  1. 21. 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.

  3. 22. Characterisation of Poly(trimethylene carbonate) and f-BTI2g-TVTCN blends for the use in Biosensors

    University essay from KTH/Kemiteknik

    Author : Sara El Ghamri; Ed Kammeby; Herman Göransson; Arvid Stjerngren; [2023]
    Keywords : Bionedbrytbara biosensorer; Biodegradable biosenors; Organic mixed ionic–electronic conductors; Carboxyl esterase; organic electrochemical transistors; poly trimethylene carbonate ;

    Abstract : This report aims to study the degradation of poly(trimethylene carbonate) (PTMC) caused by the enzyme carboxylesterase in vitro. As well as to characterise polymer blends of f-BTI2g-TVTCN and poly(3-hydroxybutyric acid) as core components for organic electrochemical transistors (OETCs). READ MORE

  4. 23. Development and Optimization of Near-infrared spectroscopy

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Amanda Hahlin; [2023]
    Keywords : Near-infrared spectroscopy; NIRS; Textile sorting; Principal component analysis; PCA; Post-consumer end-of-life textiles;

    Abstract : With the growing demand for sustainable options, the existing sorting capacities are limiting the potential for fiber-to-fiber recycling. With the help of near-infrared spectroscopy (NIRS), automated sorting of textiles with high accuracy is possible due to the easy access for polymer identification. READ MORE

  5. 24. Robotic 3D Printing of sustainable structures

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Author : Tammam Alkhatib; [2023]
    Keywords : 3D printing; Robotic 3D printing; ABB Robotstudio; Robot simulation; Offline robot programming; 3DP PowerPac;

    Abstract : This bachelor thesis aims to integrate and evaluate a 3D printing robotic cell at the SmartIndustry Group – SIG lab at Linnaeus University (LNU).A sustainable structure consisting of wood fiber polymer composites was 3D printed withan industrial robot. Sustainable 3D printing material can be recycled or burned for energyafterwards. READ MORE

  6. 25. Prediction of Plastic Fragments in Recycled Paper Using Near-Infrared Spectroscopy

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Fidan Alieva; [2023]
    Keywords : Near-infrared spectroscopy; paper packaging; barrier materials; recycling; multivariate data analysis; Nära-infraröd spektroskopi; pappersförpackningar; barriärmaterial; återvinning; multivariat dataanalys;

    Abstract : Sustainability has gained a lot of attention in the field of research. Researchers and consumers both prioritize sustainability and environmental issues over previously dominant materials, such as plastic. Packaging and disposable items that used to be made of plastic have largely been replaced with paper. READ MORE
