1. 16. Development and Application of Methods based on DOAS and FTIR Absorption Spectroscopy for Atmospheric Research

   Författare :Bo Galle; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; open-path; nitrous oxide; DOAS; long-path absorption; landfill; methane; climate gases; ozone depletion; biogenic emissions; fugitive emissions; FTIR; ammonia;

   Sammanfattning : Over the past decades concern about the environmental impact on our atmosphere from human activities has been constantly increasing. From the recognition of local industrial pollution in the first part of this century, over regional scale problems related to urbanisation and growth of traffic systems to global environmental problems such as climate change and stratospheric ozone depletion.

3. 17. Landfill mining approach for resource recovery from glass dumps into the circular economy

   Författare :Richard Mutafela; William Hogland; Lennart Mårtensson; Linnéuniversitetet; []
   Nyckelord :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;

   Sammanfattning : 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.

4. 18. Methodology for evaluation of hazards from solid waste and landfill-generated leachate

   Författare :Britt-Marie Svensson; Lennart Mathiasson; Lennart Mårtensson; Ann-Sofi Rehnstam-Holm; Kenneth M. Persson; Högskolan Kristianstad; []
   Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Analytical protocol; organic pollutants; toxicity test; landfill leachate; leachate treatment; leaching test; waste acceptance criteria; Chemistry; Kemi; NATURAL SCIENCES; NATURVETENSKAP; leaching test; waste acceptance criteria.;

   Sammanfattning : A methodology based on an analytical protocol for evaluation of hazards from landfill leachate and solid waste is described. A dynamic analytical protocol, the LAQUA protocol, including measurements of inorganic and water-quality parameters, polar and non-polar organic marker compounds, and toxicity, was constructed.

7. 20. Developing strategies for improved economic performance and reduced climate impact of landfill mining in Europe

   Författare :John Laurence Esguerra; Joakim Krook; Niclas Svensson; Steven Van Passel; Anders Damgaard; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; waste management; landfill management; resource recovery; sustainability assessment; emerging concept;

   Sammanfattning : Landfill mining refers to the re-circulation of resources from the previously deposited wastes. It is an alternative approach for managing landfills that integrates resource recovery with site remediation. LÄS MER
