2012-3-1  Highlights We analyze two decades of landfill mining research regarding trends and topics. So far landfill mining has mainly been used to solve waste management issues. A new perspective on landfills as resource reservoirs is emerging. The potential of resource extraction from landfills is significant. We outline several key challenges for realization of resource extraction from landfills.
