For a week opt for items with less packaging.
More About The Challenge
Packaging from the things we buy forms a huge part of what ends up in landfills. That's not to say packaging is necessarily evil - it plays an important part in keeping our products fresh, hygienic and in good condition - but items can often have more packaging than they really need.
This challenge is to try to reduce packaging as much as possible for the week, either by looking for the same products with less packaging or by choosing alternatives - think loose potatoes instead of a bag of ready-made fries. Alternative responsible packaging (such as packaging that uses less plastics, can be recycled or is biodegradable), also falls under this challenge.
A lot of fresh fruit and vegetables can be bought without plastic wrapping in supermarkets. If you can't find what you're looking for responsibly packaged in a supermarket, try a local farmers market instead.
You may have a shop nearby that allows you to fill your own reusable containers with non-perishable goods such as rice, pasta, cereals etc. These often charge by weight with savings compared to the same products packaged in supermarkets.
