1. 26. The role of methane and hydrogen in a fossil-free Swedish transport sector

   Författare :Mårten Larsson; Per Alvfors; Stefan Grönkvist; Max Åhman; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; renewable transport fuels; biogas; methane; hydrogen; electrofuels; pyrolysis; well to wheel; transport policy; energy policy; Chemical Engineering; Kemiteknik;

   Sammanfattning : Drastic reductions of greenhouse gas emissions are required to limit the severe risks associated with a changing climate. One measure is to disrupt the fossil-fuel dependency in the transport sector, but it appears difficult and costly in comparison to other measures. LÄS MER

3. 27. System studies of the use of industrial excess heat

   Författare :Sarah Broberg Viklund; Magnus Karlsson; Mats Söderström; Semida Silveira; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; excess heat; waste heat; surplus heat; energy systems; greenhouse gas emissions; energy efficiency; energy policy; system studies;

   Sammanfattning : Energy, materials, and by-products, can be exchanged between companies, having positive effects in the form of improved resource efficiency, environmental benefits, and economic gains. One such energy stream that can be exchanged is excess heat, that is, heat generated as a by-product during, for example, industrial production. LÄS MER

4. 28. Policy Framework for Material Resource Efficiency : Pathway Towards a Circular Economy

   Författare :Leonidas Milios; Internationella miljöinstitutet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; resource efficiency; circular economy; policy studies; reuse; remanufacturing; recycling;

   Sammanfattning : The strategic direction of the European Union (EU) over the past twenty years has focused on increasing resource productivity and innovation in the economy, aiming at the efficient use and secured supplies of resources, economic growth and job creation, with fewer environmental impacts. One of the basic premises of the new ‘Green Deal’ for Europe is the promotion of the circular economy. LÄS MER

5. 29. Landfill Mining : Institutional challenges for the implementation of resource extraction from waste deposits

   Författare :Nils Johansson; Joakim Krook; Mats Eklund; Myra Hird; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Landfill mining; recycling; mineral policy; institutions; transitions; mining.;

   Sammanfattning : The overall aim of the thesis is to examine the institutional conditions for the implementation and emergence of landfill mining. The result shows that  current policy makes it difficult for landfill mining operators to find a market outlet for the exhumed material, which means that landfill mining may result in a waste disposal problem.

7. 30. Conditional Progress: Technical Rationality and Wicked Problems in Nuclear Waste Management

   Författare :Hannes Lagerlöf; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; nuclear waste management; science and technology studies; critical constructivism; sociology; technical rationality; reification;

   Sammanfattning : While various states and enterprises have produced nuclear power for decades, that is, demonstrated the functionality of the nuclear fuel cycle from uranium mining to power production, the waste that is simultaneously produced has been provisionally stored awaiting a safe solution. Still, no country has implemented such a solution. LÄS MER
