  2. 6. Towards empirically grounded guidance for resource efficiency: Applying, developing and synthesising environmental assessments

    Author : Daniel Böckin; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Circular Business Models; guidelines; business models; synthesis; Life Cycle Assessment; decoupling; resource efficiency; 3D-printing; Circular Economy; waste hierarchy;

    Abstract : Numerous solutions have been proposed to mitigate environmental damage, including resource efficiency and the vision of circular economy. Suggested solutions are often formulated as guidelines and heuristics like in the EU waste hierarchy, so-called R-hierarchies for resource efficiency and various guidelines for circular business models.

  4. 7. Systems Analysis for Eco-Industrial Development : Applied on Cement and Biogas Production Systems

    Author : Roozbeh Feiz; Mats Eklund; Jonas Ammenberg; Olli Salmi; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; industrial ecology; eco-industrial development; multi-criteria analysis; life-cycle assessment; MCA; LCA; uncertainty management; systems analysis; industrial symbiosis; cement; biogas; cement production; biogas solutions;

    Abstract : Our industrial systems are not sustainable—a major challenge which demands several types of responses. Eco-industrial development can be seen as such a response, with the goal to establish industrial systems that are both ecological and economical. Industrial Ecology is another closely related response. READ MORE

  5. 8. From waste problem to renewable energy resource : exploring horse manure as feedstock for anaerobic digestion

    Author : Åsa Hadin; Ola Norrman Eriksson; Karl Hillman; Nils Ryrholm; Jaana Sorvari; Högskolan i Gävle; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; horse manure; environmental systems analysis; energy systems; renewable energy; environmental impact; anaerobic digestion; biogas; biofertilizer; systems perspective; bedding; incineration; composting; horse manure utilization;

    Abstract : A sustainable energy system requires, according to energy policies, reduced emissions of greenhouse gases, increased ratio of renewable sources of energy and more efficient use of energy. Horse manure could be regarded as waste, but also as a resource for renewable energy and plant nutrients. READ MORE

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

    Author : Frida Hermansson; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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. READ MORE

  7. 10. Towards Sustainable Shipping: Climate change and other environmental perspectives on carbon-based marine electrofuels and onboard carbon capture

    Author : Elin Malmgren; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; liquefied natural gas; power-to-X; methanol; power-to-gas; carbon capture and utilization; thematic analysis; Marine renewable energy; onboard carbon capture; marine fuels; LCA; shipping; electrofuels;

    Abstract : The global, local, and regional environment is under pressure from human activity. Shipping is a human activity causing emissions to air, water, and soil, which has direct and indirect effects on the environment. READ MORE
