  1. 6. Långsiktig torvnedbrytning för olika vegetationstyper på dikad skogsmark

    University essay from SLU/School for Forest Management

    Author : Carl Carlsson; Sofie Jönsson; [2023]
    Keywords : växthusgaser; torvmark; dikning;

    Abstract : Skogsklädda torvmarker i Sverige dikades i stor utsträckning mellan 1930- och 1980-talen i syfte att höja virkesproduktionen. Till följd av klimatproblemet har intresset för dikade torvmarkers bidrag till växthusgasutsläppen ökat under de senaste decennierna. READ MORE

  3. 7. 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.

  4. 8. Microgrid in George Washington, Cuba

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Mimmi Fröjdh; Sofia Sjöberg; [2023]
    Keywords : Cuba; microgrid; energy systems modelling; renewable energy; optimization; Kuba; microgrid; energisystemmodellering; förnybar energi; optimering;

    Abstract : Cuba has vast natural resources for domestic renewable energy generation, but their energy mix is heavily dominated by fossil fuels. This contributes to a high dependence on expensive oil imports and has led to significant generation shortfalls, which in turn has resulted in extensive power outages and serious fuel crises.

  5. 9. Techno-economic and environmental analysis of alternative pathways for urea fertilizer production.

    University essay from Linköpings universitet/Industriell miljöteknik

    Author : Wilson Rodriguez; [2023]
    Keywords : Urea fertilizer; ammonia; natural gas; biogas; GWP; PE; hydrogen; nitrogen; technologies.;

    Abstract : The increasing global population has placed significant pressure on meeting food demands, leading to the widespread use of fertilizers to enhance crop yields. Urea, being the most used fertilizer globally, has contributed to improved agricultural productivity. READ MORE

  6. 10. Reuse and recycling of concrete : Economic barriers and possible opportunities for future profitability

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Julia Knutsson; [2023]
    Keywords : Reuse; Recycling; Circular economy; Construction industry; Building material; Concrete industry;

    Abstract : Today, the world's natural ecosystems are threatened by increased extraction of raw materials andgreenhouse gas emissions to the atmosphere. One of the drivers of this problem is the impact fromindustries through their production. A possible strategy to reduce pressure on natural ecosystems is toincrease the use of industrial ecosystems.
