  1. 16. Substance flow analyses of metals and organic compounds in an urban environment : – the Stockholm example

    Författare :Nina Månsson; Bo Bergbäck; Stefan Anderberg; Högskolan i Kalmar; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; Miljökemi; Miljövetenskap; Environmental Science;

    Sammanfattning : The intensified use of materials, products and goods in our time involves massive consumption of metals and organic compounds that can be released from society to the environment in the various stages of production, use and waste. Depending on the circumstances this may give rise to environmental risks, as metals in general and certain organic substances may be toxic in the short or long term. LÄS MER

  3. 17. Sustainable Environmental Clean-up : Dynamic assessment for sustainable remediation of contaminated sites

    Författare :Mehran Naseri Rad; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; contaminated sites; sustainability assessment; remediation; multicriteria decision analysis; system dynamics; contaminant transport;

    Sammanfattning : Soil and groundwater contamination is an increasingly recognised threat to public health and the environment around the globe. New types of contaminants continue to emerge, and awareness of their threat, continues to develop. Many countries have national clean-up programs with priority lists of the most hazardous contaminated sites. LÄS MER

  4. 18. Land and climate effects of bioenergy - Brazilian sugarcane ethanol and combined biofuel-district heating in Europe

    Författare :Andrea Egeskog; Chalmers tekniska högskola; []

    Sammanfattning : According to the Intergovernmental Panel on Climate Change, use of fossil fuels is the largest source ofthe increase in atmospheric CO2. The second largest is land use change. To reach stringent climate targets,emissions from fossil fuel combustion and land use change will need to be reduced to near zerowithin a few decades. LÄS MER

  5. 19. Beyond Waste Management

    Författare :Jagdeep Singh; Internationella miljöinstitutet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sustainable global physical resource management; global waste management; systems thinking; life cycle thinking; planning framework; global environmental justice; circular economy;

    Sammanfattning : Current physical resource management (PRM) was investigated in a global perspective in this thesis, to gain a deeper understanding of its implications in a sustainability perspective. In particular, the main challenges to the current PRM system and the kinds of systemic changes needed for sustainable PRM were examined. LÄS MER
