Nordic & Baltic Course on Landfill Mining

Course in MSW and sludge landfill mining

Course Information

The PhD course of Landfill mining was divided in two parts, in June 2015. The first activity is part of a larger project that is co-financed by Swedish Institute, Linnaeus University (LNU), University of Lund (LU) and the company Sydvatten AB (Landfill owner of Rönneholms mosse). The Second part of the PhD course is part of a larger project that is co-financed by Swedish Institute and Estonian University (EMU). Both parts contain practical (field work) and theoretical studies.

Activity 1

Title: Mining in Sludge Landfill: characterization of sludge from drinking water treatment, metal extraction and recovery

Location: University of Lund. Sweden

Period: June 12–18. 2015

Credits: 2 ECTS

Target Group: National and international doctoral and master students from Sweden, Estonia, Ukraine, Latvia, Lithuania and Canada. In total 8 PhD-students and 3 professors was participating.

Practical (field work) studies: During the period 12 to 18 June 2015 an excavation of the sludge at the landfill ponds at Rönneholms mosse, Stehag was carried out. The aim of the project was to initiate trials to determine the mass balance of iron and aluminum in the sludge landfill ponds and develop best extraction method for metals (Al, Fe) and to explore the possibility of recovery of metals in the flocculation process at the waterworks Ringsjöverket.

Theoretical studies:

·         Welcome! Introduction and project description, schedule of project and the safety aspects.

Prof. Kenneth. M. Persson. LU. Sweden

·         Drinking water treatment in Sweden and history of Sydvatten, one of Sweden's largest drinking water producer.

Study visit Ringsjöverket (water treatment plant) and Rönneholms mosse (Sludge landfill). Stehag. Sweden

Prof. Kenneth. M. Persson. LU. Sweden and Lars Månsson. Sydvatten. Sweden

Activity 2

Title: Landfill Mining and waste characterisation.

Location: Tartu, Estonia

Period: 18-22, 2015.

Credits: 2 ECTS

Target Group: National and international doctoral and master students from Sweden, Estonia, Ukraine, Latvia, Lithuania, Brazil. In total 9 PhD-students and 2 professors was participating.

Practical (field work) studies: During period 18 to 22 June an excavation at Torma landfill, Estonia was carried out. Torma landfill is the first landfill in Estonia that was built according to European Union Landfill Directive. The aim of the study was to hand sort the excavated municipal solid waste, to classify the waste by size and material and to establish a material balance. In situ analyses on the sorted material were made on metal with XRF and on landfill gases. Currently further chemical analyses on the waste and leachate are in progress at participating universities in Sweden, Estonia, Ukraine and Latvia. 

Theoretical studies:

·        Leachate treatment, sewage treatment, potable water treatment in Torma Landfill

Video lecture on landfill Mining.

Prof. Mait Kriipsalu. EMU. Estonia

·        Video Extraction of metals with biological methods

Prof. Mark Dopsons. LNU. Sweden,

·        Test-assignment

Prof. Mait Kriipsalu. EMU. Estonia
