  1. 16. Environmental, Resource and Health Assessments of Hard Materials and Material Substitution: The Cases of Cemented Carbide and Polycrystalline Diamond

    Författare :Anna Furberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Life cycle assessment; polycrystalline diamond; disability-adjusted life years; material flow analysis; machining tools; cemented carbide;

    Sammanfattning : The conventional hard material used in manufacturing industry, cemented carbide (WC-Co), mainly consists of the geochemically scarce elements tungsten and cobalt. This use of scarce resources could potentially be avoided by a material substitution to the more abundant and largely carbon-based material polycrystalline diamond (PCD). LÄS MER

  3. 17. 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

  4. 18. Network Based Tools and Indicators for Landscape Ecological Assessments, Planning, and Design

    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Least-cost modeling; Functional connectivity; Environmental planning tool; Resilience; Spatial redundancy; Ecological integrity; Landscape Ecology; Graph Theory; Ecological Network Graphs; Biodiversity; Conservation Biology; Urban Planning; Regional Planning; EIA; SEA; Environmental Assessment; Ecological Indicator; Impact prediction; Habitat suitability; Species distribution; Urban ecology; GIS; Urbanization; Miljöbedömningsverktyg; Landskapsplanering; Resiliens; Ekologisk integritet; Landskapsekologi; Grafteori; Ekologiska nätverk; Biologisk mångfald; Bevarandebiologi; Urban planering; Regional planering; MKB; SMB; Miljöbedömning; Ekologisk indikator; Konsekvensbedömning; Habitatmodellering; GIS; Urbanisering; Nature conservation and landscape management; Natur- och landskapsvård; Environmental engineering; Miljöteknik; Terrestrial ecology; Terrestisk ekologi;

    Sammanfattning : Land use change constitutes a primary driving force in shaping social-ecological systems world wide, and its effects reach far beyond the directly impacted areas. Graph based landscape ecological tools have become established as a promising way to efficiently explore and analyze the complex, spatial systems dynamics of ecological networks in physical landscapes.

  5. 19. Livestock, feed production and land use – an environmental assessment

    Författare :Yaw Sasu-Boakye; Chalmers tekniska högskola; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; partial equilibrium modelling; land use impacts; livestock production; soya beans; life cycle assessments; ecosystem services; protein feeds; feed substitution;

    Sammanfattning : The use of land for agriculture contributes substantially to today’s global environmental challenges such as climate change, water and land degradation and biodiversity loss. Today, about 38% of the ice-free land surface on earth is used as agricultural land, with about 75% of agricultural land used to produce feed for livestock. LÄS MER

  7. 20. Environmental assessments of projects and local plans in the energy and waste sectors in Sweden : Practice and potential for improvement

    Författare :Sara Tyskeng; Mats Eklund; Lone Kørnøv; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental assessment; local planning; energy; waste; decision-making; Environmental engineering; Miljöteknik;

    Sammanfattning : Early perspectives on environmental issues have in general focussed on local pollution from specific sources. However, in past decades there has been a shift in society’s perspective on environmental management towards a focus on diffuse sources of pollution and long-term and global environmental issues.
