1. 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)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

2. Salvaging Death Worlds : Drivers and Barriers to the Adoption of Biogas and Biofertilizer Production Systems on Gotland
University essay from Uppsala universitet/Institutionen för samhällsbyggnad och industriell teknikAbstract : Utilizing an interdisciplinary, multi-level perspective analysis this thesis reviews niche- regime-landscape interactions (analogous to the clusters of actors working at the local level of Gotland representing niche; the regime being national governance goals; and the landscape incorporating global level affairs and institutions such as the European Union (EU)) and their (mis)alignments within the biogas/biofertilizer production system of Gotland, Sweden, a small-island case study for energy-food-transportation transition and sustainable destination development. The study analyzes the heterarchical and polycentric development of biogas on Gotland—a socio-technical niche, nested within a larger energy regime and global landscape for transition—developing an understanding of (mis)alignments of pressures interacting on, at, and between the niche-regime- landscape as they combine with the peculiar competencies, as Loorbach describes, “creative minds, strategists, and visionaries” of a cluster of actors working in the food- energy-transport nexus on the island (2010, p.

3. A comparative Life Cycle Assessment (LCA) study of centralized and decentralized wastewater heat recovery in Stockholm, Sweden
University essay from KTH/EnergiteknikAbstract : The cities bear a large role in the climate crisis. However, this also means that they have a big potential in the transition towards sustainable communities and a sustainable world. Up to 90 % of energy use within the urban water cycle is allocated to hot water heating for end users. READ MORE

4. 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.

5. Opportunities for increased nutrient recovery at centralised wastewater treatment plants through urine separation
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : Municipal wastewater contains a significant amount of nutrients such as phosphorus (P) and nitrogen (N). Therefore have the interest of recovering these nutrients at wastewater treatment plants (WWTP) increased. Nutrient recovery would generate revenue for the WWTP, as it is possible to sell the products as fertiliser. READ MORE
