Are Soylent 2.0 bottles reusable?

I couldn’t find this topic when searching for it so please excuse me if this has been brought up before. Are the Soylent 2.0 plastic bottles reusable? What kind of plastic are they made of? (#7 “OTHER” isn’t very specific).

In short, can I keep the bottles and safely reuse them as water bottles, etc.?

Should be okay to reuse. The main plastic used in the bottles is high density polyethylene (HDPE), the same as used for distilled water or refrigerated milk and juice at the grocery. This is what the 2 at the bottom of the bottle stands for. There is also an barrier layer of another plastic in there (hence the 7 on the bottom of the bottle) which blocks oxygen and prevents spoilage and which is why Soylent lasts a year without refrigeration. Typically the oxygen barrier layer is sandwiched in between layers of HDPE, so that the only plastic in contact with the Soylent (or your water) would be HDPE. I think HDPE is entirely safe for reuse - I’ve got a couple old gallon HDPE bottles I use for water in my own fridge.


I’ve been refilling mine…

Just use glass. With glass you don’t even need to think about it.


That wasn’t the question though.
