Landfill Mining Demonstration Project at Skaarup Landfill, Denmark

Convention Center

In 2016, the Danish EPA co-funded a landfill mining project at Skaarup Landfill, Renosyd (Denmark). The project was characterized as a demonstration project, and the aim was to excavate 5,000 tonnes of waste from the period 1979–1981, consisting of household waste, slaggs, construction and demolition material and domestic waste from both the private and public sector. The aim of the project was to examine the technical, economic and environmental benefits by doing excavation of waste and sorting previously landfilled material. The goal is to develop and implement an application-oriented tool to plan, select and implement future landfill mining projects at different types of landfills in Denmark and abroad. Before excavation, we test and use non-invasive screening techniques, a combination of georadar (GPR) og tracer-analyzes to get a three-dimensional picture of inside the landfill. We expect the method can give valuable input about the content of the waste composition inside landfills and be used as a method in the future to find new locations with high content of recyclables. We will develop a business model, to see how different aspects influence the economic and social benefits of landfill mining.

By attending this presentation, the audience will know about the benefits and barriers to landfill mining and also learn about the economics of landfill mining—both form this project but also from Danish experiences with landfill mining.
