Plastic Free July Day 28

47-53. Zip lock bags

Plastic Free July

I went to the markets to buy sourdough bread. I can’t really eat a whole loaf of bread quickly enough before it goes stale, so I have to freeze some of it. I used to use single use cling film/plastic film/sarin wrap to wrap my loaves of bread up in before freezing, but I have recently shifted to zip locks, because at least they are sort of reusable. But I guess the question is:

Which has less impact: aluminium foil or a zip lock plastic bag?

I think aluminium foil has a larger energy footprint to produce. Generally though, you can really only use it once before it tears. But the foil itself *is* recyclable, if it’s clean and as long as your country’s waste system actually recycles it.

A plastic bag is petrochemical derived. A zip lock bag I can reuse multiple times. Again, it *is* recyclable, if it’s clean and as long as your country’s waste system actually recycles it.

What would you do?

Buying bread on a “as needs” basis isn’t really an option, because sometimes I just get super busy and I just need something in the freezer to pull out if I need to.
