  1. 1. Waste Textiles Bioprocessing to Ethanol and Biogas

    Författare :Azam Jeihanipour; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bioethanol; biogas; biorefinery; cellulose recalcitrance; cotton-based cellulose; enzymatic hydrolysis; pretreatment; recycling; waste textile; Resursåtervinning; Resursåtervinning; Resource Recovery;

    Sammanfattning : The work of the present thesis focused on conversion of the cellulosic part of waste textiles into biogas and ethanol, and its challenges. In 2009, the global annual fiber consumption exceeded 70 Mt, of which around 40% consisted of cellulosic material. LÄS MER

  3. 2. Pretreatment of cellulosic waste and high rate biogas production

    Författare :Solmaz Aslanzadeh; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biogas; Two-stage anaerobic digestion; N-methylmorpholine N-oxide NMMO pretreatment; Lignocelluloses; Textile waste; Biofuels; Resursåtervinning; Resource Recovery;

    Sammanfattning : The application of anaerobic digestion technology is growing worldwide, mainly because of its environmental benefits. Nevertheless, anaerobic degradation is a rather slow and sensitive process. One of the reasons is the recalcitrance nature of certain fractions of the substrate (e.g. LÄS MER

  4. 3. Industrial Management Models with Emphasis on Construction Waste

    Författare :Jan Stenis; Byggproduktion; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Commercial and industrial economics; ekonomisk politik; ekonomiska system; ekonomisk teori; Management of enterprises; Industriell ekonomi; Technological sciences; management; Företagsledning; Building construction; Teknik; Byggnadsteknik; Ekologi; Ecology; sustainable development; Polluter-Pays Principle; contribution margin analysis; cost benefit analysis; construction waste; Economic models; integrated industrial waste management; kontroll av utsläpp; Miljöteknik; Environmental technology; pollution control; Economics; Environmental Law; Morallära; Moral science; Miljömedicin; Environmental health; Miljörätt; economic theory; econometrics; economic systems; Nationalekonomi; ekonometri; economic policy;

    Sammanfattning : Increased attention is nowadays devoted to waste management. The objective of this work is to analyse how commonly known business economic models and methods, as well as the Polluter-Pays Principle, can be applied to waste management in general and to waste fractionation in particular, so as to facilitate environmental optimisation of industrial and construction waste fractionation.

  5. 4. Beyond Waste Management : Challenges to Sustainable Global Physical Resource Management

    Författare :Jagdeep Singh; Björn Frostell; Olga Kordas; Anju Singh; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sustainable global physical resource management; global waste management; systems thinking; life cycle thinking; planning framework; global environmental justice; circular economy; Industrial Ecology; Industriell ekologi;

    Sammanfattning : Current physical resource management (PRM) was investigated in a global perspective in this thesis, to gain a deeper understanding of its implications in a sustainability perspective. In particular, the main challenges to the current PRM system and the kinds of systemic changes needed for sustainable PRM were examined. LÄS MER

  7. 5. Revealing the potential of Nordic microalgae : turning waste streams into resources
