1. Evaluating the feasibility of chitosan as an adhesive for wood laminates and as a matrix for transparent wood
Master-uppsats, KTH/Fiber- och polymerteknologiSammanfattning : En av grundpelarna i alla hållbara system är införandet av en cirkulär ekonomi, som främjar återanvändning och återvinning av material. Plast är en av i utmaning i detta avseende på grund av den stora produktionsvolymen variation i sorter och långsamma nedbrytn. LÄS MER
2. Recovery of Dialcohol Cellulose using Micro- and Ultrafiltration Processes
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : The waste management and production of plastic play a concerning part in global warming and continues to have a negative effect on the environment. A promising strategy to address this challenge is to develop new sustainable materials, to replace current fossil-based plastics. LÄS MER
3. Chemical modification of starch in order to get thermoplastic properties
Kandidat-uppsats, KTH/MaterialvetenskapSammanfattning : 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. LÄS MER
4. 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
5. From Trash to Treasure : A Qualitative Study on Consumer Perception of Bio-based Plastics and the sspects that influence these perceptions
Master-uppsats, Uppsala universitet/Företagsekonomiska institutionenSammanfattning : This research study aims to explore consumer ́s perception of bio-based plastic and to gain a comprehensive understanding of the various aspects including knowledge, expectations, perceived behavioral control and subjective norms that influence these perceptions. With increasing environmental concerns related to conventional plastics, there is a growing interest in sustainable alternatives. LÄS MER
