  1. 1. Enabling small-scale production of biochar in carbon markets : A multi-actor governance approach

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Linnea Sörman; [2023]
    Keywords : ;

    Abstract : Climate change is increasing the temperature rise, which damages nature and people. Increasing and using carbon dioxide removal (CDR) techniques are crucial to limit global warming to staying under 2 °C and fulfilling the Paris Agreement. There are several different CDR techniques, and biochar is one. READ MORE

  3. 2. Experimental Study of Flow Fields in Moving Bed Biofilm Reactors

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Shea Nee Chew; [2023]
    Keywords : Moving bed biofilm reactors; Biofilm carriers; Mechanical mixing; Mixer configurations; Carrier mixing; Biofilmsreaktorer med rörlig bädd; Biofilmsbärare; Mekanisk blandning; Blandarkonfigurationer; Bärarblandning;

    Abstract : With the rise in global energy prices, as well as energy consumption being the largest source of greenhouse gas emissions, biofilm-based systems utilized for wastewater treatment, such as moving bed biofilm reactors (MBBRs), have grown in popularity for their lower energy consumption compared to conventional activated sludge processes. However, this technology requires large amounts of energy to constantly distribute and suspend its biofilm carrier within the reactor by either aerators or mechanical mixers. READ MORE
