Do plastic earthbag bags off-gas fumes like VOCs, etc.?
(Owen) I don’t really know. There’s no discernible smell, and I’ve never read or heard anyone warn of this. A quick search on Google didn’t turn up anything. It’s best to avoid all synthetic materials as much as possible, although in this case most people seem to agree the benefits of earthbags far outweigh any negatives. And keep in mind, the bags make up just a tiny percentage of the over all structure. And even then, they’re buried behind thick plaster. C: Superadobe bags, like most sandbags (earthbags), are made of Polypropylene. If you google for Polypropylene MSDS (material safety data sheet) you’ll see that the only concerns for safety come from burning polypropylene in unventilated spaces (and coming in contact with hot, melted , burning plastic). It is a very safe material; its used for everything from water bottles, pill bottles, candy containers, yogurt containers, plates/forks/spoons, blankets, shirts thermal underwear. 100% Polypropylene is not recommended for clothing/bed
