  1. 6. Pulp compositions and their influence on the production of dialcohol cellulose

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Viktoria Carlsson; [2020]
    Keywords : ;

    Abstract : The characteristics of products made from pulp can be modified through different methods. If the pulp is refined either laboratory or industrially, the fibres in the pulp become more flexible and therefore creates stronger bonds to each other, which results in a final product with a higher strength.

  3. 7. Gas Emissions from Contaminated Fibrous Sediments in Sweden

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Fredrik Collin; [2020]
    Keywords : Fiberbank; fibrous sediment; gas ebullition; GHG emissions; methanogenesis; optical ebullition sensor; Fiberbank; fibersediment; gas ebullition; växthusgas emissioner; metanogenes; optiska ebullitions sensore;

    Abstract : Gas Emissions from Contaminated Fibrous Sediments in Sweden The discharge of untreated wastewater from pulp and paper mills have resulted in the accumulation offibrous sediments on the bottom of many nearby aquatic recipients. Some accumulations are multiplemeters thick and consist almost entirely of cellulose fibre or wood chips; these are called fiberbanks. READ MORE

  4. 8. Design of multilayer paperboard for optimisedcompression strength

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Ali Salem Ali; [2020]
    Keywords : Compression strength; Paper; Cardboard; Dynamique Formette; Dynamic sheet former; SCT; Shortspan compression test; fibre; fibre properties; fiber; fiber properties; Multilayer;

    Abstract : This master thesis was issued by BillerudKorsnäs Gruvön. The focus of this thesis was theinvestigation of the effects different fibre types has on the compression strength of the whole paper product. This stems from wanting to better understand how to produce a better paperboard construction with respect to stacking, storage, and transport. READ MORE

  5. 9. Transparent paper: Evaluation of chemical modification routes to achieve self-fibrillating fibres

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

    Author : Paulina Sandberg Birgersson; [2020]
    Keywords : Transparent paper; nanopaper; nanocellulose; chemical modification of cellulose; cellulose nanofibrils CNF ; Transparent papper; nanopaper; nanocellulosa; kemisk modifiering av cellulosa; cellulosa nanofibriller CNF ; nanopapper;

    Abstract : Transparenta papper tillverkade av cellulosa nanofibriller (CNF), visar stor potential att kunna ersätta petroleumbaserade plaster inom många användningsområden, till exempel för mat- och varuförpackningar. CNF, även känt som nanocellulosa, kombinerar viktiga cellulosaegenskaper, med unika egenskaper hos nanomaterial. READ MORE

  6. 10. The biodegradable straw - Investigating how enzymes can be used to enhance desired product qualities of drinking devices.

    University essay from Lunds universitet/Innovation

    Author : Charlotte Parnefjord Gustafsson; Hanna Liang; [2020]
    Keywords : biodegradable; bioplastics; drinking devices; enzymes; fibre material; PHA; product design; statistical analysis; straws; Technology and Engineering;

    Abstract : The increasing production of single-use plastics negatively affects the climate. The resulting plastic ocean debris has fatal consequences to marine life. As a result, the European Parliament has placed a ban on single-use plastics by 2021, making it essential to study sustainable materials for single-use products such as straws. READ MORE
