本研究旨在显示联合国资源框架分类(UNFC)如何帮助对具有不同成熟度的潜在垃圾填埋场采矿项目进行分类,从勘探到生产,根据技术,社会经济和项目规划方面。以法兰德斯的三个前垃圾填埋场为例,提供了有关旧垃圾填埋场未来管理的一般决策指南。使用ECLAR方法对人为资源(AR)进行评估(E)和分类(CL),个别项目,在回收干净的土地和/或材料的情况下,在三维UNFC系统下映射。Bornem项目,产生的净现值(NPV)为-17Mio€(-44€/吨挖掘废物),即该项目目前在经济上不可行。如果改变垃圾填埋场的关键参数,然而,未来经济开采的合理前景。事实证明,Turnhout土地开发在经济上是可行的,净现值为361,000欧元(8欧元/吨挖掘废物)。Zuienkerke补救项目还处于早期阶段,无法确定其社会经济可行性。比较和优先考虑法兰德斯潜在垃圾填埋场采矿项目的主要重点应该是(1)现场特定条件(例如垃圾填埋场的组成、土地价格),(2)项目相关因素(如需要补救与资源/土地恢复,选定的技术和项目设置,私人vs.公众评价视角)和(3)采矿的时机,考虑到未来成本的发展,价格,法律,可用的数据和信息。
This study aims at showing how the United Nations Framework Classification for Resources (UNFC) can help to classify potential landfill mining projects with different levels of maturity, from exploration to production, under technical, socio-economic and project-planning aspects. Taking the example of three former landfill sites in Flanders general decision making
guidelines regarding the future management of old landfills are provided. Using the ECLAR methodology for the evaluation (E) and classification (CL) of anthropogenic resources (AR), the individual projects, where clean land and/or materials are recovered, are mapped under the three-dimensional UNFC system. The Bornem project, yields a negative Net Present Value (NPV) of -17 Mio € (-44 €/t of excavated waste), i.e. the project is currently not economically viable. In case of changing key parameters the landfill has, however, reasonable prospects for future economic extraction. The Turnhout land development turned out to be economically viable with a NPV of 361,000 € (8 €/t of excavated waste). The Zuienkerke remediation project is at a too early stage to determine its socioeconomic viability. The main focus to compare and prioritize potential landfill mining projects in Flanders should be on (1) site specific conditions (e.g. landfill\'s composition, land prices), (2) project related factors (e.g. remediation required vs. resource/land recovery, selected technologies and project set-ups, private vs. public evaluation perspective) and (3) the timing of mining, considering future development of costs, prices, laws, available data and information.
