2. 1. Sustainable Sewage Sludge Management : Addressing Multidisciplinary Challenges

   Author : Torben Bauer; Lale Andreas; Elisabeth Wetterlund; Anders Lagerkvist; Anders Damgaard; Christina Dornack; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Avfallsteknik; Waste Science and Technology;

   Abstract : This PhD thesis focuses on multidisciplinary challenges in sewage sludge management and how they can be addressed to increase sustainability. Sewage sludge is the residual from wastewater treatment. It contains both resources and contaminants making its management challenging. READ MORE

4. 2. Fresh Perspectives on the Assessment of Sewage Sludge Management

   Author : Robin Harder; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; life cycle assessment; biosolids; land application; sewage sludge; pathogen risk; risk assessment; life cycle impact assessment; human toxicity; wastewater; chemical risks;

   Abstract : Sewage sludge management and its role in closing nutrient cycles have received considerable attention in recent years. This thesis quantified phosphorus flows in Gothenburg, Sweden, under current and possible future waste management practices, and aimed to improve the assessment of wastewater and sludge management from an environmental and human health perspective through blending risk assessment (RA) and life cycle assessment (LCA).

5. 3. Sludge from pulp and paper mills for biogas production : Strategies to improve energy performance in wastewater treatment and sludge management

   Author : Alina Hagelqvist; Thomas Nilsson; Karin M. Granström; Bengt Månsson; Bo Mattiasson; Thomas Welander; Karlstads universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; anaerobic digestion; pulp and paper mill sludge; methane production; energy efficient sludge management; Miljö- och energisystem; Environmental and Energy Systems;

   Abstract : The production of pulp and paper is associated with the generation of large quantities of wastewater that has to be purified to avoid severe pollution of the environment. Wastewater purification in pulp and paper mills combines sedimentation, biological treatment, chemical precipitation, flotation and anaerobic treatment, and the specific combination of techniques is determined by the local conditions.

6. 4. Flow-oriented studies for environmental management by local authorities : experiences from a regional substance flow analysis

   Author : Annica Lindqvist-Östblom; Linköpings universitet; []
   Keywords : flow-oriented studies; material flow analysis; substance flow analysis; interpretation; local authorities; regional authorities; environmental management; cadmium; sewage;

   Abstract : This thesis focuses on the issue of how to perform flow-oriented studies in order to become more useful for and adapted to local/regional authorities. Compared to traditional environmental monitoring and measurement of the state of the environment, flow-oriented studies are an attempt to broaden the approach to environmental concerns. READ MORE

7. 5. Improved life cycle assessment of wastewater and sludge management with resource recovery

   Author : Sara Heimersson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; allocation; LCA; sludge treatment; resource utilisation; sludge handling; biosolids; pathogen risks; wastewater treatment;

   Abstract : Around the world every day, large amounts of wastewater are treated before release, to avoid impacts on humans and the environment. The treatment requires resources in the form of energy and chemicals, and it generates large amounts of sewage sludge, however, it can also serve as a source of energy, nutrients and carbon. READ MORE
