1. 1. The economics of residual waste : policies, price discrimination, and welfare

   Författare :Sef Meens-Eriksson; David Granlund; Runar Brännlund; Thomas Broberg; Raymond Gradus; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Waste economics; net social cost analysis; waste incineration; municipal waste policy; waste taxes; price discrimination; spatial competition; welfare effects; Economics; nationalekonomi;

   Sammanfattning : Paper [I]: In this study, a net social cost framework is applied to provide insights on policy issues relating to the cross-border trade in waste fuel. We estimate the net social cost of using imported waste fuel in a highly efficient combined heat and power plant (CHP) in a cold climate by considering both private costs and benefits as well as external costs related to energy production, alternative waste management and fuel transport.

3. 2. Reducing household waste : A social practice perspective on Swedish household waste prevention

   Författare :Mimmi Bissmont; Kerstin Sandell; Hans Bertil Wittgren; Malmö universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Sammanfattning : This thesis studies household waste prevention from a social scienceperspective. Swedish waste management is efficient in handling wastebut has not succeeded in reducing its quantities, even though theissue of waste prevention is being raised at both international andnational levels.

4. 3. Maturation of Clay Seals in Deep Bore Holes for Disposal of Radioactive waste : Theory and Experiments

   Författare :Ting Yang; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high-level radioactive waste; HLW; very deep borehole; VDH; disposal; saturation degree; water transport; maturation; model; shear strength; hydraulic conductivity; swelling pressure; homogenization; Geoteknik; Soil Mechanics;

   Sammanfattning : KBS-3 and very deep borehole (VDH) concepts are two major types of long-term geologicaldisposal methods for high-level radioactive waste (HLW) isolating from the biosphere. TheKBS-3V concept for isolating the HLW at the depth of 400-500 m, is the officially proposedoption in Sweden and has been the subject of considerable research in the past few decades,while the VDH concept was considered as an option in the 1950s but later became discouragedbecause of insufficient experience in drilling technology.

5. 4. The complexation of some radionuclides with natural organics : Implications for radioactive waste disposal

   Författare :Maria Nordén; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

   Sammanfattning : Natural organics like humic substances are important for the speciation, mobility and bioavailability of metals in the environment. This ability necessitates the investigation of what impact humic substances may have on radionuclides that accidentally can escape from radioactive waste repositories. LÄS MER

7. 5. Environmental politics and the enchantment of modernity : mercury and radioactive waste disposal in Sweden

   Författare :Ylva Uggla; Rolf Lidskog; Johan Hedrén; Örebro universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; environmental politics; mercury; radioactive waste; modernity; risk; sociologi; Sociology; Sociologi; Sociologi; Sociology;

   Sammanfattning : Current Swedish environmental policy embraces the notion of sustainable development and the discourse of ecological modernisation, both of which stress the role of modern institutions in environmental protection work. In pursuing ecological sustainability, the Swedish Government assigns importance to the issue of domestic, safe, final disposal of mercury and radioactive waste; responsibility for mercury and radioactive waste management must not be passed to future generations.
