This is a genuine question I've been wondering about, but isn't the glue basically the same as the lignin that holds the wood (and I assume bamboo) together naturally. If it's not, could it be?
This applies to a lot of wood products like plywood and MDF not just bamboo.
In wood fiber insulation, some factories do manage to use the wood's own lignin to keep the insulation batts together, though apparently it's harder to manage for very thick batts.

Looks like some people are investigating it:
