  1. 11. The Influence of Pigment Additives on the Barrier Properties of Dispersion Coatings

    University essay from KTH/Fiber- och polymerteknologi

    Author : Malin Eriksson; [2022]
    Keywords : dispersion coating; paper products; pigment; sustainable development; circular economy; Dispersionsbarriär; pappersprodukter; pigment; hållbar utveckling; cirkulär ekonomi;

    Abstract : Att minska plastavfall och uppmuntra återvinning har fått hög prioritet i många affärsverksamheter och olika typer av regleringar implementeras för att minska den negativa påverkan av plastanvändningen. Papper och kartong består i huvudsak av cellulosa som har många egenskaper som är essentiella för en hållbar ekonomi (t.ex. READ MORE

  2. 12. How the Choice of Primary Treatment Affects the Biogas Potential of Primary Sludge

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Fanny Blom; [2022]
    Keywords : wastewater treatment; primary treatment; biogas potential; primary settling treatment; rotating belt filter; chemically enhanced primary treatment; environmental engineering; water resources engineering; Technology and Engineering;

    Abstract : The global heating has resulted in rising temperatures and more extreme weather conditions around the world. In combination with increasing energy demands, this has led to an increasing demand of renewable energy. One option is utilizing the wastewater to produce biogas. There-fore, wastewater can be seen as a resource rather than waste. READ MORE

  3. 13. Life Cycle Perspective on School Buildings’ Energy Retrofitting
