1. 6. Chemical modification of starch in order to get thermoplastic properties

   University essay from KTH/Materialvetenskap

   Author : Emma Hallbert; Elsa Wadman; [2023]
   Keywords : thermoplastic starch; dialdehyde starch; schiff-base; imine chemistry; termoplastisk stärkelse; dialdehydstärkelse; schiffbas; iminkemi;

   Abstract : There are numerous advantages of replacing traditional non-biodegradable synthetic plastics with bio-based plastics. Starch is globally available, cheap, renewable, and biodegradable. However, starch has a poor product performance and is relatively difficult to process, as conventional melt processing techniques cannot be used. READ MORE

3. 7. Incorporation of Plasticizers through Refining into Wood Pulp : A Potential Route For Bio-based Thermoplastic Materials

   University essay from KTH/Materialvetenskap

   Author : Victor Eric Pierre Chartrain; [2023]
   Keywords : Cellulose; Paper; Plasticizer; Mechanical Refining; Cellulosa; Papper; Mjukgörare; mekanisk bearbetning;

   Abstract : 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. READ MORE

4. 8. Paper vs Plastic: A comparative Life Cycle Assessment (LCA) of two flower packaging solutions

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Marianna Chatzopoulou; [2023]
   Keywords : Corrugated board; Greenhouse gas emissions; Life Cycle Assessment; Packaging; Plastic; Sustainable Development;

   Abstract : The concept of sustainability is currently a prominent topic of discussion within the field of packaging. In the context of numerous product manufacturing enterprises, the integration of sustainability principles into their operational framework is often perceptible to external observers solely through the packaging of the final product.

5. 9. Bio-based resins for digital light processing : Mechanical and degradable properties

   University essay from KTH/Materialvetenskap

   Author : Moa Eklund; Amanda Olofsson Ribrant; [2023]
   Keywords : Digital Light Processing 3D Printing DLP ; Additive manufacturing; Bio-based; Polymer; Thermosets; Covalent Adaptable Networks CANs ; Recycling; Characterization.; Digital Light Processing 3D Printing DLP ; Additiv tillverkning; Bio-baserad; Polymer; Härdplast; Kovalenta Anpassningsbara Nätverk CANs ; Återvinning; Karaktärisering.;

   Abstract : Thermosets are appropriate materials for various applications due to benefits such as heat resistance and good mechanical properties. The disadvantages of traditional thermosets from a sustainable manufacturing perspective are that they are usually derived from fossil resources, and also have permanent cross-linked networks that are difficult to break, making them non-recyclable.
