  1. 16. 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

  3. 17. Exploring the sustainability potential of an algae-based wood adhesive : Comparative and explorative environmental life cycle assessment of algae- vs. formaldehyde- based adhesives for particleboard production

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Charlotte Rasche; [2020]
    Keywords : life cycle assessment; particleboard; bio-adhesive; wood-adhesive; bio-resin; algae; macroalgae; seaweed; kelp; formaldehyde; greener production; environmental impacts; biobased; design for the environment;

    Abstract : Adhesives used for wood composites such as particleboard are conventionally of petrochemical nature with formaldehyde as a base substance and represent a pain point in the industry due their toxic emissions. Consequently, adhesives are subject to an agenda to develop more benign, low-impact alternatives. READ MORE

  4. 18. Characterizing the pore structure of porous matrices using SEQ-NMR spectroscopy

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Ella Strömberg; [2020]
    Keywords : SEQ-NMR; diffusion NMR; resins; porous materials; pore structure; pore size characterization; diffusion NMR simulations;

    Abstract : Characterization of the pore structure is a crucial part in themanufacturing of porous media used for purification of biologicalpharmaceuticals. This project took place at Cytiva in Uppsala and aimedat optimizing a newly developed method in pore structurecharacterization called size-exclusion quantification NMR (SEQ-NMR). READ MORE

  5. 19. Effect of Induction-Heat Post-Curing on Residual Stresses in Fast-Curing Carbon Fibre Reinforced Composites

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Mercedes Amelia Bettelli; [2020]
    Keywords : Carbon Fibres Reinforced Polymer Composite; epoxy resins; cure behaviour; residual stress and shape distortions;

    Abstract : Manufacturing induced shape distortions is a common problem for composite materials. Due to the non-isotropic nature of carbon fibre reinforced polymers (CFRP) unavoidable deformations occur during part production. During fabrication of polymer composites, the material obtains its final shape at elevated temperatures. READ MORE

  6. 20. A review study of Bisphenol A : as an endocrine disrupting chemical in food contact material manufactured from polycarbonate and epoxy resin

    University essay from SLU/Department of Molecular Sciences

    Author : Emma Danielsson; [2020]
    Keywords : BADGE; Bisphenol A; dietary Exposure; endocrine disrupting chemicals; epoxy resins; estrogenic activity; food contact material; food packaging; migration; plastic food containers; polycarbonate;

    Abstract : Bisphenol A (BPA) is one of the worlds most produced chemicals. This compound is widely employed as an additive in polymers such as polycarbonates and epoxy resins in the manufacturing of plastics to provide transparency, rigidity and resistance to the resins. READ MORE
