LIFE ECO-SANDFILL’s goal is to demonstrate the technical and economic feasibility of using reclaimed Spent Foundry Sand (SFS) as an eco-friendly fine aggregate in construction applications, specifically for geotechnical applications such as embankments, mortars, and Controlled Low Strength Material (CLSM). Likewise, it will explore the options for high quality reutilization of treated SFS in foundry sector for core and mould making. The ultimate goal of the project is to reduce the large volume of foundry sand that is annually disposed of in landfills.

  • Sand impurities removal (such as metal scrap, oxidizable organic matter, fine content, pH…) with an efficiency over 90%.
  • Execution of construction works demos, substituting (100%) virgin fine aggregates with reclaimed SFS.
  • Validation of high quality reutilization of reclaimed sand in foundry as a substitute for new sand.
  • Valorization of more than 1500 t SFS in the Basque Country during the project.
  • A detailed financial cost-benefit analysis.
  • Lifecycle analysis of the new applications of SFS in construction.
  • Extrapolation of results to European Construction industry.
