  1. 21. Phosphorus : flows to swedish food chain, fertilizer value, effect on mycorrhiza and environmental Impact of Reuse

    Författare :Kersti Linderholm; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Phosphorus is an essential element for plants, animals and humans and is also a scarce resource as a raw material for fertilizer production. The flows of phosphorus to and from Swedish agriculture and food chain was investigated with a material flow analysis (MFA). LÄS MER

    Sammanfattning : Shikimic acid production using recombinant E.coli has been developed during the past 15 years due to the increased demand of this product, primarily as a starting material for the anti-influensa medicine Tamiflu?. A detailed metabolic analysis of a shikimic acid producing E. LÄS MER

  4. 23. Towards recycling of scarce metals from complex products

    Författare :Magnus Andersson; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; material flow analysis; Recycling; waste electrical and electronic equipment; scarce metal; end-of-life vehicle; WEEE; ELV; technological innovation system;

    Sammanfattning : Cars and electronic equipment have come to depend on materially complex designs and are drawing attention to issues around sustainable materials management. The dependence of these products and other applications on metals that can be considered scarce, has been brought into political and scientific focus. LÄS MER

  5. 24. Dynamics of aluminum use in the global passenger car system: Challenges and solutions of recycling and material substitution
