Abstract
Logging residue can be defined as any form of wood, which under the highest stage of technological development could
be used in manufacturing but is left in the forest during logging. Lumber production from logging residues of a previous logging
activity by a timber firm was undertaken with the objective of determining the suitability of utilizing buttressed-stumps as raw
material for the timber industry. A horizontal mobile bandsaw machine was used to process the buttressed-stumps into lumber. The
machine was characterized by a thin-kerf sawing technology (kerf-width 1.6 mm) compared to the conventional bandsaw machines
of kerf-widths ranging from 3.0-4.5 mm. Lumber value and volume yields, fuel consumption rate, frequency of tool replacement and
lumber production rate were assessed. Results indicated that there is the potential to increase timber production from logging residues
by utilizing buttressed-stumps. Lumber value and volume yields of eight timber species investigated in this study ranged from 5%-31%
and 34%-54% respectively. Fuel consumption rate which increased with increasing wood density, ranged from 5-14.5 liters/m3
of
lumber produced. Frequency of saw replacement increased with increasing wood density. The number of saws required to produce
one cubic meter of lumber, ranged from 1 to 7. Lumber production rate ranged from 0.10-0.38 m3
/hour, increasing with decreasing
wood density.
