  2. 1. Tourism Development in Resource Peripheries : conflicting and Unifying Spaces in Northern Sweden

    Author : Joakim Byström; Dieter K. Müller; Rikard Eriksson; Anna Dóra Sæþórsdóttir; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Tourism development; labor market transformation; related diversification; path dependence; resource periphery; pleasure periphery; Social and Economic Geography; kulturgeografi;

    Abstract : The northern Swedish inland is a sparsely populated area with a historical dependence upon natural-resource extraction. Therefore, this region has traditionally been defined as a resource periphery for extractive purposes. However, the rise of tourism challenges this narrative by producing a pleasure periphery for touristic purposes. READ MORE

  4. 2. Landfill mining approach for resource recovery from glass dumps into the circular economy

    Author : Richard Mutafela; William Hogland; Lennart Mårtensson; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Resource recovery; landfill mining; hazardous waste; hydrometallurgical extraction; geophysical mapping; circular economy; Återvinning av resurser; gruvdrift; farligt avfall; hydrometallurgisk utvinning; geofysisk kartläggning; cirkulär ekonomi; Miljövetenskap; Environmental Science;

    Abstract : Landfills and open dumps have been the most cost-effective waste disposal option, resulting in over 500,000 landfills and dumps in the EU alone. They pose significant environmental and health threats due to emission of toxic gases and release of persistent contaminants to soil and groundwater, triggering a considerable global economic impact annually.

  5. 3. On the resource efficiency of kraft lignin extraction

    Author : Jonas Kihlman; Lars Nilsson; Christer Gustavsson; Per Kristensson; Esa Vakkilainen; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Engineering; Kemiteknik;

    Abstract : Lignin is regarded as a promising raw material for the production of biobased products, such as chemicals, materials and fuels, and will most probably be a key component in future lignocellulosic biorefineries.This thesis examines the lignin extraction process in a kraft pulp mill, the technologies that are available for this purpose, and the impact made on the mill.

    Abstract : Wood biomass is an important resource in the development ofstrategies towards replacement of fossil-based materials. Woodcomprises cellulose, hemicelluloses and lignin, in amounts thatvary between species. READ MORE

  7. 5. Comparing Climate Forcers on a Common Scale

    Author : Erik Sterner; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Spatial-temporal Optimization; Carbon Cycle; Greenhouse Gases; Short-lived Climate Forcers; Upwelling-Diffusion; Metric; Energy Balance; Sea Level Rise; Non-cooperative Nash Equilibrium; Resource Extraction;

    Abstract : The climate is changing at a rapid pace. Through the United Nations Framework Convention on Climate Change (UNFCCC), the world has agreed to hold the on-going temperature increase below 2 °C. Climate change is caused by emissions of different atmospheric species (climate forcers). READ MORE
