  1. 16. Anaerobic Co-Digestion Of Food Waste And Kraft Pulp Fibre To Enhance Digestate Dewaterability

    University essay from Linköpings universitet/Tema Miljöförändring

    Author : Kwame Boateng Agyemang; [2021]
    Keywords : Anaerobic digestion; Digestate; Dewaterability; Food waste; Pulp fibre;

    Abstract : Digestate produced during anaerobic digestion of food waste is recognised as a good alternative to mineral fertilizer which could also be used to amend soil properties. This has conventionally been applied directly and unprocessed to nearby farms or processed and transported elsewhere. READ MORE

  3. 17. Thermally insulating carbon foams from carbonized kraft lignin

    University essay from KTH/Fiber- och polymerteknologi

    Author : Isabelle Hernodh Svantesson; [2021]
    Keywords : Carbon foams; thermal insulation; kraft lignin; carbonization; thermal conductivity; Kolskum; värmeisolering; kraftlignin; karbonisering; värmeledningsförmåga;

    Abstract : Kolmaterial, såsom kolfibrer och kolskum, används som värmeisolatorer i applikationer vid höga temperaturer. För närvarande härleds dessa material från fossilbaserade källor, vilket tyder på ett behov av att hitta alternativa kandidater baserade på förnybara källor. READ MORE

  4. 18. Valorization of lignin for material applications

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

    Author : Filippa Winkvist; [2021]
    Keywords : microwave-assisted extraction; lignin; LCC; PLA; Pine; mikrovågsassisterad extraktion; lignin; LCC; PLA; tall;

    Abstract : Lignin är, med undantag för cellulosa, den av de naturliga polymererna det finns mest av på jorden och den ledande källan till fenolföreningar. De träväxterna som existerar idag, innehåller ca 30 % av just denna biopolymer. READ MORE

  5. 19. Raman Spectroscopy for Characterizing Porous carbon

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Author : Rima Zuriah Amdani; [2020]
    Keywords : Raman Spectroscopy; Porous Carbon; Biochar; Carbonization; Aromaticity; Physics and Astronomy; Technology and Engineering; Chemistry;

    Abstract : Porous carbon obtained from low cost and abundant biomass has gained attention as renewable material feedstock. In this study, porous carbon biochar produced through pyrolysis was investigated by Raman spectroscopy to disclose the structural properties. READ MORE

  6. 20. Development of magnetic lignin nanoparticles from low-molecular-weight eucalyptus and spruce lignin fractions

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

    Author : Anna Wessén; Eliot Diklev; Lejla Al-Tamimi; [2020]
    Keywords : Magnetic nanoparticles; Hardwood; Softwood; Self-assembly; Lignin;

    Abstract : Lignin is one of the most common biopolymers in the world. Together with cellulose andhemicellulose it constitutes the fibers in the wood. It has a high molecular weight due to its complexstructure consisting of crossed-linked phenolic monomers and is concatenated with different types ofcarbon and ether bonds. READ MORE
