This report discusses options for composting the fines component of residues produced at log sortyards, including composting the fines with a readily available and inexpensive nitrogen source like fish processing waste. Based on the B.C. Agricultural composting Handbook, FERIC calculated the sizing and capacity of a potential logyard fines composting facility. Costs associated with operating a composting site under various equipment ownership and utilization scenarios are presented.
The Forest Engineering Research Institute of Canada (FERIC) undertook a project for Natural Resources Canada (NRCan) to study the transportation of hog fuel from source to consumption site. In particular, FERIC gathered information from companies engaged in the supply, transportation, or use of hog fuel through direct visits or questionnaires. This report presents the types and costs of the various modes of transportation used—specifically truck, rail, and barge—and the advantages and disadvantages of each.
In 1987 and 1988, spacing (precommercial thinning) was undertaken on three one-hectare blocks of interior B.C. lodgepole pine and two one- hectare blocks of Coastal Western Hemlock. Each block received four different treatments during spacing. The survival and development of live limbs on cut stumps are documented. Rep- and post-spacing stand densities, clearing-saw productivity and costs are also reported. This project was funded by the Canada/BC Forest Resources Development Agreement (FRDA) under agreement no. F-52-43-102 and FERIC.
L’Institut canadien de recherches en génie forestier (FERIC) a examiné l’incidence des dommages mécaniques causés aux tiges en longueur, par suite du stockage et de la manutention dans un parc d’usine du nord de l’Alberta. Une projection de la fréquence des bris et de la perte en volume de sciage a été faite pour les tiges stockées dans le parc de l’usine pendant quatre périodes de durée différente. Les facteurs qui peuvent avoir influencé les niveaux de dommage sont discutés, et le rapport comprend des recommandations en vue de réduire les pertes de bois dues aux bris.
This report details the spacing (precommercial thinning) of three one-hectare blocks of Interior B.C. lodgepole pine and two one-hectare blocks of coastal western hemlock during 1987 and 1988. Each block received four different treatments during spacing. A Husqvarna 165RX clearing saw was used. Pre- and post-spacing stand densities, clearing-saw productivity, and costs are reported.
During 1992 and 1993 the Forest Engineering Research Institute of Canada (FERIC) observed three cable-yarding systems harvesting old-growth forest in the Walbran Valley on the west coast of Vancouver Island, British Columbia. FERIC compared the performances of the cable-harvesting techniques and evaluated them in terms of productivity and cost, quality of merchantable logs recovered, site disturbance, and among and quality of fibre left on the site after harvesting.
During the spring and summer of 1995, FERIC observed a series of tests aimed at reclaiming log sortyard residues and processing them as hog fuel for power boilers. These tests were conducted by MacMillan Bloedel Limited in the Port Alberni area on Vancouver Island. The equipment used in the tests consisted of excavators, a portable trommel, a metal detector/rock-picking conveyor belt, a portable hog and a crawler tractor. This report presents data on material composition, productivities and costs of the different treatments, and product analyses.
During the summer of 1996, FERIC observed a logyard residue operation system working in the central-interior of British Columbia. The primary equipment used were a trommel screen and a single-knife destoner. FERIC classified the logyard residues, observed productivity, calculated costs and determined the efficacy of separation for the system.
