    Nyckelord :Thermo mechanical pulping TMP ; Energy reduction; Enzyme; Pilot scale refining; Reducing sugar assay;

    Sammanfattning : Thermomechanical pulping (TMP) is a highly energy intensive process where most of the energy is used in therefining of chips to fibres. Various ways of reducing the energy consumption have earlier been studied, for examplechange of refiner pattern, addition of various chemicals, and also some biochemical implementation in the form of fungus and enzymes.
