1. 1. Qualitative Analysis of Chlorinated Paraffins in Recycled Plastics

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Solal GAUDIN; [2023]
   Keywords : Short chain Chlorinated Paraffins SCCP Medium chain Chlorinated Paraffins MCCP Long chain Chlorinated Paraffins LCCP Recycled plastics Qualitative analysis Bioaccumulation Long range transport Gas Chromatography – Mass spectrometry;

   Abstract : Described in many studies as dangerous for the environment and potentially carcinogenic for humans, Chlorinated Paraffins (CPs) are easily widespread due to their substantial production and use in different products. Previous studies reported the presence of CPs in different plastic polymers. READ MORE

3. 2. 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

4. 3. Sustainable Polymer Production: Investigating Synthesis and Copolymerization of Cyclic Ketene Acetals

   University essay from KTH/Kemiteknik

   Author : Soufian Bourraman; Stella Staffas; Adam Brandt; Simon Isaksson; [2023]
   Keywords : Monomers; polymers; radical; radical ring opening polymerization; polymerization; BMDO; MMA; MVL; MBL; comonomer; copolymer; rROP; sustainable; biobased; degradable; monomer synthesis; plastic; polyester; bulk; solution; NMR; FTIR; TGA; DSC; SEC; hydrolysis; molecular weight; diol; ester bonds;

   Abstract : The large amount of non-degradable plastic waste has become a significant environmental concern, leading to an increased need for degradable plastics. Here in, to create degradable polymers, polyesters were produced through radical ring opening polymerization using cyclic ketene acetals. READ MORE

5. 4. 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

6. 5. Paper vs Plastic: A comparative Life Cycle Assessment (LCA) of two flower packaging solutions

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Marianna Chatzopoulou; [2023]
   Keywords : Corrugated board; Greenhouse gas emissions; Life Cycle Assessment; Packaging; Plastic; Sustainable Development;

   Abstract : The concept of sustainability is currently a prominent topic of discussion within the field of packaging. In the context of numerous product manufacturing enterprises, the integration of sustainability principles into their operational framework is often perceptible to external observers solely through the packaging of the final product.
