  1. 16. Extended Producer Responsibility for Closing Material Loops: Lessons from energy-efficient lighting products

    Författare :Jessika Luth Richter; Internationella miljöinstitutet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Extended Producer Responsibility; recycling; fluorescent lighting; waste management; Policy Evaluation; LEDs; WEEE Directive;

    Sammanfattning : The transition to a low-carbon economy requires enabling technologies including energy-efficient lighting products. It is increasingly recognized that a sustainable economy is not only low-carbon and energy efficient, but also resource efficient. LÄS MER

  3. 17. Anaerobic digestion of horse manure : renewable energy and plant nutrients in a systems perspective

    Författare :Åsa Hadin; Ola Eriksson; Karl Hillman; Nils Ryrholm; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Horse manure; horse keeping; anaerobic digestion; nutrient recycling; systems perspective; bedding; methane potential; feedstock; biogas; biofertilizer; Hästgödsel; hästhållning; rötning; näringsåterföring; systemperspektiv; strömaterial; metanpotential; biogassubstrat; biogas; biogödsel;

    Sammanfattning : In horse keeping horse manure is produced, which can be utilized as a fertilizer or considered a waste. Horse manure constitutes a resource in terms of both plant nutrients and energy. In addition energy policies and objectives aim at replacing fossil fuels with renewable energy sources. LÄS MER

  4. 18. Assessing the future environmental impact of lignin-based and recycled carbon fibres in composites using life cycle assessment

    Författare :Frida Hermansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; recycling; lignin; prospective; carbon fibres; environmental assessment; bio based; LCA;

    Sammanfattning : Carbon fibre reinforced polymers (CFRPs) are composite materials that are gaining attention for their lightweighting and strengthening properties in a wide range of applications. However, using them instead of conventional materials (such as steel or other composites) does not automatically lead to a decrease in life cycle climate impact or energy use. LÄS MER

  5. 19. Environmental assessment of incinerator residue utilisation

    Författare :Susanna Toller; Jon Petter Gustafsson; Dan Berggren Kleja; Erik Kärrman; Thomas H. Christensen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MSWI bottom ash; wood ash; recycling; LCA; environmental assessment; geochemical speciation modelling; dissolved organic matter; copper Cu ; Environmental engineering; Miljöteknik;

    Sammanfattning :  In Sweden, utilisation of incinerator residues outside disposal areas is restricted by environmental concerns, as such residues commonly contain greater amounts of potentially toxic trace elements than the natural materials they replace. On the other hand, utilisation can also provide environmental benefits by decreasing the need for landfill and reducing raw material extraction. LÄS MER

  7. 20. Towards sustainable solid waste management in Jordan

    Författare :Mohammad Aljaradin; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Solid Waste Management; Public Participation; Recycling; Landfilling; Jordan;

    Sammanfattning : Jordan is a country with a growing population that is undergoing rapid modernization. The increased volume of solid waste and associated logistical difficulties, the steady growth in the cost of waste management and the risk to human health are sources of concern. LÄS MER
