1. 1. Prospects for standardisation of industrial PET plastics to support the transition towards a circular economy

   University essay from Lunds universitet/Miljö- och energisystem

   Author : Agnes Ström; [2024]
   Keywords : Standard; standardisation; industrial PET; polyethylene terephthalate; circular economy; plastic; Technology and Engineering;

   Abstract : Plastkonsumtionen har ökat markant över tid och har utvecklats till ett viktigt material i dagens samhälle, men med utmaningen att råvaran främst kommer från fossila källor. Användningen av plast är i linje med den linjära ekonomin och den så kallade slit-och-släng-kulturen, vilket bidrar till felaktig hantering av plastavfall och en ineffektiv användning av resurser.

3. 2. Development of a microfluidic device to study simultaneous crystallization in the LIBs recycling process

   University essay from KTH/Kemiteknik

   Author : Shefali Paresh Solanki; [2023]
   Keywords : Battery recycling; microfluidics; simultaneous crystallization; simulation; crystal technology; microfluidics experimental setup; Batteriåtervinning; mikrofluidik; simultan kristallisering; simulering; kristallteknologi; mikrofluidikexperimentuppställning;

   Abstract : Återvinning av litiumjonbatterier (LIB) är avgörande på grund av kritiska råmaterialreserver och miljöhänsyn vid kassering. Hydrometallurgisk LIB-återvinning, en framstående industriell teknik, står inför kostnadseffektivitets- och komplexitetsutmaningar. READ MORE

4. 3. Investigation of acidic chemical recycling of poly(acetal-ester)s

   University essay from Lunds universitet/Centrum för analys och syntes

   Author : Saga Vesterbacka; [2023]
   Keywords : Poly actetal-ester s; Chemical plastic recycling; Hydrolysis; Acidic degradation; Akestra; PHVT; Re-polymerization; Polymer technology; Chemistry;

   Abstract : Plastic recycling is a very relevant topic from both environmental and economic viewpoints. Chemical plastic recycling is a logical solution to the plastic problems, which shows the potential to reduce plastic waste and carbon emissions from burning the plastics. READ MORE

5. 4. A Circular Solution for Plastic Waste Within Healthcare : A fully implementable solution for creating a circular end-of-life option for plastic waste using chemical recycling

   University essay from KTH/Produktionsutveckling

   Author : Bharghav Ganesh; Iliass Temsamani; [2023]
   Keywords : ;

   Abstract : With a growing awareness of the environmental impacts associated with the disposal of healthcare plastic consumables through conventional end-of-life methods, such as landfilling and incineration, there is an increasing need to adopt more sustainable practices. This thesis explores the development of an alternative, circular economy-based solution to manage plastic waste generated by the healthcare sector, focusing on the identification of circular end-of-life strategies.

6. 5. 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.
