1. Incorporation of Plasticizers through Refining into Wood Pulp : A Potential Route For Bio-based Thermoplastic Materials
Kandidat-uppsats, KTH/MaterialvetenskapSammanfattning : Fibers are interesting materials alternative to replace conventional fossil-based plastics, as they are bio-based and do not lead to CO2 emissions. Due to their limited ductility, it is difficult to use them to make complex three-dimensional shapes. LÄS MER
2. Improvements in Energy Efficiency of Vacuum Dewatering of Greaseproof Paper : Simulation of a Triple Vacuum Suction Box in Laboratory Scale
Master-uppsats, Karlstads universitet/Avdelningen för kemiteknikSammanfattning : Vacuum dewatering of paper is a heavily energy expensive process, even more so for greaseproof paper, which is one of the main products at Nordic Paper Seffle AB. Due to this being such an energy demanding process, improvements in the vacuum dewatering could save massive amounts of energy. LÄS MER
3. Undersökning av mekaniska egenskaper hos sandwichelement av core-materialet Greenwood och ytskikt av papp : Styvhet, bärförmåga samt elementens beteenden vid belastning för olika tjocklekar på ytskikten
Uppsats för yrkesexamina på grundnivå, Karlstads universitetSammanfattning : Byggbranschens utsläpp av växthusgaser utgör en stor andel av Sveriges totala utsläpp. För att minska de byggrelaterade utsläppen är det på många fronter som byggbranschen behöver förändras och effektiviseras. LÄS MER
4. Mechanical properties of viscose filament : Made from recycled cotton textile and softwood dissolving pulp
Master-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)Sammanfattning : The textile industry is one of the largest industries in the world and it causes up to 10 % of the global greenhouse gas emissions. With large environmental issues of cotton- and oil-based textiles, other options are explored such as man-made fibers producing fibers like viscose and lyocell. LÄS MER
5. The impact of interface characteristics on the recyclability and repulpability of packaging material
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : The world is slowly moving towards a more environmentally friendly mindset and many companies, such as Tetra Pak® have followed this lead by producing more environmentally friendly products and developing better materials with less environmental impact. To accommodate these requirements, it is important that the package is recyclable. LÄS MER
