In the collaborative eTwinning project “The Art of Recycling” we analyse the waste situation and sustainablity concepts at both of our schools to exchange our thoughts develop new strategies together to make our schools even greener! Finally we want to develop guidelines and recommendations in mixed international teams that we can pass on to other European schools to offer solutions and good-practice examples. We started with a small activity about writing Christmas cards before our students decided they wanted to to a follow-up project about the ecological topic outlined above.
