Abstract
The use of recycled fibres during paper production mostly leads to microbial contamination of the papers. The higher microbial load of papers made from secondary fibres compared with those from virgin fibres is of disadvantage for specific applications of paper, e.g. in food packaging or in the use as hygienic papers (paper napkins, paper towels etc.). In order to reduce the microbial load of papers made from recycled fibres several preventive measures were studied: Evaluation of the recovered paper grade; Storage conditions of recovered paper; Conditions of bleaching and/or hot dispersing during paper production. It was shown that proper handling of recovered paper enables the production of papers from secondary fibres with a low microbial load comparable to products made from virgin fibres.
