  1. 1. Data uncertinties in material flow analysis.Local case study and literature survey

    Författare :Lena Danius; KTH; []
    Nyckelord :data uncertainies; sensitivity analysis; material flow analysis; MFA; method to determine data uncertainties; case study; ComBox model; nitrogen flows;

    Sammanfattning : The aim of this thesis is to discuss and analyse the influenceof data uncertainties with regard to the reliability of materialflow analysis (MFA) studies. MFA, as a part of environmentalsystems analysis, is a method belonging to the research field ofindustrial ecology and more specifically industrial metabolism. LÄS MER

  3. 2. Environmental, Resource and Health Impacts of Hard Materials

    Författare :Anna Furberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MFA; life cycle assessment; material flow analysis; cemented carbide; disability-adjusted life years; LCA; DALY; hard metal; tire stud;

    Sammanfattning : The importance of hard materials for society is illustrated by the fact that entire historical time periods have been named after the predominant hard material used at that time. In the latest century, the introduction of the hard material cemented tungsten carbide with cobalt (WC-Co) has contributed to the economic growth we have seen and this material is crucial for the manufacturing industry of today.

  7. 5. Environmental Imprint of Human Food Consumption : Linköping, Sweden 1870 - 2000

    Författare :Tina-Simone Schmid Neset; Ulrik Lohm; Susanne Kytzia; Linköpings universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; food consumption; 19th and 20th century; Sweden; material flow analysis; MFA ; substance flow analysis; nitrogen; phosphorus; spatial imprint; lantbruk; miljöaspekter; livsmedelsindustri; livsmedelskonsumtion; markanvändning; Östergötland; 1800-talet; Food science; Livsmedelsvetenskap;

    Sammanfattning : Human food consumption has changed from the late 19th century to the turn of the millennium, and so has the need for resources to sustain this consumption. For the city of Linköping, situated in southeastern Sweden, the environmental imprint of an average inhabitant’s food consumption is studied from the year 1870 to the year 2000. LÄS MER
