Integrated processing: An approach towards small diameter logs utilization and product diversification for commercial forestry in Tanzania
To meet the ever-increasing demand for timber, it is necessary to maximize the utilization of trees. Forestry practices have traditionally harvested only large-diameter trees (DBH > 25 cm), overlooking the vast potential residing in small-diameter stems (DBH < 15 cm) and the top parts of large-diameter trees. This issue is also evident in Tanzania, causing the industry to face underutilization of small-diameter...
