    Detta är en avhandling från Stockholm : KTH

    Författare :Victor Cucarella Cabañas; KTH.; [2009]
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Compact filter; Filtra P; Phosphorus recycling; Polonite; Soil amendment; Sorption isotherms; FORESTRY; AGRICULTURAL SCIENCES and LANDSCAPE PLANNING Soil science; SKOGS- och JORDBRUKSVETENSKAP samt LANDSKAPSPLANERING Markvetenskap; NATURAL SCIENCES Chemistry Inorganic chemistry Solution chemistry; NATURVETENSKAP Kemi Oorganisk kemi Lösningskemi; FORESTRY; AGRICULTURAL SCIENCES and LANDSCAPE PLANNING Area technology Agricultural engineering; SKOGS- och JORDBRUKSVETENSKAP samt LANDSKAPSPLANERING Areell teknik Jordbruksteknik; TECHNOLOGY Civil engineering and architecture Water engineering; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur Vattenteknik; NATURAL SCIENCES Chemistry Environmental chemistry; NATURVETENSKAP Kemi Miljökemi;

    Sammanfattning : This thesis studied the viability of recycling filter substrates as soil amendments after being used in on-site systems for phosphorus (P) removal from wastewater. Focus was put on the materials Filtra P and Polonite, which are commercial products used in compact filters in Sweden. LÄS MER

  3. 3. Impact of horse-keeping on phosphorus (P) concentrations in soil and water

    Detta är en avhandling från Stockholm : KTH

    Författare :Masud Parvage; Sveriges lantbruksuniversitet.; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Agricultural sources contribute significantly to the high phosphorus (P) loads in water, causing eutrophication in many of Europe’s water bodies. Consequently, priority has been given to reducing P leakage from sources, including soils used for animal farming. LÄS MER

  4. 4. Bioaugmentation for reduction of diffuse pesticide contamination

    Detta är en avhandling från Stockholm : KTH

    Författare :Karin Önneby; Sveriges lantbruksuniversitet.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Pesticides and their residues frequently contaminate surface waters and groundwater so consequently there is a great need to identify methods and practices that reduce such contamination. This thesis examined the potential of a 'bioprophylactic' concept based on the hypothesis that diffuse contamination after application in the field can be significantly reduced if pesticides are degraded as rapidly as possible after the intended effect has been achieved.

  5. 5. On Sustainability of Biomass for Energy and the Governance Thereof

    Detta är en avhandling från Chalmers University of Technology

    Författare :Oskar Englund; Chalmers tekniska högskola.; Chalmers University of Technology.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Bioenergy; biomass production; sustainability; land use; governance; certification; environmental legislation; biodiversity; ecosystem services; biomass resources; GIS; spatial modelling;

    Sammanfattning : Due to concerns about climate change, energy security, and resource scarcity, non- renewable resources are increasingly being displaced by biomass. As with most human activities, the production of biobased products can be associated with negative impacts. Primarily, this relates to the biomass supply systems, i.e. LÄS MER
