League of Waste

“League of Waste” is an online knowledge championship in the form of a board game, organised by DIADYMA S.A. (Waste Management of Western Macedonia) for lower secondary schools (Gymnasia) across the region of Western Macedonia, Greece.

Teams of up to five students and one teacher play live from their classrooms. They move across a shared digital game board by answering questions on waste prevention, reuse, repair, sorting and recycling, and everyday eco-friendly habits. The questions also cover the integrated waste management system of Western Macedonia, the only region in Greece that collects a wide range of waste streams separately and operates a network of reuse centres. Correct answers move the team forward, while route choices along the way add strategy. All teams appear together on the same board, which is projected live.

The championship takes place during EWWR 2026. The semi-final, open to all registered teams, runs on 25 November 2026 and the final, for the top 10 teams, on 27 November 2026. The three winning teams will be awarded, and all participating students and teachers will receive commemorative certificates.

The aim is to help students learn through play that the best waste is the waste we never produce, to get to know the waste management system of their own region, and to carry these habits home to their families and communities.
