Abstract

This study determined timber volume and timber value recovery of different plantation sawmill technologies. Data were collected from four sawmills in three forest plantation clusters. A two-way ANOVA was used to test the difference in performance between sawmill technologies and the combined effect of sawmill type and log diameter on performance. Sawmill technology significantly (p < 0.05) affected timber volume recovery and value recovery. The medium band sawmill had both the highest volume recovery (43%) and value recovery (209,700 UGX/m3) whereas the mobile circular sawmill had both the lowest volume recovery (26%) and value recovery (90,000 UGX/m3). The interaction effect of sawmill technology and log diameter significantly (p < 0.05) affected timber volume and value recovery. Mean timber volume recovery of sampled sawmills was 32% while value recovery was 123,800 UGX/m3. Studies on effect of market demands and sawyer’s skills on volume, value and throughput and how they can be optimized to improve profitability and sustainability of the resource are recommended.
