  1. 11. Modification of lignin derivatives for polymerization in water

    University essay from KTH/Ytbehandlingsteknik

    Author : Adrian Södergren; [2022]
    Keywords : biobased monomer; ferulic acid; radical polymerization; styrenic mononer; lignocellulose; biobaserad monomer; ferulsyra; radikalpolymerisation; styrenliknande monomer; lignocellulosa;

    Abstract : För att möjliggöra en hållbar utveckling skiftar många polymerforskares fokus just nu från att syntetisera polymerer från fossila resurser till att producera biobaserade polymerer från exempelvis träd. Av särskilt intresse är lignin, som utgör ungefär en tredjedel av allt växtmaterial men i nuläget oftast används som bränsle. READ MORE

  3. 12. Effect of substrate types on fermentation of mixed cultures to produce volatile fatty acids

    University essay from KTH/Industriell bioteknologi

    Author : Jayant Sehgal; [2022]
    Keywords : Mixed culture fermentation; Volatile fatty acids; Chemical oxygen demand; pH; starch; oil; gelatin; substrates; VFA production; Blandkulturjäsning; Flyktiga fettsyror; Kemiskt syrebehov; pH; stärkelse; olja; gelatin; substrat; VFA-produktion;

    Abstract : Innovativa teknologier, produkter och processer krävs på grund av marknadens ökande behov av bioprodukter med låga koldioxidavtryck. Idén att producera flyktiga fettsyror via biologiska processer, främst genom anaerob fermentering med blandkulturer, har återupplivats på grund av den omfattande exploateringen av oljeresurser.

  4. 13. Anaerobic Co-digestion of steam pretreated wheat straw and sewage sludge

    University essay from Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Author : Virginia Tosi; [2021]
    Keywords : Anaerobic co-digestion; wheat straw pretreatment; nutrients availability; OLR; VFA acumulation; Biotechnology; Technology and Engineering;

    Abstract : Anaerobic digestion (AD) of wastes and residues is a widely applied and explored process. However, when the process is not optimized, inadequate concentrations of nutrients and inhibitory compounds are common and can lead to low maximum organic loading rates and increased risk of process problems, low organic dry solids degradation rate and reduced methane yields.

  5. 14. Biomimetically improved materials comprising microfibrillated cellulose

    University essay from Umeå universitet/Kemiska institutionen

    Author : Cornelia Byström; [2021]
    Keywords : ;

    Abstract : Microfibrillated cellulose (MFC) is a renewable, cellulosic material mainly producedfrom wood fibers, which are found in the secondary cell walls of plant cells. With theincreased demand for renewable biopolymer films in packaging, MFC has emerged asa potential alternative to non-renewable polymer films. READ MORE

  6. 15. 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
