Five student groups have been selected for the final of the innovation competition and they will present their circular economy ideas. 

The competition received applications from a total of 29 teams from 14 different countries, from 22 universities and totalling 71 students represented 43 different nationalities.

After a pre-selection process, five teams were selected to present their new circular economy ideas to an international jury on Friday 27 October.

The winning team’s innovation may be developed into a sustainable circular economy service product at Tapojärvi.


The winner of the competition was TeamReact, whose idea was to combine fly ash, a by-product of the forest industry, with wood to produce activated carbon for air and water purification.
