    Sammanfattning : In our society in the 21st century one of the greatest challenges is to provide raw materials to the industry in a sustainable way. This requires increased use of renewable raw materials such as wood. Wood is widely used in pulp, paper and textile industries and ongoing research efforts aim to extend the use of wood in e.g. LÄS MER

  3. 22. Pollutant profiles as tools for characterisation of environmental exposure

    Sammanfattning : This thesis is concerned with measurements of persistent organic pollutants (POPs) in environmental samples. The POPs consist of several groups of compound with many isomers, hence analysing POPs in a complex environment is a This thesis is concerned with measurements of persistent organic pollutants (POPs) in environmental samples.

  5. 24. Conjoint analysis as a tool for communication and corporate environmental decision-making

    Författare :Stina Alriksson; Tomas Öberg; Marianne Lindström; Högskolan i Kalmar; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; conjoint analysis; PLS; Cluster analysis; Communication; Environmental; Decision-making; Environmental engineering; Miljöteknik; Miljövetenskap; Environmental Science;

    Sammanfattning : Conjoint analysis has been used extensively in marketing, transportation and healthcare for the past 50 years. Since the mid-1990s, it has also been applied to an increasing number of environmental issues. In this thesis, conjoint analysis is applied to environmental objectives of the Swedish steel industry.

  7. 25. Environmental preferences among steel stakeholders

    Författare :Stina Alriksson; Marianne Henningsson; Carl-Erik Grip; Anders Roos; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; conjoint analysis; environmental communication; focus group; light weighting; PLS; preferences; Q-methodology; risk perception; steel; stakeholders; Miljövetenskap; Environmental Science;

    Sammanfattning : Emissions of carbon dioxide, dioxins, nitrogen oxides and particulate matter as well as use of non-renewable resources and energy are some important sustainability challenges for the Swedish steel industry. Much effort has been made, mainly by technical solutions, which to a high degree have decreased the emissions during the last 30 years. LÄS MER
