1. 21. Feasibility Study of Available Hydrogen Production Techniques in Sweden using Single-Issue LCA Carbon Footprint

   University essay from KTH/Industriell bioteknologi

   Author : Beatrice Westén; [2022]
   Keywords : Hydrogen; biohydrogen; LCA; Single-Issue LCA; streamlined LCA; Life Cycle Assessment; Carbon Footprint; CF; Environmental System Analysis; Sweden; holistic; future scenarios; Vätgas; biovätgas; LCA; Single-Issue LCA; streamlined LCA; Life Cycle Assessment; Carbon Footprint; CF; Environmental System Analysis; Sverige; holistisk; framtida scenarios;

   Abstract : Sverige har som mål att bli helt fossilfri till år 2045. Energymyndigheten har därför tagit fram ett förslag till Vätgasstrategi för att ställa om vätgasproduktionen till att vara helt fossilfri till 2045. Idag används ca 180 000 ton vätgas, vilket motsvarar ett energiinnehåll på ca 6 TWh. READ MORE

3. 22. Come Fly with Me (Sustainably) : Pathways to Sustainable General Aviation and Private Pilot Training

   University essay from Högskolan i Gävle/Miljövetenskap

   Author : Michael Stiebe; [2022]
   Keywords : General Aviation; Sustainable Aviation; Sustainable Development; Electric Aviation; Noise Pollution; Leaded Fuel; AVGAS 100LL; Tetraethyl Lead Phaseout; Pilot Training; Recreational Aviation; Switzerland;

   Abstract : Whereas commercial aviation is attempting to achieve the reduction of its substantial carbon footprint, general aviation’s (GA) climate change contribution is negligibly small, which is why the sector is facing other sustainability challenges mainly entailing the operation of dated technology and aircraft, increasing regulatory constraints, rising costs, noise emissions, and popular discontent, as well as remaining the last mobility sector in the world to still use leaded fuels. Throughout recent years, there have been remarkable sustainability trends in GA as well as heightened efforts to improve its emissions profile (noise, pollutants, CO2) and environmental reputation, for instance by the increased use of electric aircraft, especially for private pilot training.

4. 23. Råvaruförsörjning av grot : försörjningskedjan vid Södra Skog

   University essay from SLU/Dept. of Forest Economics

   Author : Erik Leijonhufvud; [2022]
   Keywords : primära skogsbränslen; processkartläggning; processbaserad verksamhetsutveckling; skogsbränslen;

   Abstract : Sverige håller på att utvecklas från ett samhälle beroende av fossilbaserade bränslen och produkter till en bioekonomi. Detta innebär att vi måste öka andelen förnyelsebar råvara för att kunna ställa om till en mer biobaserad ekonomi. READ MORE

5. 24. Supply chain collaboration as a facilitator of circular economy for bio-based food packaging

   University essay from Malmö universitet/Institutionen för Urbana Studier (US)

   Author : Gabriela Holesova; Ekaterina Ivashneva; [2021]
   Keywords : supply chain collaboration; bio-based food packaging; circular economy; resource based view; transaction cost economics; circular supply chains;

   Abstract : The amount of food packaging waste is one of the issues associated with increasing global population and corresponding increase in consumption rate of packaged foods. Traditional plastic food packaging derived from fossil fuels imposes a significant environmental threat. READ MORE

6. 25. Transformation of the Aviation industry : Exploring alternative renewal fuel pathways

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