Of course we can recycle, discard or even burn them: cable reels, window frames, washing machines, diapers, crates, carpet tiles, double glazing panels or old buses. The other option is to put them to good use: Superuse. More and more architects apply these materials in their designs. It requires special attention and new skills, but the resulting images can have quite unexpected qualities. A practical and inspiring book about the construction of new buildings with surplus materials, initiated by the Rotterdam Recyclicity foundation. Richly illustrated with a large number of clear cut examples in the Netherlands and elsewhere. It provides ideas for tools and methods for architects and ’superuse scouts’. Moreover the theme is considered from the ecological and methodological point of view.
