Abstract: To alleviate the current chip supply shortage in the province of British Columbia, and to make use of mountain pine-beetle- killed wood that is unsuitable for lumber production, whole log chipping of heavily checked, grey-stage beetle-killed wood to provide an additional chip supply for the pulp and paper industry is explored. Chipping productivity, hog fuel and fibre recovery, and chip quality of a satellite chipping yard are evaluated. Whole log chipping of heavily checked grey-stage trees resulted in high ratios of pins and fines, but otherwise good quality chips. Kraft and TMP pulps made from such whole log chips did not show any quality concerns. Heavily-checked, grey-stage mountain pine beetle-killed wood thus provides a suitable source of raw material for whole log chipping operations and the resulting chips can be used to supplement the chip feed of kraft and TMP mills.
