Questions first, explanation underneath,

1. Are tetra-pak containers actually better for the environment? Or is it a bit of a con?

2. Would powdered Oat milk be better than tetra-pak, or other containers?

I'm getting into Oat milk, been a long time coming, finally just getting on and doing it.

We've ordered some Nimbus powdered online. But for now I've been drinking from the Tetra-pak Oat milks. Brands were Vitasoy and Oatley (apparently they're shipped from Europe? Wtf?).

I looked up thinkstep anz's comparative assessment of tetra-paks impacts and it comes out top. But this seems about as independent as a trouts flipper, so i'm not sure i trust their conclusion.

Any answers, or guidance would be muchly appreciated. :)
