  1. 1. Biogas Potential in the North of Sweden : Inventory and Techno-Economic Assessment of Substrates for an Increased Biogas Production in Norrbotten

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Alma Fahlén Hammar; [2023]
    Keywords : Biogas; anaerobic digestion; AD; Norrland; bioenergy; fossil-free; chemical engineering; Chemistry; Technology and Engineering;

    Abstract : Great investments are planned in the north of Sweden the coming years, not the least in the county of Norrbotten where the projects collectively are referred to as the green transition due to the focus on fossil-free techniques. But to be able to secure a sustainable energy supply and reach the goal set by the member states of the European Union of a carbon dioxide neutral union in 2050 the production of alternative energy sources needs to intensify.

  3. 2. Energy recovery through anaerobic co-digestion of food waste and wastewater treatment sludge : A proposition of a water treatment and biogas plant for a floating island in Stockholm.

    University essay from Linnéuniversitetet/Institutionen för byggd miljö och energiteknik (BET)

    Author : Rodrigo Bahena; [2022]
    Keywords : ;

    Abstract : The urge for more sustainable living motivated the Stockholm Tiny House Expo. The project aims to build a floating, sustainable, man-made island for living and working outside of Stockholm. This paper proposes a waste management method with possible energy recovery for the island. READ MORE

  4. 3. Anaerobic Co-digestion of steam pretreated wheat straw and sewage sludge

    University essay from Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Author : Virginia Tosi; [2021]
    Keywords : Anaerobic co-digestion; wheat straw pretreatment; nutrients availability; OLR; VFA acumulation; Biotechnology; Technology and Engineering;

    Abstract : Anaerobic digestion (AD) of wastes and residues is a widely applied and explored process. However, when the process is not optimized, inadequate concentrations of nutrients and inhibitory compounds are common and can lead to low maximum organic loading rates and increased risk of process problems, low organic dry solids degradation rate and reduced methane yields.

    Keywords : sludge dewatering; sewage sludge; laboratory scale sludge treatment; dewatering sludge; dewatering sewage sludge; CST; capillary suction time test; centrifuge; lab-centrifuge; rheology; polymers conditioning; sludge conditioning; centrifuge on lab scale; evaluation of lab experiments; CST evaluation; mechanical de-watering evaluation; sludge dewatering at lab; lab scale dewatering process; sludge dewatering methods at lab; Chemical engineering; Lab centrifuge; Capillary Suction Time CST ; Mechanical sludge dewatering evaluation; Polymers conditioning of sludge; sewage sludge dewatering; methods for sludge dewatering at lab; water engineering; environmental engineering; vattenförsörjningsteknik; avloppsteknik; Chemistry;

    Abstract : After the sewage wastewater is collected from different households and directed to the treatment plants, it goes through several processes, which are physical, chemical and biological. The different processes remove the contaminant, and produce a semi-solid material named sludge. Sludge has a huge amount of liquid. READ MORE
