In order do this, a synergetic layout of the individual elements has been proposed in such a way that some of them are on others creating an effect of mutual need and natural-artificial unity. The complex will appear as a promontory that dominates the surrounding flatland and consists of two complementary slopes. From the highway it will appear as a natural hill inviting people to climb up and reach the Pavilion, which tangentially crowns it. From inside the Pavilion (an Orientation Centre) the eastern slope will be seen as a set of terraces that gradually descend like a mosaic bits garden, forming an artificial landscape symmetrical and complementary to the natural one, being encountered only from that position. Below it, different treatment ways will reproduce the natural topography and that one created by the architecture, laying it out in a linear organization of successive terraces that echoes the gravitational character of the selection and recycling process. Due to this, it has been decided not to separate the Orientation Centre from the remaining installations, but rather to site it a top the process allowing us to understand it from the first unloading operation to the final storing of the recyclable products obtained in a perfect continuity with the visitors area and the natural setting.
