1. 1. Fresh Perspectives on the Assessment of Sewage Sludge Management

   Författare :Robin Harder; Chalmers tekniska högskola; []
   Nyckelord :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;

   Sammanfattning : 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).

3. 2. Improved life cycle assessment of wastewater and sludge management with resource recovery

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

   Sammanfattning : 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. LÄS MER

4. 3. Improved methods and practices in life cycle assessment of wastewater and sludge management

   Författare :Sara Heimersson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wastewater treatment; Life cycle assessment; decision basis; biosolids; sewage sludge; environmental impact;

   Sammanfattning : Large amounts of municipal and industrial wastewater are treated each year in order to prevent negative consequences to human health and the environment. The treatment processes, directly or indirectly, give rise to environmental impact, but also offer several possibilities to recover resources. LÄS MER

5. 4. Phytostabilization of mine tailings covered with fly ash and sewage sludge

   Författare :Clara Neuschütz; Maria Greger; Lena Kautsky; Anthony R. Dexter; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ammonium; biosolids; cadmium; copper; energy crop; metal and nutrient leakage; nitrate; phosphate; phytoremediation; plant stress response; root exudates; zinc; Plant physiology; Växtfysiologi; växtfysiologi; Plant Physiology;

   Sammanfattning : Establishing plant communities is essential for the restoration of contaminated land. As potential cover materials, fly ash and sewage sludge can prevent formation of acid mine drainage from sulfidic mine waste. LÄS MER

7. 5. Sludge-derived char : utilisation as a metal sorbent in dilute wastewaters

   Författare :Ida Sylwan; Eva Thorin; Lena Johansson Westholm; Konrad Koch; Mälardalens universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sorption; adsorption; sludge; biosolids; metal; wastewater treatment; sorption; adsorption; slam; metaller; avloppsvattenrening; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : Metal concentrations in soil and water have increased since the Industrial Revolution, which may have negative health and environmental effects. Metal pollution occurs, for instance, in municipal wastewater, industrial wastewater, and stormwater. Concentrations are often low, due to dilution. A common technology for metal removal is sorption.
