The economic consequences of resin defects are significant as they are a major cause of lost recovery and sawn product rejection for solid wood processors.

This project assessed tools needed to segregate badly affected logs. It modelled resin defect impacts on machine graded structural sawn wood recovery using external indicators, and tested the efficacy of a range of internal log scanning systems. Both lines of research aimed to identify logs that will not produce enough value added product recovery to justify sawing and processing costs.
