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. Distribution and chemical association of trace elements in incinerator residues and mining waste from a leaching perspective

   Author : Naeem Saqib; Mattias Bäckström; Stefan Karlsson; William Mayes; Örebro universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; trace elements; partitioning; fly ash; bottom ash; speciation; association; risk assessment; wood waste; incineration; mining waste; Chemistry; Kemi;

   Abstract : Incineration is a mainstream strategy for solid waste management in Sweden and all over the world. Improved knowledge and understanding about the distribution of trace elements (in ashes) during incineration, and how trace element partitioning respond to the changes in waste composition, are important in terms of combustion process optimization and plant efficiency.

5. 3. Landfills and glass dumpsites as future bank accounts of resources : waste characterization and trace elements extraction

   Author : Yahya Jani; William Hogland; Monica Odlare; Linnéuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Landfill mining; metals extraction; glass dumpsites; hazardous waste; chemical extraction; reduction-melting; Miljövetenskap; Environmental Science;

   Abstract : Environmental pollution and health threats as well as scarcity of raw materials, water, food and energy are among the main challenges our world are now facing. Simultaneously, landfills and open dumpsites still are the dominant global waste disposal option even with their long term environmental impacts in case of greenhouse gases and contaminated leachates.

6. 4. Weathering kinetics of sulphidic mining waste

   Author : Bo Strömberg; KTH; []
   Keywords : ;

   Abstract : The leaching of soluble metal contaminants from mining wasteis of great environmental concern, since it represents a threatto the surrounding aquatic environment. In this thesis,geochemical processes that contribute to the release of acidicmine drainage from waste rock are investigated. READ MORE

7. 5. Landfill mining approach for resource recovery from glass dumps into the circular economy

   Author : Richard Mutafela; William Hogland; Lennart Mårtensson; Linnéuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Resource recovery; landfill mining; hazardous waste; hydrometallurgical extraction; geophysical mapping; circular economy; Återvinning av resurser; gruvdrift; farligt avfall; hydrometallurgisk utvinning; geofysisk kartläggning; cirkulär ekonomi; Miljövetenskap; Environmental Science;

   Abstract : Landfills and open dumps have been the most cost-effective waste disposal option, resulting in over 500,000 landfills and dumps in the EU alone. They pose significant environmental and health threats due to emission of toxic gases and release of persistent contaminants to soil and groundwater, triggering a considerable global economic impact annually.
