1. Tools for Evaluating Energy Efficiency of Steel Production : Lessons from Sweden and Europe
Sammanfattning : The European Union faces challenges related to climate change, security of energy supply, and competitiveness of European industries. Energy efficiency indicators are required for monitoring and controlling the effectiveness of policies such as the recently endorsed Energy Efficiency Directive. LÄS MER
2. Systems Analysis for Eco-Industrial Development : Applied on Cement and Biogas Production Systems
Sammanfattning : Our industrial systems are not sustainable—a major challenge which demands several types of responses. Eco-industrial development can be seen as such a response, with the goal to establish industrial systems that are both ecological and economical. Industrial Ecology is another closely related response. LÄS MER
3. 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
4. Pyrolysis of biomass in fluidized-beds: in-situ formation of products and their applications for ironmaking
Sammanfattning : The iron and steel industry emitted 8 % of all CO2 emissions in Sweden, 2011. Investigating alternative energy carriers is the purpose of this thesis. By pyrolyzing biomass, an energetic solid, gaseous and liquid (bio oil) fraction is obtained. LÄS MER
5. Alkaline by-products as amendments for remediation of historic mine sites
Sammanfattning : Mining has been and still is an important industry in Sweden, it has strongly contributed to the standard of living we have today. Extraction of ore began in the 12th century, but did not come about frequently until the 16th century, which is often seen as the starting age for ore processing and metal extraction. LÄS MER
