrial centre on weekdays for
• groups from educational institutions, fifth graders or older;
• resident and association groups; and
• specialist groups.

Considerations for visiting
• The minimum group size is 10 people.
• Finnish, Swedish or English can be chosen as the language of the guided tour.
• The visiting hours are from 8 am to 5 pm on weekdays.
• The visitor arranges the vehicle, such as a bus, which is also used for the guided tour.
• The area of the eco-industrial centre is extensive and, for safety reasons, it is not possible to move around on foot.
