    University essay from Linköpings universitet/Energisystem

    Author : Bogdan Radu Racsi; [2023]
    Keywords : high pressure die casting; HPDC; energy efficiency; cast house remelting; internal aluminium scrap; melting furnace; melting and holding furnace; drivers; barriers;

    Abstract : The aluminium industry is anticipated to witness a surge in demand, with projectionsof a two to three-fold increase by 2050. Meeting environmental objectives andaddressing the growing emphasis on sustainability from both the industry andconsumers seeking eco-friendly products present significant challenges. READ MORE

  3. 2. The effect of recycling and processing routes on recrystallization in a secondary 3xxx aluminium alloy

    University essay from Jönköping University/JTH, Material och tillverkning

    Author : Anton Rolseth; [2023]
    Keywords : Aluminium alloys; sheet metal forming; grain boundary segregation; recrystallization; Zener pinning; casting; rolling;

    Abstract : Aluminium alloys have the possibility to be infinitely recycled. By only generating 5% of the emissions compared to primary aluminium, great CO2 savings can be made. One of the issues in manufacturing components entirely from post-consumer scrap is the presence of trace elements and impurities. Such elements can be Fe, Cu, Cr, P and Pb. READ MORE

  4. 3. Screening pyrolysis bio-oil as binder for carbon anode in aluminium production

    University essay from KTH/Fiber- och polymerteknologi

    Author : Yazhe Wang; [2023]
    Keywords : Biomass; Bio-oil; Bio-pitch; Carbon Anode; Aluminum production; Biomassa; Bioolja; Biobeck; Kolanod; Aluminium Produktion;

    Abstract : Den högkvalitativa stenkolstjäran, som används som anodbindemedel inom aluminiumindustrin, innebär utmaningar när det gäller att möta kraven på kolanod. Dess produktion är beroende av ohållbara fossila bränslen, vilket bidrar till ökade koldioxidutsläpp. READ MORE

  5. 4. Mercury accumulation in lake sediments on different time scales – the influence of algal primary production

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

    Author : Anne Rebotzke; [2023]
    Keywords : mercury; lake sediment; primary productivity; algal scavenging; biogenic silica; diatom proxy; chlorophyll-a; organic matter;

    Abstract : The aim of this work is to test the proposed approach of algal scavenging as a driver of sediment mercury (Hg) on different time scales and to gain a better understanding of the mechanisms of Hg accumulation in lake sediments. A 3000-year sediment record from Nylandssjön in northern Sweden was analysed for this purpose, as well as a 20-year sediment record from the seasonal sediment traps of this lake. READ MORE

  6. 5. Recycling end-of-life silicon PV panel with molten salt bath

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

    Author : Liying Yu; [2023]
    Keywords : ;

    Abstract : Solar energy is recognized as a clean way to produce electricity. Solar PV's installed capacity is increasing in recent years. However, a PV panel has a 25-year lifespan on average. In actuality, 95% of the mass of PV components can be recycled. READ MORE
