Résumé
Forest products companies in the ILMA region covering four areas, Cranbrook, Kootenay, Vavenby and Okanagan, were surveyed for their current mill residue utilization. Although the Cranbrook area showed the lowest utilization of bark residues (0 %), it showed the highest utilization for whitewood, sawdust and shavings (98%). Overall, the Okanagan area generated the largest amount of bark and whitewood residues and showed the highest utilization for these residues (69% utilization for bark and 86% for whitewood). The Kootenay area generated the second highest amount of bark and whitewood residues and showed the second highest utilization for these residues (67% utilization for bark and 76% utilization for whitewood). The amounts of bark, sawdust and shavings, slabs, trim ends and yard debris generated and utilized for the above four areas are presented in this report. In 1996, the utilization of bark and sawdust / shavings residues in the ILMA region as a whole was 49.8% and 83.8% respectively compared to 28% and 45% respectively in 1989 showing a substantial increase in utilization. The primary use for sawdust and shavings was found to be pulp furnish followed by particleboard/fibreboard furnish, internal process heat, and agricultural/bedding material. The primary use for the bark residues was for energy generation, either through cogeneration or for internal process heat. There are few value-added product opportunities for bark in comparison to sawdust and shavings. However, a new value-added hog fuel/bark board recently patented by Forintek may have potential to utilize some quantities of bark residues, providing a number of technical, environmental and economic questions can be satisfactorily addressed. Another new product, BiolimeTM, also shows some potential for utilizing large quantities of bark residues.
