residual veneer material of rubber wood (Hevea brasiliensis
Mull. Arg.) and falcata wood (Falcataria moluccana), and the
authors concluded that, based on the results, strand boards
obtained from rubber and falcata have the potential to be
commercialised.

In the US, a work investigated the feasibility of using western
juniper (Juniperus occidentalis) as a material to manufacture
oriented strand board (OSB) panels, and according to the
authors, the properties of the juniper panels were found to be
equivalent or slightly superior to those of the southern yellow
pine panels at the same density level, except for the MOE.
