DEINKING TONER-PRINTED PAPER BY SELECTIVE AGGLOMERATION

The use of agglomeration to deink toner-printed paper remains a promis ing technique whose potential is under utilized because of a lack of f undamental study of the process. Therefore, this work examines the imp ortance of cationic starch in paper, agglomerating oil composition and temperature for successful deinking. The Findings combine to form an overall view of the competition between aggregate buildup and breakdow n and provide background for the rational design nf future agglomerati on deinking operations.
