When we say eco-architecture, we immediately think of those pre-fab houses, buildings with solar cell roofs or façade, with windmill and more. Today eco-architecture do not limit to the materials used to complete the building anymore. More and more buildings are now built with eco-friendly purpose. The Metal Recycling plant by Dekleca Gregoric Arhitekti is just one of them. The building was erected in Pivka, Slovenia and was built with visions to be fully recyclable when its useful life ends. Aside from its purpose of recycling metal, the building consists of two structures, wherein one is made of metal while the other one is made of concrete.
