  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

  2. 2. 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.

  3. 3. Study of a valorisation process for biomass industrial waste involving acid cooking and enzymatic hydrolysis

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Nicolas Brunet; [2020]
    Keywords : ;

    Abstract : Lignocellulosic biomass has potential to chip in the chemical and biofuels supplies in future societies,even though lignocellulose is a recalcitrant structure that has to be treated in several steps. After theirproper life cycle, wood-derived materials such as particleboards have few outcomes today apart fromenergy recovery for heat production. READ MORE
