This document provides an overview of a networking session on circular economy concepts and landfill mining. The session will include presentations on landfill mining situations across Europe and potential case studies from the UK and Hungary. Impacts of landfill mining on soil and from soil will also be discussed. Additional presentations will cover a circular economy approach, case studies of specific landfill mining and aggregate recycling projects, and applying circular economy concepts to the quarrying industry. The overall goals of the session are to address issues around huge amounts of waste, preserve non-renewable natural resources, and minimize negative environmental impacts through approaches like waste recycling, landfill mining, and exploiting waste as secondary raw materials.
