    Sammanfattning : The production of biofuels has increased in recent years, to reduce the dependence on fossil fuels and mitigate climate change. However, current production practices are heavily criticized on their environmental sustainability. LÄS MER

  3. 7. Industrial Symbiosis in the Swedish Forest Industry

    Författare :Anna Wolf; Mats Söderström; Magnus Karlsson; René van Berkel; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; forest industry; integration; industrial symbiosis; evaluation; human dimensions; MIND method; skogsindustri; integration; industriell symbios; utvärdering; implementering; MIND-metoden; Environmental engineering; Miljöteknik;

    Sammanfattning : Forskningen som presenteras i denna avhandling anknyter till forskningsfältet Industriell Ekologi och då särskilt den gren som kallas Industriell Symbios (IS). Inom IS förordas att ett företag kan öka produktionen och samtidigt minska resursanvändningen genom att effektivt integrera energi och materialflöden i ett större system. LÄS MER

  4. 8. Industrial Symbiosis for the development of Biofuel Production

    Författare :Michael Martin; Mats Eklund; Thomas Budde-Christensen; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biofuel; industrial symbiosis; biogas; ethanol; biodiesel; Environmental engineering; Miljöteknik;

    Sammanfattning : In recent years the popularity of biofuels has been transformed from a sustainable option fortransportation to a questionable and criticized method. Many reports have therefore beenproduced to view biofuel production from a life cycle perspective; though results may bemisleading. LÄS MER

  5. 9. Industrial Symbiosis - A Tool for More Sustainable Regions?

    Författare :Murat Mirata; Internationella miljöinstitutet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Technological sciences; Teknik; regional sustainability; distributed economies; Industrial ecology; Industrial symbiosis;

    Sammanfattning : Today's industrial systems are regarded to have unsustainable characteristics. In order to acquire a more sustainable state, fundamental changes are needed in the qualitative and quantitative aspects of the resource flows associated with such systems. LÄS MER

  7. 10. Signalling between plants and microorganisms

    Författare :Ulrika Troedsson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; symbiosis; Chitinase; rhizobium; mycorrhiza; plant; glucanase; Biology; Biologi;

    Sammanfattning : Plants and microbes can interact in several ways. Plants can be attacked by different types of pathogens like fungi, virus and bacteria, but can also form symbioses with fungi and bacteria. Certain common antimicrobial proteins are produced by the plants regardless of the type of microbial interaction with the plant. LÄS MER
