All good points there. What about the HempBLOCK system? It looks like it's free on many of the issues with the  JustBioFiber product.

Interesting, I hadn't seen that one. Looks like a similar product just no plastic structure inside. What's your intended purpose for it?

I'd like to determine if it's a good alternative to building with ICF. It appears have many of the same benefits and maybe more DIY friendly, eco-friendly, pest resistant, etc. I'm still trying to find more info on finishing options, moisture control, below grade use, flooring systems, etc.

Not having worked with it we really aren't in a position to comment too much about it, but a few things to consider - they would not be airtight, so you would need an air barrier for sure. ICF is extremely airtight, that's one of its benefits. The down side of ICF in our opinion is less about the EPS foam and more about the carbon footprint of the concrete. If you were able to source carbon capture concrete that is one way to bring ICF right into the folds of 'green building'.
