  1. 26. COD fractionation of wastewater on cruise liners before and after advanced treatment

    Kandidat-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Karin Ekström; Jenni Borg; [2015]
    Nyckelord :Chemical oxygen demand; COD; biodegradability; wastewater; permeate; water treatment; cruise liners; analytical chemistry; ozonation; nanofiltration; physiochemical method;

    Sammanfattning : The purpose of this Bachelor thesis was to establish a method for determining the chemical oxygen demand (COD) fractionation in wastewater from cruise liners. COD fractions of interest were soluble biodegradable (SS), particulate biodegradable (XS), soluble unbiodegradable (SI) and particulate unbiodegradable (XI). LÄS MER

  3. 27. Är det möjligt att tillverka antibakteriellt papper med hjälp av kitosan fibrer?

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Kristina Junel; [2015]
    Nyckelord :Antibacterial; chitosan; fibers; polylactide; spinning;

    Sammanfattning : Fibers are classified into two groups; natural fibers and man-made fibers (MMF). There are three kinds of MMF: those made by transformation of natural polymers, those made from synthetic polymers and those made from inorganic material. Chitosan is classified as a biobased polymer and can be spun into man-made fibers. LÄS MER

  4. 28. Systematic Assessment of Straw as Potential Biogas Substrate in Co-digestion with Manure

    Master-uppsats, Linköpings universitet/Industriell miljöteknik; Linköpings universitet/Tekniska högskolan

    Författare :Sutina Duong; [2014]
    Nyckelord :Biogas; substrate; straw; systematic assessment; renewable energy; biofertilizer; anaerobic digestion; Biogas; biogassubstrat; halm; systematisk utvärdering; förnybar energi; biogödsel; rötning;

    Sammanfattning : This work was carried out at Biogas Research Center (BRC) and the company Biogas in Vadstena. The aim was to systematically evaluate new substrates for biogas production. In particular, this case investigated the potential of straw in co-digestion with manure and slurry from pig, chicken and dairy. LÄS MER

  5. 29. Evaluation of the sustainability of hemp fiber reinforced wheat gluten plastics

    Master-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Faraz Muneer; [2012]
    Nyckelord :wheat gluten; hemp fiber; sustainability; plastics; biodegradability;

    Sammanfattning : Bio-based plastics and composites are getting attention as an alternative to unsustainable petro-chemical based plastics. Hemp fiber reinforced wheat gluten (WG) composites can be an alternative to petro-chemical based plastics in many applications, because of their interesting tensile properties and environmental friendliness.

  7. 30. Anaerobic digestion of food and market waste; Waste characterization, Bio methane potential and Bio reactor design : a Case study in Sri Lanka

    Master-uppsats, Högskolan i Gävle/Avdelningen för bygg- energi- och miljöteknik

    Författare :Malkanthi Thenabadu; [2010]
    Nyckelord :Anaerobic Digestion; Market waste;

    Sammanfattning : Anaerobic digestion is the process that generates the biogas. This process can be used successfully to treat municipal organic solid wastes and kitchen waste to produce valuable end products, such as methane gas and fertilizer. LÄS MER
