  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. Långsiktig torvnedbrytning för olika vegetationstyper på dikad skogsmark

    University essay from SLU/School for Forest Management

    Author : Carl Carlsson; Sofie Jönsson; [2023]
    Keywords : växthusgaser; torvmark; dikning;

    Abstract : Skogsklädda torvmarker i Sverige dikades i stor utsträckning mellan 1930- och 1980-talen i syfte att höja virkesproduktionen. Till följd av klimatproblemet har intresset för dikade torvmarkers bidrag till växthusgasutsläppen ökat under de senaste decennierna. READ MORE

  4. 3. Quality of Spent Mushroom Compost Amended with Organic Material- Effect on Nutrient Content and Plant Growth

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Rasha Kamel; [2023]
    Keywords : Apple Waste; Wood Chips; Microbial Content; pH; Pseudomonas; General Bacterial Flora; General Fungal Flora; Electrical Conductivity; Nutrient Content; Bulk Density; Porosity; Water Holding Capacity;

    Abstract : Peat, as a non-renewable growing media, poses environmental concerns due to extraction and decomposition processes, leading to increased greenhouse gas emissions. Alternatives growing media with potential to replace or reduce the use of peat are of great need. READ MORE

  5. 4. The potential nitrous oxide emissions in a permanent grassland chronosequence

    University essay from SLU/Dept. of Forest Mycology and Plant Pathology

    Author : Sandra Lillsjö Kronblad; [2023]
    Keywords : nitrous oxide emission; permanent grasslands; denitrification; nitrous; reen house gas; agriculture;

    Abstract : As a part of a larger project (Belowground biodiversity of grasslands – conservation needs and potential to promote sustainable agriculture), this study aims to investigate potential nitrous oxide (N2O) emissions and microbial gene abundances needed for the production (nirS and nirK) and reduction (nosZI and nosZII) of nitrous oxide in soil of permanent grasslands of various age. Thegrasslands have at different times been converted to permanent grasslands and are of interest because of the possibility to shed more light about the passage of time’s affects on the soil microbialcommunities and their activity.

  6. 5. Biokolets påverkan på dagvattenkvaliteten i regnbäddar

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Maja Hammarstedt; Wilma Insulander; [2023]
    Keywords : Biokol; dagvatten; regnbädd; vattenkvalitet; föroreningar; StormTac; dagvattenrening; näringsämnen; växtbädd; urban miljö;

    Abstract : Klimatförändringar och en större andel hårdgjorda ytor i städerna bidrar till en ökning av dagvatten som måste ledas bort. För att förhindra överbelastade VA-ledningar behöver dagvattnet fördröjas inom avrinningsområdet. En stor del av dagvattnet innehåller föroreningar från bland annat vägar, parker och industriområden.
