Abstract

Deposits from different sections of a newsprint paper mill, using 100% recovered paper, were analyzed
following an analytical procedure based on scaning electron microscopy-electron dispersive X-ray and
consecutive solvent extraction steps with Fourier-transform infrared spectroscopy (FTIR) analyses of the
different fractions. Polyvinyl acetate, polyacrylates, styrene butadiene rubber, and derivatives of fatty acids/
resin acids are the main stickies-related components identified in the deposits. The removal efficiency of
these contaminants along the deinking line was studied by determining the composition of the dichloromethane
extractives in the pulp by FTIR analyses. Although the total stickies content is reduced considerably during
the process, some compounds, which are found in the deposits, are not removed selectively in the process,
indicating their recalcitrant nature. FTIR analyses of unusable materials coming with the raw material (mainly
board and mixed office waste) have demonstrated that these materials are one of the main sources of these
types of recalcitrant stickies.
