Production of compressed wood with target quality indicators from different parts of tree trunk

open access: yesIOP Conference Series: Earth and Environmental Science, 2019
Abstract Wood species has great influence on the service life and quality of compressed wood. Currently, the industry lacks high-quality wood, so one of the solutions to this problem is the possibility of expanding the species composition used for the manufacture of compressed wood. The predominant group of species is soft hardwoods.
