  1. 1. Violent natural resource conflicts : From definitions to prevention

    Författare :Marie K. Schellens; Belyazid Salim; Stefano Manzoni; Silja Bára Ómarsdottir; Päivi Lujala; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Natural resource conflicts; natural resources; violent conflict; criticality; definition; predictive modelling; early warning; causal network; prevention; Physical Geography; naturgeografi;

    Sammanfattning : General scientific consensus is growing that natural resources play an important role in violent conflicts. Both scarcity and abundance contribute to violent conflict, depending on the socio-economic and political conditions at play. LÄS MER

  2. 2. Resource and Environmental Impacts of Resource-Efficiency Measures Applied to Electronic Products

    Författare :Hampus André; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; scarce metals; life cycle assessment; resource-efficiency; electronic products; resource depletion; circular economy; metal resource use;

    Sammanfattning : Natural resources such as ecosystems, land, water and metals underpin the functioning of economies and human well-being, and are becoming increasingly scarce due to growth in population and affluence. Metals are increasingly demanded for their specific properties as modern technology develops. LÄS MER

  3. 3. Assessing Mineral Resource Scarcity in a Circular Economy Context

    Författare :Hampus André; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; resource-efficiency; area of protection - natural resources; electric and electronic equipment; supply risk; scarce metals; criticality assessment; material flow analysis; life cycle assessment; circular economy; complex products;

    Sammanfattning : Due to humanity’s dependence on metal resources there are growing concerns regarding impacts related to their potential scarcity, both for current and future generations. The vision of a more circular economy suggests that extending the functional use of metals through measures aiming for resource-efficiency (RE) such as increasing technical lifetime, repairing and recycling could reduce mineral resource scarcity.

  4. 4. Natural resources and sustainable energy : Growth rates and resource flows for low-carbon systems

    Författare :Simon Davidsson; Mikael Höök; Gert Jan Kramer; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; low-carbon technology; renewable energy; energy transitions; critical materials; energy metals; material flows; net energy; EROI; life cycle assessment; LCA; growth curves; curve fitting; resource depletion; Natural Resources and Sustainable Development; Naturresurser och hållbar utveckling;

    Sammanfattning : Large-scale deployment of low-carbon energy technologies is important for counteracting anthropogenic climate change and achieving universal energy access. This thesis explores potential growth rates of technologies necessary to reach a more sustainable global energy system, the material and energy flows required to commission these technologies, and potential future availability of the required resources.

  5. 5. Resource efficient products in a circular economy – The case of consumables. From environmental and resource assessment to design guidelines

    Författare :Siri Willskytt; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; product characteristics; circular product design; resource efficiency; LCA; consumable products; ecodesign; design guidelines; circular economy;

    Sammanfattning : The circular economy (CE) is a concept to challenge the unsustainable production, consumption, and waste management of products, through the recirculation of resources and products through various means while reducing environmental impact. Within this concept, many measures are recommended for reducing environmental impact and resource use. LÄS MER
