2. 1. Landfill Mining : Institutional challenges for the implementation of resource extraction from waste deposits

   Author : Nils Johansson; Joakim Krook; Mats Eklund; Myra Hird; Linköpings universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Landfill mining; recycling; mineral policy; institutions; transitions; mining.;

   Abstract : The overall aim of the thesis is to examine the institutional conditions for the implementation and emergence of landfill mining. The result shows that  current policy makes it difficult for landfill mining operators to find a market outlet for the exhumed material, which means that landfill mining may result in a waste disposal problem.

4. 2. Source, mobility and fate of critical Be, Bi, F and W from historical sulfidic-oxidic skarn tailings : Re-mining as remediation method?

   Author : Lina Hällström; Lena Alakangas; Olof Martinsson; Heather Jamieson; Luleå tekniska universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tillämpad geokemi; Applied Geochemistry;

   Abstract : There is a potential risk that geochemical cycles of several critical metals will be affected in the pristine environment, when mining of these metals increases to meet the demand in green technology. The identification of critical metals is based on the economic importance and vulnerability to supply restrictions. READ MORE

5. 3. Economics of Landfill Mining : Usefulness and Validity of Different Assessment Approaches

   Author : John Laurence Esguerra; Joakim Krook; Niclas Svensson; Steven Van Passel; Miguel Brandao; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Economic assessment; Uncertainty management; Landfill management; Landfill mining;

   Abstract : Landfill mining (LFM) is an alternative strategy to manage landfills that integrates remediation with secondary resource recovery. At present, LFM remains as an emerging concept with a few pilot-scale project implementations, which presents challenges when assessing its economic performance. READ MORE

6. 4. Reprocessing historical tailings for possible remediation and recovery of critical metals and minerals : The Yxsjöberg case

   Author : Jane Mwaba Mulenshi; Jan Rosenkranz; Saeed Chehreh Chelgani; Urs Peuker; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining waste; Historical tailings; Conceptual framework; Critical raw materials; Tungsten; Scheelite; Characterization; Mineral liberation analysis; Beneficiation; Reprocessing; Mineral Processing; Mineralteknik; Centrumbildning - Centrum för avancerad gruvteknik och metallurgi CAMM ; Centre - Centre for Advanced Mining Metallurgy CAMM ;

   Abstract : With increasing consumption of primary mineral resources, the generation of mining wastes has also increased thus requiring the mining industry to address the growing environmental concerns. Waste rock and tailings are potential secondary sources of critical raw materials currently in short supply in the European Union, but also a source for environmental issues like acid mine drainage.

7. 5. Environmental and economic conditions of landfill mining : The development and application of a systems analysis approach

   Author : Per Frändegård; Joakim Krook; Niclas Svensson; David Laner; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Landfill mining is a relatively unproven, still uncertain concept for extracting resources from landfills. Previous studies in the field have mainly focused on solving local environmental problems related to leaching and other landfill management issues, or characterizing the material composition of various landfills.
