  1. 1. Användning av kalvningssystem i svensk dikalvsproduktion

    University essay from SLU/Department of Biosystems and Technology (from 130101)

    Author : Julia Ancher; [2023]
    Keywords : diko; dikalvsproduktion; kalvningssystem; skötselrutiner kring kalvning; djurvälfärd;

    Abstract : Dikons uppgift är att föda upp friska kalvar som växer och producerar bra kött. Inhysning och skötselrutiner kring kalvning är därför en central del dikalvsproduktionen för att ge kalven en bra start i livet. READ MORE

  3. 2. 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

    Abstract : För att säkra vår matproduktion i framtiden står vi inför utmaningar och ett behov av att skapa mer cirkulära system. Det här arbetet inkluderar biokol och svampodling, två branscher på framkant för att skapa mer cirkularitet, gynna matproduktionen och erbjuda alternativa näringskällor. READ MORE

  5. 4. Research on the Hydrothermal Conversion of Xylose Catalysed by CO2-H2O into Furfural

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Robert Liao; [2023]
    Keywords : ;

    Abstract : Agricultural waste treatment and carbon dioxide emissions from fossil fuel combustion have been critical challenges for sustainable development. This work is part of a study on converting straw into biofuels, which involves using xylose as the material, carbon dioxide (CO2) as the catalyst, and water (H2O) and Gamma-Valerolactone (GVL) as the solvent to produce furfural through hydrothermal conversion.

  6. 5. Increase of biogas production by incorporating residual streams from agriculture

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Stephanie Fjäll; [2022]
    Keywords : Anaerobic digestion; Agricultural residue; Lignocellulosic biomass; Mechanical pretreatment; Biogas production; Biorefinery; Chemical engineering; Agriculture and Food Sciences; Technology and Engineering;

    Abstract : To expand the biogas production in Region Västra Götaland (RVG), residual streams from the agricultural sector can function as a large-scale supplier of biomass. The production of biogas decreases the dependence of fossil fuels and the digestate that is formed can also be returned to the agricultural sector, creating a closed loop. READ MORE
