Landfills have historically been seen as the ultimate solution for storing waste at minimum cost. It is nowa well-known fact that such deposits have related implications such as long-term methane emissions,local pollution concerns, settling issues and limitations on urban development. Landfill mining has beensuggested as a strategy to address such problems, and in principle means the excavation, processing,treatment and/or recycling of deposited materials. This study involves a literature review on landfill miningcovering a meta-analysis of the main trends, objectives, topics and findings in 39 research paperspublished during the period 1988–2008. The results show that, so far, landfill mining has primarily beenseen as a way to solve traditional management issues related to landfills such as lack of landfill space andlocal pollution concerns. Although most initiatives have involved some recovery of deposited resources,mainly cover soil and in some cases waste fuel, recycling efforts have often been largely secondary. Typically,simple soil excavation and screening equipment have therefore been applied, often demonstratingmoderate performance in obtaining marketable recyclables. Several worldwide changes and recentresearch findings indicate the emergence of a new perspective on landfills as reservoirs for resourceextraction. Although the potential of this approach appears significant, it is argued that facilitating implementationinvolves a number of research challenges in terms of technology innovation, clarifying theconditions for realization and developing standardized frameworks for evaluating economic and environmentalperformance from a systems perspective. In order to address these challenges, a combination ofapplied and theoretical research is required.
