16. A long journey from bioanode to biocathode
Sammanfattning : Better utilization of renewable sources of energy and recovery of resources from waste streams are important challenges for researchers. Bioelectrochemical systems (BESs) are new technologies which e.g. could be used to produce green energy from waste sources or store renewable electricity as chemical fuels. LÄS MER
17. Re-viewing industrial energy-efficiency improvement using a widened system boundary
Sammanfattning : Improved energy efficiency in industry is important for reaching the targets within the EU strategy for increased sustainability. However, energy efficiency is not always prioritised within companies, and the improvement potential remains large. This paradox called an energyefficiency gap is explained by energy-efficiency barriers. LÄS MER
18. Towards Prospective Exposure Modeling of Nanoparticles - Applying Particle Flow Analysis and Kinetic Exposure Modeling for the Cases of TiO2 and Ag Nanoparticles
Sammanfattning : The claims regarding the usefulness of nanoparticles (NPs) in different applications, such as wound dressings, solar cells and soil remediation, has been accompanied by concern that NPs may also pose risks to humans and to the environment. Considering the past century, when many substances later shown to cause unacceptable damage were manufactured in large amounts, there are reasons to thoroughly assess the risks of these NPs. LÄS MER
19. Organisational background to environmental impacts - Field study on housing management in Gothenburg
Sammanfattning : Today, there is a rich variety of technical solutions for environmental improvements of buildings. Nevertheless, the environmental performance of for example residential buildings has not been changed since the 1980s. Management initiative is needed for the introduction of technical solutions for environmental improvements. LÄS MER
20. Vindkraft, landskap och mening. En studie om vindkraft och människans rumsliga preferenser
Sammanfattning : The point of departure for this thesis is a core question in present-day environmental work, namely how to balance the conservation of nature against its utilisation. A wind power venture on a large scale energy production will, for instance, obviously have an impact on the natural scenery of the coastline. LÄS MER
