FIELD: textile, paper.
SUBSTANCE: method represents reduction of transition metals content in a milled mass to a level unfavorable for sporulation. Preferably, bacterial cells present in the milling system of cardboard or paper machine in fact are not destroyed in the process of technological operations used to reduce the content of transition metals. The method also refers to obtaining packing board or packing paper characterised with a low content of bacterial spores, when to obtain packing board or packing paper a milled mass is used in which the content of transition metals is reduced to a level unfavorable for sporulation.
EFFECT: reduction of bacterial spores in the milling system of a cardboard machine.
