Tiivistelmä
The thesis observed the material composition of municipal solid waste (MSW) in
the new landfills at the Tarastenjärvi and Koukkujärvi waste centres, with a
specific focus on assessing the quantity of potentially recoverable metals.
Additionally, a theoretical process chart for landfill mining (LFM) was developed
to initiate a framework and define technological requirements for a streamlined
and effective metal extraction process.
Quantitative research methods were applied to acknowledge the mass and
material composition of landfilled MSW. Qualitative research methods were used
to identify the practical and cost-effective LFM techniques. Official waste statistics
and the MSW material composition data from the dry waste composition study
were the primary quantitative data sources in the thesis. Additionally, an
extensive literature review of relevant laws, LFM case studies and equipment
utilized in LFM projects was conducted to support the application of quantitative
data for LFM operations.
The overall contribution of the thesis was to provide Pirkanmaan Jätehuolto Oy
insights into the mass and material composition of landfilled MSW and to assess
the quantity of recoverable metals within the studied MSW. In addition to the
assessment of the quantitative data on landfilled MSW, the study provided
framework for the implementation of LFM project by outlining the process and
technological requirements for effective metal extraction.
