This newly-built sanitary building has a metal structure, aluminium windows and its façade is made of prefabricated concrete panels. The indoor partition walls are brick-made. In Spain the technical sheet of materials do not show information about the traceability of the product. Only wooden products certificated FSC or PEFC has chain of custody. So let’s make a guess about the origin of some raw materials in this building: - Steel structure. There are several steel factories near Seville (such as Acerinox, in Cadiz) but iron as raw material of steel is no longer in the region although there were rich iron mines exploited by the Romans centuries ago. Currently the main five iron producer countries are China, Brazil, Australia, Russia and India so iron is likely to come from one of those countries. - Concrete. Spain is the first European producer of clinker, main component of cement. There are lots of loam, sand and gravel quarries as well, so concrete can be considered as a local product. - Bricks: made in Spain, where it is a common building material because of the fact that there are plenty of clay quarries. - Aluminium in windows. Although there are plenty of windows factories, there are not bauxite (a key component in aluminum production) in Spain. The main producer countries are Brazil, Jamaica and Australia.
