  5. 4. Energy and nutrient recovery from dairy manure : Process design and economic performance of a farm based system

    University essay from Linköpings universitet/Industriell miljöteknik; Linköpings universitet/Tekniska högskolan

    Author : Filip Celander; Johan Haglund; [2014]
    Keywords : Manure; cattle; fertiliser; nutrient recovery; renewable energy; manure separation; struvite; Stallgödsel; gödsel; gödselseparering; växtnäring; förnyelsebar energi; struvit;

    Abstract : This thesis assessed the technical and economic premises for installing systems that process manure in order to recover nutrients and inherent energy. The main purpose of recovering nutrients was to extract phosphorus from the manure, so as to be able to distribute more of the manure on the farm without exceeding the phosphorus regulation.
