1. 11. Novel materials from lignocellulosic sources- can they replace thermoplastics?

   University essay from KTH/Fiber- och polymerteknologi

   Author : Emmy Albinsson; Helina Tafesse Belachew; Jasmin Swaich; Hannah Juhlin; [2021]
   Keywords : Emulisonspolymerisation; Biobaserade plaster; Hållbarhet; Polymerer; Bearbetad halm; Kompositer; PISA-raft;

   Abstract : Plastic waste is a severe environmental problem in today's society which has been noticed and discussed during the last couple of years. A constant increase of production over the last decades hasled to a large amount of plastic waste ending up in oceans as microplastics. READ MORE

3. 12. PlaCo : The plastic collecting robot

   University essay from KTH/Mekatronik

   Author : Annie Persson; Johanna Bergsten; [2021]
   Keywords : Arduino; IR-sensor; marine debris; mechatronics; microplastics; ultrasonic sensor; Arduino; IR-sensor; marin nedskräpning; mekatronik; mikroplaster; ultraljudssensor;

   Abstract : The oceans are an essential global resource for all living organisms but especially for us humans. However, year after year we continue to neglect proper recycling of our waste, resulting in litter ending up in our oceans. The majority of said litter comes from single use plastic items. READ MORE

4. 13. Sustainable Decision-Making in the Fashion Industry : How to influence the fashion industry to adopt more sustainable packaging solutions

   University essay from KTH/Industriell ekonomi och organisation (Inst.)

   Author : Elin Enlund; Jennie Nilsson; [2021]
   Keywords : The fashion industry; sustainability; packaging; e-commerce; drivers; institutional logics; barriers; product development; decision-making; LCA; platform; B2B.; Modeindustrin; hållbarhet; förpackningar; e-handel; institutionella parametrar; barriärer; produktutveckling; beslutsfattande; plattform; B2B;

   Abstract : Today, the fashion industry is responsible for 4 per cent of the global greenhouse gas emissions in the atmosphere and 20-35 per cent of the microplastics in the ocean. It is thereby a highly debated industry when it comes to environmental sustainability. READ MORE

5. 14. Enhancing the degradation rate of microplastics and organizing a study visit about sustainability

   University essay from KTH/Lärande

   Author : Marianne Al-Ghorabi; [2020]
   Keywords : Accommodation; assimilation; Fenton reaction; microplastics; polypropylene; polystyrene; proximal development zone; study visit; visible light photocatalysis; zinc oxide nanorods; Ackommodation; assimilation; den proximala utvecklingszonen; Fenton reaktion; fotokatalys med synligt ljus; mikroplast; polypropalen; polystyren; studiebesök; zinkoxid nanorör.;

   Abstract : Microplastics take hundreds to thousands of years to degrade in nature, and pose a threat to the environment. A photocatalytical degradation method have been developed to take advantage of solar light to degrade microplastics, however it takes several months to degrade microplastics with the process.

6. 15. Limiting microplastic pollution from municipal wastewater treatment : A circular economic approach

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Jordy van Osch; [2020]
   Keywords : Microplastics; circular economy; wastewater treatment plant; resource recovery; Multi-criteria analysis;

   Abstract : The increasing amount of microplastics found in the environment have underscored the urgency to identify, develop and deploy scenarios in which municipal wastewater treatment plants (MWWTPs) limit the release of urban microplastics into the environment. Simultaneously, the global trend towards a circular economy has defined the conditions for these scenarios in relation to the water-energy- nutrient nexus. READ MORE
