Sometimes ago, I saw a friend in São Paulo University in Brazil (Prof Maria Cecilia Loschiavo dos Santos) who work with scavengers and many students, and show many beautiful clothes and materials from wastes, (such as this beautiful cloths in the picture down here). Another aspects I saw was in Indonesia in a project named Clean & Green, in which dirty parts of the cities were converted to beautiful parts and made such as bags or hats.
Now, we see another initiation in Paraguay, where people made different insturments from wastes and played Mozart. Very intresting!!
