1. 1. Alkaline wet oxidation of biorefinery lignin from wheat straw

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Maja Lindblad; [2021]
   Keywords : alkaline wet oxidation; lignin oxidation; wheat straw; chemical pretreatment; biorefinery lignin; anaerobic digestion; response surface-modelling; chemical engineering; Technology and Engineering;

   Abstract : Climate change and depletion of fossil resources have generated a need for energy production based on renewable resources such as lignocellulosic biomass. Agricultural residues, like wheat straw, is lignocellulosic biomass that could contribute to the energy supply if it was used for biogas production. READ MORE

3. 2. CCS via Electrochemical CO2 Reduction to Ethylene-based Polymeric Construction Materials

   University essay from KTH/Kemiteknik

   Author : Christian Taylor; [2021]
   Keywords : CCS; Electrochemical CO2 Reduction; CO2 to Ethylene; Power-to-X; Polymeric Construction Materials; Circular Carbon Economy; Electrolysis; CO2 electroreduction; CCS; Elektrokemisk CO2-reduktion; Koldioxid till Eten; Power-to-X; Polymera konstruktionsmaterial; Cirkulär kolekonomi; elektrolys; CO2-elektroreduktion;

   Abstract : IPCC SR15 rapporterade att alla framtida scenarier för att begränsa klimatförändringen till 1,5°C är starkt beroende av negativa utsläppstekniker, såsom geografisk CO2-lagring som används av Stockholm Exergi’s Värtaverket. Men kan man uppnå starkare klimatvinster genom en cirkulär koldioxidekonomi? Bildandet av en cirkulär koldioxidekonomi är absolut nödvändigt för att uppnå global koldioxidneutralitet, men hur kommer vi dit? Elektrolys av CO2 erbjuder en ekonomiskt och miljömässigt attraktiv väg för att uppgradera CO2-utsläpp till värdefulla bränslen och råvaror, vilket minskar användningen av fossila resurser och CO2-utsläpp till atmosfären.

4. 3. Fibers and Textiles Produced from Chitin and Chitosan : A Literature Study For Different Production Methods

   University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Author : Doaa Hameed; Tamar Manouel; [2020]
   Keywords : chitin; chitosan; fibers; nanofibers; textiles; wound dressing; sutures; spinning;

   Abstract : Ökningen av världspopulationen har orsakat en ökad avfallsgenerering. Avfallet kan innehålla betydelsefulla ämnen, vilka kan användas som råvaror i många olika material och för olika ändamål. READ MORE

5. 4. Pre-acidification of a Synthetic Dairy Wastewater in Continuously Stirred Tank Reactors

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Can Xiong; [2019]
   Keywords : pre-acidification process; hydraulic retention time; soluble chemical oxygen demand transformation into fermentation product; volatile fatty acids; distribution; water engineering; environmental engineering; vattenförsörjningsteknik; avloppsteknik; Earth and Environmental Sciences; Technology and Engineering;

   Abstract : Two-stage anaerobic digestion is considered as a sustainable and efficient way to deal with dairy effluent, and is commonly applied. The pre-acidification happening during the first stage of this process could be used to buffer the complex conditions in the initial dairy effluent, as well as produce intermediary product such as volatile fatty acids (VFA), and it is essential to be controlled.

6. 5. Investigation of growth modes of the lithoautotrophic bacterium Cupriavidus necator

   University essay from Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

   Author : Raquel Perruca Foncillas; [2018]
   Keywords : applied microbiology; teknisk mikrobiologi; Technology and Engineering;

   Abstract : The microorganism Cupriavidus necator is a very interesting bacterium that has been established as a model microorganism for its capability to produce polyhydroxyalkanoates, more specifically polyhydroxybutyrate (PHB), a potential precursor/raw material for bioplastics. Lately, the scientific community has raised interest in the chemolithoautotrophic nature of C. READ MORE
