Processing of unconventional sources - wood waste returns the necessity to explore more profound the domain of low bark charge into kraft cooking process and its consecutive influence on quality of manufactured pulps by maximal manufacturing capacity utilization. This work shows the results of chemical analysis of employed wood and bark of spruce and beech. Negative influence of low bark charge in chips (0 to 8 %) was proved on kraft cooking process- on the yield, on the undercooks content and on choosen qualitative parameters of unbleached pulps - Kappa number, lignin, alpha-cellulose, dirt count and brightness.
