6. Transport, degradation and immobilisation processes in a landfill
Sammanfattning : .... LÄS MER
7. Biogas generation in landfills : equilibria, rates & yields
Sammanfattning : Landfilling in "cells" has become more common in recent years. Different waste streams are guided to different cells, among which the biocell is a landfill designed for biogas production. In this thesis, the dependence of biogas generation on waste composition was investigated. LÄS MER
8. Development and Application of Methods based on DOAS and FTIR Absorption Spectroscopy for Atmospheric Research
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.

9. Enhancing the circular economy: Resource recovery through thermochemical conversion processes of landfill waste and biomass
Sammanfattning : Currently, the global economy looses a considerable amount of potential secondary raw materials from the disposed waste streams. Furthermore, the existing landfill sites that often do not have proper environmental protection technologies pose a long-lasting risk for the environment, which urge immediate actions for landfill remediations.

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