The words reduce, reuse, recycle and refuse will not have any secrets for us anymore! We are going to undertake a joint adventure with the pupils and teachers from the Notre-Dame de la Sagesse and De Handelsschool Aalst. - Students keep a blog with all the actions to reduce waste. - Students make questionnaires for other pupils at school and for the neigbourhood. - Students come up with actions to keep the school and the neighbourhood waste-free. - Students use the Twinspace to debate on topics related to the reduction of waste, alternatives to packaging... - Students organise excursions and visit each other's school.
