Abstract
Methods for producing structural materials from lumber are provided. The methods use an oxygen pre-treatment or a carbonate pre-treatment followed by densification via thermal compression to produce structural materials with strong mechanical properties. The pre-treatments are able to partially delignify the lumber without substantially adversely affecting the mechanical properties of the subsequently densified wood.
