  1. 1. Landfill Mining : Institutional challenges for the implementation of resource extraction from waste deposits

    Författare :Nils Johansson; Joakim Krook; Mats Eklund; Myra Hird; Linköpings universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; TEKNIK OCH TEKNOLOGIER; LANTBRUKSVETENSKAPER; SAMHÄLLSVETENSKAP; ENGINEERING AND TECHNOLOGY; AGRICULTURAL SCIENCES; SOCIAL SCIENCES; Landfill mining; recycling; mineral policy; institutions; transitions; mining.;

    Sammanfattning : The overall aim of the thesis is to examine the institutional conditions for the implementation and emergence of landfill mining. The result shows that  current policy makes it difficult for landfill mining operators to find a market outlet for the exhumed material, which means that landfill mining may result in a waste disposal problem.

  2. 2. Photonic crystals and photocatalysis : Study of titania inverse opals

    Författare :Delphine Misao Lebrun; Lars Österlund; Martyn Pemble; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; photocatalysis; titania; inverse opal; photonic crystal; optics; Engineering Science with specialization in Solid State Physics; Teknisk fysik med inriktning mot fasta tillståndets fysik;

    Sammanfattning : Due to an increase of human activity, an increase health risk has emerged from the presence of pollutants in the environment. In the transition to renewable and sustainable life style, treatment of pollutants could support the shifting societies. LÄS MER

  3. 3. Re-viewing industrial energy-efficiency improvement using a widened system boundary

    Författare :Svetlana Paramonova; Patrik Thollander; Mats Söderström; Stefan Grönkvist; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; SAMHÄLLSVETENSKAP; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; SOCIAL SCIENCES;

    Sammanfattning : Improved energy efficiency in industry is important for reaching the targets within the EU strategy for increased sustainability. However, energy efficiency is not always prioritised within companies, and the improvement potential remains large. This paradox called an energyefficiency gap is explained by energy-efficiency barriers. LÄS MER

  4. 4. Fighting flameless fires : Initiating and extinguishing self-sustainedsmoldering fires in wood pellets

    Författare :Ragni Fjellgaard Mikalsen; Vidar Frette; Bjarne C. Hagen; Ulrich Krause; Anne Steen-Hansen; Ulrich Krause; Nieves Fernandez-Anez; RISE; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; Fuel storage safety; Industrial fire; Biofuels; Smoldering; Extinguishment; Fire suppression; Fire growth; Fire spread; Heat transfer; Nonlinear dynamics; Complex systems; Combustion; Biomass energy; Synchronization; Oscillations; EMRIS;

    Sammanfattning : Smoldering fires represent domestic, environmental and industrial hazards. This flameless form of combustion is more easily initiated than flaming, and is also more persistent and difficult to extinguish. The growing demand for non-fossil fuels has increased the use of solid biofuels such as biomass. LÄS MER
