Fox has already pointed you to another thread. I was just wondering what piece you are wondering about for RMH and Straw bale building? The fire hazard? If that is the case, I would point out that they built a RMH in a mobile home that is arguably as flammable as a strawbale house with lime plaster.

I say raw, but I actually ferment it in a large trough of water for a few weeks, rinse it in rainwater or the creek, and let it sun-dry on a concrete slab. It is my understanding that this cleans some, but not all the lanolin off, removing grime, and leaving an even protective coating.
It started as an experiment 5 years ago, and I have been pleasantly surprised to have zero problems. No pest, no odor, just an incredibly high-performing loose-fill insulation material.

As well as the processing to make the fleece into a homogeneous product I gather most are also mixed with plastic fibres to give consistent loft. It does seem like a real opportunity to join the circle making use of a waste product - win-win, but certainly in a house (which we are considering) I am worried about the possibilities of moths moving in.
I think the main problems with Borax are to do with it being used in laundry and the associated contamination of water, so if you were using it for building and didn't have too much liquid waste to dispose of you may be able to buy and use it OK. I did find at least one site online here, which might be worth a try. They do say:
This product has been reclassified by the ECHA as Reprotoxic Category 2 and as such is not available to the general permies. Borax can only be purchased by Professionals and by trade and business users or for scientific research.
but I don't know what checks they might do, so it may be worth a shot as a known good treatment that isn't too toxic when used responsibly.

I wonder if it's "restricted" in the same way that many things here are. If you can prove it's for agricultural or building use, you can buy it. Might be worth asking at the local farm shop.
