  2. 1. Circularity Assessment of Water and Waste in Cities : A Proposed Framework for Sustainable Performance Evaluation using LCA and LCC

    Author : Kavitha Shanmugam; Venkata Krishna Kumar Upadhyayula; Mats Tysklind; Runar Brännlund; Brajesh Dubey; Umeå universitet; []
    Keywords : Life cycle assessment; life cycle costing; environmental externalities cost; sustainable city; circularity; wastewater treatment; organic waste; waste to energy; assessment framework; environmental science; miljövetenskap;

    Abstract : Urbanization is a global phenomenon, happening on a massive scale and at a rapid rate, with 68% of the planet’s population predicted to be living in cities by 2050 (UN-DESA, 2018). The sustainability of a city (Goal 11 of UN SDGs) undergoing rapid urbanization depends on its ability to maintain a low consumption of resources and materials at any given time (referred to as the urban metabolic rate), whilst simultaneously providing essential municipal services to its inhabitants, such as a water supply, wastewater treatment and solid waste management.

  4. 2. A Journey towards Sustainable Small Wastewater Treatment Systems in Low and Lower–Middle Income Countries

    Author : Claudia Cossio Grageda; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wastewater treatment system; local stakeholders; operation and maintenance; sustainability assessment; institutional dimension; EVAS tool EVAluation of Sustainability ; low and lower-middle income countries; sustainability indicators; resource recovery; performance assessment;

    Abstract : The sustainability of small wastewater treatment systems (WWTSs) in low and lower-middle income countries represents a challenge in terms of functionality and optimal performance in the ongoing effort to treat wastewater sufficiently to enable safe discharge or reuse. The reuse of wastewater is a common practice in these countries, especially where water resources are scarce. READ MORE

  5. 3. Performance Assessment of Wastewater Treatment Plants : Multi-Objective Analysis Using Plant-Wide Models

    Author : MAGNUS ARNELL; Ulf Jeppsson; Bengt Carlsson; Hans Bertil Wittgren; Diego Rosso; Industriell elektroteknik och automation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; benchmarking; BSM; samrötning; energieffektivitet; växthusgasutsläpp; livscykelanalys; matematisk modellering; avloppsvattenrening; benchmarking; BSM; codigestion; energy efficiency; greenhouse gases; life cycle assessment; mathematical modelling; wastewater treatment; benchmarking;

    Abstract : As the knowledge about anthropogenic impacts of climate change has grown, the awareness of the contributions from treatment of wastewater has widened the scope for wastewater treatment plants (WWTPs). Not only shall ever stricter effluent constraints be met, but also energy efficiency be increased, greenhouse gases mitigated and resources recovered. READ MORE

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

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

    Abstract : 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. 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
