  2. 6. Natural resources and sustainable energy : Growth rates and resource flows for low-carbon systems

    Author : Simon Davidsson; Mikael Höök; Gert Jan Kramer; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; low-carbon technology; renewable energy; energy transitions; critical materials; energy metals; material flows; net energy; EROI; life cycle assessment; LCA; growth curves; curve fitting; resource depletion; Natural Resources and Sustainable Development; Naturresurser och hållbar utveckling;

    Abstract : Large-scale deployment of low-carbon energy technologies is important for counteracting anthropogenic climate change and achieving universal energy access. This thesis explores potential growth rates of technologies necessary to reach a more sustainable global energy system, the material and energy flows required to commission these technologies, and potential future availability of the required resources.

  4. 7. New biodegradable polymers from renewable resources

    Author : Yan Liu; KTH; []
    Keywords : ;

    Abstract : High molecular weight poly(ester-carbonate)s have beenprepared by a two-step chain-extension reaction performed onoligomeric αω-bishydroxyl-terminatedpoly(1,3-propylene succinate).αω-Bishydroxyl-terminated copolymeric oligomers of1,3-propylene succinate/1,4-cyclohexanedimethylene succinatewere obtained by thermal polycondensation of1,3-propanediol/1,4-cyclohexanedimethanol/succinic acidmixtures having different composition, and subsequently chainextended using phosgene as coupling agent, which leads toaliphatic/alicyclic copoly(ester-carbonate)s.

  5. 8. Four carbon oxychemicals from renewable resources

    Author : Adam Marschall Jaros; Christian Andersson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biokemisk processteknik; Biochemical Process Engineering;

    Abstract : Butanol, butyric acid and butyraldehyde are important 4-carbon oxychemicals typically generated from petro-chemical sources. All have significant markets in the food industry either for direct use as flavorings or as chemical feedstocks for generating butyric acid and butyraldehyde derived flavour compounds. READ MORE
