Abstract:
As part of a more circular economy, current attention on waste is shifting from land?lling towards the prevention, re-use and recycling of waste materials. Although the need for land?lls is decreasing, there are many land?lls around the world that are still operational or at the point of starting the aftercare period. With traditional aftercare management, these land?lls require perpetual aftercare at considerable cost due to monitoring and regular maintenance of liners. In an attempt to lower these aftercare costs, and to prevent that future generations become responsible for ?nding a sustainable solution of present day waste, the Dutch government takes action to explore the possibilities of sustainable land?ll management. A project was started to investigate whether the use of source-oriented treatment techniques (so-called active treatment) of land?lls can result in a sustainable emission reduction to soil and groundwater.
During the next decade, sustainable land?ll management is tested at three selected pilot land?lls
in the Netherlands. To enable this pilot testing and to determine its success after the experimental treatment period, a new methodology and conceptual framework was developed. The aim of this paper is to describe the development of the new methodology, and in particular the policy decisions, needed to determine whether the pilot experiments will be successful. The pilot projects are considered successful when the concentrations in the leachate of the pilot land?lls have suf?ciently been reduced and for longer periods of time and comply with the derived site-speci?c Environmental Protection Criteria (EPC). In that case, aftercare can be reduced, and it can be determined whether sustainable land?ll management is economically feasible for further implementation.
