  1. 1. Towards Water Resource Recovery Facilities : Environmentally Extended Techno-Economic Assessment of Emerging Sewage Sludge Management Technologies in Sweden

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Harry Tibbetts; [2023]
    Keywords : Circular Economy; Waste Valorisation; Systems Analysis; LCA; MFA; EFA; TEA; Hydrothermal Carbonisation; Cirkulär ekonomi; Waste Valorisation; Systems Analysis; LCA; MFA; EFA; TEA; Hydrotermal Carbonization;

    Abstract : Municipal sewage sludge (MSS) management varies widely between countries and legislative regimes. Within the European directive for sewage treatment France applies over half of MSS to arable land, while The Netherlands has banned the practice (Kelessidis et al, 2012). READ MORE

  3. 2. Swedish Nitrogen Flows : A national budget of anthropogenically induced reactive nitrogen

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Vincent Lernbecher; [2021]
    Keywords : ;

    Abstract : Nitrogen is a fundamental element in all forms of life and a crucial component of our agricultural productivity and global food security. However, excess nitrogen caused by human activity poses a serious threat to the environment and human health. READ MORE

  4. 3. Influence of land cover changes on organic carbon and organic nitrogen concentrations in Swedish rivers

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Julia Iwan; [2021]
    Keywords : Total Organic Carbon TOC ; Total Organic Nitrogen TON ; Land Cover Change; Sweden; WaterBase; Earth and Environmental Sciences;

    Abstract : There is increasing pressure on freshwater systems due to excessive nutrient loading by anthropogenic sources. In Sweden, freshwaters have become browner due to increasing exports of organic matter from soils into streams, rivers, and lakes. READ MORE

  5. 4. Decreasing organic nitrogen concentrations in European water bodies - links to organic carbon trends and land cover

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Alexis Cazorla; [2020]
    Keywords : geography; GIS; physical geography; organic nitrogen; organic carbon; land cover; eutrophication; Europe; Earth and Environmental Sciences;

    Abstract : European rivers experience increasing concentrations of total organic carbon (TOC) from terrestrial sources due to factors involving changes in land use, climate and soil acidity. However, low interest is given to the evolution of total organic nitrogen (TON) concentrations in surface waters, the links with TOC concentrations and the influence of the surrounding land cover on nutrient inputs.

  6. 5. Nitrogen mineralization in a sludge-amended sandy clay loam in South Africa

    University essay from SLU/Dept. of Soil Sciences

    Author : Anna-Karin Mellin; [2005]
    Keywords : sewage sludge; nitrogen mineralisation; incubation; South Africa; soil; decomposition;

    Abstract : Sewage sludge is a solid, semi-solid or liquid byproduct produced by waste water treatment plants. It contains both compounds of agricultural value (e.g. organic material, nitrogen, phosphorous, potassium and to a lesser extent calcium, sulphur and magnesium), and pollutants (e. READ MORE
