Processing Pruned and Unpruned Eucalyptus globulus Managed for Sawlog Production to Produce High Value Products
7th December 2004
Processing trials were conducted in conventional mills using logs from plantation-grown Eucalyptus globulus to produce appearance-quality solid timber. The trees harvested were selected to represent final harvests from three different management regimes. The objectives were to: determine log quality and yields based on Victorian log grades from the three stands; calculate the recovery of dried timber and mill door log values using back-sawing and quarter-sawing strategies; compare product quality and log values of pruned and unpruned logs; and identify factors limiting recovery and processing efficiency.
For pruned logs the estimated mill door log values are $145, $98 and $78 for B, C and D-grade logs respectively.
For un-prunned logs the estimated mill door log values are $80, $71 and $53 for B, C and D-grade logs respectively.
