Our colleagues Jan Hanus and Lucie Staňková took part in the Circular Economy project at the Stupava Primary School in Slovakia. Pupils of 5th and 6th grade together with them reminded how to manage waste properly - how to prevent waste, reuse things and sort waste. They also learned that waste can be used for energy recovery and how such a waste-to-energy plant works. The short presentation and discussion was rounded off with an escape game, where they experienced first-hand, at several stations, the journey that waste has to take in a WtE plant.
