1. 21. Är det transporteffektiva samhället i antågande?

   University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

   Author : Thomas Norman; [2023]
   Keywords : Transporteffektivt samhälle; Implementering; Hållbar mobilitet; Hållbar stadsutveckling; trafikstrategier; styrmedel;

   Abstract : Samhället behöver begränsa klimatpåverkan till hållbara nivåer både globalt och nationellt. Transportsektorns klimatpåverkan är stor och vägtrafikens utsläpp dominerar, men kan minskas genom mer energieffektiva fordon, förnybar energi och ett transporteffektivt samhälle och framförallt genom en kombination av dessa.

3. 22. Do OTC warming effects on ecosystem processes depend on moss species identity, precipitation, and moss removal?

   University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Author : Alexina Brännlund; [2023]
   Keywords : Experimental warming; Subarctic tundra mosses; Productivity; Ecosystem respiration; Decomposition;

   Abstract : Long-term warming experiments in arctic tundra have resulted in reduced moss cover and increased vascular plant cover. As mosses have a major impact on microclimatic conditions, changes in community composition can potentially alter direct and indirect drivers of productivity and decomposition, which are low in arctic ecosystems.

4. 23. IMPLEMENTATION OF NITROGEN RECOVERY AT WASTEWATER TREATMENT PLANTS TO COMPLEMENT ARTIFICIAL FERTILISER PRODUCTION : An investigation of the nitrogen recovery potential, energy consumption and environmental impacts at Kungsängens wastewater treatment plant in Västerås, Sweden

   University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

   Author : Cassandra Kestran; Olivia Larsson; [2023]
   Keywords : Ammonia stripping; Eutrophication; Fertiliser production; Gas permeable membrane; Haber-Bosch; Nitrogen management; Nitrogen recovery technologies; Nitrogen removal; Reject water;

   Abstract : As Kungsängens wastewater treatment plant is considering a move, it opens up a possibility to implement nitrogen recovery technologies that comply with current and future legislative requirements. Nitrogen recovery offers simultaneous treatment of wastewater and collection of concentrated ammonia products for fertiliser production. READ MORE

5. 24. Possibility for Positive Energy Retrofit in Borlänge

   University essay from Högskolan Dalarna/Institutionen för information och teknik

   Author : Daniel Nay Myo Tun; Abideen Olaide Bakare; [2023]
   Keywords : ;

   Abstract : The built environment accounts for 40% of annual carbon dioxide (C02) emissions. Among the total emissions, building operations generate approximately 27% annually. Other than this, building materials, infrastructural materials, and construction (embodied carbon) contribute to an additional 13% annually [1]. READ MORE

6. 25. 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.
