  1. 1. Pyrolysis of Municipal Sewage Sludge to get a phosphorus rich char residue for soil improvement

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Shahin Shamim; [2023]
    Nyckelord :Sewage Sludge-Phosphorus-Pyrolysis- Heavy metals; Cadmium; Lead; Nickle; Copper; Chromium; Zinc; Biochar; Heating value; Fertilizer- Thermal conversion;

    Sammanfattning : Sewage sludge is a byproduct of wastewater treatment plants. It is a kind of waste. however, it contains several valuable nutrients like phosphorous and nitrogen that are used to rich the soil as a fertilizer compound. LÄS MER

  3. 2. Chemical Kinetic Modeling of the Combustion of NH3/H2 and NH3/syngas Fuel Mixtures Using a Large Amount of Experimental Data

    Master-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Andras Szanthoffer; [2022]
    Nyckelord :Ammonia combustion; Detailed chemical kinetic mechanisms; Quantitative mechanism comparison; Local sensitivity analysis; Chemical Physics; Chemistry;

    Sammanfattning : Nowadays, due to the global climate change, it is extremely important to find alternative fuels to reduce the utilization of fossil fuels and the emission of air pollutants such as carbon dioxide (CO2), hydrocarbon pollutants, and soot. Ammonia (NH3) is a promising carbon free fuel candidate that can store and transport renewable hydrogen (H2) energy. LÄS MER

  4. 3. Wild bee species and farming practices in horticultural farms in Madrid : finding paths towards agroecological transitions

    Master-uppsats, SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Författare :Inés Gutiérrez Briceño; [2022]
    Nyckelord :wild bee; pollination; biodiversity; ecosystem services; landscape; mapping; semi-structured interview; agroecology;

    Sammanfattning : Farms and its different management practices have substantial effects on biodiversity, with the consequent impact on the supply of certain ecosystem services such us pollination. Wild bees provide pollination services in small scale horticultural farming, which is key element to determine and improve farm production but also to the maintenance of ecosystem´s diversity.

  5. 4. POLYAROMATIC HYDROCARBONS IN HYDROCHARS : HYDROTHERMAL CARBONIZATION OF SEWAGE SLUDGE

    Master-uppsats, Umeå universitet/Kemiska institutionen

    Författare :Björn Sundqvist; [2021]
    Nyckelord :;

    Sammanfattning : Sewage sludge is an inevitable by-product from waste water treatment plants. Sludgemanagement is a difficult task since sludge has a high moisture content, poordewaterability and generally contain heavy metals, pharmaceutical residues,polyfluorinated alkyl substances (PFAS) and organic pollutants.
