  1. 1. Enhancement of hydrolysis from co-fermentation of food waste and primary sludge

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Johnny Hagelin; [2021]
    Nyckelord :Environmental engineering; Bioaugmentation; Fermentation; Hydrolysis; Resource recovery;

    Sammanfattning : Research about resource recovery from complex waste streams is getting an increased scientific attention since valuable resources can be produced by sustainable biological means. In anaerobic degradation processes, resources such as volatile fatty acids (VFAs) and biogas are highly coveted. LÄS MER

  3. 2. Volatile fatty acid production and application as external carbon source for denitrification

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Cora Michelle Döhler; [2020]
    Nyckelord :VFAs; co-fermentation; primary sludge; food waste; denitrification; external carbon source; MBBR;

    Sammanfattning : By rethinking wastewater treatment plants (WWTPs) as resource recovery facilities, it is possible to de- velop the next generation of WWTPs. Moreover, it allows to accomplish environmental goals, such as reducing the CO2 footprint, and comply with increasing effluent standards regarding the concentration of nitrogen in a more sustainable way.

  4. 3. Volatile fatty acid production from co-fermentation of primary sludge and food waste without pH control

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Binyam Bedaso; [2019]
    Nyckelord :Volatile fatty acid; Co-fermentation; Primary sludge; Food waste;

    Sammanfattning : The production of volatile fatty acids (VFAs) from waste stream is gaining high attention because of their high market value and wide range of applications. In this study, the production of VFA from co-fermentation of primary sludge from wastewater treatment plant and food waste without pH control was evaluated using a pilot-scale reactor in a semi-continuous mode of operation.

  5. 4. From Waste to Bioethanol - A Feasibility Study on Animal Bedding

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Ajsa Hodzic; Desirée Karlsson; [2017]
    Nyckelord :Bioethanol; Biofuels; Second generation bioethanol; Animal Bedding; Fermentation; SSF; SSCF; Lignocellulose; Chemical Engineering; Kemiteknik; Bioteknik; Technology and Engineering;

    Sammanfattning : For the year 2020, the European Union has set common goals to aim for regarding the environment. One of them being to reduce the green house gas (GHG) emissions by 20 percent. The world population is increasing, consequently increasing the demand for energy and food. LÄS MER

  7. 5. Impact of Using Macroalgae from the Baltic Sea in Biogas Production : A Review with Special Emphasis on Heavy Metals

    Master-uppsats, Linnéuniversitetet/Institutionen för naturvetenskap, NV

    Författare :Kristofer Bergström; [2012]
    Nyckelord :biogas; macroalgae; heavymetals; Trelleborg;

    Sammanfattning : A consequence of eutrophication in the Baltic Sea is growth of algae that accumulates in the coastal areas and beaches. Dense algal mats may cause anoxia or hypoxia and greatly reduce the recreational value of the area. Algae also functions as hyper accumulators of heavy metals and their metal levels may become toxic to higher trophic levels. LÄS MER
