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)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.

2. Improved prediction of biogas production at Uddebo wastewater treatment plant : Substrate modelling in SIMCA
University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserAbstract : Anaerobic digestion is a complex process, dependent on multiple factors, which can be made more stable and efficient with the help of process models. A more stable process could reduce biogas torching, which increases the amount of renewable energy available for heat- and electricity production and vehicle fuel. READ MORE

3. Anaerobic Co-digestion of steam pretreated wheat straw and sewage sludge
University essay from Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)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.

4. Comparison of mesophilic and thermophilic anaerobic sludge digestion at Hammarby Sjöstadsverk MBR pilot plant for wastewater treatment
University essay from SLU/Department of Molecular SciencesAbstract : Anaerobic digestion is a commonly used method for stabilisation of sewage sludge and production of biogas at municipal wastewater treatment plants (WWTPs). The hydraulic retention time for sludge in the digestion reactors is about 16 days at Henriksdal WWTP in Stockholm. READ MORE

5. Feasibility Study for Production of Biogas from Wastewater and Sewage Sludge : Development of a Sustainability Assessment Framework and its Application
University essay from KTH/EnergiteknikAbstract : Clean water and renewable energy are essential requirements to build resilience towards the adverse effects of climate change and global warming. Advanced wastewater treatment options may provide a unique opportunity to recover various useful resources such as energy (biogas), fertilizers, minerals, and metals embedded in the wastewater stream.
