1. 1. Biochar as a carbon dioxide removal solution : An assessment of carbon stability and carbon dioxide removal potential in Sweden

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Alessandro Corbo; [2020]
   Keywords : Climate change mitigation; biomass; pyrolysis; soil;

   Abstract : Biochar is increasingly gaining momentum in the context of climate change mitigation and its production in Sweden could potentially become a large-scale system. Carbon stability in biochar is a crucial factor to assess its the carbon sequestration potential. READ MORE

3. 2. Limiting microplastic pollution from municipal wastewater treatment : A circular economic approach

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Jordy van Osch; [2020]
   Keywords : Microplastics; circular economy; wastewater treatment plant; resource recovery; Multi-criteria analysis;

   Abstract : The increasing amount of microplastics found in the environment have underscored the urgency to identify, develop and deploy scenarios in which municipal wastewater treatment plants (MWWTPs) limit the release of urban microplastics into the environment. Simultaneously, the global trend towards a circular economy has defined the conditions for these scenarios in relation to the water-energy- nutrient nexus. READ MORE

4. 3. Pharmaceuticals leaching from biosolids amended soils

   University essay from SLU/Dept. of Aquatic Sciences and Assessment

   Author : Anastasia von Hellens; [2015]
   Keywords : biosolids; pharmaceuticals; leaching; soil texture; correlation analysis; physiochemical properties;

   Abstract : Biosolids are currently applied on arable land in order to recirculate nutrients from urban areas. Biosolids have been reported to contain organic con-taminants such as pharmaceuticals; thereby the impact of spreading of bio-solids on the environment has to be investigated. READ MORE

5. 4. Optimised ammonia sanitation of sewage sludge

   University essay from SLU/Dept. of Energy and Technology

   Author : Franziska Häfner; [2014]
   Keywords : ammonia; urea; sanitisation; compost; sewage; sludge; Enterococcus faecalis; Escherichia coli; Salmonella Typhimurium; Ascaris suum; somatic coliphages;

   Abstract : The usage of sewage sludge as an organic fertiliser offers a way to recycle nutrients and organic matter for a sustainable agriculture. Sewage sludge is rich in plant nutrient like nitrogen, phosphorus, potassium and micronutrients. READ MORE

6. 5. Descriptive Assessment and Amendment of the SimpleTreat Model - Modelling of Organic Chemicals in Sludge for Soil Applications

   University essay from Lunds universitet/Industriell elektroteknik och automation

   Author : Belinda Chieng; [2012]
   Keywords : SimpleTreat; organic compounds; REVAQ; soil amendment; methodology; WWTP; fugacity and steady-state model; Technology and Engineering;

   Abstract : Large quantities and numbers of organic compounds (OCs) from industries and domestic sources enter the wastewater treatment plants (WWTPs) everyday, which is an ever-increasing issue in modern society. In WWTPs, the pollutants are either degraded or emitted to the air, the effluent (water) or the sludge (biosolids). READ MORE
