A Resource Classification Framework for Old Landfills in Flanders (0.5 CEU)

Monday, September 25, 2017
14:45 – 15:15
Room 319

The project’s goal is to systematically provide information for the future management of more than 2,000 historic landfills in Flanders, using an evaluation procedure, previously developed in line with the UN Framework Classification for Fossil Energy and Mineral Reserves and Resources 2009 (UNFC-2009). Relevant material and energy flows are first quantified in a material flow analysis. A discounted cash flow analysis is performed to evaluate the socioeconomic viability of mining old landfills. Finally, the individual projects, where clean land and/or resources are recovered, are mapped onto the three UNFC-2009 axes “composition and extractable material content” (G-axis), “technical /project feasibility” (F-axis) and “socioeconomic viability” (E-axis). The Bornem project, involving land and resource recovery, yields a negative Net Present Value (NPV) of -17 Mio € (-44 €/t of excavated waste), therefore being currently not economically viable. The Turnhout case, a land development project by a private investor without any resource recovery, turns out to be economically viable with a NPV of 392,000 € (8 € /t of excavated waste). The Zuienkerke remediation project is at a too early stage to determine its socioeconomic viability.

Following the presentation, the audience will be able to:

  • Understand the relevance of resources recovered from old landfills in Belgium
  • Examine key drivers for landfill mining in Belgium
  • Compare different settings of landfill mining, e.g. a landfill’s composition, location and involved stakeholders
  • Evaluate and prioritize resource and land recovery projects for old landfills under economic and ecological aspects by using Material Flow Analysis and Discounted Cash Flow Analysis
  • Classify anthropogenic resources in line with the United Nations Framework Classification for Fossil Energy and Mineral Reserves and Resources 2009 (UNFC-2009), which had been originally designed for primary resources
