1. 1. Analyzing Raw Material Characteristics for Composite and Bio-composite preparation and Assessing Environmental Impacts through LCA

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Lakshay Vashist; [2023]
   Keywords : Plastic; Polymers; Composites; Bio-composites; Synthetic Fibers; Natural Fibers; Mechanical Properties; Life Cycle Assessment LCA ; Plast; polymerer; kompositer; biokompositer; syntetiska fibrer; naturliga fibrer; mekaniska egenskaper; livscykelanalys LCA ;

   Abstract : With the population expected to grow dramatically in the future. The existing state of the ecosystem appears to be worse in the future. One of the key culprits that has been wreaking havoc on the ecosystem is the use of plastic that is used to produce composites. READ MORE

3. 2. Formulation and characterisation of novel edible-packaging for fruits and vegetables

   University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

   Author : Lola Sutton; Katerina Papa; [2023]
   Keywords : algae; edible packaging; carrageenan; cucumber; REL; oxidative stress; antioxidants; food engineering; Technology and Engineering;

   Abstract : This master's thesis investigated the potential of algae raw materials, specifically k-carrageenan and to a lesser extent alginate, as film-forming ingredients for the development of a novel edible packaging solutions. The project involved the testing and characterisation of several active ingredients of algal and plant origins both as extracts and as ingredients in films. READ MORE

4. 3. Risk assessment of non-intentionally added substances in polyester yarn made from recycled polyethylene terephthalate (PET)

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Kristina Arnqvist; [2023]
   Keywords : r-PET; polyester yarn; NIAS; risk assessment;

   Abstract : Polyester is a synthetic material made from polyethylene terephthalate (PET), which is synthesised from fossil raw materials. Many clothing manufacturers are using polyester in their clothing, which, from an environmental perspective, creates a non-sustainable cycle. READ MORE

5. 4. Evaluation of Woodmer/plastic composites

   University essay from KTH/Fiber- och polymerteknologi

   Author : Leon Ahlström; [2023]
   Keywords : Extrusion; Woodmer; Flame test; Tensile test; Composites; Extrudering; Woodmer; Flamtest; Dragtest; Kompositer;

   Abstract : Plast ger otroliga möjligheter i form av stor variation för materialanvändning. Tyvärr sker det dock på bekostnad av miljön då de ackumuleras i naturen. En kompromiss mellan hållbarhet och fortsatt plastanvändning skulle kunna vara att använda biomassa som fyllnadsmaterial i plastkompositer istället för plast. READ MORE

6. 5. Production of polymers from a papermills wastewater using HTC substrate. : Investigating the viability of using wastewater sludge from Skoghalls’ papermill in combination with filtrate from HTC of sewage sludge to produce biological plastic producing polymers.

   University essay from Karlstads universitet/Avdelningen för energi-, miljö- och byggteknik

   Author : Regan George; [2023]
   Keywords : PHA; HTC-substrate; Polymer;

   Abstract : Since their conception, plastics have been a dominant product due to the versatility of use, and readily available raw materials. However, the production and consumption of synthetic plastics have continued to increase over the years, leading to a significant rise in plastic waste and its associated environmental impacts, such as the detrimental effects plastic waste has on ecosystems, including the presence of toxic microplastics and risks to marine life, are becoming the focus of criticism.
