Our energy and materials technology students started their spring tour with an excursion to Fortum’s circular economy village in Riihimäki. It is a pioneering example of future waste management. We were guided through how municipal waste is separated to biowaste, plastic, metal and fuel for their waste-to-energy plant. And we got our hands on recycled plastic from their Plastic Refinery.
Student Christofer Enlund said “Interesting place. They recycled quite a lot, making a lot of plastic granules. Also communal heating for the whole town of Riihimäki. Produced 120 MW of electricity but used a lot less themselves. They reused their water too at some levels.”
Student Resham Tamang added “It was good. I learned some basic things about recycling, such as the steps in recycling plastics into granules and selling to different companies. I remember well the large collection of plastic waste and the working operating the mixed waste claw at the incinerator.”
