Sevilla needs some 3,259 kt of raw materials and other materials annually. The main entry point are imports, as local production is quite limited (607 kt). At internal urban circuit, it processes 1,750 kt in materials, of which 375 kt are added to the stock of buildings and urban equipment and the rest are destined for domestic consumption in the city. It manages to reinject 174 kt of secondary materials recovered from waste into its economic circuit.

Construction sector

The main conclusions from the Sankey diagram analysis are:

  • Virgin sand & gravel, Gypsum & Limestone and other stone material are easily available for concrete manufacturing and for construction of roads and buildings.
  • There are significant manufacture of bricks, metals and timber products in Seville and considerable parts of these are exported outside of the area.
  • However, other construction materials like aluminium, glass and insulation materials are imported to Seville.

According to the calculation illustrated in the Sankey diagram, all the data related to local CDW collection and treatment is not currently available. The municipal waste management company Lipasam only collects CDW from small producers and citizens throughout the "Clean points". Even almost the total amount of CDW collected by Lipasam is recycled, it shows a limited impact on the whole picture of the city. The greatest potential for developing the circular economy of the construction sector in the city is to utilise materials collected as waste in upcycled higher-value products, which could replace virgin materials in the construction sector.

There are still many assumptions behind the distribution of material flows visualised in the Sankey diagram. In the future, the information may be updated based on possible new and more detailed data.
