  1. 1. Investigation of Milled Wood Lignin Extraction Using Enzymatic Hydrolysis for Application in Hydrophobic Barriers in the Food Packaging Industry

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Anna Wagne; [2023]
    Keywords : Lignin; extraction; hydrophobicity; chemical engineering; Technology and Engineering;

    Abstract : The objective of this report is twofold: to optimise the extraction method of lignin from spruce altering a few process parameters and to investigate the use of lignin as a hydrophobic barrier in food applications. The process used was STEX (steam explosion) pretreatment followed by enzymatic hydrolysis and MWL (milled wood lignin) extraction using a mixture of dioxane-water. READ MORE

  3. 3. 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.

  4. 4. Process simulation of HMF production from wheat bran and sugar beet pulp

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Matilda Petersson; [2021]
    Keywords : 5-hydroxymethylfurfural; Wheat bran; Sugar beet pulp; Process simulation; Aspen Plus; Biorefinery; Chemical engineering; Technology and Engineering;

    Abstract : Due to the progressing environmental problems related to global warming, the chemical industry is transitioning from fossil to renewable feedstocks. For added environmental benefits, surplus biomass from the agricultural industry which currently does not have any high-value applications can be used for production of chemicals. READ MORE

  5. 5. Potential of Steam Pretreated Jerusalem Artichok Stem for Ethanol Production

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Adam Eliasson; [2017]
    Keywords : SSF; Simultaneous Saccharification and Fermentation; Lignocellulose; Bioethanol; Second generation Bioethanol; Steam Explotion; Jerusalem Artichoke; Enzymatic Hydrolysis; chemical engineering; kemiteknik; Technology and Engineering; Chemistry;

    Abstract : To reach the goals set for the reduction of green house gas by the European Union the use of fossil fuels has to be reduced. To do this alternative fuels such as bioethanol have to substitute fossil fuels. READ MORE
