“doused in flame retardant” isn’t mentioned in the source as far as I saw, plus it would affect the eco-friendly, workability, cost effectiveness, and biodegradability benefits mentioned (though the last one is worthy of debate as a pro or con in the first place). Everything has its tradeoffs unfortunately. This could be the better side for some surely.
From what I have read they are using a loam layer on both sides of the wall, I doubt that this affects eco-friendliness and biodegradability. And they are F90 certificated. source
