Peanut butter squeeze tubes?

I and 5 friends are headed down to do the Torres Del Paine O trek this coming February and I'm planning the food. It's a pack-in pack-out scenario. No garbage cans. I'm wondering what you all think about the Jif peanut butter squeeze pouches. On one had, they're more packable than the plastic jars, but on the other, they become useless trash themselves and are wasteful. An advantage of a jar is that it's both recyclable and can be used as a trash stuff container, where it can be crammed full of other trash and then closed up.

Thoughts?
