  1. 21. 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. 22. Using a GIS to enable an economic, land use and energy output comparison between small wind powered turbines and large-scale wind farms: the case of Oslo, Norway.

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Colin Potter; [2023]
    Keywords : Geography; GIS; Wind power; Renewable energy sources; urban wind energy; urban areas; planning; vertical axis wind turbines; comparative studies; urban integrated energy systems; Oslo; Roan; Earth and Environmental Sciences;

    Abstract : Responding to an identified knowledge gap, the study aims to determine if smaller wind turbines located on top of existing urban buildings are more resource efficient (land utilization and economically) than large scale wind farms. To answer this question, using a GIS, the resource efficiency of the Roan wind farm in Northern Norway was compared to a theoretical modeled installation of small-scale wind turbines on top of buildings within a 2km radius study zone in central Oslo.

  4. 23. Technical Aspects of Plant-based Protein Coagulation for Cheese Analogues

    University essay from SLU/Department of Molecular Sciences

    Author : Fardos Dana El Soudi; [2023]
    Keywords : Cheese analogues; Coagulation; Fava Bean; Plant-based; Protein; Soybean and Sustainability.;

    Abstract : This report highlights the importance of exploring alternative protein sources to produce sustainable and nutritious cheese analogues. Using legumes such as soybeans and fava beans can be a crucial step towards reducing our reliance on animal products. While also staying within the planetary boundaries, in line with the United Nations global goals. READ MORE

  5. 24. Monitoring Sustainability Performance during the Use Phase of Product-Service Systems

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Matilda Samuelsson; [2023]
    Keywords : Product-Service System PSS ; Sustainable Business Model; Use Phase; Assessment and Monitoring; Key Performance Indicators KPIs ; Produkttjänstsystem PSS ; Hållbar affärsmodell; Användningsfas; Bedömning och Kontroll; Nyckeltal KPI:er ;

    Abstract : Circular economy (CE) is widely seen as a potential solution to negative impacts caused by thelinear economy; however, companies must integrate CE principles into the business modeldeeper to achieve sustainable development. The Product-Service System (PSS) businessmodel is a potential solution to the superficial implementation of CE due to shifting the focusto delivering functionality rather than ownership. READ MORE

  6. 25. Varför bara M9? : alternativa grundstammar för hållbar äppelodling i Sverige

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Cecilia Appelquist; [2023]
    Keywords : Geneva; East Malling; MARK; B9; jordtrötthet; omplantering; tätplantering; fruktträdskräfta; blodlus; päronpest; rotröta;

    Abstract : I äppelodling används ympade träd, det vill säga träd som består av en ädelsort och en grundstam. I svensk kommersiell odling dominerar, enligt samtal med odlare innan arbetets start, grundstammen M9. Det finns dock ingen officiell statistik över vilka grundstammar som används. READ MORE
