  1. 1. Nutrient dynamics in pak choi cultivation fertilized with biogas digestate : effects of non-nutrient digestate elements and amendment with mineral nutrients

    Master-uppsats, SLU/Department of Biosystems and Technology (from 130101)

    Författare :Kristina Weimers; [2020]
    Nyckelord :Biogas digestate; pak choi; Brassica rapa; ssp. chinensis; ‘Joy Choi’; greenhouse; soilless production; peat-based growing media; biostimulants; nitrification; nutrient recovery efficiency; phosphorus; sulphur;

    Sammanfattning : Anaerobic digestion in biogas plants produces renewable energy and a residue which is rich in plant nutrients. This residue is called digestate. Today, these digestates are mostly spread directly onto fields as manure. LÄS MER

  3. 2. Organic flows : Swedish farmers' perspectives on the use of anaerobic digestates as a fertilizer : a behavioral approach on nine case-studies in Scania, Southern Sweden

    Master-uppsats, SLU/Dept. of People and Society

    Författare :Maaike Happel; [2016]
    Nyckelord :anaerobic digestates; theory of planned behavior; ecosystem-services; circular economy; zero waste; agroecology;

    Sammanfattning : This thesis aims to understand farmers’ decision-making behavior from a socio-psychological perspective. In view of a growing need to rethink and reshape our current production systems towards their original circular nature, processing green waste into biogas offers a realistic potential and is already a growing sector in Sweden.

  5. 4. Hur säkrar man en framtida framgångsrik avsättning av biogödsel? Ansvar från bord till jord

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Inga Gunnarsson; [2012]
    Nyckelord :Digestate; Biogas; Earth and Environmental Sciences;

    Sammanfattning : Increased greenhouse gas emissions generated by human activity are causing climate change. This has created a need for greater production of renewable energy. Biogas produced from organic waste such as manure and municipal solid organic waste could contribute to meeting the increased demand for renewables. LÄS MER
