  1. 1. Reprocessing and Characterization of Polybenzimidazole for High-Temperature Polymer Electrolyte Membrane Fuel Cells

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Douglas Björkengren; [2023]
    Keywords : polymer electrolyte membrane fuel cells; PEMFC; HTPEMFC; polymer technology; polymer characterization; reprocessing; recycling; polybenzimidazole; PBI; Technology and Engineering;

    Abstract : A reprocessing method of poly(2,2’-(m-phenylene)-5,5’-bibenzimidazole) (PBI) membranes recovered from the production line of High-Temperature Polymer Electrolyte Membrane Fuel Cells (HT-PEMFC) at Blue World Technologies (BWT) has been developed in order to reduce material loss in the production. Redissolution of scrap PBI membranes in poly(phosphoric acid) (PPA) and phosphoric acid (PA) was successful and the subsequent washing procedure produced PBI that could be redissolved in N,N-dimethyl acetamide (DMAc) and suitable for solution casting of new membranes.

  3. 3. Method development and screening of extractable organofluorine (EOF) and targeted PFAS analysis in food packaging materials

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Nora Larsson; [2022]
    Keywords : Per- and polyfluoroalkyl substances PFAS ; Food packaging materials; Extractable organofluorine; Method development; Combustion ion chromatography; Targeted analysis;

    Abstract : Per- and polyfluoroalkyl substances (PFAS) have been manufactured and used in differentapplications for several decades, including food packaging materials. During the last 20 yearsthese compounds have been acknowledged as hazardous for humans and the environment, anddifferent regulations on PFAS have been established on both national and international levels.

  4. 4. End-Of-Life Wind Turbines in the EU : An Estimation of the NdFeB-Magnets and Containing Rare Earth Elements in the Anthropogenic Stock of Germany and Denmark

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Lisa Welzel; [2019]
    Keywords : rare earth elements; neodymium; dysprosium; wind turbines; permanent magnets; recycling; recovery; closing the loop; urban mining; sustainability; sällsynta jordartsmetaller; neodymium; dysprosium; vindturbiner; permanenta magneter; återvinning; cirkulärt system; hållbarhet;

    Abstract : Securing rare earth elements (REE) for a stable supply require sustainable management strategies in Europe due to a missing local primary production and a dependence on China as the main producer of REE. These elements, like neodymium (Nd) and dysprosium (Dy), are contained in permanent magnets (PM) (mostly NdFeB-magnets) in wind turbines. READ MORE

  5. 5. Exploring waste prevention possibilities through public procurement in public institutions -A case study from Bornholm, Denmark

    University essay from Lunds universitet/Internationella miljöinstitutet

    Author : Maria Amosa Diamara Jäppinen; [2019]
    Keywords : Waste prevention; dematerialisation; public institutions; public procurement; Bornholm; the EU; Business and Economics;

    Abstract : The thesis explored how waste could be prevented through public procurement in the public institutions on the Danish island, Bornholm. The island has set an ambitious vision, ‘Bornholm showing the way – without waste 2032’, aiming for 100 % waste recycling and reuse by 2032. READ MORE
