“…An international review of literature highlighted that little has been published about the financial performance of spindleless rotary veneering and LVL manufacture, including processing coefficients, costs of production, and NPV estimates. There is some international literature reporting recovery of veneer from log volume from small and large diameter softwood and hardwood logs [61][62][63], and the levels of adopted in this case study are consistent with these.…”

In subtropical eastern Australia, the declining availability of traditional, large hardwood native forest logs has motivated hardwood sawmills to explore potentially utilising small logs in the manufacture of veneer-based engineered wood products (EWPs), such as laminated veneer lumber (LVL). An aspatial mathematical model that maximises net present value (NPV) over a 30-year project life has been applied to estimate the financial performance of LVL manufacture in this region. Of particular interest was how facility location affected financial performance, and whether distributed production of veneer (close to the log resource) and LVL (distant from the log resource) may be more profitable than integrated production under some circumstances. While integrated production of veneer and LVL near the resource maximised NPV, distributed production was found to be more profitable than integrated production in situations where the LVL manufacturing facility had to be located relatively far from the resource. Nevertheless, the level of value-adding and processing scale had a greater impact on financial performance than facility location. The analysis also highlighted that log procurement strategy substantially affected financial performance. Encouragingly for forest growers and wood processors, utilising large volumes of small diameter logs, was important for maximisation of NPV of larger-scale LVL facilities.

“…Overall volume recovery of dry, graded veneer was 44.2% (ranging from 38.1 to 49.5%). These recovery values are low when compared to the 58% recovery reported by Belleville et al (2018) in a 7-year-old stand of E. pellita in Laos, and when compared to the 55% recovery reported by McGavin et al (2014) for 13-year-old E. pellita with average SEDUB of 20.0 cm. The result shows that recovery was paradoxically lower in larger diameter logs, suggesting that loss from large logs was due to issues regards the physical processing, so that optimisation of rotary peeling of plantation grown logs is required to improve productivity (Bleron, 2012; McGavin et al 2014).…”

Plantation-grown, high-value timber species producing high-value end products are key to optimising land utilisation in Sabah and Sarawak states in Borneo, Malaysia, while meeting the demand for downstream processing. Eucalyptus pellita is one such species suitable for the tropical climatic conditions and exhibits considerable potential for solid wood and veneer production. The characteristics of E. pellita grown in Sabah, demonstrate the need for an appropriate silviculture management and downstream processing strategy to optimise the quality and quantity of veneer and sawn board. Recovery from E. pellita resources has demonstrated the average volume recovery of dry-graded veneer ranged from 38.1 to 49.5%, whereas the average dried board volume ranged from 48.5 to 57.9%. If E. pellita is to be grown on short rotations as a peeler resource, an appropriate pruning regime is needed to maximise the volume of clearwood. The greatest cause of volume loss was end-splitting in the recovery of veneer and solid timber.

“…Recent research has demonstrated the potential to use emerging spindleless veneering technologies to process hardwood plantation logs with sizes and qualities previously considered unable to be efficiently processed (McGavin et al 2014a,b;Peng et al 2014;McGavin et al 2015a,b;Leggate et al 2017;Belleville et al 2018). The research has shown that this new approach can process small-diameter logs and is able to yield recovery rates that are higher than what is achieved through other processes.…”

Comparison of processing methods for small-diameter logs: Sawing versus rotary peeling

Currently there are limited markets in Australia for small-diameter native forest logs. This has resulted in much of this resource being underutilized and regarded as sub-optimal in quality and of low value. This is despite the fact that the wood properties are favorable for a wide range of high-value products. Traditional processing approaches either have not been able to accommodate small-diameter logs or the resulting product recovery is too low for profitable production. Alternative processing approaches are necessary to enable the efficient recovery of wood from this resource in a form that is usable for high-value product manufacturing. Processing small-diameter spotted gum (Corymbia citriodora) and white cypress pine (Callitris glaucophylla) logs into rotary veneer using new spindleless veneering technology has been demonstrated to yield more acceptable recoveries compared with more traditional sawing approaches. The veneer processing approach was also found to be less impacted by the diameter than sawing, with more consistent recovery rates across the three small-diameter log groups included in this study. The resulting veneer, especially the spotted gum veneer, had visual qualities and mechanical properties well suited to the manufacturing of veneer-based engineered wood products.
