1. Local and global contaminants in Swedish waters : studies on PCBs, DDTs, 4,5,6-trichloroguaiacol and their transformation products in fish and sediments
Sammanfattning : This thesis is focused on studies on the environmental fate and methodological improvements for determination of the global contaminants, PCBs and DDTs, and locally discharged phenolics, e.g. 4,5,6-trichloroguaiacol (4,5,6-TCG), and their transformation products. LÄS MER
2. Improved Energy Efficiency and Fuel Substitution in the Iron and Steel Industry
Sammanfattning : IPCC reported in its climate change report 2013 that the atmospheric concentrations of the greenhouse gases (GHG) carbon dioxide (CO2), methane, and nitrous oxide now have reached the highest levels in the past 800,000 years. CO2 concentration has increased by 40% since pre-industrial times and the primary source is fossil fuel combustion. LÄS MER
3. Drömmar om något bättre : Om managementmodeller, mätningar och människor
Sammanfattning : For several years I have, from a management control perspective, followed the development and application of several popular management models, for example, the knowledge management, balanced scorecard, and intellectual capital models. This thesis, comprising four papers and an extended covering paper, contributes to the management control field by discussing and problematizing management models and how they describe humans by means of measurement.

4. Evaluating the utilisation of industrial excess heat from an energy systems perspective
Sammanfattning : Sweden aims to achieve climate neutrality by 2045. The need to immediately reduce greenhouse gas emissions in order to achieve climate targets affects industry directly. The pulp and paper sector is responsible for more than 50% of industrial energy use in Sweden. LÄS MER
5. System studies of biogas production : comparisons and performance
Sammanfattning : Biogas has the potential to be part of the transition towards a more sustainable energy system. Biogas is a renewable energy source and can play an important role in modern waste management systems. Biogas production can also help recirculate nutrients back to farmland. LÄS MER
