The important question is weight. Otherwise this board is strong enough to use on interior walls where moisture is no issue. Those walls include its usage as cladding under waterproofed siding. You do not wish to replace particle board so much as oriented strand board either. I think this may well be good enough and the market is much larger.
At worst you may need to adjust thicknesses.
The critical thing is that this board will resist termites. Throw in metal framing and you are actually good to go. You have a strong structure able to handle gyproc and structural weight and built as we conventionally do.
Rice husks may find use in cheaper, greener, longer-lasting particleboard
