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

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

    Sammanfattning : 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. LÄS MER

  3. 2. Urban water management : Modelling, simulation and control of the activated sludge process

    Författare :Mats Ekman; Bengt Carlsson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatic Control; Reglerteknik;

    Sammanfattning : During the last few decades, wastewater treatment processes in urban water management have become more and more efficient and complex. Several factors such as urbanization, stricter legislations on effluent quality, economics, increased knowledge of the involved biological, chemical and physical processes as well as technical achievements have been important incentives for the development of more efficient procedures for wastewater treatment plants.

  4. 3. Exploring the circular economy of urban organic waste in sub-Saharan Africa: opportunities and challenges

    Författare :Daniel Ddiba; Göran Finnveden; Elisabeth Ekener; Sarah Dickin; Cecilia Lalander; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biowaste; governance capacity; resource recovery; sub-Saharan Africa; sustainable sanitation; sustainable urban development; circular economy; Strategier för hållbar utveckling; Strategies for sustainable development;

    Sammanfattning : Globally, there is increasing awareness of the importance of applying circular economy principles to the management of organic waste streams through resource recovery. In the urban areas of sub-Saharan Africa which are going to host a significant part of population growth over the next three decades, this is especially relevant. LÄS MER

  5. 4. Can new treatment combinations make sewage sludge management more sustainable?

    Författare :Torben Bauer; Lale Andreas; Robin Harder; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Avfallsteknik; Waste Science and Technology;

    Sammanfattning : Treated sewage sludge is often reused as a fertilizer but several European countries are phasing out this option due to concerns about harmful substances in the sludge. Valuables in the sludge should still be recycled so the removal of the pollutants is necessary. LÄS MER

  7. 5. Chemicals in consumer products : Towards a safe and sustainable use

    Författare :Linda Molander; Christina Rudén; Sven Ove Hansson; Mattias Öberg; KTH; []
    Nyckelord :consumer products; articles; hazardous chemicals; risk management; chemicals regulation; REACH; substitution; regulatory toxicology; European Union;

    Sammanfattning : Health and environmental risks associated with emissions of hazardous chemicals from articles, including everyday consumer products such as clothes and toys, have become widely acknowledged internationally, particularly in the EU. This thesis contributes to new understandings of how these risks are currently managed within the EU and recommends actions for ensuring a safe and sustainable use of chemicals in articles. LÄS MER
