  1. 1. Environmental System Analysis of Waste Management Experiences from Applications of the ORWARE Model

    Detta är en avhandling från Stockholm : KTH

    Författare :Anna Björklund; [2000]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; municipal solid waste MSW ; waste management; waste management planning; model; environmental systems analysis; life cycle assessment LCA ; substance flow analysis SFA ; substance flows; environmental impact; energy; uncertainty; TECHNOLOGY Chemical engineering; TEKNIKVETENSKAP Kemiteknik;

    Sammanfattning : Waste management has gone through a history of shiftingproblems, demands, and strategies over the years. In contrastto the long prevailing view that the problem could be solved byhiding or moving it, waste is now viewed as a problem rangingfrom local to global concern, and as being an integral part ofseveral sectors in society.

  2. 2. Diffuse emissions from goods influences on some societal end products

    Detta är en avhandling från Växjö : Linnaeus University Press

    Författare :Jennie Amneklev; Bo Bergbäck; Hans-Bertil Wittgren; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arsenic; bismuth; CCA-treated wood; copper; material flow analysis; silver; substance flow analysis; urban flows; Miljövetenskap; Environmental Science;

    Sammanfattning : End products of society (e.g. sewage sludge and incineration ashes) can be used as indicators of the use of chemicals in consumer goods. Through upstream work the sources of substances released from goods may be identified before the emissions reach the end products. LÄS MER

  3. 3. Tracing Copper from society to the aquatic environment Model development and case studies in Stockholm

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Qing Cui; Maria E. Malmström; Olle Wahlberg; [2010]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; diffuse source; source analysis; sediment pollution levels; urban lake; Copper; Stockholm archipelago; SFA; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Copper remains at elevated levels in the aquatic environment of Stockholm due to diffuse urban sources. Management of these diffuse sources requires their quantification but they cannot be measured directly by field observations. LÄS MER

  4. 4. Systems Perspectives on Modelling and Managing Future Anthropogenic Emissions in Urban Areas Nitrogen, Phosphorus and Carbon Studies in Stockholm, Sweden

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Jiechen Wu; Maria E. Malmström; Daniel Franzén; Daniel Müller; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Anthropogenic emissions; Urban development; Future; Substance flow analysis SFA ; DPSIR.;

    Sammanfattning : Managing anthropogenic emissions in urban areas is a major challenge in sustainable environmental development for cities, and future changes and increasing urbanisation may increase this challenge. Systems perspectives have become increasingly important in helping urban managers understand how different changes may alter future emissions and whether current management strategies can efficiently manage these emissions.

  5. 5. Sources and fluxes of organic contaminants in urban runoff

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Karin Björklund; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; alkylphenols; substance flow analysis; sediment; concentrations in urban matrices; urban runoff quality predictions; source identification; phthalates; stormwater; snow;

    Sammanfattning : Urban runoff quality is recognized as one of the most significant pressures on aquatic ecosystems worldwide. Research into pollutants in urban runoff has traditionally focused on nutrients, suspended solids and metals and consequently knowledge of anthropogenic organic pollutants is limited. LÄS MER
