This study assessed sawmill efficiency for olive (Olea europaea L.), black locust (Robinia pseudoacacia L.), and chestnut (Castanea sativa Mill.) logs in Southern Italy evaluating the impacts of defects like taper, ovality, sweep, and fluting on sawing yield. Taper was the most significant defect, especially for olive and chestnut logs. Black locust showed stable yields (70%), highlighting its commercial potential. The findings emphasize the importance of selecting high-quality raw materials and optimizing cutting techniques to reduce waste and enhance the economic value of Mediterranean hardwoods.
